Everything for your Pet<br />

Having a pet changes your perspective on<br />

life. At first glance this might mean limiting<br />

your activity, needing to be home to care<br />

for the fur baby. On the other hand it can<br />

broaden your horizons, taking walks in<br />

all weathers to new places, getting more<br />

exercise and fresh air. Which ever way you<br />

look at it, the rewards of companionship<br />

and new experiences are beneficial for<br />

both sides.<br />

As the largest and most important meeting<br />

place for pets and supplies this year,<br />

the Interzoo international exhibition in<br />

Nuremberg, Germany, is fast approaching.<br />

The Interzoo will again offer the most<br />

comprehensive product overview in all<br />

respective sectors in the ever expanding<br />

pet industry, including the introduction of<br />

new products and trends.<br />

Just recently the Interzoo organizer WZF<br />

(Wirtschaftsgemeinschaft Zoologischer<br />

Fachbetriebe GmbH) announced a new<br />

record, with the number of exhibitors<br />

exceeding the 2,000 mark. Due to the<br />

consistently high demand, the remaining<br />

exhibition space has now also been<br />

allocated. Well over 2,000 companies from<br />

about 70 countries will showcase their<br />

products and solutions in 14 exhibition<br />

halls that cover an overall exhibition space<br />

of more than 140,000 square metres.<br />

“The sold-out Interzoo halls that break<br />

records with regard to exhibitor numbers,<br />

exhibition space and internationality<br />

show the huge pulling power of Interzoo<br />

for the gradually growing international<br />

pet supplies industry,” says Gordon<br />

Bonnet, Managing Director of WZF<br />

and ZZF (German Pet Trade & Industry<br />

Association, the institutional sponsor<br />

of Interzoo). “For trade visitors, there is<br />

no better opportunity on the globe to<br />

experience first-hand the incredible array<br />

of new products and exciting companies,<br />

to build networks, and to gain inspiration!”<br />

There will be the usual strong international<br />

presence, including 15 national pavilions<br />

and a total overseas exhibitor contingent<br />

of 86% giving an unrivalled overview<br />

of the global market. “The stronger<br />

demand across all continents shows<br />

how important Interzoo is as a showcase<br />

for innovation and a gathering place for<br />

industry decision-makers from all around<br />

the world,” says Dr Rowena Arzt, Director<br />

Exhibitions at Interzoo organizer WZF.<br />

Ian D. Healey, Editor-in-Chief<br />

These record breaking figures underline<br />

the importance of Interzoo as the central<br />

point of the worldwide pet supplies<br />

industry and as a creative force for ideas<br />

and insights in the months ahead. As<br />

the number of domestic pets continues<br />

to grow, so the need to feed, house and<br />

entertain them also increases. Interzoo<br />

gives plenty of input – and a whole range<br />

of new choices and ideas to further expand<br />

the benefits of the special companionship<br />

and joint experiences with our existing<br />

and maybe new pets.<br />

Decreasing the impact on the environment is a hot topic, no<br />

less so than in the pet food industry, especially as the number<br />

of individual pets is still continuing to grow. This explains<br />

the growing market demand for trends like natural, organic,<br />

industry, it is important for us to find sustainable alternatives<br />

to animal-derived ingredients for pet food. The full story is on<br />

Metallic impurities jeopardize the integrity of pet food,<br />

necessitating the rejection of affected batches. These<br />

contaminants can originate from various sources, including<br />

transportation vehicles used for product delivery. Internal<br />

contamination may occur during processing, grinding, or<br />

abrasion within the manufacturing plant. The application of<br />

magnetic separation equipment proves instrumental in reducing<br />

ferrous metal contamination issues. See page 30 for more.<br />

New Functional Ingredients to<br />

Improve Texture and Natural<br />

Coloring<br />

by Maike Rakebrandt, Senior Product Management Companion Animals (Equine & Pet), Leiber GmbH (<strong>2024</strong>)<br />

Leiber YeaFi® products combine brewers’<br />

yeast benefits with the functional<br />

properties of fibers o. a. from spent grain<br />

and sugar beet pulp. In practical use<br />

in dry kibbles and vegan or vegetarian<br />

applications a positive impact on coloring,<br />

smell and texturization were seen. Leiber<br />

YeaFi® were also used as dilutatant<br />

of spray dried hydrolyzed liver or as<br />

substitute for pure dried brewer´s yeast<br />

because it is less hygrosgopic. The fiber<br />

content in Leiber YeaFi® are important<br />

also from an economic point of view. Pet<br />

food products compete more and more<br />

often with food products for natural fiber<br />

sources which directly increases the price<br />

of the pure natural fiber ingredients.<br />

The snack category is the second most<br />

sold, right after dry food. The market share<br />

for semi-moist and baked snacks has<br />

been rapidly increasing. In oven-baked<br />

snacks the moisture level is reduced to<br />

10%. Semi-moist snacks are products that<br />

Table 1: Leiber YeaFi® nutrition and fiber profiles in %<br />

contain 14-30% moisture. Therefore, it<br />

is important to explore ingredients that<br />

have impact on the texture and quality,<br />

and such that are naturally contribute to<br />

prevent microbiological spoilage.<br />

Material and Methods<br />

Leiber YeaFi® is rich in dietary fiber and<br />

brings at the same time the brewers’<br />

yeast with a high level of protein into the<br />

formulations. Using blended products at<br />

the 3-4% inclusion levels can contribute<br />

to the 1,2-1,6% of brewers’ yeast in the<br />

formulation while at the same time could<br />

replace use of fiber up to 2%. For this test<br />

we used different types of Leiber YeaFi®.<br />

Leiber YeaFi® BTR based on brewers‘ yeast,<br />

spent grain and beet pulp and Leiber<br />

YeaFi® AB-F with brewers’ yeast, apple<br />

pomace and beet pulp. Both contain a<br />

high soluble fiber fraction (Table 1).<br />

After a technical pre-test in the lab Leiber<br />

YeaFi® BTR and Leiber YeaFi® AB-F were<br />

tested in semi-moist functional snacks<br />

included at 5 and 10%.<br />

The semi-moist snacks were formulated<br />

with the following declaration: poultry<br />

meal, potato starch (pregeled), pea<br />

starch (pregeled), glycerin, pea fiber,<br />

preservatives. In test samples with 5%<br />

test product, pea fiber was completely<br />

exchanged. In the test samples with<br />

10% test product the pea fiber was fully<br />

replaced and 5% of pea starch was reduced.<br />

The nutritional analysis showed that when<br />

Leiber YeaFi® products were added to the<br />

formulations, crude fiber were decreased,<br />

but protein content and soluble fiber were<br />

increased in the snacks.<br />

The technical analyses of the test and<br />

control snacks were done in three periods,<br />

immediately, seven days and a month after<br />

the production. Following parameters<br />

were analysed: moisture, pH, aW, texture,<br />

firmness, energy, adhesiveness and<br />

stickiness. Texture analyses are important<br />

for both impacts on physical quality but<br />

also on sensory analyses like palatability.<br />

Additional to the semi-moist snack, vegan<br />

oven-baked snacks were produced in a<br />

two-step baking/drying, to imitate the<br />

commercial baking process. The moisture<br />

level was reduced to 10%. Reduction of<br />

moisture is important for shelf-life and<br />

prevention of microbial growth, also in<br />

baked snacks. Leiber YeaFi® BTR and Leiber<br />

YeaFi® AB-F were formulated by adding<br />

10% into the test recipes, which were based<br />

on potatoe flakes, oil and pea meal. Leiber<br />

YeaFi® products substituted 10% of the pea<br />

meal. Moisture, pH, aW, texture, baking loss<br />

and shrink percent were measured.<br />

The baking loss is the weight of the snacks<br />

before and after baking. The difference<br />

indicates the loss of evaporation. In<br />

addition, the weight change before<br />

Results<br />

In the semi-moist test Leiber YeaFi® BTR,<br />

followed from Leiber YeaFi® AB-F showed<br />

high water absorption properties and<br />

moisture holding capacity after cooking<br />

and retorting. This is due to the higher<br />

level of the soluble fibers. Increasing the<br />

concentration of the Leiber YeaFi® BTR<br />

and Leiber YeaFi® AB-F samples caused<br />

an increase in the viscosity/hot water<br />

absorption.<br />

Photo 2: Leiber YeaFi® products increased the shininess and natural coloring in oven-baked snacks<br />

Both test products performed as great<br />

texturizers improving the texture and<br />

shape and reducing the stickiness of<br />

the snacks and knives had a better cut.<br />

The 10% inclusion of Leiber YeaFi® BTR<br />

and Leiber YeaFi® AB-F decreased the<br />

use of energy (SME) and significantly<br />

improved capacity. All test ingredients<br />

improved the snacks’ appearance,<br />

coloring and shine. Leiber YeaFi® BTR<br />

and Leiber YeaFi® AB-F had the most<br />

positive impact on the snacks. Increased<br />

inclusion (10%) increased the impact.<br />

The shape was more distinctive. In<br />

addition, both products increased the<br />

shininess of the snack and gave more<br />

brown color (Photo 1). The variation<br />

in shape and natural coloring were<br />

significant.<br />

Also in the vegan oven–baked snacks<br />

the color change was significant<br />

when changing 10% of pea meal with<br />

the blended brewers’ yeast products<br />

(photo 2).<br />

Leiber YeaFi® BTR and YeaFi® AB-F had<br />

the tendency to reduce water activity<br />

(Figure 1). Inclusion of 10% significantly<br />

decreased water activity of the snacks<br />

Figure1: Water activity (aW), after a month storage in semi-moist snacks<br />

despite the added moisture during the<br />

extrusion.<br />

The water activity after LT (low temperature)<br />

in vegan, ovenbaked snacks was naturally<br />

high for all test samples (Figure 2). After<br />

the HT (high temperature) treatment, the<br />

test products reduced the water activity<br />

and moisture content more efficiently<br />

compared to the control biscuits. Due<br />

Figure 4: pH values for vegan, oven-baked snacks, with low<br />

temperature (LT) and high temperature (HT) baking.<br />

to the higher moisture reduction during<br />

baking the weight loss and shrinkage were<br />

higher for the Leiber products.<br />

Increasing the inclusion level of Leiber<br />

YeaFi® products decreased significantly<br />

the pH of the semi-moist snacks (Figure 3)<br />

during the whole test period. Decreasing<br />

pH in semi-moist snacks has a positive<br />

impact on the preservation of the product.<br />

In vegan oven-baked snacks the pH was<br />

analyzed for both high (HT) and low (LT)<br />

temperature treatments (Figure 4). The<br />

addition of 10% Leiber YeaFi® significantly<br />

decreased the pH of the biscuits also. This<br />

indicated again a preservation potential<br />

of the test products.<br />

Leiber YeaFi® products also had an impact<br />

on the textural properties of the semimoist<br />

snacks. The firmness of the snacks<br />

decreased with the reduction of the pea<br />

starch in the control kibbles.<br />

This was expected as starch is one of the<br />

main factors to increase the hardness<br />

in the snacks. When used Leiber YeaFi®<br />

BTR and Leiber YeaFi® AB-F firmness<br />

increased with inclusion level (Figure 5).<br />

The inclusion level (5 or 10%) didn’t have<br />

significant effect on the firmness as did<br />

the source of the fibers.<br />

After technical tests, the semi-moist<br />

snacks were given to a dog home panel<br />

(n=10). Taste preference was organized<br />

in the form of first-choice testing for<br />

two days and then statistically grouped<br />

and analyzed (Figure 6). All Leiber YeaFi®<br />

snacks were tastier then the controls, and<br />

dogs were keen on consuming them. The<br />

highest preference was shown towards<br />

Leiber YeaFi® BTR. Also the vegan ovenbaked<br />

biscuits were tested with the<br />

dogs. All biscuits were accepted well.<br />

Here Leiber YeaFi® AB-F had the highest<br />

preference.<br />

Conclusion<br />

Leiber YeaFi® products are an interesting<br />

concept for application in semi-moist<br />

and vegan oven-baked snacks. They have<br />

a positive impact on production as they<br />

effiiciently reduce stickiness, and improve<br />

texture, appearance, pH, coloring, shiness<br />

and taste of the semimoist snacks. From<br />

an economic point of view the production<br />

capacity was significantly higher<br />

compared to the controls. The inclusion<br />

of Leiber YeaFi® products in vegan ovenbaked<br />

snacks also resulted in a significant<br />

change of the color and reduction of the<br />

pH. The baking process reduced moisture<br />

more compared to control. The reduction<br />

of pH and water activity in both snacks<br />

indicating that Leiber YeaFi® products give<br />

a sort of natural preservation effect and<br />

the baking time can be reduced therefore<br />

the energy consumption can be lower.<br />

Functional Ingredients as a Natural<br />

Support for Weight Management<br />

in Pets<br />

Photo: Beneo<br />

For many years, being overweight or obese<br />

was a human concern. These days however,<br />

more and more companion animals are<br />

struggling with this condition. Here Dr<br />

Maygane Ronsmans, Product Manager<br />

Animal Nutrition at BENEO, explores how<br />

functional ingredients can help as a natural<br />

support for weight management in pets<br />

and why the choice of carbohydrate and<br />

fiber matters when it comes to long-term<br />

health.<br />

Pets are increasingly overweight<br />

or obese<br />

Numbers of overweight and obese<br />

companion animals have steadily increased<br />

over the last few decades and now exceed<br />

50% in Western countries. i Recent statistics<br />

from the US have even classified 6 in 10<br />

dogs and cats as overweight or obese. ii<br />

As with humans, there are many serious<br />

health consequences for overweight or<br />

obese pets. These include cardiovascular<br />

and metabolic diseases (e.g., glucose<br />

intolerance, diabetes), or skeletal<br />

associated disorders, leading to a negative<br />

impact on the pet’s - and owner’s - quality<br />

of life.<br />

Pet owners are well aware of the dangers<br />

surrounding having overweight or obese<br />

companion animals, and many like to opt<br />

for a preventive approach when it comes<br />

to managing their pet’s weight. A recent<br />

global survey conducted by FMCG Gurus<br />

on behalf of BENEO showed that 3 in 4<br />

pet owners worldwide were concerned<br />

with their pet’s weight iii and around 4<br />

in 5 agreed that an on-pack claim about<br />

helping to control their pet’s weight<br />

naturally affects their purchase intention<br />

of a pet food product to some extent. iv<br />

There is therefore a market opportunity for<br />

functional ingredients that can help with<br />

weight and blood glucose management.<br />

Functional ingredients as part of<br />

the solution<br />

Like in humans, prevention of obesity is<br />

always better than cure, and a balanced<br />

diet should remain the ‘gold standard’.<br />

Nevertheless, when weight loss is<br />

required, a multi-pronged approach that<br />

combines exercise along with energyrestricted<br />

diets is often key. In the context<br />

of obesity, the choice of nutrients in pet<br />

food can also make a difference, and<br />

including functional ingredients in a pet’s<br />

diet - such as slow-release carbohydrate<br />

isomaltulose and prebiotic chicory root<br />

fibers - can help with weight and blood<br />

glucose management.<br />

Carbohydrate choice matters<br />

Carbohydrates are an inherent part of our<br />

pets’ diet nowadays. Though, carbohydrates<br />

have not been created equal and they<br />

differ in composition, digestive properties<br />

and therefore glycaemic effects. A case in<br />

point is that high glycaemic carbohydrates,<br />

such as sucrose or cooked starches, are<br />

rapidly digested and absorbed in the first<br />

part of the small intestine, resulting in a<br />

fast and high blood glucose response.<br />

Low glycaemic carbohydrates on the other<br />

hand, are digested more slowly and lead<br />

to a lower blood glucose response. Having<br />

a slower blood glucose supply results in<br />

more balanced glycaemia, lower insulin<br />

peaks and overall better metabolic health.<br />

A 2012 study with dogs has further shown<br />

that low glycaemic diets can support<br />

weight loss. v<br />

For pet food producers looking for low<br />

glycaemic carbohydrates, isomaltulose<br />

can become a key part of their ingredient<br />

toolbox. Isomaltulose is a disaccharide of<br />

glucose and fructose derived from sugar<br />

beet that is characterised by a stronger<br />

glycosidic bond than that of standard<br />

sugar. Due to this specific linkage, it is<br />

more resistant to enzymatic hydrolysation<br />

in the intestine, therefore inducing lower<br />

glycaemic and insulin responses than<br />

regular sucrose as demonstrated in many<br />

species (e.g., humans, rodents and pigs).<br />

A scientific publication from 2023 about<br />

three studies from Corbee et al vi , has<br />

confirmed that isomaltulose is a suitable<br />

low glycaemic ingredient for use in dog<br />

food, triggering a lower blood glucose rise<br />

after consumption. The trials evaluated<br />

the digestion of isomaltulose as well as<br />

its glycaemic and insulinaemic effects<br />

in dogs, compared to other relevant<br />

carbohydrate sources. An in-vitro study of<br />

small intestinal tissue samples from three<br />

dogs showed that isomaltulose can be<br />

digested by canine intestinal enzymes,<br />

with a lower enzyme activity compared to<br />

high glycaemic carbohydrates, indicating a<br />

slower rate of hydrolysis.<br />

In addition, two in-vivo studies compared<br />

the effects of isomaltulose, sucrose and<br />

maltodextrin in dogs. The results showed<br />

that isomaltulose significantly lowered<br />

blood glucose and insulin responses,<br />

compared to maltodextrin or sucrose –<br />

even after continuous feeding. All in all, this<br />

property makes isomaltulose a particularly<br />

interesting solution with the potential<br />

to support metabolic health and weight<br />

management in dogs.<br />

go beyond the gut. For example, studies<br />

show that including Orafti® Inulin and<br />

Oligofructose in a pet’s diet can curb<br />

their appetite, improve satiety and hence<br />

xv, xvi, xvii<br />

decrease voluntary food intake. In<br />

doing so, chicory root fibers can help to<br />

maintain the healthy condition of a pet’s<br />

body.<br />

Additionally, since inulin-type fructans<br />

are non-digestible carbohydrates and<br />

dietary fibers, they do not trigger a rise<br />

in postprandial blood glucose or insulin<br />

concentrations. As a result, they support<br />

blood sugar management in dogs. What’s<br />

more, studies in dogs have shown that<br />

feeding them with chicory prebiotics can<br />

allow for a lower blood sugar response<br />

after a meal , and this benefit can extend<br />

to a subsequent meal taken hours later,<br />

even if that meal doesn’t include chicory<br />

root fibers; xx, xxi which is called the second<br />

meal effect.<br />

Quality production<br />

BENEO produces its functional<br />

carbohydrates, including isomaltulose, and<br />

chicory root fibers in state-of-the-art and<br />

food-certified processing plants, which<br />

enables the highest product quality to be<br />

continuously guaranteed. Also, the non-<br />

GMO sugar beets and chicory roots are<br />

sourced from farmers in close proximity to<br />

the production sites. Isomaltulose as well as<br />

Orafti® Inulin and Oligofructose are natural<br />

ingredients which are acknowledged as<br />

feed materials in the EU xxii . They are suitable<br />

for use in both dry and wet pet foods, or in<br />

snacks.<br />

With more and more companion animals<br />

struggling with being overweight or obese,<br />

it is no wonder that pet food producers are<br />

turning to functional ingredients, such<br />

as BENEO’s, to help owners resolve these<br />

issues. By choosing the right ones, it is<br />

now possible to support weight and blood<br />

sugar management in pets more naturally,<br />

whilst supporting their long-term health.<br />

New Production of Flours and<br />

Fats from Dried Black Soldier Fly<br />

Larvae Starts in Galicia, Spain<br />

The dried black soldier fly larvae used to produce the first batches come from the Bioflytech Group's other<br />

plant in Fuente Alamo, Murcia<br />

The company has recently obtained authorization for the production of flour, a milestone that marks a before<br />

and after in the production of this type of insect-derived products, where the Bioflytech group is a pioneer<br />

The products are aimed at animal feed, mainly pet food and the aquaculture sector<br />

Once the works have been completed and the necessary authorization has been obtained, the facilities in<br />

Galicia will produce 12,000 tonnes of larvae per year and will consolidate Bioflytech as one of the world leaders<br />

in the sector<br />

Bioflytech has started the production of<br />

flours and fats from dried black soldier fly<br />

larvae in its new facilities located in Palas<br />

de Rei, Galicia, north-western Spain. The<br />

company has started the activity after<br />

becoming the first Spanish company<br />

in this innovative sector to obtain the<br />

authorization to produce, transform and<br />

commercialize this type of product.<br />

The dried black soldier fly larvae, with<br />

which the rendering lines are being set<br />

up and the first batches of flours and<br />

fats produced, come from the company's<br />

other plant in Fuente Álamo, Murcia.<br />

These new facilities in Palas de Rei are<br />

now up and running after obtaining<br />

authorization for the production - by<br />

means of a drying process - of the<br />

products that make up the company's<br />

portfolio and which are mainly aimed at<br />

animal feed, especially pet food and for<br />

the aquaculture sector.<br />

Obtaining this authorization has been<br />

possible thanks to the hard work of the<br />

technicians involved in the project at all<br />

levels, from those who work at Bioflytech<br />

to those who are part of the national,<br />

regional and local administration. This has<br />

made it possible to achieve a milestone<br />

that marks a turning point in the<br />

production of protein meals from insects,<br />

where the Bioflytech group is a pioneer.<br />

After obtaining the necessary permits, it<br />

has been possible to start the production<br />

of flour and fat in the new facilities<br />

in Palas de Rei, which have state-ofthe-art<br />

technology to carry out the<br />

transformation of the dried larvae from<br />

Murcia. Thus, a rendering machine<br />

and a drying machine have come into<br />

operation, allowing the product to be<br />

transformed into flour, which is mainly<br />

used as a raw material for the production<br />

of pet food and aquaculture food. The fat<br />

is destined, on the one hand, for pig feed<br />

and, on the other, for the pharmaceutical<br />

and cosmetics industry, which uses it in<br />

the creation of soaps and moisturizing<br />

creams, among others.<br />

The facilities have also started up a second<br />

rendering machine of its own design and<br />

unique on the market, which will enable<br />

tailor-made flours to be manufactured<br />

with specific percentages of protein and<br />

fats according to the customer's demands,<br />

and which is set to revolutionize the<br />

production of protein flours from insects.<br />

These two rendering machines will be<br />

joined in the coming weeks by a third one<br />

that has already arrived in Palas de Rei and<br />

will be assembled in the next few days.<br />

In parallel to the start of the activity, work<br />

continues to complete the eight plants<br />

that make up the complex, which include<br />

the production plant, six larvae fattening<br />

plant and another for compost storage.<br />

About Bioflytech<br />

Moira Capital Partners<br />

acquired a majority stake in<br />

Bioflytech, established in<br />

2012 as a biotech company,<br />

in 2018. A year later, the<br />

Fuente Álamo facility in<br />

Murcia was opened.<br />

The support of the Xunta de<br />

Galicia and the City Council<br />

of Palas de Rei for the project<br />

determined Bioflytech's choice<br />

of this autonomous community to<br />

undertake its expansion, for which<br />

different locations in the north of Spain<br />

and even Portugal were considered.<br />

Bioflytech obtains four main products<br />

from the black soldier fly: dried larva,<br />

which is obtained after almost complete<br />

drying of the fresh larvae and has highly<br />

digestible protein and all the necessary<br />

components for the diet of poultry,<br />

fish and other animals; high protein<br />

meals; fats, which are obtained from the<br />

larvae without using chemical agents<br />

or solvents; and compost, obtained<br />

as a result of the biodigestion of the<br />

vegetable material produced during the<br />

fattening process.<br />

Bioflytech's dried larvae is a product<br />

especially designed as a feed diet for<br />

laying hens and broilers, while the<br />

protein meals are aimed at the petfood,<br />

aquaculture and poultry industries,<br />

and also to a lesser extent at animal<br />

feed for the fur industry. Fats are mainly<br />

used in animal feed, but also in the<br />

pharmaceutical and cosmetics industry.<br />

Compost is used as fertilizer.<br />

The surroundings are also being adapted,<br />

as the total plot is 140,000 square meters<br />

in size.<br />

Challenges for the company<br />

Once the necessary authorization has<br />

been obtained, the fresh larvae fattening<br />

process will also begin in Palas de Rei,<br />

which will allow for the production<br />

of a total of 12,000 tonnes per year.<br />

Subsequently, a new phase of expansion<br />

of the facility will be undertaken to<br />

produce 100,000 tonnes of fresh larvae<br />

per year.<br />

Meanwhile, at the Fuente Álamo facility in<br />

Murcia, not only will the activity continue,<br />

but an investment of 2.8 million euros is<br />

planned for the second half of the year to<br />

increase the production capacity of the<br />

hatchery that supplies larvae eggs to the<br />

facility in Galicia. At present, the Fuente<br />

Álamo facility produce 180 kilos of eggs<br />

Left: Dried black soldier fly larvae<br />

Right: Flour<br />

per month, which is already a milestone<br />

in the sector worldwide, given the<br />

complexity of guaranteeing stable and<br />

continuous production throughout the<br />

year. The objective with this expansion, for<br />

which all the permits have already been<br />

requested, is to reach 350 kilos of eggs per<br />

month, something unprecedented in the<br />

sector.<br />

This first Bioflytech plant in Fuente Álamo<br />

currently produces 4,000 tonnes of fresh<br />

larvae per year.<br />

Protein Choices to Lower Your<br />

Pet's 'Paw Print'<br />

Reducing your environmental impact by selecting more sustainable alternatives<br />

Photos: Barentz<br />

Decreasing the impact on the<br />

environment is a hot topic, no less so<br />

than in the pet food industry, especially<br />

as the number of pets is still growing. This<br />

explains the growing market demand for<br />

trends like natural, organic, vegetarian or<br />

even vegan pet food. Premiumization and<br />

humanization continue to drive the petfood<br />

category, an increasing demand for<br />

plant-based proteins could also be a result<br />

of more flexitarians as pet owners, as pet<br />

parents want their pets eating habits to<br />

be similar to their own. Ultimately, as the<br />

pet food industry, it is important for us to<br />

find sustainable alternatives to animalderived<br />

ingredients for pet food.<br />

Plant-based proteins<br />

There is a broad variety of plant-based<br />

proteins, which can be used to reduce<br />

meat proteins in pet diets, however it is key<br />

to keep an eye on the amino acids profile<br />

of plant-based proteins. From the plantbased<br />

proteins, soy protein has the most<br />

complete amino acid profile. Nevertheless,<br />

soya is not always so popular to use. This<br />

is because its acceptance varies from<br />

country to country; the possible reason<br />

behind this could be related to GMO and<br />

deforestation, even when there is also<br />

GMO free soy on the market, produced in<br />

Europe, without deforestation. Another<br />

aspect could be that soya can contain<br />

anti-nutritional factors. Soya concentrates<br />

and isolates can be used to avoid those<br />

problems.<br />

Pea protein is very popular, although it<br />

has very low values of methionine and<br />

cystine. To overcome this deficiency, it can<br />

be used together with rice, which is rich<br />

in methionine and cystine. Also potato<br />

protein is quite often used, because of its<br />

balanced amino acid profile. On the other<br />

hand, corn protein (corn gluten meal) is an<br />

incomplete protein, it is lacking in arginine<br />

and tryptophan. To overcome this, corn<br />

can be supplemented with other plantbased<br />

proteins to make the list of essential<br />

amino acids complete.<br />

In all cases of using plant-based proteins,<br />

keep an eye towards the levels of taurine<br />

and carnitine in the diet, even when these<br />

are considered as non-essential, both are<br />

really key for healthy dogs and cats.<br />

Functionality<br />

Beside the nutritional aspects, plantbased<br />

proteins can also be used for their<br />

great functional properties. Different<br />

types of soya concentrates or isolates<br />

have different levels of water binding,<br />

emulsifying and gelling properties. Those<br />

concentrates or isolates can be used to<br />

retain the water and fat during the entire<br />

technological process, with securing<br />

shelf life of the final product. Next to<br />

soya, also other functional proteins from<br />

pea, chickpea or faba beans can be used.<br />

Those are typically used for products such<br />

as paté, terrine, chunks and also for meat<br />

alternatives.<br />

Insects – fully circular<br />

Another alternative to animal-derived<br />

proteins are insects, which are a highly<br />

valuable nutritional protein source.<br />

Insects are also more sustainable for<br />

several reasons. Firstly, insects can turn<br />

low value feed materials and related byproducts<br />

into high value insect protein<br />

and oil. They are fed with by-products,<br />

not suitable for other livestock, which<br />

otherwise would have gone to lower<br />

value productions such as bio-refineries.<br />

Secondly, insect breeding is a zero-waste<br />

and circular process. There are three<br />

final products produced from insects:<br />

insect protein, insect oil and organic<br />

fertilizer. Insect protein and oil are used<br />

as natural and sustainable alternative<br />

ingredients in livestock feed and pet<br />

food. The frass, which is the manure and<br />

the leftovers from the insect breeding, is<br />

used as an organic fertilizer to grow new<br />

crops, of which again the lowest value<br />

by-products are used for feeding new<br />

batches of insects. This is a full circular<br />

model! However sustainability of insectbased<br />

ingredients can even go beyond<br />

circularity and upgrading of low value byproducts.<br />

Barentz has a range of plant-based and<br />

alternative proteins. Their technical team<br />

is ready to find together with pet food<br />

manufacturers the best solution, to lower<br />

the pet food ‘paw print’.<br />

Botanical Extracts: The Next<br />

Generation of Antioxidants (Part 1)<br />

by Cristina Murcia<br />

Introduction<br />

Botanical extracts are natural ingredients<br />

that contain diverse polyphenol type<br />

molecules. Some are well known for their<br />

endogenous and exogenous antioxidant<br />

abilities. In the European Union's<br />

regulatory framework for feed and pet<br />

food, until recently, only mixed tocopherols<br />

were registered as antioxidants.1 However,<br />

in response to the EFSA's 2022 Scientific<br />

Opinion, the European Commission has<br />

now approved rosemary extract as feed<br />

additive for cats and dogs, in the category<br />

of antioxidants. 2<br />

This article will focus on the exogenous<br />

antioxidant capacity of rosemary and olive<br />

extracts and the main reaction mechanism<br />

of their active molecules with the highest<br />

antioxidant potential.<br />

Rosemary extract<br />

Rosemary extract contains different<br />

diterpene molecules with antioxidant<br />

activity, from these, the one with the<br />

highest antioxidant effect is carnosic<br />

acid. Other molecules such as carnosol,<br />

rosmanol or epirosmanol have also some<br />

antioxidant capacities but less significant<br />

than carnosic acid. The reason for that<br />

is that all the above are decomposition<br />

products of carnosic acid, as we will see<br />

while explaining the simplified chemical<br />

reaction mechanisms.<br />

Oxygen Scavenger Mechanism:<br />

To prevent oxidation rosemary extract, or<br />

specifically, carnosic acid can scavenge<br />

singlet oxygen, an excited form of oxygen,<br />

and free radicals. While doing this carnosic<br />

acid will oxidize itself to form a carnosic<br />

acid quinone that by action of temperature<br />

or other catalysts will be transformed into<br />

carnosol. The carnosol molecule will further<br />

follow this path and will oxidise itself to be<br />

transformed into epirosmanol or rosmanol,<br />

depending on the stereochemistry of the<br />

reaction. 3,4 See Figure 1.<br />

Hydrogen Transfer Mechanism:<br />

Carnosic acid can also neutralize free<br />

radicals by following a different mechanism,<br />

by donating hydrogen atoms to stabilize<br />

lipid molecules (in figure 2 represented as<br />

ROOH). This type of mechanism is called<br />

hydrogen transfer mechanism. Here<br />

carnosic acid can neutralize the free radical<br />

activity of two lipid radical molecules<br />

(ROO°) to form a carnosic acid quinone. Like<br />

in the previous mechanism the carnosic<br />

acid quinone can be transformed into<br />

carnosol to provide additional antioxidant<br />

activity. Or the mechanism can follow a<br />

different pathway and lipid radicals can be<br />

stabilized by forming an epoxy quinone. In<br />

summary, the key message here is that one<br />

molecule of carnosic acid can neutralize<br />

two lipid radical molecules. 3<br />

What we can learn from the chemistry<br />

explained here is that carnosic acid<br />

can generate a variety of secondary<br />

antioxidants. This unique cascade-type<br />

process is likely to amplify the antioxidative<br />

power of carnosic acid and hence of<br />

rosemary extract and to constitute an<br />

Dr Cristina Murcia<br />

García gained her PhD in<br />

Chemistry with focus on redox<br />

reactions from the University<br />

of Bonn (Germany). Since then, she has specialized in<br />

managing oxidation in rendering and pet food products.<br />

She works as Technical Service Manager for Kemin<br />

improve raw materials and pet food safety and shelf-life.<br />

Besides, she develops tailor-made trials and protocols for<br />

customers and holds customer specific trainings on topics<br />

like oxidation, freshness, and food safety.<br />

effective defense mechanism.4 In sum,<br />

the main driver for the antioxidant activity<br />

of rosemary extract is carnosic acid.<br />

This means the higher the carnosic acid<br />

concentration in a rosemary extract, the<br />

better will be its antioxidant activity. The<br />

rest of the phenolic diterpenes will also have<br />

some antioxidant activity but lower than<br />

carnosic acid because, as we have seen, they<br />

are degradation products from the carnosic<br />

acid molecule. Besides, rosemary extracts<br />

contain also other antioxidants such as<br />

rosmarinic acid bringing more antioxidant<br />

power to the overall activity of this botanical<br />

extract.<br />

Olive extract<br />

Olive extract is another natural<br />

ingredient very well known for its health<br />

benefits and widely used for centuries in<br />

the countries of the Mediterranean area.<br />

Apart from its health or endogenous<br />

antioxidant and antimicrobial properties,<br />

recent research has shown the potential<br />

benefit of using olive extract as an<br />

exogenous antioxidant to prevent<br />

oxidation of fats, oils and fat containing<br />

matrices.<br />

Since olives are a raw material extensively<br />

used in human nutrition, the question<br />

arose if it could be economically suitable<br />

as an ingredient for the feed and pet<br />

food industries. Not all parts of the olive<br />

tree are used at the moment for human<br />

consumption. Among others, there are<br />

the leaves and there is the waste of the<br />

olive fruit after production of olive oil.<br />

Both co-products are rich in polyphenols<br />

with potential antioxidant activity.<br />

In olive materials we can find two<br />

interesting molecules for our antioxidant<br />

purpose: oleuropein and hydroxytyrosol.<br />

These two catechols have shown<br />

endogenous and exogenous free radical<br />

scavenging activity.⁵<br />

Although we can find both active<br />

ingredients in olive leaf and fruit, olive<br />

leaves are rich in oleuropein while olive<br />

fruits main ingredient is hydroxytyrosol.<br />

Oleuropein has shown an important<br />

antimicrobial effect as well as some<br />

endogenous antioxidant activity.⁶<br />

Nowadays there are a number of<br />

supplements in the market for human<br />

but also for petfood claiming immune<br />

system boost thanks to the properties<br />

of oleuropein (just type on your web<br />

browser pet food supplement with<br />

oleuropein and you will find several<br />

companies offering such products).<br />

Unfortunately, as technological additive<br />

to control oxidation of fats and oils,<br />

oleuropein as such has shown a poor<br />

antioxidant activity in comparison<br />

with hydroxytyrosol and other known<br />

antioxidants.⁷<br />

On the contrary, hydroxytyrosol has been<br />

demonstrated to be an ideal candidate to<br />

be considered as exogenous antioxidant<br />

to prevent the oxidation of feed and pet<br />

food relevant matrices.⁸,⁹ A few studies<br />

have proposed the mode of action of<br />

hydroxytyrosol, mainly by using radical<br />

scavenging reaction mechanism in<br />

which the hydroxytyrosol molecule can<br />

neutralized lipid radicals (ROO°). See<br />

figure 4.<br />

Kemin internal results have shown that<br />

the antioxidant activity of olive fruit<br />

extract can be enhanced by combination<br />

with known natural antioxidant<br />

molecules and that contrary to rosemary<br />

extract and carnosic acid, higher<br />

amounts of hydroxytyrosol in an olive<br />

extract do not necessarily mean better<br />

antioxidant activity.10<br />

Several studies have shown that olive<br />

fruit extract containing hydroxytyrosol<br />

but not only shows antioxidant<br />

activity comparable to that of pure<br />

hydroxytyrosol, perhaps due to the<br />

presence of active derivatives of<br />

hydroxytyrosol and other phenolic<br />

compounds which promote synergistic<br />

effects in the extract that are not<br />

available when using the pure molecule.<br />

Further research is needed to elucidate<br />

the mode of action of the antioxidants<br />

present in the olive extract.<br />

Emsland Group at Interzoo<br />


Interzoo <strong>2024</strong><br />

May 7-10<br />

Nuremberg<br />

Hall 4 Booth 4-420<br />

The Emsland Group will be exhibiting for<br />

the first time at the Interzoo in Nuremberg<br />

from May 7 to 10. The Emsland Group is an<br />

international company that manufactures<br />

innovative products based on plant-based<br />

raw materials for the pet food processing<br />

industry, among others.<br />

The plant-based ingredients of the<br />

Emsland Group are made from peas<br />

and potatoes. In line with their guiding<br />

principle — “using nature to create”<br />

— the company has developed the<br />

innovative Empet® products for domestic<br />

and commercial animal nutrition. The<br />

components of potatoes and peas are<br />

ideal to support the market trends. These<br />

materials offer the possibility to produce<br />

non-GMO, natural and gluten- and grainfree<br />

products. The portfolio of the Emsland<br />

Group for animal nutrition consists of<br />

proteins, fibers, potato flakes and starches.<br />

Pet food should contain various amino<br />

acids. Although pets are capable<br />

of producing the majority of these<br />

themselves, there are 10 (essential)<br />

amino acids which they cannot generate.<br />

Peas and potatoes are excellent sources<br />

of easily digestible vegetable proteins<br />

and therefore our Empet® protein<br />

ingredients supplement the daily diet.<br />

These ingredients are rich in essential<br />

amino acids such as lysine, methionine,<br />

cysteine, valine, and arginine. Empet® pea<br />

and potato proteins offer many appealing<br />

qualities such as a low ash content as<br />

well as a lack of GMOs, allergens, grains<br />

and gluten. In terms of sustainability,<br />

these plant-based proteins are also more<br />

sustainable than their animal-based<br />

counterparts.<br />

Fibers can play a very important role in a<br />

pet’s diet. Insoluble fibers are responsible<br />

for creating a feeling of fullness without<br />

adding any calories. A higher fiber content<br />

in everyday animal feed increases the<br />

quantity of feed without increasing its<br />

energy content, meaning that the animal<br />

feels full without overeating. Especially<br />

for overweight animals, this can make it<br />

easier to implement a weight loss diet; it<br />

can also improve the feeling of fullness for<br />

animals that are constantly hungry, aiding<br />

in the prevention of obesity. The Emsland<br />

Group’s Empet® E 5 ingredients play what<br />

could be called a “mechanical” role in<br />

the digestive tract. Fibers have proven<br />

effective in relieving the symptoms of<br />

various diarrheal diseases. Fibers even<br />

can be helpful for diseases of the liver and<br />

kidneys. They lower the pH value in the gut<br />

and thus reduce the amount of ammonia<br />

released, which in turn provides relief<br />

to the metabolism through the positive<br />

effect of fibers’ strong ability to absorb<br />

water on diarrheal diseases.<br />

Potato flakes produced from fresh<br />

potatoes are applicable in a wide range<br />

of wet and dry pet food products, for<br />

example in products made by an extrusion<br />

process. In animal nutrition, potato flakes<br />

are used as a cold water functional binder,<br />

dough improver or for optimizing process<br />

viscosity for extrusion.<br />

Meet the Emsland Group at the Interzoo<br />

ingredients made from potatoes<br />

and peas.<br />

Food Ingredients Goes Pet<br />

The Fi Europe exhibition has been running for many years and is a important fixed point in the annual calendar. The world's leading<br />

suppliers attend and meet with the biggest food manufacturers. The focus has been on innovation and ingredients for food and<br />

beverages for human consumption and has both followed and created the trends in recent years. Until now. Ian Healey talked to<br />

Yannick Verry, Brand Manager of the international Food Ingredients Exhibitions organizer Informa Markets about a surprising new<br />

initiative for <strong>2024</strong>.<br />

Simultaneously, a growing number of our visitors are seeking<br />

solutions around pet food manufacturing, whether it is all-inone<br />

contract manufacturing or specific needs, such as a novel<br />

ingredient or new equipment that safeguards nutritional value<br />

during processing. We’re talking about more than 15% of our<br />

visitors who come to the show for pet nutrition, which is amazing<br />

if you think we’ve never promoted the event specifically to the<br />

pet food manufacturing community. It’s a best kept secret until<br />

today, for those who’ve been attending the show in the past few<br />

years.<br />

But this is not surprising because consumers are more demanding<br />

than ever, making continuous innovation in this dynamic market<br />

a necessity. And Fi Europe is at the forefront of F&B innovation -<br />

it’s the place to see and feel the products that we will enjoy on<br />

our plates tomorrow. That’s why the show takes place every year<br />

unlike most of the events in our industry, and it allows pet food<br />

makers to get ahead of their competition.<br />

Yannick Verry, Brand Manager, Food Ingredients Europe &<br />

Americas<br />

Technology & Marketing<br />

Hi Yannick, please introduce yourself and<br />

Informa Markets to our readers.<br />

Hello Ian. I am the Event Director for Food ingredients Europe,<br />

organized by Informa Markets. Fi Europe was launched in 1986<br />

and is the world’s largest event for ingredients and innovation<br />

in the food and beverage industry. Fi Europe is an annual show<br />

and alternates between Paris and Frankfurt, where 1500+<br />

suppliers of food ingredients and manufacturing solutions<br />

present their latest products and innovative solutions to<br />

manufacturers of finished F&B and pet food products.<br />

Technology & Marketing<br />

Why is a food ingredient event now interested<br />

in reaching pet food suppliers?<br />

Prior to my role at Informa Markets, I worked for 12 years in Asia<br />

on one of the largest exhibitions for pet supplies and developed<br />

a strong interest in the sector. After joining Fi Europe last year,<br />

I identified that suppliers of pet food solutions already had a<br />

huge presence at the event: about one third of our exhibitors<br />

are proactively promoting their pet food innovations at the<br />

show. With around 450 companies fitting this profile, this<br />

makes Fi Europe the largest annual gathering of suppliers for<br />

the pet food industry in Europe.<br />

How do you see the pet food market developing<br />

in the next 5 to 10 years? How does this compare<br />

to food for humans?<br />

According to research from Mordor Intelligence, the global pet<br />

food market is growing at 8.54% CAGR over the period <strong>2024</strong>-<br />

2029, faster than F&B – growing at roughly 6% annually over the<br />

same period.<br />

On the one hand, the premiumization of pet food products<br />

alongside the humanization of our furry friends drives the<br />

market value up. And on the other hand, budget constraints<br />

among consumers add to the challenge of manufacturing good<br />

products at reasonable prices. If you add sustainability objectives<br />

or the competition over usage of resources (fatty acids in pet<br />

food vs biofuels for instance), brands will need to rely on the<br />

most innovative suppliers to stay relevant and grow in the next<br />

10 years.<br />

What is the plan to offer a pet food zone and how<br />

would this look?<br />

The Petfood Suppliers Hub will be located at the heart of Fi<br />

Europe near some of our largest exhibitors, offering maximum<br />

exposure to pet food innovations. The area will gather suppliers<br />

of equipment, technology, contract manufacturing and services<br />

alongside the large contingent of ingredients manufacturers and<br />

premix solutions already available at Fi Europe.<br />

It will be a platform for suppliers to share and exchange insights<br />

into the latest market trends and science-backed innovations,<br />

meet the world’s largest pet food manufacturers seeking to stay<br />

ahead of the curve, and newcomers with fresh ideas and different<br />

business models.<br />

Will existing exhibitors have to have two stands?<br />

Exhibitors with an existing stand can enhance the exposure of<br />

their pet food offering at preferential rates through easy-to-setup<br />

“petfood pods” or pre-fitted kickstart packages, while leading the<br />

conversation on innovation and increasing traffic to their main<br />

stand.<br />

Only the best for<br />

our loved ones.<br />

On the other end, new exhibitors and particularly those<br />

offering processing technology, production equipment and<br />

contract manufacturing solutions will benefit from a large<br />

base of highly qualified visitors, with our core audience being<br />

decision makers in procurement & purchasing, engineering &<br />

technical management, R&D, plant management and product<br />

development.<br />

How will this pet food vision benefit from other Fi<br />

shows?<br />

Fi is a global series of exhibitions: from North to South America,<br />

from South-East Asia to China, Japan and Korea, from Europe to<br />

Africa, we have built a global community of tastemakers. This<br />

unparalleled network is an absolute treat for exhibitors at Fi<br />

Europe, the largest and most international of our shows, where<br />

80% of the audience is international.<br />

Is Informa planning an exclusive show for pet<br />

food, or pet supplies in the future?<br />

Given the overlap in challenges and opportunities between F&B<br />

and pet food, we believe that a single event can effectively serve<br />

both industries. But our aim is to provide the best platform that<br />

meets the industry’s ever evolving needs and particularities.<br />

We’re always listening to our community, so anything is possible.<br />

Japanese Pet Food Sector Moves<br />

Towards Premiumization Going<br />

Forward into <strong>2024</strong><br />

by Eugene Gerden<br />

The Japanese pet food sector is steadily<br />

growing these days thanks to the ever<br />

growing demand for high-quality<br />

products and tighthening competition,<br />

despite the general reduction of the<br />

number of pets in local households.<br />

Similar to most of EU markets, the<br />

Japanese pet food market has faced<br />

with a sharp growth of inflation in recent<br />

years, caused by ongoing geopolitical<br />

instability, high prices for energy sources<br />

and the Ukranian war.<br />

The growth of energy prices especially<br />

hit Japan, since the country’s own energy<br />

production is insufficient, which forces<br />

it to meet most of its energy needs by<br />

imports. Since 2022 the cost of such<br />

supplies has significantly increased, which<br />

put a serious pressure on the majority<br />

of segments of industrial production,<br />

including pet food.<br />

The economic problems has led to the<br />

fact that the cost of ownership of pets in<br />

Japan has significantly increased, which<br />

forced many of local households to<br />

substantially cut spending on their pets<br />

Nestle Purina Japan range<br />

and to save on purchase of new ones. In<br />

addition, the growth of production costs<br />

have created serious problems for many<br />

of leading local players.<br />

In fact, the Japanese market has been<br />

traditionally within the sphere of interests<br />

of major global players, many of which<br />

has traditionally increased their presence<br />

in the local market in recent years.<br />

An example is Nestlé Purina PetCare,<br />

which currently remains one of the<br />

leading local players, planning a further<br />

expansion in the Japanese market.<br />

As Kensuke Otani, Business Executive<br />

Officer, Nestlé Purina PetCare, Nestlé Japan<br />

Limited told in an exclusive interview the<br />

Japanese market remains one of the most<br />

prirority for the company, while more<br />

active growth is limited by generally high<br />

rates of inflation in Japan, which have been<br />

observed in recent years. At the same time,<br />

according to him, most of local players pay<br />

big attention for more active launch of<br />

innovative products to the market, which<br />

could provide them additional competitive<br />

advantages over local rivals.<br />

Kensuke Utani, Business Executive Officer<br />

Nestle Purina Petcare Nestle Jap...imited<br />

Kensuke Otani comments:<br />

"The whole category was more focused<br />

on coping with the inflation in last 2 years,<br />

however going into <strong>2024</strong> we see much<br />

more innovations being introduced to<br />

market signaling refocus on category<br />

growth".<br />

As Otani has also added while the number<br />

of pets in Japan is steadily decreasing due<br />

to the cost and other issues, the market<br />

still has big potential for a further growth.<br />

Kensuke Otani continues:<br />

"Despite continuous decline on pet<br />

population, pet food market in Japan<br />

has been growing in value capturing<br />

the humanization trend and through<br />

premiumization. We believe this trend will<br />

continue for next years".<br />

In the meantime, in addition to Nestle<br />

Purina Petcare another global major Mars<br />

has also puts big hopes for the further<br />

expansion of its Japanese business this<br />

year, giving a prirority to the premium<br />

segment of the market.<br />

In recent years the company has extended<br />

its Japanese pet food portfolio, planning<br />

its further expansion in <strong>2024</strong>-2025.<br />

As Yuho Nakamura, an exclusive<br />

spokesman of the company told in an<br />

exclusive interview the company has<br />

extended line for Kalkan Pouch/No<br />

colorants or coloring agents and added 3<br />

products (1 for kitten, 2 for senior cats) in<br />

February of the current year.<br />

The company puts big hopes on more<br />

active promotion of its products among<br />

Japanese customers this year, paying<br />

a particular focus to natural, organic<br />

products, such as Nutro, a natural pet<br />

food, and Greenies, which provides health<br />

value through treats.<br />

As Nakamura believes the current trends<br />

will continue to be observed in the market<br />

throughout the entire <strong>2024</strong>.<br />

Yuho Nakamura continues:<br />

"Similar to recent market trends, we<br />

assume that the number of dogs will<br />

decline and that small and ultra-small<br />

dogs will become the norm, resulting in<br />

lower volume, but that demand for highvalue-added<br />

pet food will remain strong<br />

as pets become a part of the family".<br />

According to experts of the Japanese Pet<br />

Food Association, the Japanese pet food<br />

market is characterized by high level of<br />

maturity and generally low growth rates,<br />

being varied in the range of 2-4% in value<br />

terms.<br />

common pets in Japan - kept is either<br />

flat or on the decline, while most of<br />

local pet food companies are focusing<br />

on developing high-priced products<br />

with enhanced functionality and quality.<br />

Meanwhile, the average lifespan of pets<br />

was 14.62 years for dogs and 15.79 years<br />

for cats.<br />

In response to the aging of pets, the<br />

demand for pet food is growing with the<br />

increase of production high value-added<br />

products for seniors, such as those for 13<br />

years and older and those for 15 years<br />

and older. At the same time, the market<br />

for therapeutic foods and supplements<br />

with nutritional balance is also expanding.<br />

Some manufacturers have started selling<br />

treats for cats that are gender-specific.<br />

In the snack category, sales of products<br />

based on the concept of dental care are<br />

alsdo increasing.<br />

According to producers and experts of the<br />

Japanese Pet Food Association, currently<br />

best-selling pet foods are shifting to<br />

higher price ranges, while more and<br />

more local manufacturers are focusing<br />

Mars Pet Nutrition range in Japan<br />

on developing products with increased<br />

added value. At the same time the number<br />

of health-conscious owners who are<br />

concerned about their pets' health, and<br />

pets' preference for gourmet food is also<br />

growing. It is expected that the segment of<br />

premium foods with high prices and high<br />

profit margins will remain one of the major<br />

drivers for growth for the entire Japanese<br />

pet food market in the future. Finally, the<br />

segment of super premium foods that<br />

emphasize further differentiation such as<br />

additive-free and non-allergenic foods will<br />

be further growing at higher rates, that<br />

the average growth rates of the market.<br />

In general, according to experts of the<br />

Association, the demand for pet food in<br />

Japan will continue to grow, as many of<br />

local companies launched new products<br />

with health-conscious features such as<br />

low-salt content. The list of major local<br />

players includes Unicharm, Mars Japan<br />

Limited, Nestlé Japan, and Nippon Hills<br />

Colgate. Unicharm, the biggest national<br />

pet food producer, is famous for its<br />

brands such as "Gin no Spoon" and "Ainu<br />

Genki", which are very popular among<br />

the Japanese customers being currently<br />

among the most renowned brands.<br />

Enhancing Pet Food Safety with<br />

Cutting-Edge Magnetic Separation<br />

Technologies<br />

by Chris Ramsdell, Eriez Product Manager – Separation<br />

Grate In Housing-109<br />

Pet owners worldwide consider their furry<br />

companions integral members of the<br />

family, emphasizing the importance of<br />

ensuring the safety and quality of pet food.<br />

In alignment with the rigorous standards<br />

applied to human food production, leading<br />

pet food manufacturers globally turn to<br />

Eriez magnetic separation equipment to<br />

guarantee their products are free from<br />

metal contamination, a potential hazard to<br />

pets.<br />

Metallic impurities jeopardize the integrity<br />

of pet food, necessitating the rejection of<br />

affected batches. These contaminants can<br />

originate from various sources, including<br />

transportation vehicles used for product<br />

delivery, such as tanker trucks or railcars.<br />

Additionally, internal contamination<br />

may occur during material processing,<br />

grinding, or general abrasion within<br />

the manufacturing plant. Fortunately,<br />

the application of magnetic separation<br />

equipment proves instrumental in<br />

mitigating or eliminating ferrous metal<br />

contamination issues.<br />

Cutting-edge magnetic separators,<br />

available in diverse designs, effectively<br />

remove ferrous materials such as nails, rust,<br />

scale, hardware, and other contaminants<br />

from both dry and liquid pet food products.<br />

This article delves into the application<br />

of magnetic separation equipment in<br />

pet food facilities, highlighting its role in<br />

producing a safer, higher-quality pet food<br />

product.<br />

Liquid Line Magnetic Separators<br />

For low-viscosity ingredients that flow<br />

freely, Eriez recommends Model B-Traps.<br />

These separators utilize a set of cantilevered<br />

rare earth tube magnets inserted into<br />

a cast stainless steel sump body. As the<br />

product weaves through the magnetic<br />

tubes, ferrous contaminants attach to the<br />

tubes. The powerful rare earth magnetic<br />

circuit holds onto these materials until the<br />

unit is cleaned.<br />

For high-viscosity products like meat<br />

emulsions and final wet food products,<br />

the Eriez Model U-Trap is the preferred<br />

magnetic separator. The high-strength<br />

rare earth plate magnet is mounted to the<br />

bottom of a cast housing where it does<br />

not impede product flow. The U-Shape<br />

housing construction forces the product<br />

to come in close contact with the plate<br />

magnet which attracts and holds any<br />

ferrous contaminants until an operator<br />

cleans it off.<br />

Simmons Pet Food has five pet food<br />

production facilities in North America<br />

that produce more than 3,500 unique<br />

SKUs. At their wet pet food facility in<br />

Mississauga, Ontario, Simmons installed<br />

several U-Traps to serve as a quality check<br />

for final wet food products. These units are<br />

installed downstream of a mixing tank and<br />

emulsifier, immediately upstream of their<br />

metal detectors. (See "Protecting Pets with<br />

Magnetic Separation Technologies" - White<br />

Paper FA-57 Eriez Model U Magnetic Traps<br />

Eriez Model B Magnetic Traps on 4" lines.)<br />

With this equipment arrangement, metal<br />

detectors focus on identifying any nonmagnetic<br />

metals that may be present in<br />

the product. The U-Traps remove ferrous<br />

metal contaminants upstream of the metal<br />

detectors, reducing the amount of product<br />

rejected by the metal detectors. According<br />

to Maintenance Manager Kenn Jones, these<br />

traps reliably recover ferrous fines 2-3 mm<br />

in size and have helped Simmons increase<br />

total product yield while maintaining high<br />

quality standards.<br />

Dry Bulk Ingredients<br />

For dry ingredient applications with higher<br />

throughput requirements, Eriez suggests<br />

incorporating magnetic drums-inhousing<br />

to remove ferrous contaminants.<br />

Drum magnets are commonly installed<br />

to process pet food ingredients like<br />

corn, grains, chicken/turkey meals, dry<br />

vegetables and beet pulp. These units<br />

are typically placed near the beginning<br />

of the process where most of these bulk<br />

ingredients are unloaded from rail cars and<br />

trucks before further processing. Magnetic<br />

drums can also be installed at the end of<br />

the process to provide a quality check on<br />

dry bulk kibble.<br />

Drum magnets are self-cleaning magnet<br />

assemblies that continuously remove<br />

ferrous contaminants from a product flow.<br />

The magnet assembly is enclosed within a<br />

stainless-steel drum and fixed in position.<br />

The drum shell rotates around the magnet,<br />

conveying the material through the<br />

magnetic field. The clean (non-magnetic)<br />

material cascades off the drum face on<br />

its normal trajectory while the magnetic<br />

material is drawn around the drum and<br />

discharged at the bottom. Magnetic drums<br />

designed with ceramic magnet circuits are<br />

ideal for removing relatively large ferrous<br />

objects from a dry product flow, while<br />

rare earth magnetic circuits are utilized<br />

to remove very fine or weakly magnetic<br />

contamination.<br />

For lower throughput applications,<br />

Eriez recommends magnetic grates-inhousing.<br />

These units, usually installed<br />

in vertical chutes, can be supplied with<br />

one or multiple rows of magnetic grates<br />

with staggered permanent magnetic<br />

tubes to capture ferrous contaminants.<br />

Dry ingredients entering the housing are<br />

forced to weave through the staggered<br />

magnetic tubes, effectively removing<br />

everything from hardware to metal<br />

shavings. Eriez Rare Earth Magnetic Grates-<br />

In-Housing can remove contaminants<br />

as small as fine ferrous dust and scale.<br />

They are suitable for processing fine, freeflowing<br />

ingredients such as milled grains<br />

and pet food powders.<br />

The simplest versions incorporate a singlelayer<br />

magnetic grid and are used inside a<br />

hopper so that raw materials must pass<br />

through the grates as material feeds from<br />

the hopper. Multiple row units improve<br />

separation effectiveness. Grate-housing<br />

designs may include a standard grate<br />

that can be removed from the housing for<br />

manual cleaning. An easy-to-clean grate<br />

design enables push/pull operation to strip<br />

accumulated tramp metal from the grates<br />

without physically handling the magnet.<br />

Eriez also offers an Automatic Easy-To-<br />

Clean model which uses a set of pneumatic<br />

cylinders to automatically discharge tramp<br />

metal from the magnetic grates with the<br />

push of a button or timer control.<br />

About Eriez®<br />

Established in 1942, Eriez is a global<br />

leader in separation technologies. Our<br />

commitment to innovation has positioned<br />

us as a driving market force in several key<br />

technology areas, including magnetic<br />

separation, flotation, metal detection<br />

and material handling equipment. The<br />

company’s 900+ employees are dedicated<br />

Pneumatic Line Magnetic<br />

Separators<br />

Many dry ingredients are brought into<br />

processing facilities from trucks or railcars<br />

via air conveyance. This is where the Eriez<br />

Model RF (Radial Field) Cartridge comes<br />

in. When a truck or train car pulls into the<br />

material unloading area and pneumatic<br />

lines are used to transfer the incoming<br />

material into the plant, Eriez RF Cartridges<br />

are often installed on the other side of<br />

building/wall to safeguard against metal<br />

entering the plant.<br />

As material enters<br />

the RF Cartridge<br />

inlet, it contacts<br />

a fixed nose<br />

cone, forcing the<br />

material to the<br />

outside walls of<br />

the housing. The<br />

material then<br />

cascades around<br />

a cylindrical magnetic<br />

element<br />

and ferrous contaminants<br />

attract<br />

and attach to the<br />

magnet’s collection<br />

points.<br />

For cleaning, an<br />

operator can<br />

easily remove a<br />

magnetic element<br />

and wipe it off<br />

with a gloved<br />

hand or rag. This<br />

unit is designed<br />

for installation in<br />

3" - 6" lines (25psi<br />

Batching Systems in the Pet Food<br />

Industry: Precision and Efficiency<br />

The world of pet food production requires<br />

maximum precision in the dosing and<br />

packaging of ingredients. Charging<br />

systems play a decisive role in this.<br />

Batching systems are indispensable in<br />

the pet food industry. These industrial<br />

systems enable ingredients to be dosed,<br />

transferred and weighed in precisely<br />

defined quantities. But their importance<br />

goes beyond mere dosing.<br />

They are used to mix and, if necessary,<br />

package ingredients in precisely measured<br />

quantities. This not only ensures<br />

compliance with recipes, but also the<br />

quality and consistency of the end<br />

products.<br />

Pet food production often requires a wide<br />

range of ingredients, including meat,<br />

grains, vitamins and minerals. Batching<br />

systems ensure that these ingredients are<br />

mixed in the right quantities and ratios to<br />

meet the nutritional requirements of pets.<br />

The core functions of batching<br />

systems<br />

Batching systems are versatile and provide<br />

a number of basic functions:<br />

1. Accurate dosing: the main task of a<br />

batching system is to accurately dose<br />

ingredients according to specified recipes<br />

or formulas. This is crucial to ensure the<br />

quality and consistency of the pet food<br />

products produced.<br />

2. Safe decanting: after dispensing,<br />

materials are safely transferred into containers<br />

or packaging. This ensures not<br />

only hygiene, but also the prevention of<br />

waste.<br />

3. Weighing: the integrated weighing<br />

systems ensure that the correct amount<br />

of materials enters the packaging.<br />

This is essential to ensure compliance<br />

with quality standards and regulatory<br />

requirements.<br />

Additional functions for<br />

efficiency and flexibility<br />

Modern batching systems also offer a<br />

wide range of additional functions that<br />

further optimize the production process:<br />

1. Process control and monitoring: the<br />

plants are equipped with advanced control<br />

systems that can monitor and control<br />

the production process in real time. This<br />

ensures continuous quality assurance.<br />

2. Recipe software: The integration of<br />

recipe software allows different mixes<br />

and batches to be adjusted quickly and<br />

precisely, depending on the requirements<br />

of the pet food product.<br />

3. Adaptability: modern charging systems<br />

are able to adapt to different container<br />

sizes. This increases flexibility and<br />

efficiency in production.<br />

4. Easy cleaning: hygiene is critical in the<br />

pet food industry. Charging systems are<br />

designed to be easy to clean to avoid<br />

contamination.<br />

Conclusion<br />

Batching systems are indispensable<br />

tools in the pet food industry, enabling<br />

precise dosing, safe transfer and accurate<br />

weighing of ingredients. With additional<br />

features for process control, adaptability<br />

and easy cleaning, they contribute<br />

to efficiency and quality assurance in<br />

production. In an industry that focuses<br />

on the health and well-being of pets,<br />

batching systems are an essential part of<br />

the production chain.<br />

These multiple features and benefits of a<br />

batching system from Mohn were seen at<br />

Anuga FoodTec in Cologne, Germany, last<br />

on world-class inspection equipment<br />

including a Mettler-Toledo Safeline X33<br />

x-ray inspection system, installed at their<br />

“Riverstone” facility in Westminster, MD.<br />

“We completed a big, facility-wide<br />

renovation and updated our lines with<br />

the latest technology. It was our sales<br />

rep, Dick DeNenno at Reliant Packaging<br />

Machinery, who encouraged us to go<br />

with x-ray inspection. X-ray systems<br />

identify and remove stones, shells, glass,<br />

rubber and other foreign bodies, in<br />

addition to detecting metal,” said Kelly<br />

Raiser, General Manager and co-owner<br />

of Earth Animal’s Riverstone facility.<br />

“Our pet foods are made with real, fresh<br />

ingredients, which means that natural<br />

foreign materials like pebbles are not<br />

uncommon. With our X33, we can be<br />

sure no foreign bodies make their way<br />

into the final product – we’re protecting<br />

our customers and their pets, as well as<br />

our brand.”<br />

“Our new X33 x-ray system helped us<br />

see that our primary vulnerability comes<br />

from incoming raw ingredients, not from<br />

any issues inside our plant. Knowing this,<br />

we went to our ingredient suppliers and<br />

asked them to put in more safeguards on<br />

their side,” said Nick Stalder, Production<br />

Manager at Riverstone. “Now we can<br />

hold our suppliers accountable if it<br />

looks like foreign material came in with<br />

their raw product. Honestly, our X33 has<br />

already paid for itself with that process<br />

A Case Study on Eilersen<br />

Capacitive Load Cells<br />

In the highly competitive and industrially<br />

demanding meat processing industry,<br />

reliability and cost efficiency are crucial<br />

factors for operational success, whether<br />

competing locally or globally.<br />

Oestergaard A/S, a leading global meat<br />

rendering solutions market player, relies<br />

on Eilersen digital capacitive load cells for<br />

precise and reliable weight measurement<br />

— a critical measurement in meat<br />

rendering solutions and particularly<br />

relevant for the pet food industry.<br />

40<br />

Technology & Marketing


Challenging environments<br />

drive a need for reliable<br />

weighing solutions<br />

In some industries, the working<br />

environment can be exceptionally<br />

demanding, and the meat rendering<br />

industry is a prime example of this. Anders<br />

Juul, who has been a part of this industry<br />

for more than two decades, has witnessed<br />

firsthand how the technology used in<br />

different load cells can impact day-to-day<br />

operations.<br />

Operating in meat production facilities<br />

can be challenging, with the pervasive<br />

presence of ammonia fumes and animal<br />

fats on most surfaces. These conditions<br />

create a particularly harsh environment<br />

for any load cell system and cause load<br />

cell cables to disintegrate after a few years.<br />

This scenario poses a significant challenge<br />

for weighing solutions, emphasizing the<br />

need for accurate and robust equipment<br />

to endure these tough conditions.<br />

Typically, a meat rendering machine<br />

from Oestergaard A/S is installed on four<br />

compression load cells and must operate<br />

under the following conditions:<br />

• A total working weight of up to 200 tons<br />

• Internal working temperatures ranging<br />

from 40°C to 180°C<br />

• Horizontal expansion of the machine, of<br />

up to 20 mm<br />

• Welding on machines during installation<br />

often occurs<br />

The Eilersen capacitive load cells have<br />

proven remarkably reliable over the years,<br />

with several beneficial features compared<br />

to traditional strain gauge load cells.<br />

For machines using Eilersen digital load<br />

cells, it is possible to monitor the load<br />

distribution on each load cell which is<br />

beneficial to ensure correct installation.<br />

The individual Eilersen digital load cells<br />

even send an error code if maintenance<br />

should be required for fast and easy<br />

trouble-shooting. But apart from features,<br />

it is the durability of Eilersen load cells that<br />

seems to impress customers experienced<br />

in weighing technology. Even though<br />

it is not recommended, employees at<br />

Oestergaard A/S often need to weld on<br />

or close to machines installed on load<br />

cells. Anders Juul, Project Manager at<br />

Oestergaard A/S explains:<br />

“Often, welding is required during<br />

the installation process, which often<br />

damages a strain gauge load cell, causing<br />

expensive delays as we need to order<br />

express delivery of replacement load cells<br />

to customer sites. However, we have not<br />

experienced damaging the Eilersen load<br />

cells since we started using them many<br />

years ago, even when welding on the<br />

machines.”<br />

Eilersen load cells installed a decade or<br />

more ago — some even 30 years back<br />

— have been operating with the same<br />

accuracy and reliability as when they<br />

were new, despite being exposed to high<br />

horizontal loads and frequent overloads.<br />

Reducing downtime using<br />

digital capacitive load cells<br />

The possibility of replacing load cell cable<br />

on Eilersen load cells without needing<br />

to change or recalibrate the weighing<br />

system makes them optimal for harsh<br />

meat rendering environments, where<br />

load cell cables often have a lifespan of<br />

only four to six years. These features, along<br />

with their consistent performance over<br />

time, not only showcase the exceptional<br />

longevity of Eilersen load cells but<br />

also their dependability, especially in<br />

challenging environments like the meat<br />

rendering industry. Anders Juul highlights<br />

the advantages of being able to replace<br />

load cell cables on-site without the need<br />

for recalibration of the system. He shares<br />

his experience with Eilersen capacitive<br />

load cells, saying:<br />

“We encounter no issues when using<br />

Eilersen load cells. Eilersen provides a<br />

reliable weighing system that’s not only a<br />

breeze for us to work with but also instills<br />

confidence in our customers who rely on<br />

the load cells in day-to-day operations.<br />

From planning to installation, the process<br />

is always smooth sailing. If something<br />

goes wrong after commissioning, and we<br />

need to replace a load cell cable, we can<br />

easily do so without replacing the entire<br />

load cell.”<br />

Expertise as a Service<br />

In the meat rendering industry, everything<br />

must go according to plan — always. But<br />

sometimes, unforeseen issues arise, and<br />

quick action and support is necessary.<br />

Anders is confident that there won’t ever<br />

be such an incident when using Eilersen.<br />

However, when Oestergaard A/S needs<br />

any assistance, expertise and first-class<br />

support is always available as a service.<br />

“If we ever need help, we just pick up<br />

the phone and call Eilersen. I’m only one<br />

phone call away from talking to someone<br />

who understands the situation and can<br />

help solve any issue. Having access to<br />

such expertise is critical for my role and<br />

our clients.”<br />

Eilersen Capacitive Load Cells<br />

While strain gauge load cells measure<br />

the change of resistance and strain of the<br />

load cell body, the capacitive technology<br />

instead measures the change of distance<br />

between the load cell body and an<br />

internal ceramic sensor. This patented<br />

contactless measurement principle makes<br />

the capacitive weighing technology able<br />

to tolerate extremely high overloads,<br />

side loads, torsional forces, and welding<br />

voltages.<br />

The capacitive load cells were invented<br />

at Eilersen and have been thoroughly<br />

tested and proven over 50 years. Eilersen<br />

load cells are known for being robust,<br />

accurate, and reliable. They are used<br />

in various industrial applications and<br />

industries ranging from offshore, logistics<br />

to the biopharma industry. The load cells<br />

are produced in stainless steel, are laser<br />

welded, and are an obvious choice for<br />

industries due to their hygienic design<br />

(IP68), digital output, and high overload<br />

tolerance.<br />

About Eilersen Electric A/S<br />

Since its foundation in 1969, Eilersen<br />

Electric A/S has been dedicated to<br />

developing, manufacturing, and<br />

supplying high-quality, robust load<br />

cells based on capacitive technology for<br />

Innovative Packaging with Easy-<br />

Opening Assistance for Sausage<br />

Snacks and Small Portions<br />

The TSCA 120 seal-clip machine from Poly-clip System is a highly efficient solution for snack packaging of<br />

sausage snacks or small portions. What makes it stand out? The specially developed film solution is used<br />

to create a PVDC-free packaging system with convenient tear assistance. This results in modern, attractive,<br />

and practical snack packaging that completely dispenses with components which could be harmful to the<br />

environment and consumer health.<br />

Healthy snacking is a growing trend.<br />

Nutritionists confirm that consumers<br />

increasingly value high-quality snacks<br />

with natural ingredients. Food producers<br />

are adapting their product portfolios to<br />

meet this demand. This includes suitable<br />

packaging that offers consumers a<br />

high level of convenience. The seal-clip<br />

machine TSCA 120 from Poly-clip System<br />

is an excellent solution for the production<br />

of innovative snack packaging of sausage<br />

products and other small portions. A<br />

major advantage of this packaging<br />

solution is that unlike conventional<br />

sausage-snack packaging, the clip<br />

packaging (clip-pak®) can be made from<br />

PVDC-free materials, while still delivering<br />

maximum performance.<br />

"Excellence in Clipping" with<br />

the seal-clip machine TSCA 120<br />

The seal-clip machine TSCA 120 reliably<br />

seals a flat film into a fillable tube and<br />

then closes the filled packaging with<br />

bacteria-tight R-ID clips. Using an<br />

innovative film solution, the machine<br />

produces highly cost-effective packaging<br />

with tear assistance, suitable,<br />

for example, for sausage snacks. It<br />

processes up to 3,300 meters of flat film<br />

in one go, achieving up to 4 hours of<br />

runtime without the need for operator<br />

intervention. During this process, clip<br />

and film consumption are automatically<br />

monitored. All parameters are stored in<br />

the recipe management system, thus<br />

ensuring maximum process reliability.<br />

In addition, this robust machine is<br />

characterized by exceptional reliability:<br />

it features consumption-oriented centralized<br />

lubrication which reduces<br />

wear and tear. This leads to reduced<br />

maintenance interventions and less<br />

downtime, ultimately extending the<br />

machine's lifespan.<br />

Easy-Opening Solution: PVDCfree<br />

sausage casing for snack<br />

packaging with tear assistance<br />

The powerful seal-clip machine TSCA<br />

120 used in conjunction with the<br />

corresponding film produces modern<br />

snack packaging with an innovative<br />

Easy-Opening Solution. Heat-sealable<br />

composite films, consisting of a PE<br />

(Polyethylene) outer layer and a PA<br />

(Polyamide) inner layer, are utilized.<br />

The opening mechanism is based on<br />

defined lateral incisions in the flat film,<br />

prepared during the production of the<br />

film. Additionally, the predefined opening<br />

is coated with an anti-sealant to create a<br />

tear tab during further processing. The<br />

seal-clip machine TSCA 120 processes<br />

the flat film into a tube, which is sealed<br />

longitudinally by heat sealing. During<br />

this process, the integrated tab, due to<br />

the anti-sealant, does not bond with<br />

the underlying film, thus preparing the<br />

opening aid. After filling, the tube is<br />

securely sealed in the integrated clip unit<br />

using bacteria-tight R-ID clips in a doubleclip<br />

process. To consume the snack, the<br />

packaging can later be conveniently<br />

pulled open across the seal seam by using<br />

the tear tab.<br />

"With this innovative packaging for the<br />

continuously growing snack segment,<br />

we offer our customers an attractive<br />

and eye-catching solution that meets all<br />

requirements for modern convenience<br />

Clean Machine Technology for<br />

Outstanding Pet Food Quality<br />

K+G Wetter with First Ever Appearance at Interzoo in Nuremberg<br />

Interzoo <strong>2024</strong><br />

May 7-10<br />

Nuremberg<br />

Photos: K+G Wetter<br />

At the heart of VetConcept’s wet feed production<br />

are two AW 280s from K+G Wetter. The industrial<br />

automatic grinders with a cutting set diameter of<br />

280 mm process frozen meat and raw materials<br />

containing bones – perfect for pet food.<br />

Grinders, mixer grinders and cutters with<br />

the right twist for pet food: For the first<br />

time, K+G Wetter will have its own stand<br />

at Interzoo in Nuremberg to show what<br />

sophisticated food processing machines<br />

can do for pet food production - in terms<br />

of quality and hygiene, versatility and<br />

efficiency.<br />

In Hall 4A, Stand 412, the meat processing<br />

machine manufacturer from Hesse will be<br />

presenting a selection of medium-sized<br />

machines: "This will give customers from<br />

the pet food sector an idea of the features<br />

we offer in machines of all sizes," says Volker<br />

Schlosser, Sales Manager International at<br />

K+G Wetter. "We are always open to our<br />

customers' requirements, consider all the<br />

important issues in meat processing and<br />

use them to develop ingenious grinder<br />

and cutter technology."<br />

Accordingly, with these machines<br />

everything runs smoothly in the growing<br />

global animal feed market - more and<br />

more producers are relying on grinders<br />

and bowl cutters from K+G Wetter, both<br />

smaller producers and large industrial<br />

customers.<br />

VetConcept: two K+G Wetter<br />

grinders for special animal feed<br />

One of these satisfied customers is<br />

VetConcept. The German specialty food<br />

manufacturer produces dietetic food<br />

for dogs and cats with certain health<br />

problems, or also tailored to age, activity<br />

and breed.<br />

Master butcher Arthur Schäfer, as plant<br />

manager, had two automatic grinders<br />

from K+G Wetter at the top of his wish list<br />

when planning the new wet food plant.<br />

"At my training company we enjoyed<br />

super cooperation, so it didn’t occur to<br />

me to choose any other option other<br />

than K+G Wetter as the manufacturer.<br />

The grinders are good, they work really<br />

well," says Arthur Schäfer about the two<br />

AW 280 industrial grinders. "For our many<br />

products and the high tonnage per hour,<br />

it was crucial that we can do everything<br />

from frozen meat to fresh produce with<br />

these machines."<br />

Raw materials containing bones? No<br />

problem for the industrial grinders either:<br />

"Bones are a natural source of calcium<br />

for our feed varieties. It's the same as<br />

the animal would eat in nature," reports<br />

Arthur Schäfer. "The grinder used must<br />

have the necessary power and robustness<br />

to crush the extremely hard material."<br />

Hygiene issues neatly resolved<br />

K+G Wetter has also cleanly solved<br />

all hygiene issues. The challenge at<br />

VetConcept: "As we produce special<br />

food, we have to have very clear batch<br />

separation. For example, we produce<br />

monoprotein varieties such as horse,<br />

kangaroo or goat. When changing<br />

batches, everything on the machine has<br />

to be super clean to protect sensitive and<br />

allergic animals from unwanted proteins,"<br />

explains plant manager Schäfer. "So we<br />

also have to clean the machines quickly<br />

and easily between batches. This works<br />

very well with<br />

the grinders<br />

from K+G Wetter."<br />

Hall 4A Booth 412<br />

A special feature of the K+G Wetter<br />

grinders is the cleaning chamber, which<br />

eliminates a typical hygiene risk with<br />

grinders: The grinding process generates<br />

very high pressure. Liquid product<br />

components or even small product<br />

particles can be pressed through the<br />

seals into the machine interior against<br />

the cutting set and form deposits there.<br />

These particles are collected in the<br />

cleaning chamber and, are rinsed out and<br />

do not provide a breeding ground for<br />

germs. "We have converted the cleaning<br />

chamber so that the connections fit with<br />

our CIP system, foam goes in there, warm<br />

water, that works," says Arthur Schäfer<br />

about the customization for VetConcept<br />

at the K+G Wetter grinders. The additional<br />

time required for cleaning is negligible,<br />

with maximum hygiene effect.<br />

Technology for thousands of<br />

tons<br />

Industrial machines such as the automatic<br />

grinders from K+G Wetter are a major<br />

investment in which sustainability plays a<br />

major role; after all, they are designed to<br />

function for many years and process tens<br />

of thousands of tons of raw materials.<br />

"The animal feed market is growing<br />

enormously, between 15 and 25 percent<br />

per year. As a producer, you have to<br />

keep up with this, of course," says Arthur<br />

Schäfer. To ensure that the machines also<br />

keep up with this pace in the long term,<br />
