Editorial

This year, secpho’s motto has been refined to attain its maximum impact

and it calls for us to Collaborate to innovate. Never before have

these two verbs held more meaning, with this edition of Light! uniting

the complementarity of two key sectors: food and photonics.

The figures reveal that the food and beverages industry has reaffirmed

itself as the leading industrial sector in Spain, which means that the

country’s competitiveness and economy depend to a large extent on

the success of this sector. In this context, and in order to continue increasing

production, rise in the rankings of EU exporters and increase

the number of direct jobs, the food industry must address its main

technological challenges by safeguarding three intrinsic concepts:

quality, safety and productivity. In this endeavour, light technologies

are being deployed so as to become an indispensable ally that offers

the most innovative solutions.

In this third issue of Light! it becomes clear how light control allows us

to determine the quality and composition of food, monitor the entire

production process in an efficient way, increase crop yields, analyse

the health of fish populations, improve packaging and bottling, etc. and

all in a spirit that is focused on the search for continuous innovation.

Leading national experts in photonics gather once again in Light!,

demonstrating their top talents and emphasising their firm commitment

towards collaborating to innovate. Will you join us?

Digitising

the food industry

Flexible production that is efficient and with the capacity

for customisation. That is the proposed concept

of Industry 4.0 that is here to stay and is leading to the

creation of an increasingly interconnected industrial

environment.

This proposal not only involves a technological change,

but also a paradigm in which processes and technologies

must go hand in hand. In fact, a technological

change is meaningless if it is not part of an evolution of

the production model towards short cycles thanks to

Lean tools, which enable the optimisation of processes

and the application of continuous improvement, as

well as reducing unproductive times and improving

the availability of equipment.

From a technological point of view, it is about equipping

the machines with new technologies, both hardware

and software, that possess a certain degree of

intelligence necessary to make the processes more

flexible and decision-making quicker and more optimal.

This key technology includes advanced sensorisation,

laser systems and big data.

Within this technological field, photonic technologies

are understood to be tools that can help us in two

main objectives: to increase production and improve

food safety.

As regards increased production, technologies such as

infrared spectroscopy or hyperspectral imaging enable

aspects such as nutrient content, the ripening point or

the detection of chemical products and contaminants,

among others, to be monitored.

Ensuring that food and beverages are safe for consumption

is another way in which photonics plays an

important role in terms of health. Recent innovations

in hyperspectral imaging sensors have enabled food

safety and food quality inspections to be improved.

The present and future lie in the application of these

technologies on direct monitoring on the processing

line and in real time, as well as in the development of

food packaging that enables better food preservation

through the use of tools such as lasers.

FRIT RAVICH

OVERVIEW

INDUSTRY 4.0 AT FRIT RAVICH

At Frit Ravich, as a benchmark company in the food

and distribution sector, we are committed to the

cross-disciplinary implementation of the Industry 4.0

concept throughout our production process. In fact, it

is a key aspect in the company’s strategic plan that is

deployed in three areas in this field:

•Flexibility and scalability.

•Quality improvement

•Improvement of costs and productivity

FLEXIBILITY AND SCALABILITY

Frit Ravich’s production system allows us to be more

flexible and scalable, while adopting a high level of innovation

and customisation of products demanded by

customers and/or consumers.

The company’s main objective is to guide the entire

value chain towards the customer, being mindful that

the consumer profile is that of a permanently connected

person with constant access to information, and

who becomes part of the creation process itself. This

accessibility to information, achieved thanks to technology,

means that food products are linked to values

such as transparency, health and customisation.

QUALITY IMPROVEMENT

We currently have machinery that incorporates sensors

aimed at controlling aspects such as colour or

weight and an X-ray detector that helps us monitor the

quality of products at all times.

IMPROVING COSTS AND PRODUCTIVITY

At Frit Ravich we have an automated production system

through the use of autonomous collaborative robots

with high flexibility. Thanks to these, new products

can be created in a very short time, formats can

be changed instantly and they ensure interaction with

operators.

This system is complemented by our MES (Manufacturing

Execution System) software, which allows us to

increase the production plant’s efficiency. It is thanks

to its connectivity with all the teams that the best decisions

can be made at any time.

SECPHO

OVERVIEW

Photonic solutions

for the food industry

Photonics has become such a broad and diverse science

and set of technologies that we find it in practically

all sectors of our economy, such as beauty, safety,

and transport, among others. In Spain, one of the fundamental

pillars of the economy is the food industry

which, being able to provide higher level products, has

undergone several revolutions throughout history:

from the development of techniques for better preservation

of food to its packaging, through improvements

in quality controls, or systems that determine the optimum

time for harvesting, to name but a few examples.

The next revolution in the food industry has been

brewing for a few years, when photonics was incorporated

as a key element at all levels, and nowadays the

future of this sector cannot be imagined without technologies

based on light. Light control allows us to gain

access to a material’s diverse physical properties in a

precise, rapid and continuous way, which makes it an

ideal instrument for measuring the quality and composition

of food. In addition, monitoring elements such

as cameras, hyperspectral, thermal or spatial sensors,

including their combination with new technologies

such as artificial vision or deep learning, are becoming

practically essential for food production and improving

food safety. The underlying concept with all these

advances is to design efficient systems that help us to

monitor both the quality of the product and its production

in an objective and quantitative way.

One of the earlier technologies that has emerged as

a cornerstone in this new revolution in the food industry

is hyperspectral sensors. While the human

eye is able to see a colour image in three bands (blue,

green and red) ranging from around 400 to 700 nanometres,

hyperspectral sensors are capable of dividing

the spectrum into many more bands and using a

wider spectrum. As each material has its own spectral

fingerprint, this technology can distinguish between

different foods, know when a food is off or when it

contains traces of elements that are harmful to health.

For example, in the field of agriculture, hyperspectral

sensors provide insight into the water levels of a plant

or if it has a type of parasite that requires a specific

treatment, while serving to determine soil health, the

point of ripeness of fruit and vegetables, and to detect

LIGHT! by by SECPhO secpho 9


chemicals and contaminants. This technology is also

being used in production chains for the detection of

foreign bodies.

The automation of processes is something that is also

being applied to the food industry at different levels,

such as processing and safety, packaging and livestock

monitoring. In this sense, artificial vision is playing a

very important role thanks to its ability to determine

the colour, shape, or size of the products through camera

systems and image processing software. In recent

years, 3D time-of-flight cameras, or ToF cameras, have

also been introduced into the sector. This technology

is able to measure the time elapsed between the emission

and reception of a pulse of light when it is reflected

by each point of the environment, thus obtaining an

image with information about the depth of each object

that forms it. This is particularly interesting for the

storage, organisation and smart selection of products

in production chains. Artificial intelligence, specifically

deep learning, is also being used by the industry for

artificial vision. The idea behind deep learning is to use

large amounts of data to train algorithms capable of

making decisions or identifying objects based on certain

parameters. In recent years, deep learning, which

is having a significant global impact on many areas of

our life, has been replacing a great range of image processing

software. This technology has been serving the

food industry for crop monitoring by combining drones

with various sensors and traditional and hyperspectral

or ToF cameras. A good example of this is a pioneering

technology developed by AINIA, in which a drone with

a hyperspectral camera is able to identify the needs of

each plant.

The interaction of infrared light with materials is particularly

useful because long wavelengths have a

deeper penetration depth, while also allowing the use

of near infrared (NIR) spectroscopy. The fundamental

idea of spectroscopy is knowing which parts of the

spectrum are absorbed and reflected by the material

analysed, which allows us to know its precise chemical

composition and measure its quality at high speed.

This has direct applications in the food industry, where

NIR spectroscopy is being used nowadays to measure

the fat content of milk, alcohol content or oxidation of

wine, ripeness of a fruit or adulteration of cocoa, even

once packaged.

Another key element in the food industry is the ability

to control and monitor the temperature in each step

during the processing and packaging of food. Thermography

is a technique that enables the measurement of

infrared radiation in a material, which gives information

about its temperature regardless of the lighting

conditions. This independence from lighting condi-

10 LIGHT! by secpho


tions is particularly interesting, because it enables its

integration with other measurement systems at other

wavelengths. The higher the temperature, the greater

the amount of thermal radiation, so small changes in

the temperature of a material can be measured simply

by measuring the levels of infrared light it emits. Thermography

has an impact on the food industry in different

stages: from controlling the cooking point of food,

guaranteeing controls on sealing, through to the maintenance

of the cold chain, the curing point, etc. The

measurement of food temperature is also important

for health controls, where excesses of heat have been

shown to be related to the appearance of carcinogenic

products and other substances such as acrylamide. In

this way, thermography is also being widely used for

the control of frying, the melting of chocolate, in bakery

ovens, hot and cold smoking, etc.

Infrared radiation is not the only type of light that

can be used to determine the chemical properties of

a material. In Spain we are lucky to have one of the

most advanced synchrotrons in Europe, the ALBA,

thus giving the country’s food industry the chance to

use synchrotron radiation spectroscopy. Although the

operating principle does not change with respect to

NIR spectroscopy, synchrotron light makes it possible

to explore properties of materials with a more precise

level of detail, since synchrotron light is much more

energetic than infrared light. This enables the characterisation

of different types of food, such as oil or ham,

as well as certain packaging in order to optimise production

and manufacturing processes.

In order to obtain fine measurement of food properties,

the industry is also incorporating different types

of microscopes such as bright field microscopy or fluorescence.

While bright field microscopes serve to obtain

an enhanced and very sharp image of the sample

to be scanned, fluorescence microscopies have the

advantage that they only make certain components of

a material visible (those that give rise to fluorescence).

This enables the combination of microscopes in in-line

systems to quantify suspended particles in oil, wine,

or beer, as well as determining the existence of microorganisms

in raw materials, as IK4-TEKNIKER has

demonstrated with various devices. The novel system

developed by SixSenso is also noteworthy: a spin-off

created at ICFO, capable of combining a microfluidics

system and a fluorescence reader to measure levels of

bacteria concentration, count specific populations of

microorganisms, etc.

As we can see, photonics is leading a new revolution

in the food industry. Thanks to the implementation of

techniques such as those mentioned above, it adds

a new dimension to precision agriculture, which has

OVERVIEW

SECPHO

emerged as a new field in which photonics is being

used to monitor and increase crop yields. We must

not forget the application of photonic technologies in

the maritime field, which allow us to obtain a map of

water quality and observe the health of fish populations,

while also being useful in food processing and

packaging.

There is no doubt about the bright future that awaits

the food sector, which drives 5.8% of the GDP of

Spain’s economy and that must continue to encourage

both the adaptation and creation of photonic

technologies and basic research to maintain and increase

the high standards of excellence and productivity

achieved nowadays.

Infrared thermography

for the food industry

The measurement of temperature is an important

aspect in any industrial process. In food

companies, in addition to involving many stages

where temperature is present, this is also key for

improving the quality and safety in the control of

production processes. The control of the presence

of carcinogenic and mutagenic products

in heat-producing processes is a critical aspect

for ensuring food safety. Substances such as

acrylamide or organic compounds such as PAHs

or HCAs can be produced during baking, frying,

cooking, smoking processes, etc.

In this article we will demonstrate how infrared

thermography is an ideal tool for monitoring

these processes, since it is a non-destructive and

non-invasive technique, without direct contact,

capable of covering large areas quickly and efficiently.

CONTROLLING THE FORMATION

OF ACRYLAMIDE

Acrylamide is an industrial chemical substance formed

in foods with a high carbohydrate content during heating

at high temperatures and low humidity conditions

in processes such as baking, frying and toasting. Its

content in foods is regulated in the EU by Regulation

2017/2158, in force since 2018, which establishes

mitigation measures and reference levels to reduce its

presence. The food products referred to in the regulation

are:

• Potato crisps, chips, snack products, crackers and

other products based on potato dough;

• Bread, bakery products, pastries, confectionery

and biscuits;

• Breakfast cereals;

• Coffee, roasted coffee, instant coffee;

• Baby foods and processed cereal-based foods for

infants and young children.

16 LIGHT! by secpho


Courtesy of Europastry, S.A.

According to EU legislation, acrylamide is classified as:

• Category 1B carcinogenic substance

• Category 1B mutagen

• Toxic for Reproduction Category 2

The production of acrylamide content in food at the

domestic and industrial levels is, therefore, a public

health issue. The important factors that influence the

acrylamide formation process include the temperature

and the heating, cooking and frying times. In this

sense, Infrared Thermography serves to control:

• Frying temperatures, since acrylamide is formed

from 120ºC.

• Control of ovens at high relative humidity.

• Scalding temperature prior to frying at 70°C (10

to 15 min) with a reduction of acrylamide formation

by 65% and 96% for potato crisps and chips,

respectively.

MONITORING PAH FORMATION

Polycyclic Aromatic Hydrocarbons (PAH) are penetrating

environmental pollutants that are characterised

by their carcinogenic and mutagenic potential.

PAHs are ubiquitous, not only in all environmental media

(air, soil and water), but also in various foods that

we encounter in our daily lives.

PAHs are mainly formed by pyrolytic processes, such

as in grilled or smoked foods. Another effective ingestion

route for PAHs is mainly attributed to activities

carried out in the form of cooking (roasted, toasted

and fried) and processing at an industrial level. Some

factors that affect the formation of PAHs include: the

heat source, the heating distance, the design of the

food device and the type of combustion agent (coal,

wood, gas and electrical source). In order to avoid the

formation of PAHs, infrared thermography can control

the temperature in:

• Frying: PAHs are formed from 150ºC.

• Chocolate formation: for milk chocolate 49ºC and

for dark chocolate 82ºC.

• Bakery oven: PAHs are formed from 150ºC.

• Hot smoking: 130ºC in the cabin and 80ºC in the

meat.

• Cold smoking: temperature lower than 30ºC

(regulation of the air or by the passage of smoke

through a heat exchanger).

MONITORING HCA FORMATION

Heterocyclic Amines (HCAs) are organic compounds

that have two or more fused aromatic rings and an

amine group (–NH2). Like PAHs, they are ubiquitous

both in the environment and in various everyday

foods. They are characterised by their carcinogenic

and mutagenic potential and are formed from:

• Amino acid pyrolysis: Tryptophan, Lysine, Glutamic

Acid and Phenylalanine

• Carbolines

• Reaction between Maillard Reaction products

and creatine

• Aminoimidazoazarens

Some factors that affect the formation of HCAs include

the type of meat, the cooking duration and temperature,

the equipment and method of cooking, the

pH, the content of carbohydrates, free amino acids,

fat, creatine and/or creatinine.

In this context, Infrared Thermography serves to control

the temperature in:

• Frying high-protein foods: cooked meat and fish

from 150ºC.

• Industrial ovens from 150ºC.

Thermography acts as a non-contact temperature sensor for large areas, thanks to it being a non-invasive and

non-destructive tool that has been fully endorsed in process control. BCB has extensive experience in thermography,

available to the food industry through the bcbMonitor® product range. Inspection automation is achieved

by processing the images from one or multiple thermal imaging cameras and specific software which detects

deviations in the process and informs the operator or connects to other systems on the production line for their

correction.

PROCESSING AND SAFETY

Photonic technologies

revolutionise the food industry

The in-line inspection of food using vision systems is

one of the applications in greatest demand within the

food industry. The traditional artificial vision equipment

used to optimise and monitor bottling, packaging

and labelling processes, or classification by shape and

size, are giving way to new technologies that are redefining

the standards of quality control and production

optimisation. These new photonic technologies include

advanced spectroscopy, hyperspectral imaging,

thermography, infrared imaging and the application of

Deep Learning algorithms to artificial vision. The use of

these innovative techniques, whether individually or

combined, is allowing the food industry to accelerate

towards full characterisation, in situ and in real time, of

the visual aspect and the chemical composition of its

products.


PROCESSING AND SAFETY

ÁLAVA INGENIEROS

A hyperspectral camera is capable of collecting visual

and spectral information. Some of the typical applications

include: meat (measurement of the percentage

of fat and proteins, levels of tenderness, water content

and detection of contaminants and foreign bodies);

fruit (determination of the degree of texture, degree

of ripeness, sugar and water levels, organic acid content);

determination of ingredients that are very similar

in colour (different types of cheeses mixed in pizzas,

for example); nuts (classification and evaluation of almonds);

detection of allergens in flours; and the percentage

of histamine in tuna.

THERMOGRAPHY

Example of identification of foreign bodies by hyperspectral

camera

Finally, these applied technologies that are connected

to each other in the Industry 4.0 environment, supported

by others such as augmented reality (AR) or

virtual reality (VR) through IIoT (Industrial Internet of

Things) platforms, are actively participating in the digital

transformation of companies in the sector, leading

to process improvements, greater and better automation

of tasks and, ultimately, more efficient production

in all aspects.

This article explains what these technologies consist

of and how they are revolutionising production processes

and quality control.

HYPERSPECTRAL IMAGING

This technology enables spatial and spectral information

to be obtained without contact with the product,

thanks to it being a non-invasive technique that combines

the benefits of digital imaging and spectroscopy.

Another of the challenges in the food industry is the

control of organoleptic properties in products following

processes such as packaging and pasteurisation. In

this sense, the integration of thermographic cameras

in the line enables an automated control of the cold

chain to be carried out to guarantee controls on sealing

and an optimum state of packaging for food. This

is one of the most common causes of complaint in supermarkets

and is a concern for packaging companies.

The thermography applied to the quality control of

product packaging is especially useful in the control

of induction sealing, for checking if there is any presence

of frozen material inside an opaque container, for

determining if there is any vacuum loss, for controlling

the filling of opaque PET containers and for controlling

the gluing of cartons in distribution boxes.

Another outstanding application for thermography

lies in raw materials, in particular for: controlling the

cooking temperature on leaving the oven; maintaining

the cold chain in dairy products and/or refrigerated

products; determining the storage area in a cold silo

depending on the temperature of fruit when delivered;

as well as the curing point of meat products.

PROCESSING AND SAFETY

ADVANCED SPECTROSCOPY

Spectroscopy is based on the study of the interaction

of infrared light with a product. This technique allows

us to determine the main chemical composition of a

product and the identification of materials in a matter

of seconds.

The emergence of programmable portable NIR analysers

in the advanced spectroscopy field enables

multi-parameter measurement in the production

line as well as in the laboratory, even through plastic

containers. These devices enable the authentication,

identification and classification of raw materials, food

and contaminants.

Some of the applications in greatest demand include:

the adulteration of minced meat and other scams (the

differentiation of horse meat and beef); the optimisation

of mixed minced meat in the production line; the

adulteration of cocoa with wheat flour (detection of

wheat as an adulterant); the measurement of acetic

acid; quality control of oils; the detection and measurement

of acrylamides in cooking processes; the

measurement of particle sizes in flour; and the determination

of moisture content in snacks.

Thanks to the development of tailored, predictive

chemometric models, it is possible to customise such

equipment for its specific application.

THE IoT AND INDUSTRY 4.0

The current development of enabling technologies in

Industry 4.0, such as artificial vision, virtual and augmented

reality and IIoT, make traceability possible, in

addition to improvements in the production process

from start to finish.

Thanks to the sensorisation of machines and their connection

to servers in situ for the processing and classification

of data (Edge Computing) and its subsequent

analysis in the cloud (Cloud Computing), we can examine

and quantify information from the production process

based on a multitude of predefined parameters,

such as the number of products discarded by a given

supplier based on their acrylamide content, for example

(data that would be obtained from a portable NIR

analyser). This allows for faults to be predicted and

for the optimisation of complete industrial processes

based on the statistical analysis of all such data.

Real-time visualisation of such information from anywhere

in the world is possible thanks to AR & VR technology

and its connection to cloud servers. Depending

on how you wish to display the information, you can

view it from your own mobile phone pointing to a machine

or from the sofa at home, walking through the

factory using VR glasses.

of ecosystems. However, water quality control has historically

focused on discrete samples collected weekly

or monthly.

Additionally, solid food detection methods are often

insufficient in the sense that they are not sensitive

to errors and require a lot of time, due to the manual

or chemical selection of products based on samples.

Some of the main health risks consist of microorganisms,

either from the sources or involuntarily introducing

them into storage and/or distribution systems.

Unfortunately, with the timescales involved for this

type of microbial analysis when possible contamination

is revealed, it has already been distributed and

consumed. In general, decent monitoring methods are

lacking, both in food and water, so as not to put the

health of consumers at risk.

The optical measures applied to decide upon the quality,

identity and safety of foods are linked to the different

physical processes that occur when a wave of light

hits a biological substance. These interactions cause:

selective absorption, molecular vibrations, refraction

and fluorescence, among other reactions. These interactions

can be evaluated with different techniques in

the sensor technology field.

In view of all this, we at Eurecat have proposed to

explore the potential of photonics to respond to the

main challenges that can place our health at risk, both

in food products and in water. The use of photonic

sensors allows us to guarantee the monitoring of product

quality in real time, in an automatic, centralised

way and with a notable improvement (with respect to

the current detection systems used) in contaminant

detection sensitivity.

Optical measurements are the result of spectroscopic

investigations and are implemented in a practical detection

platform. For each application, a static demonstrator

is constructed that is representative of each

optical platform, which are required to verify the chosen

contaminants on a regular basis, applying standard

methods to predetermined sampling frequencies.

“We are world leaders

in olive sorting machines”

INTERVIEW with Simon Van Olmen, founding partner and CTO for the last 18 years for Multiscan

Technologies, a Spanish company specialising in the development, marketing and sale

of inspection machines with a presence in five continents.

Multiscan Technologies emerged

in 1996 thanks to the vision of

three enthusiastic friends who did

not have a workshop, but rather

a dining room at home. Are teamwork

and passion always the initial

drivers?

Yes, for sure, teamwork and passion

are essential; without united

human resources that have the

complementary and necessary

skills, the chances of success are

greatly reduced. In addition to the

team, the setting and timing are

also important. The setting provides

access to the necessary resources

and knowledge, and times

of change are always favourable

for the emergence of new companies

offering different products

and/or services. When we started

in 1996, making artificial vision

machines was neither evident nor

widespread, but technology was

starting to allow it.

Your project was conceived because

you captured a clear need

in the market for the classification

and selection of table olives, an

area in which Spain maintains its

global leadership. Do you remember

who took a chance on your

first automated sorting machines?

As is often the case, we chopped

and changed several times before

arriving at the artificial vision machines.

We started our activities by

26 LIGHT! by SECPhO


MULTISCAN

PROCESSING AND SAFETY

making public lighting control systems,

then software for handheld

terminals and virtual design software

with warping techniques and,

finally, our first artificial vision machinery

to classify olives by colour.

By having one of the market leaders,

Aceitunas La Española, in our vicinity,

this facilitated the development

of this first machine; in fact, La Española

became part of our project.

Introduce Multiscan to us: what is

your value proposition?

We at Multiscan create solutions

in sorting and X-rays for

the agri-food industry; these

solutions are highly optimised

and adapted to niche markets.

We specialise in the classification

of small-sized products

that can be rotated, and in systems

where we combine several

types of inspection, such

as X-rays and conventional

vision. This is where the name

of the company comes from

“multi” “scan”, from scanning

in multiple ways.

Since you started, 22 years have

now passed and today you continue

to be the owner, consultant and

a member of the Board of Directors.

What are the challenges for

Multiscan in the near future?

We are continuously expanding our

range of equipment with new solutions

for different products. We are

world leaders in olive sorting machines,

which we have been adapting

to different products, such as

cherries, cherry tomatoes, walnuts

and pistachios. At one point, and almost

by mistake, we started building

X-ray machines. I say “by mistake”,

because we wanted to detect

the remains of olive stones in pitted

olives, and we eventually realised

that olive stones are not calcified

as with human bones, and cannot

be detected. In any case, we finally

decided to continue with their development

and now we offer a full

range of X-ray inspection machines

for the food industry, with us being

the only national manufacturer.

“In an increasingly

demanding market, artificial

vision machines

are essential for optimising

production

processes and guaranteeing

quality”.

Multiscan Technologies is focused

on the design and manufacture of

machines, but in order to better

serve the needs of our customers,

we have set up Multiscan Systems,

which allows us to offer complete

turnkey lines, offering a large component

of added value. Industry

4.0 is emerging and we have many

ideas in order to offer new differential

solutions.

What is Multiscan’s customer profile?

We have customers of all sizes,

from micro-enterprises, who have

installed a cherry sorting machine

in their workshop, to large companies

such as Bimbo, Incarlopsa,

Dcoop, SBF, etc., which have installed

dozens of our machines in

large production lines. Nowadays,

in an increasingly demanding market,

artificial vision machines are

essential for optimising production

processes and guaranteeing quality.

At Multiscan, you speak of anticipation

as a constant process

of development for the company.

This avant-garde nature

leads you to allocate half of

your resources to R&D, as well

as to the incorporation of new

techniques and technologies.

Tell us about this innovative

commitment. What types of

technologies are you integrating

and who are your main

partners?

It is evident that, in a technological

company like ours,

innovation is a constant. We have

a large, internal R&D capability,

which we complement with a multitude

of external entities. As I said

before, the setting is very important

in order to facilitate access to

resources and knowledge. We have

the privilege of having the Polytechnic

University of Valencia very

close by, as well as a network of

cutting-edge Technological Institutes.

We have many technological

partners: UPV, UPM, AINIA, ITI,

DCM, etc. Among them, I would

like to highlight FYLA Laser, with

LIGHT! by SECPhO 27


PROCESSING AND SAFETY

MULTISCAN

whom we are working on a project

to integrate the Supercontinuum

laser into our sorting machines.

FYLA is one of the few manufacturers

worldwide that are capable

of producing this type of laser, and

they are located a stone’s throw

away from us in Paterna Technology

Park.

The Valencian Community has

been the largest European beneficiary

of the SME Guarantee Facility

for 2018 following the first call for

the development of highly disruptive

projects, and constitutes 30%

of Spanish companies. Multiscan is

among the beneficiary companies.

Congratulations! Why do you think

companies in the Valencian Community

have a high success rate?

Thanks very much! The truth is that

we are very proud to have been

one of the few companies that

have achieved an SME instrument

phase 2. It is noteworthy that, of

the 13 Spanish companies that

have achieved it, 4 are Valencian.

I believe it is the combination of

entrepreneurial spirit, the network

of Universities and Technological

Institutes, as well as strong support

from the Valencian Regional Government

for promoting Innovation.

The EVOOLUTION project is

aimed at industrialising a solution

for olive classification for oil production.

This solution enables great

improvements in the quality of the

oil, by eliminating defective olives

and even allowing classification by

the degree of ripeness, and all of

this at a rate of up to 50 tonnes/

hour.

You are passionate about artificial

intelligence, the IoT, artificial

vision... fields built on the technological

basis of photonics which

are now on the rise. What would

you say to those companies in the

food sector that feel removed from

all these trends at the moment?

The truth is that we are living in

exciting times, where technology

is evolving increasingly faster. Advances

in photonics, nanotechnology,

computing capabilities and

analytics are having a huge impact

on the entire industry. In the same

way that the internet and smartphones

have had a great impact on

our day to day lives, technological

advances in collaborative robots,

IoT, Cloud, Big data, 3D printing,

Blockchain, augmented and virtual

reality, among others, are having

and will have a great impact on the

industry. For the time being, it is still

mostly the large companies that are

launching their Industry 4.0 projects,

but I am confident that just

like smartphones have changed our

lives in a very short time, the same

thing will happen in the industry,

with a barrage of new services,

business and production models. I

recommend that all entrepreneurs

should be very aware of the changes

that are taking place. .

Sensors set up in drones,

used for agriculture

As a result of the recent popularisation of drones as

a work tool, and the proliferation of the numerous

applications that these unmanned vehicles offer in

an increasingly dynamic and technologically demanding

market, there is currently a rise in the use of such

equipment to make high-resolution orthophotos from

different sensors. The subsequent analysis of these

orthophotos enables different vegetation indices to

be obtained, such as the Normalized Difference Vegetation

Index, the Soil-adjusted Vegetation Index and

the Crop Water Stress Index. The latter is especially

interesting because of the sensor used to obtain it. It

is a sensor that is found in the part of the radiomagnetic

spectrum that captures temperature, specifically

the LWIR (long wavelength infrared), with a wavelength

between 8 and 15 μm, capable of capturing

temperature in a range of -80 to -89 degrees Celsius.

Thus, the crop water stress index can be defined

as the determination of the transpiration rate of a

crop by reading the leaf canopy temperature, taking

into account the temperature difference between

the leaf canopy and air within this parameter,

while always comparing it with crop areas that are

42 LIGHT! by secpho


not under stress conditions. In order to obtain canopy

temperatures, the LWIR sensor is integrated

into a drone, and, for the ambient temperature, periodic

average readings are made in the same time

window as the reading obtained using the drone.

However, beyond obtaining all these indices, the

drones allow us to obtain other geometric data, such

as the characterisation of crops or the calculation of

the leaf canopy area. One of the alternative ways of

examining changes experienced by the aerial part of

a crop during its cycle is from measurements of the

Drone equipped with RGB and thermographic sensors

fraction of soil covered by the crop vegetation, which

is very closely related to the canopy area. Knowing

the state and condition of the development of the leaf

canopy area, as well as its evolution over time, constitutes

fundamental data, since it is a useful variable

for characterising and evaluating the development

E-STRATOS

and growth of crops in fertility, productivity, water

requirements studies, etc. It also helps to evaluate

the density and biomass of the vegetation cover, as

well as the response of plants to environmental conditions

or to different crop management strategies.

The acquisition of images with the help of drones enables

wide spatial coverage, which increases the representativeness

compared to other methods, in addition

to obtaining a high-resolution image, with pixel sizes

of up to 2 cm. This high resolution enables quantitative

measurements of any particularity or area of interest

of a crop to be taken in a practically direct way.

By means of photogrammetric methods, a very

precise and high-density point cloud can be obtained,

equivalent to the data obtained with a Li-

DAR (Light Detection and Ranging) system to obtain

a three-dimensional model that can correctly characterise

the crop and adjust doses in treatments.

The results obtained, which are shown in the following

figure, indicate that this technique can be

an important tool for the determination, characterisation

and modelling of the vegetative structure,

not only with respect to the individual crop,

but also with respect to the farm as a whole.

The examples just described show the potential for

the use of drones in agriculture, but we must not forget

that a drone is merely transport; ultimately, it will

be the set of techniques and sensors that will allow

results to be obtained.

SYNCHROTRON ALBA

Food and packaging

under Synchrotron light

The ALBA Synchrotron, the only synchrotron light source that exists in Spain, employs unique techniques

and equipment that allow accurate information to be obtained regarding the internal structure, composition

and properties of products made for the food industry.

Since it began its activity in 2012, the ALBA Synchrotron has provided

its cutting-edge techniques to all those companies that require

unique characterisation of their products and processes. It currently

serves more than 1,800 academic and industrial users per year. The

number of companies requiring the services of the ALBA Synchrotron

is growing steadily, many of whom are repeatedly using it to

identify improvements in their raw materials, products or processes,

as well as for overcoming their innovation challenges.

Aerial image of the ALBA Synchrotron

The high quality and brightness of the synchrotron light provide for

exceptional characterisation of the micro and nanoscopic properties

of food and packaging, which represents an advantage over the more

conventional techniques in terms of levels of detection, quantification,

resolution and characterization of processes in situ.


In the food sector, the ALBA Synchrotron can be very

useful for:

01

02

Characterisation of raw materials and finished

products A wide variety of foods (such as ham,

meat or fish) and food emulsions (oils, fats, dairy

products), at different temperatures and mixing

conditions, can be characterised in order to understand

their properties or in order to obtain

optimal manufacturing conditions.

Biocompatibility in functional foods. These foods

provide nutrients with additional beneficial effects

on our health, such as calcium, magnesium,

selenium, etc. However, not all chemical forms of

these minerals are absorbed or are beneficial to

our body. Therefore, it is important to know the

chemical form of these nutrients during the food

manufacturing process and during its marketing

phase. This information can be obtained at the

ALBA Synchrotron.

03

Food packaging Certain containers contain different

physical and chemical barriers to provide

protection from moisture, oxygen or light. These

barriers are formed by thin layers of different

materials and their capacity to act as a barrier

against different environmental conditions depends

on their composition and chemical structure.

At the ALBA Synchrotron, the characteristics

of new flexible packaging has been studied

for its optimisation.

It is very simple for companies to interact with the ALBA Synchrotron. A single point of contact (industrialoffice@cells.

you believe that the ALBA synchrotron could be helpful for your company.

Innovative

solutions

in food

The food and beverage industry is the first in Spain

for production and exports. All records were broken

last year in terms of production and employment, with

an increase of 4% for the latter, exceeding the symbolic

figure of 500,000 direct jobs and 2.5 million indirect

jobs. This sector represents no less than 21%

of Spain’s total manufacturing industry. In addition, it

is a segment with a clear intention to export, having

exceeded the figure of €30 billion in 2017.

AINIA is a technology centre that has been helping

companies for more than 30 years through innovation

in its products and processes, as well as through the

provision of different services, with more than 700

associated enterprises. Since its inception, AINIA has

opted for light technologies to improve manufacturing

processes, monitor quality and control food safety.

Among the main photonic applications that have been

developed, protected and transferred to the industry,

the following stand out:

PACKAGING

AINIA

01

Monitoring of the plastic container sealing process using thermography

AINIA has patented an innovative container inspection system based on the analysis of the thermal

footprint after the sealing process, which is able to detect defects in the welding area caused by

product residues, folds, gaps, etc. This technique is capable of analysing 100% of production and

automatically adjusting the packaging process to the optimal conditions.

02 Detection of foreign substances

via hyperspectral imaging

Food and beverages are intended for human consumption,

so it is essential to guarantee their safety

and the absence of any foreign body that may have

been accidentally introduced into raw materials or

during the manufacturing process. The detection of

low-density foreign substances is a problem that is

not solved using conventional technologies. By contrast,

the new technologies used by AINIA, such as

infrared, terahertz and chemical imaging, have been

successfully applied here.

03 Crop monitoring through the use of sensorised drones and

data analysis using artificial intelligence techniques

Precision agriculture is a new field in which photonic technologies enable crop yields. By analysing

the interaction of light with plants, it is possible to learn if they are suffering from water

stress or if there is any disease present requiring tailored phytosanitary treatment. AINIA has

developed a platform based on a drone equipped with a hyperspectral camera with software

that analyses the complete spectral footprint to identify the needs of each plant.

Quality control and defect detection using advanced artificial vision systems

Foods are highly complex matrices to the extent that there are apples of many varieties and, within the

same variety, the colour, size and shape is highly variable. The detection of defects and classification by

physical characteristics are much more complex than with mechanical parts made using moulds; in addition,

production volumes are very high, equating to tonnes per hour.

Therefore, in order to automate the control and classification

processes, advanced vision systems with high-speed

sensors, high resolution and complex algorithms based on

artificial intelligence techniques need to be applied. AINIA

has extensive experience in applications used for packaging

inspection, defect detection and visual classification.

05 Measurement of internal quality and composition

in different matrices, at high speed, using

NIR spectroscopy

Resulting image

In the food and beverage industry it is essential to know the

composition to decide upon the intended use of the products

and classify them according to their characteristics. This

is the case with wine, olive oil, fruit and meat, among other

products.

Image: Checking for a perfect seal

AINIA has developed devices based on the interaction of infrared

light to infer the chemical properties of products in

real time and classify them. For example, it has developed a

method capable of automatically detecting if an aged wine

is oxidised inside the bottle in a production line, as well as

assessing the quality of olive oil in real time.

transfer quality control from the

laboratory to the production line

The application of photonic technologies to the agri-food sector has

meant a revolution in the field of food control, since it has enabled

measurements to be taken and a multitude of data on its quality and

properties to be recorded, in a precise, rapid and continuous way.

Thanks to these technologies, the industry operating in this sector

can substitute the long manual processes used to collect spot samples

for their subsequent submission to a laboratory for analysis,

for non-destructive measurements capable of offering precise and

varied information on food quality and safety throughout the entire

value chain.


NEEDS AND TRENDS

This revolution has not only been preceded by the

demands of consumers, but also by a series of needs

and trends that have arisen in the agri-food sector,

including:

Increased quality and safety requirements in production

entails the need to monitor increasingly

more parameters online and preferably for all

products, instead of sampling.

A reduction in operating and maintenance costs,

through preventive monitoring in real time.

The growing interest towards a customised diet.

The need to digitise the agri-food sector under

quality, safety and traceability parameters.

From the Basque technology centre IK4-TEKNIKER,

work has been combined in the field of sensor technology

with the integration of photonic technologies

to online measurement systems in various industrial

sectors, including agri-food. In this sector, the focus

has been on transferring the measurements from the

analysis laboratory to the plants or production lines,

facilitating their monitoring and quality control.

TECHNOLOGICAL CHALLENGE

The development of advanced sensors has been an important

challenge in itself, because it requires the integration

of heterogeneous technologies that become

more complex the stricter the operating conditions

and the regulations. This difficulty has been further exacerbated

because the devices need connectivity, to

be safe and cost effective, and to be able to operate

autonomously and unattended.

Added to this is the complexity involved in transferring

the principles of measurement to these devices

that have traditionally been applied at the laboratory

level, while maintaining the robustness, reliability and

repeatability of measurements during the entire useful

life of the equipment. Such requirements need the

proper combination and integration of various technologies

and areas of knowledge, from simulation elements

to the principles of Mechanics, Fluidics, Op-

LIGHT! by secpho 69


WINE AND OLIVE OIL SECTORS

IK4 · TEKNIKER

tics, Electronics and Communications. Finally, precise

knowledge is needed concerning the requirements

and applicable regulations in the operating environment

in which the sensor will later be located.

APPLICATIONS AND EXAMPLES

The solutions developed by IK4-TEKNIKER for the

monitoring of food quality include in-line microscopy

systems that detect, quantify and classify particles in

a fluid and are capable of detecting impurities or bubbles

in products such as oil, beer and wine, as well as

quantifying and typifying microorganisms or nutrients

in water.

For their part, sensor solutions based on Vis-NIR

spectroscopy enable, through fast, cost-efficient and

non-destructive measures, the identification of many

key parameters in solid and liquid foods, from the fat

content in cow’s milk or the alcoholic strength of a

wine to the ripeness of a fruit (kiwi, tomato or avocado,

among others) and the percentage of moisture in

liquids such as oils, and in solids such as flour.

Colorimetry techniques also contribute to the development

of appropriate solutions to measure parameters

as diverse as the turbidity of a fluid or the presence

of aromatic substances.

IK4-TEKNIKER is currently working on numerous photonic

technology applications for the agri-food sector,

such as the detection of allergens and pesticides by

spectroscopy and electrochemical methods; the detection

of pests in greenhouses through automated

inspection via 2D/3D and multispectral vision; and the

low-cost mass monitoring of environmental conditions

in farms or processing plants, by means of self-powered

IoT sensors, to guarantee the quality of the product,

as well as animal welfare and projection towards a

circular economy.

SixSenso is committed to

the rapid and portable measurement

of microorganisms in liquids

The Institute of Photonic Sciences (ICFO) has developed

a new cytometer based on a low cost, compact

and portable image sensor, which can automatically

measure the concentration of bacteria or all types of

microorganisms in liquids. This is the new SixSenso

cytometer, a spin-off project that is being developed at

the ICFO. Its portability and high compatibility make it

an appropriate instrument, both for sampling applications

in situ and for continuous monitoring of microbiological

presence and concentration in the production

line. As a result, it is the direct application solution for

some of the technological challenges of greater added

value in the food industry.

This microbiological sensor enables the detection of

low levels of bacteria concentration in food preparation,

in the monitoring of yeasts and fungi in the

production of beverages (beer, wine, etc.), and in bacteriological

control in all types of water, be it water

ICFO WINE AND OLIVE OIL

SixSenso is a

spin-off project that

is being developed

at the ICFO

for washing food, drinking water, industrial water,

waste water, sewage, etc. The system has been successfully

validated against qPCR and culture under

the framework of a European project (CYTO-WATER,

2015-2018) for the early detection of Legionella (L.

pneumophila) outbreaks in cooling towers and E. Coli

in seawater. This early detection of very low levels of

bacteria greatly benefits food producers by minimising

outbreaks due to contamination.

The complete system combines a proprietary microfluidics

system for sample preparation with a fluorescence

reader based on a low-cost sensor matrix. The

total levels of bacteria concentration can be measured

(Total Bacteria Count: TBC), as well as the ratio

between living and dead microorganisms (Total Viable

Count: TVC), or specific populations of microorganisms

can be counted. The reader enables microorganisms

to be counted with fluorescent labelling and sensitivity

of up to 10 CFU/ml (CFU: Colony-Forming Unit).

To achieve the most exacting levels of detection, the

system has a concentrator module that increases the

concentration of microorganisms in the sample to be

analysed by a factor of 1,000, allowing this bacteria

counter to achieve detection limits of up to 10 CFU/l.

Image: Stand-alone cytometer

Although the culture procedure allows these very low

levels of bacteria to be measured, it takes days to do

so. Likewise, commercial flow cytometers are very

bulky, expensive and in addition do not offer sufficient

sensitivity in many cases, requiring experienced operators

for the prior preparation of the sample, which

distances them from their use as an integrated in-line

or in situ solution. By contrast, the presented cytometer

concentrates, marks and measures in one single

system and is offered as a reliable and economical

solution for the preparation and analysis of fully automatic

and integrated samples, with a repeatability and

precision that enables bacteriological concentrations

to be guaranteed below the limits required in current

food regulations.

Quality detection of food

via your mobile

The Institute of Micro and Nanotechnology (IMN) of

the National Scientific Research Council in Spain (CSIC)

has developed an optical sensor with several advantages

including remote optical detection and no need

for marking, that is easy to use and does not require

complicated optical systems or large magnification for

detection purposes, since it can be used by means of

a smartphone. The sensor’s manufacturing process is

simple and very low cost, offering potential for largescale

production. The sensor can find a practical use

in applications that require rapid, simple and portable

detection, as is the case in the detection of quality in

certain foods. In particular, the sensor is especially indicated

for the detection of liquid or viscous substance

mixtures, such as bio-solutions or liquid or viscous

food products such as water, oils, alcohol, wines, etc.

This sensor is manufactured on thin glass or plastic of

approximately 1x1 cm in size. It incorporates a dense

network of metallic nano-threads manufactured using

a simple nano-stamping technique developed at the

IMN-CSIC. The nano-threads are especially sensitive

to the environment that surrounds them and, when

they are in contact with the medium to be detected

(for example, when depositing a drop of the sample on

them), they produce a change in the optical signal detected

through the video camera on a mobile phone.

This change is evaluated using an application specifically

designed for detection.

The sensor measures the optical properties of the

medium in which it is submerged, so its use is very

wide-ranging. Some examples of applications include

the determination of alcohol in water, by measuring

concentrations of up to 3% in the volume of a drop

of water; determination of the purity of an olive oil

(whether or not it is mixed with other substances, other

oils or even if it is of an extra or another category);

determination of the quality and concentration of alcohol,

for example in both beverages with a high alco-

holic content (brandy, etc.) and a low alcoholic content

(wine, beer, etc.); or identification of specific labelling

and safety.

It should be noted that the sensor can detect from a

volume as small as 0.0025 ml (one drop or a thin layer)

masses in a solution of 0.1 mg or volumes of 0.0001

ml in another alternative substance. Detection can be

carried out in an approximate timeframe of 1 second.

Once the detection is complete, the sensor can be discarded

for recycling.

It provides extreme light intensity and is very easy to install. Its optimal

characteristics enable the lighting of hard-to-access areas or

areas where traditional lights create shadows or shade. In addition,

it guarantees a long and useful life thanks to its proven quality, and

together with a vision sensor, it can find errors in the production

process. All this translates into a reduction in costs, installation and

maintenance.
