Processing
Eco-Friendly, Energy Saving, Hygienic:
Efficient Sanitization with Microwave and
Radio Frequency Systems
SAIREM, a world-leading specialist in
microwave (MW) and radio frequency
(RF) industrial solutions based in Lyon,
France, showcase the company’s
sanitisation technologies at Food
Ingredients Europe. The company
innovative systems which are
suitable for either decontamination of
ingredients such as powders, spices,
peppercorns, flours, and nuts etc. or
as disinfestation of plant-based food
and ingredients such as, cereals, soft
wheat and many more. Responding to
client needs, the French company has
developed highly efficient processes to
produce ingredients that are healthy,
clean, and fully compatible with the
requirements of organic farming
certification.
Chemical free destruction
of potentially contaminated
ingredients
Decontamination with Sairem RF and
MW systems enable the complete
destruction of mould, yeast, and bacteria,
without the use of toxic chemical
products. The use of not allowed gas
was one of the most cited reasons for
product withdrawal in Europe the last
years. This is a major advantage for food
processors and suppliers serving the
health -and environment- conscious
consumers of today. Sairem’s systems
are ideal for superfood trend products
and ingredients to produce plantbased
protein alternatives. Valuable
ingredients such for example nuts are
treated with extreme care, therefore
resulting in a high-quality end product
and reduction of 4-5 Log. The efficient
RF and MW process, which only lasts
a few minutes, ensures that each
ingredient is quickly and uniformly
brought to the required temperature. As
the processing time is so short, there is
no alteration of the physical, chemical,
and organoleptic properties - all product
characteristics are perfectly preserved.
Other successful applications include
peppercorns (3.4 Log reduction)
or maize starch powder (6,87 Log
reduction).
RF and MW technology for
disinfestation from egg to insect
Many high-quality ingredients are
exposed to the risk of contamination
SAIREM's MW and RF technology is 100% electric and therefore produces no CO 2
emissions and consumes 50% less energy compared to traditional heat
treatment processes.
