In the food industry is very important to keep maximum levels of hygiene and safety against germs that can damage products. The legislation is becoming more strict about it; but the bacteria, fungi and yeasts have ease to grow in every corner. This is where UV sterilization systems come in.
Despite the UV radiation has high bactericidal and fungicidal power, is not advisable to directly irradiate every food with it; since its high oxidation power can impair food changes in taste or discoloration.
Cases like spices, flour, cereals, legumes, powder and fat-free products cannot be deteriorated by this method.
But if we can not directly irradiate with UV light many foods, how we can do it? In most cases the sources of contamination of these foods are usually beyond the product itself, and may result from the contact with contaminated surfaces, tainted environment, handling or previous processes with lack of the necessary hygiene… So it is at these points where you have ‘to attack’ to avoid generating these infections.
The safest and most reliable methods are keeping clean all surfaces in contact with the product, and an air as pure as possible. For this, the ultraviolet light is ideal. Simply irradiating the transporter and places close to the food, and ‘cleaning’ the environment of germs in suspension. This method reduces its number considerably, obtaining a substantial improvement in product quality aswell.
On the other hand, special attention should be paid in packaging. Treating it with UV light facilitates the compliance of quality standards and reduce the use of chemical additives to the product.
