Food Hygiene With UV Light

Mold is among the most annoying and persistent pests on food. Once it has settled in, said food is often only fit for the garbage bin because the toxins in mold are among the most dangerous substances in the world. It even spreads in the refrigerator because it can thrive at sub-zero temperatures. Thus, temperatures between 2°C and 8°C do not present a risk for mold.

The situation is different with UV radiation: Experiments have shown that mold spreads more slowly under radiation in the wavelength range from 220 nm to 340 nm. In addition, the radiation also destroys some of the harmful toxins. Furthermore, radiation has a well-known antibacterial effect: the dreaded salmonellae cannot withstand ultraviolet waves either.
