How does UV light extend the shelf life of fruits and vegetables?

Using a patented ultraviolet-enhanced oxidation technology, Bluezone by Middleby destroys chemical and biological impurities in the air rather than concentrating and capturing them with a particle filter or activated carbon.

Units work by removing ethylene gas, which is the top cause of produce decay. Ethylene frequently builds up inside refrigerated spaces where fruits and vegetables are stored, and eliminating it ultimately reduces food waste and saves money. This breakthrough approach to food preservation was specifically developed for the U.S. Army to extend the shelf life of fresh fruit and vegetables in shipping containers sent to troops overseas, and now it’s available for your commercial kitchen.
