Installing ozone generators in the cold rooms and inside the store we manage to eliminate pathogens (viruses, bacteria, spores, fungi ... etc.), remains of pesticides and chemical and biological contaminants from the environment. This gas has the ability to quickly eliminate the various volatile metabolites, such as aldehydes or ethylene that are released by vegetables and which are responsible for accelerating their ripening process. Adding ozone gas to the atmosphere where vegetables are stored delays their alteration by up to 30%. Ozone not only preserves them, but also maintains their caliber, consistency, organoleptic properties and quality for a longer time while we achieve a clean and well-kept environment in the premises.
