Potencialidades do uso do ozônio no processamento de alimentos

Abstract

Ozone is a colorless and unstable gas with pungent smell and partially soluble in water, which is characterized by its high oxidant power. It is a strong agent disinfectant with high power germicidal properties acting in the inactivation of a wide variety of pathogenic organisms, including bacteria, virus and protozoa, presenting a germicidal efficiency that exceeds chlorine. Ozonization has become wellknown in recent decades due to implementation of standards increasingly restrictive concerning the by-products of chlorination. Unlike chlorine, ozone do not form halogenated compounds with organic matter. However, it may form several other organic and inorganic. In the food industry, ozone can be use in sanitization processes of equipments and surfaces, as well as in the direct use on foodstuff in order to inactivate microorganisms and to extend shelf-life of food products. © Pleiades Publishing, Ltd., 2011.
