Disclosed is a method for sanitizing a food product, comprising applying an aqueous sanitizing liquid onto the food product by spraying it onto all exterior surfaces of the food product from a plurality of directions while moving the food product laterally with respect to the sprays, wherein the velocity of each spray is sufficient to wet microbes adhered to the surface of the food product, wherein the sanitizing liquid comprises ozone at a concentration of up to 15 ppm, and preferably also comprises at least one agent which inactivates food microbes wherein said agent is present in a concentration sufficient to inactivate food microbes, maintaining contact between said sanitizing liquid and said food product for at least a time effective to maximize wetting of the surface of the food product by the sanitizing liquid containing said at least one agent, and then removing mechanically at least 75 % of said liquid from said food product.

L'invention se rapporte à un procédé d'aseptisation d'un produit alimentaire consistant à appliquer un liquide d'aseptisation aqueux sur le produit alimentaire par pulvérisation de ce dernier sur toutes ses surfaces extérieures, selon une pluralité de directions, tout en déplaçant ledit produit alimentaire latéralement par rapport au pulvérisateur, la vitesse de chaque pulvérisateur étant suffisante pour humidifier les microbes adhérant à la surface du produit alimentaire. Ledit liquide d'aseptisation comprend de l'ozone à une concentration pouvant atteindre 15 ppm, et comporte également de préférence au moins un agent inhibant les microbes alimentaires, ledit agent étant présent à une concentration suffisante pour assurer l'inhibition des microbes alimentaires. Le procédé consiste ensuite à maintenir le contact entre le liquide d'aseptisation et ledit produit alimentaire pendant un laps de temps suffisant de manière à maximaliser l'humidification de la surface du produit alimentaire par le liquide d'aseptisation contenant au moins ledit agent, et enfin à retirer mécaniquement au moins 75 % de ce liquide du produit alimentaire.
