Abstract
A method for sanitizing food products that utilizes ozone containing bubbles. The food product is immersed in a liquid bath that has a plurality of ozone containing bubbles streaming therethrough. Enough ozone containing bubbles are provided such that a continuous stream of bubbles are always present within the liquid bath. The ozone containing bubbles are typically an ozone air mixture and can be introduced into the liquid bath directly as a bubble gas stream or can be mixed with the liquid of the liquid bath prior to their introduction into the bath itself. When the food product is immersed in the bath containing the ozone containing bubbles, the ozone in the bubbles contacts the surfaces of the food product and has a sanitizing effect thereon.
