  • Cold water disinfection of foods
    Patent number: 6458398
    Abstract: The invention includes a method of reducing the microbial population on food in a container. The method generally involves the application of both a surfactant and ozone containing wash liquor to the food. The method includes introducing a wash liquor into the container, thus contacting the food with the wash liquor and wetting the food. A surfactant is then added to the wash liquor. This surfactant containing wash liquor is then allowed to contact the food for a period of time. Next, a combination of ozone gas, oxygen and/or air is mixed into the wash liquor to form an ozonated wash liquor. This ozonated wash liquor then remains in contact with the food for a period of time.
