The original method of pasteurization was vat pasteurization, which heats milk or other liquid ingredients in a large tank for at least 30 minutes. It is now used primarily in the dairy industry for preparing milk for making starter cultures in the processing of cheese, yogurt, buttermilk and for pasteurizing some ice cream mixes.
UP pasteurization results in a product with longer shelf life but still requiring refrigeration. Call an Environmental Public Health office in your area to ask about how to pasteurize other types of food.
