Thermization, also spelled thermisation, is a method of sterilizing raw milk with heat. The process is not used on other food products,[1] and is similar to pasteurization but uses lower temperatures, allowing the milk product to retain more of its original taste.[2] In Europe, there is a distinction between cheeses made of thermized milk and raw-milk cheeses. However, the United States' Food and Drug Administration (FDA) places the same regulations on all unpasteurized cheeses. As a result, cheeses from thermized milk must be aged for 60 days or more before being sold in the United States, the same restriction placed on raw-milk cheeses by the FDA.[3]
