Pasteurized milk in Japan A 1912 Chicago Department of Health poster explains household pasteurization to mothers.. In food processing, pasteurization (also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
A Tetra Pak ultra-pasteurization line. Ultra-high temperature processing (UHT), ultra-heat treatment, or ultra-pasteurization [1] is a food processing technology that sterilizes liquid food by heating it above 140 °C (284 °F) – the temperature required to kill bacterial endospores – for two to five seconds.

Flash pasteurization, also called "high-temperature short-time" (HTST) processing, is a method of heat pasteurization of perishable beverages like fruit and vegetable juices, beer, wine, and some dairy products such as milk. Compared with other pasteurization processes, it maintains color and flavor better, but some cheeses were found to have ...
The most common method of pasteurization in the United States today is High Temperature Short Time (HTST) pasteurization, according to the International Dairy Foods Association. This process uses ...
Pasteurization was adopted in the U.S. in the 1920s as a way to reduce foodborne illness in milk. Raw milk benefits There are a few reasons why some people prefer raw milk over pasteurized milk.
Pasteurization is the process of heating a food to kill harmful bacteria. This law has been in place since 1987, but milk pasteurization existed for 100 years before that.
Pasteurization temperatures can reach 161 °F (71.7 °C). This temperature is high enough to denature the proteins below, lowering the nutritional value of the milk and causing fouling. Milk is heated to these high temperatures for a short time (15–20 seconds) to reduce the amount of denaturization. However fouling from denatured proteins is ...
Raw milk may be new for many people, but it’s not a new phenomenon. In fact, before pasteurization was commonplace, all milk was raw. The process of heating milk before it's bottled and put on ...
