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 ...
Raw milk refers to the milk of an animal—typically a cow but also a goat or sheep—that has not been pasteurized. Pasteurization is the heat-treatment process, named for inventor Louis Pasteur ...
By 2005, the process was being used for products ranging from orange juice to guacamole to deli meats and widely sold. [35] Depending on temperature and pressure settings, HP processing can achieve either pasteurization-equivalent log reduction or go all the way to achieve sterilization of all microbes. [36]
Pasteurization is key because it involves heating an egg to a specific temperature, which would kill any bird flu that was present. You also want to make sure the pasteurized eggs you buy are in ...
Heat applied during pasteurization varies from around 60 °C to kill bacteria to around 80 °C to kill yeasts. Most pasteurization processes have been optimized recently to involve several steps of heating at various temperatures and minimize the time needed for the process.
