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.
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 ...
Since pasteurization affects a wine's flavor and aging potential it is not used for premium wines. A gentler procedure known as flash pasteurization involves heating to 205 °F (96 °C) for a few seconds, followed by rapid cooling.
A process called flash pasteurization rapidly heats the wine to the desired temperature and immediately chills it back to room temperature. This process is said to have a minimal effect on flavor, at least to the casual wine drinker.
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 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 .
During the pasteurization process, the vinegar is heated to neutralize the live bacteria and other microorganisms and stop fermentation, which produces a clear, stable product with a clean ...
