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 ...
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. [2]
It could be that the juice is microbe-free ahead of the pasteurization step, but by using pasteurization, the cider is made that much safer.” There’s another reason cider is pasteurized: shelf ...
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 ...
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. [13] Basic drawing of an ammonia compressor.
Before pasteurization, people routinely were sickened and died from drinking raw milk, catching diseases like tuberculosis, and raw milk is still far more likely than pasteurized milk to contain ...
Pasteurization is widely used to prevent infected milk from entering the food supply. The pasteurization process was developed in 1864 by French scientist Louis Pasteur, who discovered that heating beer and wine was enough to kill most of the bacteria that caused spoilage, preventing these beverages from turning sour. The process achieves this ...
