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.
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] UHT is most commonly used in milk production, but the process is ...
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 ...
Pasteurizing eggs in their shells is achieved through a technique that uses precise time and temperature zones within water baths. [ 14 ] [ 15 ] Pasteurizing eggs in their shells can also be achieved through a process that involves treatment with ozone and reactive oxygen species under high and low pressures, followed by replacement with an ...
Z-value is a term used in microbial thermal death time calculations. It is the number of degrees the temperature has to be increased to achieve a tenfold (i.e. 1 log 10) reduction in the D-value. The D-value of an organism is the time required in a given medium, at a given temperature, for a ten-fold reduction in the number of organisms.

The Food and Drug Administration said Thursday that traces of the bird flu virus have been found in 1 in 5 samples of pasteurized milk, providing a more detailed picture of how much of the milk ...
Food preservation includes processes that make food more resistant to microorganism growth and slow the oxidation of fats. This slows down the decomposition and rancidification process. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food ...
