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.
Lactotripeptides are two naturally occurring milk peptides: Isoleucine-Proline-Proline (IPP) and Valine-Proline-Proline (VPP). These lactotripeptides are derived from casein, which is a milk protein also found in dairy products. Although most normal dairy products contain lactotripeptides, they are inactive within the original milk proteins.
The Gerber method is a primary and historic chemical test to determine the fat content of substances, most commonly milk and cream. [1] The Gerber method is the primary testing method in Europe and much of the world. [ 2 ]
Today, the process is mainly applied to dairy products. In this method, milk is heated at about 70 °C (158 °F) for 15–30 seconds to kill the bacteria present in it and cooling it quickly to 10 °C (50 °F) to prevent the remaining bacteria from growing. The milk is then stored in sterilized bottles or pouches in cold places.
UHT is most commonly used in milk production, but the process is also used for fruit juices, cream, soy milk, yogurt, wine, soups, honey, and stews. [3] UHT milk was first developed in the 1960s and became generally available for consumption in the 1970s. [ 4 ]
Casein is the primary emulsifier in milk, that is, it helps in mixing oils, fats, and water in milk. [3] Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive. [4] The most common form of casein is sodium caseinate (historically called nutrose), which is a very efficient emulsifier.

[14] [18] This process, called genome erosion or reductive evolution, has been described in several other lactic acid bacteria. [ 19 ] [ 20 ] The proposed transition from the plant to the dairy environment was reproduced in the laboratory through experimental evolution of a plant isolate that was cultivated in milk for a prolonged period.
