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.
In the UK and NI, the Danger Zone is defined as 8 to 63 °C. [7] Food-borne bacteria, in large enough numbers, may cause food poisoning, symptoms similar to gastroenteritis or "stomach flu" (a misnomer, as true influenza primarily affects the respiratory system). Some of the symptoms include stomach cramps, nausea, vomiting, diarrhea, and fever ...
The refrigerator should be at 40°F (4.4°C) or below and the freezer at 0°F (-17.7°C) or below. [ 27 ] For example, liquid foods like soup kept in a hot slow cooker (149°F or 65°C) may last only a few hours before contamination [ citation needed ] , but fresh meats like beef and lamb that are promptly frozen (-2°C) can last up to a year.
At this temperature, bacteria are killed, enzymes in the milk are destroyed, and many of the proteins are denatured. [2] Since most milk sold today is pasteurized, which accomplishes the first two goals, milk is typically scalded to increase its temperature, or to change the consistency or other cooking interactions by the denaturing of ...

In 1912, a continuous-flow, direct-heating method of mixing steam with milk at temperatures of 130 to 140 °C (266 to 284 °F; 403 to 413 K) was patented. However, without commercially available aseptic packaging systems to pack and store the product, such technology was not very useful in itself, and further development was stalled until the ...
