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.
The FDA accepts that microwaves can be used to heat food for commercial use, pasteurization and sterilization. [4] The main mechanism of microbial inactivation by microwaves is due to thermal effect; the phenomenon of lethality due to 'non-thermal effect' is controversial, and the mechanisms suggested include selective heating of micro-organisms, electroporation, cell membrane rupture, and ...
The pasteurization-equivalent is generally referred to as simply HHP (along other synonyms listed above), while the heated sterilization method is called HPT, for high pressure temperature. Synonyms for HPT include pressure-assisted thermal sterilization (PATS), pressure-enhanced sterilization (PES), high pressure thermal sterilization (HPTS ...
Cold pasteurization may refer to: . Pascalization, a method of preserving and sterilizing food, in which a product is processed under very high pressure; Food irradiation, exposing foodstuffs to ionizing radiation to preserve food, reduce the risk of food borne illness, prevent the spread of pests, delay or eliminate sprouting or ripening, increase juice yield, or improve re-hydration
PEF for food processing is a developing technology still being researched. There have been limited industrial applications of PEF processing for the pasteurization of fruit juices. To date, several PEF treated juices are available on the market in Europe. Furthermore, for several years a juice pasteurization application in the US has used PEF.
Some of the more prominent advantages of these types of processes are that they require simple equipment and they are effective for both enveloped and non-enveloped viruses. Because pasteurization involves increasing the temperature of solution to a value that will sufficiently denature the virus, it does not matter whether the virus has an ...

Aseptic products have a non-refrigerated shelf-life of a few months to several years. Sterilization of aseptic packaging material is a crucial step in aseptic food processing. These containers are sterilized to kill microorganisms present on the container during forming and transport and prior to filling. [8]
