Pasteurization vs. Tyndallization

Pasteurizationnoun

A process devised by Pasteur for preventing or checking fermentation in fluids, such as wines, milk, etc., by exposure to a temperature of 140° F., thus destroying the vitality of the contained microorganisms.

Pasteurizationnoun

partial sterilization of foods at a temperature that destroys harmful microorganisms without major changes in the chemistry of the food

Pasteurization

Pasteurization or pasteurisation is a process in which packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. The process is intended to destroy or deactivate organisms and enzymes that contribute to spoilage or risk of disease, including vegetative bacteria, but not bacterial spores.The process was named after the French microbiologist, Louis Pasteur, whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine.

Tyndallization

Tyndallization is a process dating from the nineteenth century for sterilizing substances, usually food, named after its inventor, scientist John Tyndall, that can be used to kill heat-resistant endospores. Although considered old-fashioned, it is still occasionally used.
