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.
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.
Louis Pasteur ForMemRS (/ ˈ l uː i p æ ˈ s t ɜːr /, French: [lwi pastœʁ] ⓘ; 27 December 1822 – 28 September 1895) was a French chemist, pharmacist, and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization, the last of which was named after him.
Dadiah is a traditional fermented milk of West Sumatra, Indonesia prepared with fresh, raw, and unheated buffalo milk. Fermented milk products or fermented dairy products, also known as cultured dairy foods, cultured dairy products, or cultured milk products, are dairy foods that have been made by fermenting milk with lactic acid bacteria such as Lactobacillus, Lactococcus, and Leuconostoc.
In biochemistry, fermentation theory refers to the historical study of models of natural fermentation processes, especially alcoholic and lactic acid fermentation. Notable contributors to the theory include Justus Von Liebig and Louis Pasteur , the latter of whom developed a purely microbial basis for the fermentation process based on his ...
Pasteur had already discovered molecular chirality, investigated fermentation, refuted spontaneous generation, inspired Lister's introduction of antisepsis to surgery, introduced pasteurization to France's wine industry, answered the silkworm diseases blighting France's silkworm industry, attenuated a Pasteurella species of bacteria to develop ...
Curd is made by bacterial fermentation of milk. In this process, lactose in milk is converted into lactic acid by several probiotic microorganisms.The species involved in the fermentation depends on the temperature and humidity of the environment and may include Lactococcus lactis, Streptococcus diacetylactis, Streptococcus cremoris, Lactobacillus delbrueckii subsp. bulgaricus and ...
Grapes being trodden to extract the juice and made into wine in storage jars. Tomb of Nakht, 18th dynasty, Thebes, Ancient Egypt. Sourdough starter. In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—without an oxidizing agent being used in the reaction.
