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.
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.
Milk pasteurization became popular in America around 1920. [26] In 1921 Albert Calmette and Camille Guérin of Pasteur Institute introduced tuberculosis vaccine, whose virulence of strains varied in the late 1920s. [35] BCG vaccine was not used in the public health of America, which virtually eliminated tuberculosis without it.
The previous incorrect distinction had stemmed in part from the fact that yeast had to be added to beer wort in order to provoke desired alcoholic fermentation, while the fermenting catalysts for wine occurred naturally on grapevines; the fermentation of wine had been viewed as 'artificial' since it did not require additional catalyst, but the ...
He invented the Soxhlet extractor in 1879 and in 1886 he proposed pasteurization be applied to milk and other beverages in order to prevent disease and spoilage. Soxhlet is also known as the first scientist who fractionated the milk proteins in casein , albumin , globulin and lactoprotein.
Thomas Bramwell Welch (December 31, 1825 – December 29, 1903) was a British–American Methodist minister and dentist.He pioneered the use of pasteurization as a means of preventing the fermentation of grape juice.
The pasteurization process destroys the virus’s ability to live or replicate, making pasteurized milk safe. However, raw milk has been shown to contain the virus.
1871 – Louis Pasteur invents pasteurization; 1895 – Refrigeration for domestic and commercial drink preservation introduced in the United States and the United Kingdom, respectively. 1913 – The Haber process, also called the Haber–Bosch process, made it possible to produce ammonia, and thereby fertilize, on an industrial scale.
