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.
Pasteurization is widely used to prevent infected milk from entering the food supply. The pasteurization process was developed in 1864 by French scientist Louis Pasteur, who discovered that heating beer and wine was enough to kill most of the bacteria that caused spoilage, preventing these beverages from turning sour. The process achieves this ...
Pasteurization, discovered by Louis Pasteur in 1864, improved the quality and safety of preserved foods and introduced the wine, beer, and milk preservation. A form of pre-made split-pea soup that has become traditional
Although Appert had discovered a new way of preservation, it was not understood until 1864 when Louis Pasteur found the relationship between microorganisms, food spoilage, and illness. [ 5 ] Foods have varying degrees of natural protection against spoilage and may require that the final step occurs in a pressure cooker .
[4] [6] According to a legend originating in the 1900 biography of Pasteur, one of his chemistry students—an owner of a beetroot alcohol factory in Lille—sought aid from him after an unsuccessful year of brewing. [6]
In 1879, he became a professor of agricultural chemistry at the Technical University of Munich. [ 1 ] 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.
Acceptance of the different food technologies varies. While pasteurization is well recognized and accepted, high pressure treatment and even microwaves often are perceived as risky. Studies by the Hightech Europe project found that traditional technologies were well accepted in contrast to innovative technologies. [15]
