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 ...
[4] This requirement was about 25 years before Welch used pasteurization, so it is evident that pasteurization was not the only method used to prepare it unfermented. There were traditional methods to prepare unfermented wine (juice) for use at any time during the year, e.g. to reconstitute concentrated grape juice, or to boil raisins, or to ...
It was invented by the French confectioner Nicolas Appert. [4] By 1806, this process was used by the French Navy to preserve meat, fruit, vegetables, and even milk. 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 ...
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.
Industrial cheese production. Food processing is the transformation of agricultural products into food, or of one form of food into other forms.Food processing takes many forms, from grinding grain into raw flour, home cooking, and complex industrial methods used in the making of convenience foods.
Flash pasteurization, also called "high-temperature short-time" (HTST) processing, is a method of heat pasteurization of perishable beverages like fruit and vegetable juices, beer, wine, and some dairy products such as milk. Compared with other pasteurization processes, it maintains color and flavor better, but some cheeses were found to have ...
