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.
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.
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.
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 ...
Canning involves cooking food, sealing it in sterilized cans or jars, and boiling the containers to kill or weaken any remaining bacteria as a form of sterilization. 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.
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.
So it is clearly 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 add preservatives that prevent juice from fermenting and souring.

The original grandstand at the racetrack known today as Churchill Downs did not have the iconic Twin Spires. When the track opened in 1875 for the first Kentucky Derby 150 years ago, things were ...
