Pasteurization



Pasteurization (American English), also spelled pasteurisation (British English), is a process that kills bacteria in liquid food.
It was invented by French scientist Louis Pasteur during the nineteenth century. In 1864, Pasteur 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 by eliminating pathogenic microbes and lowering microbial numbers to prolong the quality of the beverage. Today, pasteurisation is used widely in the dairy and food industries for microbial control and preservation of food.
