What is Pasteurization?

Pasteurization (or pasteurisation) is the process by which packaged and non-packaged food products (such as juice and dairy products) are mildly heated, usually to less than 100 °C, to kill off harmful bacteria and other disease-causing pathogens, so that products life would be extended and become safe for consumption

Unpasteurized food, such as raw milk, may be safe for consumption, but normally for a short period of time in comparison to the products that have undergone pasteurization.

Pasteurization was invented by a French Chemist called Louis Pasteur in 1864.
