Pasteurization originated from Pasteur's efforts to solve the problem of beer souring. It is a disinfection method that can kill germs at low temperature and keep the flavor of nutrients in articles unchanged. It is often widely used to define heat treatment methods that need to kill various pathogenic bacteria.

Pasteurization is also used to sterilize beer, liquor and other things. Pasteurized beer is called cooked beer, which is ordinary beer. Draft beer is beer that can only be frozen and kept fresh without pasteurization.
Disinfection principle
In a certain temperature range, the lower the temperature, the slower the bacterial reproduction; The higher the temperature, the faster the reproduction. But if the temperature is too high, the bacteria will die. Different bacteria have different optimum growth temperature and heat and cold tolerance. In fact, pasteurization is to use the characteristics of bacteria that are not very heat-resistant, and treat them with appropriate temperature and heat preservation time to kill them all.
