The methods of canned sterilization include heat sterilization, flame sterilization, radiation sterilization and high pressure sterilization, etc. The most widely used is still heat sterilization. Commonly used sterilization methods include intermittent static high pressure sterilization, intermittent static atmospheric pressure sterilization, and continuous atmospheric pressure sterilization.

Moreover, small cans can be directly cooled by atmospheric pressure when pasteurized. However, when cans with a diameter of 102mm or more are sterilized at temperatures above 116 degrees Celsius, and cans with a diameter of <102mm are sterilized at temperatures above 121 degrees Celsius, they need to be cooled by back pressure cooling.
