Food canning is to put the processed food into tinned thin-plate cans, glass cans or other packaging containers, seal and sterilize, so that the food in the cans is isolated from the outside world and no longer contaminated by microorganisms. At the same time, most microorganisms in the cans (namely spoilage bacteria and pathogenic bacteria that can grow in the environment of the cans) are killed and enzymes are inactivated, thus eliminating the main causes of food spoilage and obtaining a preservation method of long-term preservation at room temperature. This kind of food, which is sealed in a container and can be preserved for a long time at room temperature, is called canned food, also called canned food for short.
