What Is The Principle Of Canned Food Storage?

After the can is sterilized, the microorganisms inside are basically killed, so there is no need to use other additives, and the shelf life is quite long.
He was inspired by the fact that food sealed in glass containers would not spoil easily if properly heated. Therefore, Appel responded to the government's reward and conducted specialized research on food preservation methods.
Food spoilage is often the result of microbial activity and reproduction in nature, which promotes the decomposition of food. Canned food is a kind of food that can be stored for a long time by processing, sealing and sterilizing food raw materials. If the sealing performance of the container is poor, the sterilized food will be contaminated by microorganisms again and cause spoilage.
Therefore, the container must have very good sealing performance to ensure that the food can be isolated from the outside air after sterilization, prevent contamination by external microorganisms, and prevent deterioration, so that the food can be stored for a long time without deterioration.
