How to make canned fruits

To know how cans achieve the effect of long-term food storage, you must first know what causes food spoilage. Microorganisms will breed and multiply in food. They continue to decompose the nutrients in food, causing the composition of the food to change and the food to deteriorate. Therefore, during the production process, you can retain part of the sugar water or drain the water in the can, and add industry at the same time. Additives specified in the standard to preserve freshness and prevent corrosion.
Therefore, cans generally work together in three ways to prevent food spoilage:
Sterilize
Whether it is food or canned food, it needs to be sterilized. After the bacteria and bacterial spores are eliminated, there will be no more bacteria to reproduce. However, it is unlikely to eliminate them all. What can be achieved is basic sterilization, so as to extend the food preservation time as much as possible.
seal
Dust in the air also contains a large number of bacteria and bacterial spores. Bacterial spores are like tree seeds, which are very durable and can float in the wind. So the cans are vacuum sealed.
