Factors affecting product quality:

1, tin can rusted.

There are two main adverse changes in tin cans. One is the corrosion of the outer surface of the can, and the other is the corrosion of the inner wall of the can. The corrosion of the outer wall surface of the tank is mainly caused by excessive moisture in the air. When the corrosion is not serious, it has no effect on the contents of the can; In severe cases, it will cause perforation and air leakage in the tank wall, so that the food in the can will be spoiled.

Inner wall corrosion mainly refers to the result of chemical interaction between the inner wall of the can and the contents, which makes the coating on the inner wall of the can fall off, produces iron spots and makes the contents have a metallic taste; If the corrosion is serious and concentrated at one point, it will also cause perforation and air leakage, thus affecting the quality of canned food.

2. Acid corrosion of canned food

It refers to rancidity caused by bacterial contamination, but the surface of the can does not produce abnormal manifestations such as fat hearing and deformation. This can is not easy to distinguish from normal cans, and only after opening the can can can can it be identified by abnormal changes in smell and taste or rancid taste.
