Canned food doesn’t need preservatives at all

The long shelf life of cans is not because of preservatives but because of the strict production process. According to the Canned Food Alliance, the average crunch will maintain good flavor for at least two years after processing, and the taste of the food tin cans will last for more than two years.

The high temperature destroys the microorganisms and inactivated enzymes in the can, and the vacuum seal after the heating stops the outside microorganisms from coming into contact with the food in the can, so it do not need preservatives to prevent  food  from spoiling and rotting.

This is why the canned food we eat  today can be preserved  for a long time without preservatives.

  4. Exhaust: exhaust helps to prevent the growth and propagation of aerobic bacteria and yeast, and is conducive to the preservation of food color, aroma, taste and nutrients.
  5. Sealing: Different containers should be sealed in different ways.
  6. Sterilization: There are many ways to sterilize cans, such as heating sterilization, flame sterilization, radiation sterilization and high pressure sterilization, etc., the most widely used is heating sterilization.
