The main role of vacuum packaging is to remove oxygen to help prevent food spoilage. The principle is relatively simple. The food going bad and decayed is mainly caused by the activity of microorganisms, and most microorganisms (such as molds and yeasts) need the oxygen to survive. Vacuum packaging takes this principle to remove oxygen from the packaging bag and food cells, to make the microorganisms to lose their living environment. The experiment proves that when the oxygen concentration in the packaging bag is ≤1%, the growth and reproduction speed of microorganisms will decrease sharply. When the oxygen concentration is ≤0.5%, most microorganisms will be inhibited and stop breeding. (Note: Vacuum packaging cannot inhibit the deterioration and discoloration of food caused by the proliferation of anaerobic bacteria and enzyme reactions, so it needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt Marinated, etc.)
