The role of vacuum sealing machine

The main function of vacuum packaging is to remove oxygen to help prevent food from spoiling. The principle is also relatively simple. The mold and spoilage of food are mainly caused by the activities of microorganisms, and most microorganisms (such as molds and yeasts) need oxygen to survive. Yes, and vacuum packaging uses this principle to extract oxygen in the packaging bag and food cells, so that microorganisms lose their living environment. Experiments have proved that when the oxygen concentration in the packaging bag is ≤1%, the growth and reproduction speed of microorganisms will drop sharply. When the oxygen concentration is ≤0.5%, most microorganisms will be inhibited and stop reproducing. (Note: Vacuum packaging cannot inhibit the growth of anaerobic bacteria and the deterioration and discoloration of food caused by enzyme reactions. Therefore, it must be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt Marinated etc.)
