Mechanism Of Vacuum Packaging Machine

- Nov 08, 2017-

The main role of vacuum packaging is to remove oxygen, in order to help prevent food spoilage, its principle is also relatively simple, because the food mildew spoilage mainly by the activity of microorganisms, and most microorganisms (such as mold and yeast) to survive the need for oxygen, and vacuum packaging is to use this principle, the packaging bag and food cells inside the oxygen to smoke out, To make microbes lose their living environment. The experiment shows that when the oxygen concentration in the bag is ≤1%, the growth and reproduction rate of microorganism drops sharply, and when oxygen concentration ≤0.5%, most microorganisms will be inhibited to stop breeding. (Note: Vacuum packaging can not inhibit the reproduction of anaerobic bacteria and enzyme-induced food spoilage and discoloration, and therefore need to be combined with other ancillary methods, such as refrigeration, frozen, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling and so on. )
