The Inevitable Development Trend Of Vacuum Bag

Sep 25, 2017

     The main role of vacuum bag 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, The loss of "living environment" of micro-objects. The experimental results show that when the oxygen concentration in the bag is ≤1%, the growth and propagation rate of microorganism drops sharply, and the oxygen concentration ≤ 0.5%, most microorganisms will be inhibited to stop breeding.Vacuum Bag

    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.Vacuum Bag

    In addition to inhibiting the growth and reproduction of microorganisms, the other important function of vacuum oxygen removal is to prevent food oxidation, because the oil food contains a large number of unsaturated fatty acids, by the role of oxygen oxidation, so that food stale, spoilage, in addition, oxidation also makes vitamin A and C loss, food pigments in the unstable substances in the role of oxygen, so that the color dimming. Therefore, the removal of oxygen can effectively prevent food spoilage, maintain its color, aroma, taste and nutritional value.Vacuum Bag

    Vacuum inflatable packaging In the vacuum after filling into nitrogen, carbon dioxide, oxygen single gas or two or three of gases mixed gas. The nitrogen is inert gas, filling the bag, so that keep positive pressure in order to prevent outside the bag of air into the bag, the food play a protective role. Vacuum Bag

    Its carbon dioxide can dissolve in all kinds of fat or water, lead to acidic weak carbonic acid, inhibit mold, corrupt bacteria and other microorganisms activity. Its oxygen can inhibit the growth and reproduction of anaerobic bacteria, keep fruit, vegetables fresh and color, high concentration of oxygen to keep fresh meat in its bright red.Vacuum Bag
