The Main Effect Of The Vacuum Bag

Oct 11, 2017

The main role of the vacuum bag bag: Shen Kai packaging vacuum bag is the main role in the oxygen, in order to help prevent food deterioration, the principle is relatively simple, due to food mold rot deterioration caused by microbial activity, and most microbes Mold and yeast) is the need for oxygen, and vacuum packaging is the use of this principle, the bags and food cells within the oxygen removed, so that the loss of micro-material "living environment."Vacuum Bag

Experiments show that when the oxygen concentration in the bag is less than or equal to 1%, the growth and reproduction speed of the microorganism decreases sharply. When the oxygen concentration is less than or equal to 0.5%, most microorganisms will be inhibited and stop breeding. (Note: Vacuum packaging can not inhibit the proliferation of anaerobic bacteria and enzyme reactions caused by food deterioration and discoloration, and therefore need to be combined with other auxiliary methods, such as cold storage, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt Pickled, etc.)Vacuum Bag Vacuum deaerator In addition to inhibiting the growth and reproduction of microorganisms, another important function is to prevent the oxidation of food, because the fat food contains a large number of unsaturated fatty acids, the role of oxygen and oxidation, so that food taste, deterioration, in addition, Vitamin A and C loss, food pigment in the unstable material by the role of oxygen, so that the color darkens. Therefore, the oxygen can effectively prevent food deterioration, to maintain its color, smell, taste and nutritional value.Vacuum Bag After the food is vacuum-filled, the inflatable pressure in the bag is greater than the atmospheric pressure outside the bag, which can effectively prevent the deformation of the food from crushing and does not affect the appearance and printing decoration of the bag. Vacuum inflatable packaging in a vacuum and then filled with nitrogen, carbon dioxide, oxygen, a single gas or two or three kinds of gas mixture. The nitrogen is an inert gas, from the filling effect, so that the bag to maintain a positive pressure to prevent the bag outside the air into the bag, the food play a protective role.Vacuum Bag
