Yiyongbengdai vacuum foil bag Main products: aluminum foil bag, vacuum bag, shielding bags, aluminum bags, board vacuum bags, cooking food vacuum bag, nylon vacuum bag, anti-static bags and other packaging materials, metal. The main role of the vacuum bag is oxygen, in order to help prevent food spoilage, the principle is relatively simple, mainly because of deterioration of food mold rot caused by microbial activity, but most microorganisms (such as yeast and mold) is needed oxygen for survival while this principle is the use of vacuum packaging, the packaging bag and food cells deprived of oxygen, so that the micro-material objects lose the "survival of the environment." Experimental results show: When the oxygen concentration packaging bags ≤1%, rate of growth and reproduction of microorganisms on a sharp decline in oxygen concentration ≤0.5%, most microorganisms will be inhibited and stop breeding. (Note: The vacuum packaging can not inhibit the propagation of food spoilage and discoloration caused by anaerobic bacteria and enzyme reactions, and therefore needs to be combined with other auxiliary methods, such as refrigerated, frozen, dehydrated, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt marinated, etc.) ?? vacuum oxygen in addition to inhibit microbial growth and reproduction, another important function is to prevent food oxidation, because fats and oils in foods rich in unsaturated fatty acids, the role of oxygen by oxidation, the food taste, metamorphism, in addition, an oxidation of vitamin A and C losses, the role of oxygen in food coloring by unstable substances, the color darker. Therefore, the oxygen can effectively prevent food spoilage, keep its color, smell, taste and nutritional value. Advisory way: 13862288812 / QQ: 136288258 http://www.ksqspack.com/
