The main function of vacuum packaging is oxygen dehuminar, which is conducive to preventing food deterioration. The principle is relatively simple. Because the deterioration of food mildew is mainly caused by microorganisms The vacuum packaging is to use this principle to remove the oxygen in the packaging bag and food cells, so that the microorganisms lost the "living environment" experiment to prove that when the oxygen concentration in the packaging bag ≤1%, the growth and the growth of microorganisms and the growth of microorganisms When the breeding speed decreases sharply, when the oxygen concentration is ≤0.5%, most microorganisms will be inhibited to stop breeding. (Note: Vacuum packaging cannot inhibit the deterioration and discoloration of foods caused by the reproduction of anaerobic bacteria and enzyme reactions, so it is necessary The auxiliary method is combined, such as refrigerated, quick -frozen, dehydration, high temperature sterilization, irradiated sterilization, microwave sterilization, salt and other.)
In addition to inhibiting the growth and reproduction of microorganisms in vacuum removal, another important function is to prevent food from oxidation. Because oil -fat foods contain a large amount of unsaturated fatty acids, oxygen -oxidized Vitamin A and C losses, the unstable substances in food pigments are used to darker the color. Therefore, oxygen removal can effectively prevent food from deteriorating, maintain its color, aroma, taste and nutritional value.
In addition to the oxygen and healing function of vacuum packaging, the main role of vacuum inflatable packaging also mainly has the effects of compressiveness, gas resistance, fresh -keeping, etc., which can more effectively maintain the original color, fragrance, shape and nutritional value of food for a long time. In addition, there are many foods that are not suitable for vacuum packaging and must be packaged in vacuum inflatable packaging. For example, crispy and fragile foods, easy to get pieces of food, easy to deformed oil foods, have sharp edges or high hardness. After the food is vacuum -inflated packaging, the inflatable pressure inside the packaging bag is stronger than the atmospheric pressure outside the packaging bag. It can effectively prevent the crushing and deformation of the food from being crushed and deformation.
Vacuum inflatable packaging is filled with nitrogen, carbon dioxide, oxygen single gases or 2-3 gas mixed gas after vacuum. Its nitrogen is an inert gas, which plays a positive pressure in the bag to prevent the air from outside the bag from entering the bag. Inside, it plays a protective effect on food. Its carbon dioxide can be stronger than various types of fat or water, causing acidic carbonic acid with weak acidity, and the activity of microorganisms such as inhibitory mold and corruption bacteria. , Keep fruits, fresh and color of vegetables, high concentration oxygen can keep fresh meat bright red.
