Have you noticed? Nowadays vacuum packing is more and more popular. Do you know why do we vacuum pack food?
First, we need to know what a vacuum package is. Vacuum packaging, also known as decompression packaging, is to take all air out of the packaging container and seal it, keeping the bag in a highly decompression state. The lack of air in the vacuum packaging environment is equivalent to the effect of low oxygen. This environment makes the microorganism have no living conditions, so as to achieve the goal of fresh fruit without disease and rot. At present, there are vacuum packaging in plastic bags, aluminum foil vacuum packaging, glassware, plastic and its composite materials vacuum packaging. Customers can choose packing materials according to the item type. However, as fruit is fresh food, which is still undergoing respiration, high degree of hypoxia can cause physiological diseases. Therefore, there is less use of vacuum packaging for fruit products. So, why do we vacuum pack food?

The main function of vacuum packaging is deoxygenation. The principle of vacuum packaging is also relatively simple. Why do we vacuum pack food? This is because food moldy deterioration is mainly caused by the activities of microorganisms, while the survival of most microorganisms requires oxygen. The vacuum packaging removes oxygen from the packaging and the food cells, so that microobjects lose their living environment, which can effectively prevent food deterioration. When food is exposed to air, oxygen in the air also reacts with the fat in the food, making the food taste very different.
Summarize why do we vacuum pack food.

1.Vacuum packaging is to reduce the oxygen content in the packaging, prevent mold rot and deterioration of packaged food, maintain food color and flavor, and extend the shelf life.
2. Compared with ordinary packaging methods, vacuum packaging reduces the space occupied by articles, and has the advantages of moisture-proof, dust-proof and bacteria-proof, making the transportation of clothing articles more convenient.
3. The possibility of loss caused by some accidents has been greatly reduced.

One variant of vacuum packaging is the inflatable packaging. The main function of the air-filled packaging is not only the function of oxygen preservation, but also the function of anti-pressure, anti-gas and fresh-keeping, which can effectively keep the original color, aroma, taste, shape and nutritional value of food for a long time. In addition, a lot of food should not be vacuum-packed, but must be air-filled. Such as crunchy fragile food, easy to agglomerate food, easy to deform oil food, sharp Angle or high hardness will puncture the package of food.
