Be careful when purchasing vacuum packaged food

source:Industry News release time:2024-03-26 Hits:    

First, observe the bulging bag

Whether the bag is bulging or not is the most intuitive and convenient way for consumers to judge whether food vacuum packaging has deteriorated.

According to common sense in physics, under normal circumstances, the air pressure inside the packaged food bag should be consistent with the outside world or less than the outside world after vacuuming. If the bag bulges, it means that the air pressure inside the bag is higher than the outside world, which means that new air pressure has been produced in the sealed packaging bag. Gases, these gases are the metabolites produced by the massive reproduction of microorganisms, because the metabolites of a small amount of microorganisms are not enough to expand the bag. Most of the bacteria or molds that may cause food spoilage (lactobacillus, yeast, Aerobacillus aerogenes, Bacillus polymyxa, Aspergillus, etc., hundreds of species) will produce a large amount of gas during the process of decomposing protein and sugar in food. Such as carbon dioxide, hydrogen sulfide, ammonia, alkanes, etc. It is these gases that "blow" the packaging bag into a balloon. During the sterilization process of food before packaging, microorganisms and buds have not been completely killed. After packaging is completed, microorganisms multiply in large numbers and become corrupted, which naturally causes the problem of bulging packaging bags.

The second is to smell

When purchasing vacuum-packaged food, do not use the aroma of the food as a criterion. If the food smell overflows outside the package, it means that the vacuum package itself is no longer vacuum and there is air leakage. This means that bacteria can also "flow" freely.

The third is to check the identification

When you get a food package, you must first check whether its production license, SC code, production company, and ingredient list are complete. These certificates are like "ID cards" for food. Behind the certificates are the "past and present lives" of the food, where it comes from and where it has been.

The "Food Safety Law" clearly stipulates that the food production license number should be marked on food packaging. The number is composed of the letters "SC" plus 14 Arabic numerals. The "SC" code represents the company's unique license code, which can realize the traceability of food.

Fourth, strictly pay attention to the shelf life of food

Food approaching its shelf life does not mean it is harmful, but the color and nutrition of the food will decrease. After opening the vacuum packaged food, it should be eaten as soon as possible and should not be stored in the refrigerator. When purchasing "buy one, get one free" food, pay attention to the production date and shelf life of the bundled products.

According to the Economic Daily-China Economic Network Life Channel, vacuum packaging, also called decompression packaging, is to extract all the air in the packaging container and seal it, maintaining the bag in a highly decompressed state. The sparse air is equivalent to a hypoxic effect, making microorganisms unable to Living conditions to achieve the purpose of fresh fruit and no disease or rot.

In addition to the function of oxygen removal and quality preservation, the main function of vacuum inflatable packaging is to resist pressure, block air, and preserve freshness. It can more effectively maintain the original color, aroma, taste, shape, and texture of food for a long time. Nutritional value.
