Meat is one of the foods that people often eat, but because the shelf life of meat is relatively short, we can't store too much. In order to extend the shelf life of meat, more and more people use vacuum sealed, but how long does vacuum sealed meat last at room temperature?

In general, vacuum sealed meat can be stored for 15 days at room temperature, if stored in a frozen environment, it will be stored for a longer time.

The packaging method is to extract all the air in the packaging container, and then seal, so that the bag is under a state of high decompression, the air is scarce, and the microorganisms have no living conditions, thereby achieving the effect of keeping fresh and preventing decay.

The main function of vacuum packaging is to remove oxygen, which is beneficial to prevent food spoilage. The principle is also relatively simple, because the deterioration of food mold is mainly caused by the activity of microorganisms, and the survival of most microorganisms requires oxygen. Vacuum packaging is based on this principle. The oxygen in the package and in the food cells is removed, so that the micro-objects lose the "environment of survival."

Further, since fats and oils contain a large amount of unsaturated fatty acids, they are oxidized by the action of oxygen, and the food is degraded and deteriorated. In addition, oxidation also causes loss of vitamin A and vitamin C, and unstable substances in the food coloring matter are subjected to oxygen to darken the color. Therefore, oxygen scavenging can effectively prevent food from spoiling and maintain its color, aroma, taste and nutritional value.

For the above reasons, the vacuum sealed meat has a longer storage time than the ordinary storage method, but the storage time is different due to the different types of meat.
