What is the effect of aluminum foil vacuum packaging bags on food?
The application of aluminum foil vacuum packaging is becoming more and more widespread. Vacuum packaging is widespread in the food industry. Various types of aluminum foil food vacuum packaging abound in people's lives. So, what is the use of food vacuum packaging bags? Better Packaging said that the aluminum foil food vacuum packaging bag is to reduce the oxygen content in the package, prevent the mold and rot of the packaged food, maintain the color and fragrance of the food, and extend the shelf life.
The role of aluminum foil food vacuum packaging bags is mainly to remove oxygen to help prevent food deterioration. The principle is also relatively simple. Because food mildew and deterioration are mainly caused by the activities of microorganisms, most of the microorganisms need oxygen to survive, and vacuum Packaging uses this principle to extract oxygen from the food cells in the packaging bag, so that microorganisms lose their living environment, and most microorganisms are inhibited and stop reproducing.
Another important function of aluminum foil vacuum packaging bags is Fangzi food oxidation. Because fats and oils contain a large amount of unsaturated fatty acids, they are oxidized by the action of oxygen, which makes the food taste and deteriorate. In addition, oxidation can also cause the loss of vitamin A and C. The unstable substances in food pigments are affected by oxygen to darken the color.
