The function of food vacuum packaging equipment in food packaging

Food vacuum packaging equipment is mainly to protect the safety of food and provide better production, so what role does it play in the process of food packaging? First of all, the working principle of food vacuum packaging equipment is that the equipment is put into the packaging bag of the package through the air extraction nozzle, and then the air is evacuated After the vacuum degree is predetermined, nitrogen or other mixed gases are filled in, and then the sealing process is completed
In fact, it is not so simple We all know that the main purpose of vacuum packaging is to remove oxygen, so as to prevent food from spoiling The principle is also very simple, which is to use the principle that the survival of microorganisms requires oxygen As long as the oxygen in the packaging bags and food cells is pumped out, the microorganisms will lose their living environment, which is good To extend the date of deterioration of the food
In addition, the vacuum deaeration method is used in the vacuum packaging equipment of food In addition to inhibiting the growth and propagation of microorganisms, the other important function is to prevent the oxidation of food For example, there are a large number of unsaturated fatty acids in the oil food If they are oxidized by oxygen, they will make the food taste and deteriorate In addition, the oxidation can also cause vitamin A and C Thus, the unstable substances in food pigment will also be affected by oxygen, making the color dark Therefore, deoxidization can effectively prevent food deterioration Food vacuum packaging equipment In addition to vacuum removal, vacuum inflatable packaging can also be used In addition to the functions of deoxidization and quality assurance, vacuum packaging mainly has the functions of pressure resistance, air blocking and fresh-keeping, which can more effectively keep the original color, fragrance, taste, shape and nutritional value of food for a long time In addition, many foods are not suitable for vacuum packaging and must use vacuum inflatable packaging 。
