The role of food vacuum bag

Abstract: the food is the main purpose of the vacuum packaging form a similar to the vacuum of space, reducing food and oxygen gas contact, slow food spoilage, mildew reaction, so as to extend the shelf life of food. Vacuum packing bag is a lot of food, especially meat products choose to use the bags, because after the food vacuum packaging can prolong the shelf life. So why vacuum packaging to enhance food shelf life? Which conditions to meet again? Vacuum packaging is how to operate? Food packaging bags after pumping air into vacuum state, constitute a similar vacuum space inside the bag. Food contact with air, oxygen, the opportunity is less, most of the food ingredients can react with oxygen, reaction to a certain extent, also the metamorphism, moldy. When the food and oxygen, less contact area is smaller, the speed of response is greatly reduced, which also makes food to prolong shelf life. Can through the above that the principle of vacuum packaging to extend the shelf life, reduce the contact food and oxygen, slow metamorphism, mildew reaction. So the bag heat sealing effect is better, better air tightness, so as to achieve a good vacuum effect. Lower oxygen transmittance and packaging material, high temperature resistant, Related to the packaging production) 。 Next to introduce the meat food vacuum packaging is how to operate: 1, the food to fill into the bag ( Usually for three edge sealing) 2, using the vacuum suction pump, 3, heat sealing, 4, sterilization, such as water, steam, high temperature furnace, ultraviolet. Then vacuum packaging is done. Vacuum packing bag is very extensive application in the food, in addition to the above said meat food, and grain food, drink tea food, dried fruit, nuts, processed foods such as all kinds of food of oxygen is sensitive, many will choose vacuum packing. Of course fragile, easy to deformation of the food is unfavorable choose vacuum bags. Tags: vacuum packing bag
