Automatic vacuum packaging machine deoxidation and antibacterial process

How to eliminate oxygen and bacteria in automatic vacuum packaging machine , in addition to inhibiting the growth and reproduction of microorganisms, vacuum deoxidation, another important function is to prevent food oxidation, because oily foods contain a large amount of unsaturated fatty acids, which are oxidized by oxygen. Make food taste and deterioration.

Oxidation also loses vitamins. In addition to inhibiting the growth and reproduction of microorganisms, vacuum deoxidation in food pigments is another important function to prevent food oxidation. Because oils and fats contain a large amount of unsaturated fatty acids, they are oxidized by oxygen to make foods taste. Deterioration, in addition, oxidation also loss of vitamins, unstable substances in food pigments are affected by oxygen, and the color becomes dark.

Deoxygenation can effectively prevent food from spoiling and maintain its color, aroma, taste and nutritional value. It has great commercial value. The main function of the automatic vacuum packaging machine inflatable packaging is vacuum packaging, which has the functions of anti-oxidation, preservation and preservation. It mainly has the functions of compression resistance, shatterproof, gas barrier and preservation, which can be more effective. The ground maintains the original color, aroma, taste, shape and nutritional value of the food for a long time.

There are many foods that are not suitable for vacuum packaging and must be vacuum-filled. Such as potato chips and so on. After the food is vacuum-inflated and packaged, the inflation pressure in the packaging bag is stronger than the atmospheric pressure outside the packaging bag, which can effectively prevent the food from being crushed and deformed without affecting the appearance of the packaging bag. The vacuum inflated package is filled with nitrogen, carbon dioxide, oxygen single gas or a mixture of two or three gases after vacuum.

1. Nitrogen is an inert gas that acts as a filling to maintain a positive pressure inside the bag to prevent the air outside the bag from entering the bag and to protect the food.

2. Oxygen inhibits the growth and reproduction of anaerobic bacteria, keeps the freshness and color of fruits and vegetables, and high-concentration oxygen keeps fresh meat fresh red.

3, carbon oxide can be dissolved in various types of fat or water, lead to weak acid carbonic acid, inhibit the activity of microorganisms such as mold, spoilage bacteria.
