How does the air conditioning preservation technology of food nitrogen machine use nitrogen and other inert bacteriostatic gases

With the development of science and technology and the improvement of people's living standards, people's requirements for food preservation quality are also increasing. Air conditioning preservation storage technology refers to the use of inert antibacterial gases such as nitrogen and carbon dioxide to inhibit bacterial growth and reproduction, thereby delaying the metabolic process of storage cells, so as to maintain the freshness of the technology. Compared with other technology methods such as temperature control, water removal, adding food preservatives, ionization irradiation, etc., this type of food preservation technology has many advantages:

1. The use of inert gas to isolate the air, directly inhibit the growth and reproduction of bacteria, delay the metabolic process of food cells, can effectively extend the preservation time.

2. The temperature of the food preserved with nitrogen will not change, the water will not be lost, and the original nutrition, texture, color and taste of the food will be maintained to the greatest extent.

3. Nitrogen preservation without preservatives, no acidification, no temperature change, no radiation irradiation, safety and environmental protection, no pollution.

4. Nitrogen preservation technology is simple and feasible, low operating cost, and significant economic benefits.

5. The food after inflatable packaging is very convenient to transport, and it can also be very good to prevent extrusion, avoid food breaking and bonding. To maintain the appearance of food, shape and other advantages.
