Modified atmosphere packaging machine is an advanced packaging equipment that extends the shelf life and maintains food quality by adjusting the gas composition inside the packaging. It plays an important role in food processing and sales with its unique modified atmosphere preservation technology.

The working principle of the modified atmosphere packaging machine is based on the impact of different gases on food preservation. Generally speaking, the gas inside the packaging is mainly composed of nitrogen, oxygen, and carbon dioxide. Nitrogen is an inert gas that can fill packaging spaces, prevent food from being squeezed and deformed, and inhibit the growth of microorganisms; Oxygen can maintain the color and flavor of food, but excessive oxygen content can accelerate the oxidation and spoilage of food; Carbon dioxide can inhibit the growth of bacteria and mold. The modified atmosphere packaging machine creates a suitable preservation environment for food by precisely controlling the ratio of these three gases.

During the packaging process, the modified atmosphere packaging machine first extracts the air inside the packaging, then fills it with a mixture of nitrogen, oxygen, and carbon dioxide according to the preset gas ratio, and finally seals the packaging. In this way, food is placed in an environment with low oxygen, high nitrogen, and appropriate carbon dioxide content inside the packaging, greatly slowing down the growth of microorganisms and the oxidation rate of the food, thereby extending the shelf life of the food.

The modified atmosphere packaging machine is suitable for packaging various foods, such as fresh meat, seafood, fruits, vegetables, pastries, etc. For fresh meat, modified atmosphere packaging can maintain the color and tenderness of the meat, extending its shelf life; For fruits and vegetables, modified atmosphere packaging can inhibit their respiration, reduce water loss, and maintain their freshness and taste; For pastries, modified atmosphere packaging can prevent oxidation and mold growth, and extend shelf life.

In food processing enterprises, modified atmosphere packaging machines are important equipment for enhancing product competitiveness. It can provide consumers with fresher and safer food, meeting their demand for high-quality food. Meanwhile, modified atmosphere packaging can also reduce food loss and lower the cost of enterprises.

In supermarkets and retail industries, food packaged in modified atmosphere packaging is more attractive to consumers' attention. Its good preservation effect can keep food fresh on the shelf for a long time, increasing consumers' desire to purchase.

The modified atmosphere packaging machine has become an important equipment in the field of food preservation due to its advanced modified atmosphere preservation technology, wide applicability, and good preservation effect, making positive contributions to the development of the food industry.
