The principle of modified atmosphere storage and fresh-keeping technology:

Oxygen accounts for 20.9% of normal atmospheric gas composition, and 0.03% for carbon dioxide, and modified atmosphere storage will change the content of oxygen and carbon dioxide in the storage environment. Among them, the content of oxygen is reduced to 2% -5%, and the content of carbon dioxide is increased to 2% -5%.

In addition to the use of low-oxygen and high-carbon dioxide gas conditions, the modified atmosphere storage and preservation technology also uses low-temperature storage. Fruits and vegetables in such a storage environment can maintain their freshness as long as possible and reduce the quality loss caused by respiration. After picking fruits and vegetables, they will still absorb oxygen from the atmospheric environment, release carbon dioxide, and produce a certain amount of water and release heat, that is, they are still breathing.

This respiration will decompose and consume nutrients in fruits and vegetables, resulting in reduced quality. To reduce the deterioration of the quality of fruits and vegetables caused by respiration, the key is to weaken their respiration and change the gas composition in the storage environment of fruits and vegetables to achieve this goal.

Ethylene can accelerate the ripening of fruits and vegetables, and is often used as a ripening agent. It is also an important reason for the post-ripening and aging of fruits and vegetables. Reducing the ethylene gas content in the storage environment can effectively delay the after-ripening and aging of fruits and vegetables, and prolong the storage time of fruits and vegetables.

The low-oxygen and high-carbon dioxide gas environment created by modified atmosphere storage can inhibit the biosynthesis of ethylene and avoid the degradation of fruits and vegetables due to ethylene accumulation. The low-oxygen, high-carbon dioxide environment and low-temperature environment under controlled atmosphere storage can also inhibit the growth of aerobic and mesophilic microorganisms, reducing the spoilage and deterioration of fruits and vegetables caused by microorganisms.

At the same time, the modified atmosphere storage environment will also inhibit the activity of certain enzymes, such as succinate dehydrogenase, cytochrome oxidase, etc., thereby delaying the degradation of fruits and vegetables caused by enzymatic reactions.

Why choose modified atmosphere packaging MAP

• Reduce product deterioration and extend the shelf life

• Reduce the need for artificial preservatives, food safety

• More natural preservation method, using only gas

• Rationalize logistics and centralized production

• Compatible marketable packaging can be used

• Has a good appearance on the shelf
