Modified atmosphere storage

Controlled atmosphere fresh-keeping storehouse is to artificially control the proportion of nitrogen, oxygen, carbon dioxide, ethylene and other components, humidity, temperature (above the freezing critical point) and air pressure in the gas, delay the metabolic process by inhibiting the respiration of storage cells, and make them in a near dormant state rather than cell death state, so as to maintain the texture of stored objects for a long time The color, taste and nutrition are basically unchanged, so as to achieve the effect of long-term preservation. Even if the fresh-keeping storage is removed from the modified atmosphere fresh-keeping environment, its cell life activities will still maintain the normal metabolic rate in the natural environment and will not mature and corrupt soon.

Characteristics of modified atmosphere fresh-keeping storehouse and cold storage fresh-keeping storehouse the key difference between the technology of modified atmosphere fresh-keeping storehouse and the traditional cold storage and freezing technology is whether or not

It is 'fresh' in the real sense. Compared with the traditional cold storage and freezing preservation, modified atmosphere preservation is an alternative innovation in the preservation industry. The traditional cold storage is to reduce the temperature below the freezing point and achieve the fresh-keeping effect by inhibiting the activities of microorganisms. When eating frozen food, it needs to be thawed first, so it will greatly damage the freshness, quality, taste and nutrition of the storage. In particular, after the storage is separated from the refrigerated and frozen environment, the process of maturity and corruption will be accelerated, so it must be eaten as soon as possible. This is because the volume of ice is larger than that of water. When the water contained in the cell forms ice at low temperature, its cell membrane wall will be damaged and die. After heating and melting, it does not have the life characteristics of the cell. Therefore, it is very different from the preservation in the living state. Controlled atmosphere preservation is to artificially control the proportion, humidity, temperature (above the freezing critical point) and air pressure of nitrogen, oxygen, carbon dioxide and ethylene in the gas, delay the metabolic process by inhibiting the respiration of storage cells, and make them in a near dormant state rather than cell death state, so as to maintain the texture, color and The taste and nutrition are basically unchanged, so as to achieve the effect of long-term preservation. Even if the fresh-keeping storage is removed from the modified atmosphere fresh-keeping environment, its cell life activities will still maintain the normal metabolic rate in the natural environment and will not mature and corrupt soon. Controlled atmosphere storage (CA) is an advanced new method for fresh-keeping and storage of fruits and vegetables. In essence, controlled atmosphere storage is to increase the regulation of gas composition on the basis of preservation. Through the control of temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment, it can inhibit the respiration of fruits and vegetables and delay the metabolic process. Compared with ordinary cold storage, it can better maintain the freshness and commercialization of fruits and vegetables and prolong the storage period and sales shelf life.
