Product Detail

Controlled atmosphere storage technology is ahead of the traditional technology of chilled, frozen, most crucial is whether the difference is the real meaning of "fresh". Compared to traditional chilled, frozen, fresh, and modified atmosphere fresh-keeping industry is another alternative of innovation. Traditional chilled, frozen, Vault is lowering the temperature below the freezing point, by inhibiting microbial activity to fresh fruit. Frozen food thawed in advance at the time, so the stored product freshness, quality, taste and nutrition has a lot of damage, especially the stored product from chilled, frozen, environment later maturity will speed up the process of decay must be consumed as soon as possible. This is because the volume of ice is greater when the cells contained within the water freezes at a low temperature, it will make the cell wall damage, death, heated life characteristics of melts cells are also not available, so compared with the living State of preservation has a great deal of difference. Gas adjustable preservation is artificial control gas in the nitrogen, and oxygen, and carbon dioxide, and vinyl, components proportions, and humidity, and temperature (frozen tipping point above) and the pressure, through inhibit storage real cell of breathing volume to delay its metabolism process, makes of in near dormant state, and not cell death State, thus can more long time of keep was storage real of texture, and color, and taste, and nutrition, of basic not variable, then reached long-term preservation of effect. Even if it is stored away from the atmosphere storage environment, the cell life activity will remain normal metabolic rates in a natural environment, will not mature quickly corruption. Controlled atmosphere storage,Hereinafter referred to as "CA" store is an advanced fruit and vegetable fresh-keeping and storage methods. Is essentially a controlled atmosphere storage and fresh-keeping based on gas composition adjustment, based on storage temperature, humidity and carbon dioxide in the environment, control conditions such as concentration and the concentration of ethylene oxide, inhibited respiration of fruits and vegetables, slow down metabolic processes than ordinary cold can better preserve the freshness of fruits and vegetables, and commercial, to extend the storage period and the sale shelf.


Controlled atmosphere storage can do to maximise vegetable storage most appropriate conditions, the effect is as follows:


1 Suppress respiration, reduce consumption of organic matter, keeping excellent flavor and aroma.


2 inhibit evaporation, keeping freshness of fruits and vegetables.


3 suppression breeds propagation of pathogens, controlling physiological disease occurrence and reduce fruit decay rate.


4 inhibition of ripening enzymes activity, inhibiting ethylene production, delaying ripening and senescence, keep fruit firmness, has a long shelf life.
