Vegetable fresh-keeping cold storage

Vegetable fresh-keeping cold storage is a storage method that inhibits the activity of microorganisms and enzymes and prolongs the long-term storage period of fruits and vegetables. Fresh-keeping cold storage technology is the main way for modern fruits and vegetables to be kept fresh at low temperature. The fresh-keeping temperature range of fruits and vegetables is 0℃～15℃. Fresh-keeping storage can reduce the incidence of pathogenic bacteria and the decay rate of fruits, and can also slow down the respiration and metabolism of fruits, so as to prevent decay and prolong the storage period. The emergence of modern refrigeration machinery enables the preservation technology to be carried out after rapid freezing, which greatly improves the quality of fresh-keeping and storage of fruits and vegetables.

The air-conditioned fresh-keeping warehouse is a relatively advanced fresh-keeping facility for fruits and vegetables at home and abroad. It can not only adjust the temperature and humidity in the warehouse, but also control the content of oxygen, carbon dioxide and other gases in the warehouse, so that the fruits and vegetables in the warehouse are in a dormant state, and the original quality is still maintained after leaving the warehouse.

1. Extend the storage period of fruits and vegetables, which is generally 0.5 times to 1 times longer than that of ordinary refrigerators. When they are stored to the most expensive price, they can be sold on the market, and the highest profit can be obtained.

2. It can keep fruits and vegetables fresh and crisp. After leaving the warehouse, the moisture, vitamin C content, sugar, acidity, hardness, color and weight of the fruits and vegetables can meet the storage requirements. The fruit is crispy and the vegetables are tender green, which is almost the same as the newly picked shape, which can provide high-quality fruits and vegetables to the market.

3. It can inhibit the occurrence of diseases and insect pests of fruits and vegetables, and minimize the weight loss of fruits and vegetables and the loss of diseases and insect pests.

4. The shelf period of fruits and vegetables out of the warehouse can be extended to 21 days to 28 days, while the shelf life of fruits and vegetables in ordinary refrigerators can only last for about 7 days before they deteriorate. The so-called modified atmosphere preservation is to achieve the effect of preservation through the gas adjustment method. Gas regulation is to reduce the oxygen concentration in the air from 21% to 3%. 5%, that is, the fresh-keeping warehouse is based on the high-temperature cold storage, plus a set of air-conditioning system, which uses the combined effect of temperature and oxygen content control to inhibit the post-harvest respiration of fruits and vegetables.
