The storage and preservation of agricultural products has always been a headache for producers. The storage of agricultural products generally requires a moderate temperature, not too wet, and protected from light. In particular, some agricultural products with poor storage conditions, such as ripe bananas and tomatoes, require 12v car refrigerator factory not only low temperatures but also proper humidity to keep them fresh. The storage and preservation methods of agricultural products are as follows.

1. Refrigeration - cold storage
Low-temperature cold storage can reduce the respiration intensity of agricultural products, reduce water loss, and inhibit the growth of microorganisms. It can delay the activity of microorganisms and inhibit the activity of enzymes, thereby weakening the physiological and chemical changes of agricultural products during storage and maintaining their due quality. This storage method is characterized by good effect, but high cost.

2. Drying or dehydration
There are two kinds of natural drying and artificial drying. The purpose of drying is to reduce the humidity of the storage environment and the agricultural products themselves, eliminate the conditions for the growth and reproduction of microorganisms, and prevent the agricultural products from becoming moldy. The physiological activity of dry agricultural products has been reduced to a very low level, which can effectively inhibit the activity of microorganisms and is suitable for long-term storage.

3. Control the gas in the storage environment
Changing the concentration of respiratory gases in the storage environment can inhibit the respiration and other metabolic reactions of agricultural products. With the development of the times and the progress of the country, the storage and preservation technology of agricultural products is also constantly developing, such as the current mature cold storage. The day when people eat fresh fruits and vegetables every day is coming.
