Onion cold storage fresh-keeping storage method

　　Onion is a common vegetable with a long shelf life, but appropriate methods need to be taken during storage to extend its shelf life. Cold storage is one of the ideal environments for onion storage. The following will introduce the relevant content of onion cold storage fresh-keeping storage methods:

　　1. Temperature control

　　Onions are best stored in a low temperature environment, and the temperature is generally recommended to be between 0°C and 4°C. By accurately controlling the temperature of the cold storage, the shelf life of onions can be extended.

　　2. Humidity regulation

　　Onions have high requirements for humidity, and the appropriate humidity range is 65% to 70%. Maintaining an appropriate humidity level in the cold storage can reduce the water loss of onions and extend their shelf life.

　　3. Ventilation and preservation

　　Good ventilation can effectively remove carbon dioxide and ethylene gas inside the cold storage, slow down the metabolism of onions, and extend the shelf life. At the same time, ventilation also helps to maintain the humidity balance inside the cold storage.

　　4. Moisture-proof treatment

　　Onions are easily affected by moisture and rot, so attention should be paid to moisture-proof treatment. When storing onions, use packaging materials or mesh bags with good air permeability to avoid direct contact with the ground to prevent moisture intrusion.

　　5. Partitioned storage

　　Depending on the type and maturity of onions, onions can be stored in cold storage in partitions. Separating onions with higher freshness from mature onions is conducive to extending the shelf life of fresh onions.

　　6. Regular inspection

　　Regularly check the storage status of onions and remove rotten or deteriorated onions in time to prevent rotten onions from affecting healthy onions around them.

　　The above fresh-keeping storage methods can effectively extend the shelf life of onions and maintain the freshness and taste of onions. As an ideal storage environment, cold storage provides good conditions for the long-term storage of onions. During the storage of onion cold storage, enterprises should strictly implement the above methods to ensure product quality and market competitiveness.
