The controlled atmosphere room is advanced in storage and preservation of fruits and vegetables currently. On the basis of cold storage, it regulates the gas composition. Through controlling storage environment in terms of temperature, humidity, concentration of oxygen, carbon dioxide and ethylene, etc., the respiration of vegetables and fruits can be inhibited, thus postponing the metabolic processes.
When stored in CA room, the fruits and vegetables can better keep freshness and marketability. This prolongs the storage period and shelf life of vegetables and fruits. Generally, the storage period of the CA storage system is 2 to 3 times longer than that of the common cold storage methods.
