Modified Atmosphere Storage (MAS) can maintain the crispness of fruits and vegetables. After leaving the storage, the fruits and vegetables can meet the storage requirements for moisture content, vitamin C, sugar content, acidity, firmness, color, and weight, allowing for higher-quality produce to be supplied to the market. The use of micro-computer-controlled gas regulation methods in MAS achieves preservation effects by reducing oxygen in the air andCO₂Adjust the concentration to the required ratio for fruits and vegetables. On the basis of a high-temperature cold storage for preservation, an additional controlled atmosphere control system is added. By utilizing the combined effect of temperature and controlled oxygen content, it inhibits the post-harvest respiratory state of fruits and vegetables. The controlled atmosphere storage is widely applicable: extensively used for the preservation and storage of various vegetables, flowers, fruits, seedlings, etc., in both southern and northern regions.
