[0002] As we all know, the reason why fruits and vegetables gradually become soft after being harvested is that they produce ethylene, a natural ripening agent, through their own metabolism. It is a plant hormone that can promote the respiration of fruits and vegetables and accelerate maturity and aging. Some people call it "ripening hormone". Especially in closed fruit and vegetable storage packaging or space, ethylene gas gradually accumulates with the extension of storage period, thus producing a self-ripening effect on fruits and vegetables, and continues to circulate, affecting the normal metabolism of fruits and vegetables, promoting the aging process of fruits and vegetables, increasing decay, and shortening the storage period of fruits and vegetables. Therefore, controlling the ethylene content in the storage warehouse is very important to ensure the quality of fruits and vegetables, especially for those fruits and vegetables that are very sensitive to ethylene, such as kiwis, persimmons, apples, etc., the ethylene in the storage environment must be removed to below the threshold.
