Modified atmosphere storage uses low oxygen partial pressure and high carbon dioxide partial pressure to reduce the oxidation activity in biological tissues, inhibit the production of ethylene and effectively inhibit the respiratory intensity of fruits; Can keep the fruit quality, reduce the loss, greatly reduce the loss caused by freezing injury and physiological injury, and greatly improve the economic benefits. In addition, it can also control the growth and reproduction of fungi and prevent the harm of rats and the survival of insects.
However, high carbon dioxide and low oxygen partial pressure may promote abnormal metabolism of fruits and cause tissue damage. Some injuries are manifested as flesh browning, tissue disintegration and accumulation of some organic acids, low oxygen concentration, and many fruits produce odor or rot due to anaerobic respiration. Moreover, the one-time investment of modified atmosphere storage is high, and because different fruits need different gas conditions and temperature conditions, more warehouses are needed.
