The potential of dynamic controlled atmospheres (DCA) as a non-chemical treatment for maintaining the postharvest quality of apples during long-term cold storage has been an interest of researchers for decades. This article reviews the recent developments in DCA technology for storage of apples. The effects of DCA on physiological disorders, physico-chemical and sensory quality are discussed. Moreover, negative effects associated with DCA technology are also discussed. The study has shown that DCA maintains apple postharvest quality by reducing respiration rate and ethylene production. Ethylene-mediated physiological disorders such as superficial scald are compley suppressed by DCA storage. However, the effect of DCA on bitter pit incidence needs further investigation. The review also showed that fruit firmness and colour retention is considerable high in DCA stored apples. Although DCA maintains both the physico-chemical and organoleptic quality of apples, the high risk of CO2 and low O2 injury in DCA stored fruit remains a concern. Further research is required to refine and improve the DCA technology in order to minimize the risk of CO2 and low O2 injury during longterm storage.
幾十年來, 蘋果在收獲后長期冷藏過程中的品質一直是研究人員研究重點。這本文綜述了蘋果儲 DCA 技術的進展。DCA 對生理的影響因素, 理化指標和感官質量進行了討論。及相關的負面影響并對 DCA 技術進行了討論。研究表明, DCA 通過降低呼吸速率和乙烯產量。乙烯介導的生理疾病, 如淺表燙傷被 DCA 存儲*抑制。然而, DCA 對苦坑發生率的影響還有待進一步的研究，研究還表明, 在 DCA 中, 蘋果果實的硬度和保留率相當高。盡管 DCA 同時保持了蘋果的理化指標和感官質量, 但蘋果存的高風險。DCA 儲存水果中的 CO2 和低 O2 損傷仍然是一個值得關注的問題。需要進一步的研究來完善和改進，DCA 技術, 以大限度地降低長期儲存過程中 CO2 和低 O2 損傷的風險。
