The work aims to explore the effects of 1-MCP combined with MAP on shelf quality of deastringent Gongcheng Yue persimmon under ambient temperature after different cold storage. This experiment used no treatment (CK), modified atmosphere packaging (MAP), 1-MCP treatment and 1-MCP combined with modified atmosphere packaging (1-MCP+MAP) to treat the persimmons that carried out deastringency treatment after not cold storage, different cold storage periods(15 d and 30 d), effects of different treatments on persimmon fruit chromatism aberration ΔE, total soluble solids content, respiration intensity, ethylene production rate, firmness, ascorbic acid content and antioxidant capacity indexes of persimmon fruit during shelf life after different cold storage periods were studied. Along with the lengthen of cold storage periods, fruit chromatism aberration ΔE increased gradually, and fruit TA content, TSS content, flesh firmness, ascorbic acid content, SOD activity and T-AOC activity decreased gradually. At cold storage of 30 d, fruit chromatism aberration ΔE increased significantly(P<0.05), and ascorbic acid content, SOD activity decreased significantly(P<0.05), shelf life cut down 6 d. During shelf life without cold storage, the treatment methods of 1-MCP, MAP, 1-MCP+MAP could postpone the change of chromatism aberration ΔE, reduce the losses of TA content, control respiration intensity and ethylene production rate, maintain flesh firmness and ascorbic acid content, SOD activity and T-AOC activity, among that 1-MCP+MAP was the best, 1-MCP was the second. The treatment method of 1-MCP combined with MAP could persimmon fruit maintain original peel color, lessen nutrient substance losses, slow down respiratory metabolism, keep flesh firmness and antioxidant capacity, and the shorter the cold storage period, the better the effect.
