The paper aims to study effects of 1-methylcyclopropene (1-MCP) treatment on quality of the cold chain preservation system of Gongchengyue persimmon after harvest. The postharvest Gongchengyue persimmon was treated through 1-MCP and compared with those without treatment, and then transferred to the whole process cold chain logistics transportation system to study the color difference (L and C), soluble solids (TSS), titratable Acid (TA), respiration rate, ethylene production rate, ascorbic acid (VC), soluble tannin, total phenol, pulp hardness, cellulase (CX), polygalacturonase (PG) and pectin esterase ( PE) changes in the preservation quality of the activity of persimmon fruit during different circulation stages, and compared with the control group. The storage periods of treatment groups A and B under the whole process of cold chain logistics preservation system were 49 d and 63 d respectively. Compared with normal temperature logistics, the storage period was extended by 27 d and 41 d, respectively. The change node for persimmon quality of treatment group A was stored for 21~42 d; the inflection points of respiratory, antioxidant and softening enzyme activities were 34, 21 and 21 d, respectively; and the basic circulation performance was lost at 49 d; the changed node of the 1-MCP treatment persimmon fruit quality during the storage period last from 49 d to 56 d; the effect on total phenol and PE was extremely significant (P<0.01); compared with treatment group A, the L , C , TA, respiratory intensity, Vc, tannin, total phenol, puncture, and PE enzyme activity of treatment group B were 1.19, 1.60, 40.93, 0.90, 1.33, 2.05, 3.12, 4.3, and 0.55 times higher, respectively. However, the effect on TSS content and peak respiratory intensity was not significant (P>0.05). The whole process of cold chain preservation system can maintain the sensory value of persimmon fruit, slow down the loss of nutrients, delay the peak of breathing, reduce the conversion of antioxidants and soften the related enzyme activities, among which 1-MCP treatment is the best. It is a good post-harvest storage and transportation program for Gongchengyue persimmon.
