Mopan persimmon was used as the raw material.The effect of 1-MCP and vacuum packaging on physiology and crispiness-keeping of incomplete de-astringency persimmons under room temperature were investigated.Results showed that 1-MCP combined with individual vacuum packaging effectively inhibited the decline of fruit firmness,respiration rate and cell membrane permeability.It also promoted the change of the soluble tannin into unsolvable tannin.The soluble tannin content dropped to 0.03% at 7d and the firmness was 18.63 kg/cm2;at 42 d the firmness was 17.52 kg/cm2.The the control persimmon group was softened completely at the 21st day with soluble tannin content of 0.02.Therefore,1-MCP combined with individual vacuum packaging can effectively prolonged storage time for 21 days.
