Youyou sweet persimmons and 1-MCP cartridge bag(concentration of 1μL/L) were together placed in portable gas regulation preservation boxes and stored in accurate phase temperature.Two tests were performed at room temperature after storing for 30 d and 60 d to analysis the effects of microenvironment gas regulation on quality,physiology and volatile component of sweet persimmons.The result showed that compared with box-type gas regulation(TCK),microenvironment gas regulation with 1-MCP combined with box-type gas regulation could effectively maintain fruit brightness and color saturation,slow down the decrease of firmness,coherency,resilience and chewiness,delay the decline of total soluble solids content during late shelf life and reduce fruit respiratory intensity and ethylene production rate.E-nose analysis showed that the primary volatile component of sweet persimmon was terpene;nitric oxide content in volatile component increased with the rise of storage time.Ellipse distance between TCK in shelf life of 3 d after storage of 30 d and TS in shelf life of 12 d after storage of 30 d were very close;and ellipse distance between TCK in shelf life of 6 d,9 d after storage of 60 d and TS in shelf life of 9 d after storage of 60 d were overlap.This indicated that microenvironment gas regulation with 1-MCP is better in maintaining the volatile component of sweet persimmon during shelf life after accurate phase temperature storage.The analysis was similar with the change of quality and physiology indexes.Therefore,store with microenvironment gas regulation combined with 1-MCP was the best freshkeeping method for sweet persimmon.
