Abstract:
Different maturity of fresh Lycium barbarum fruit were used as test materials，they were treated with different concentrations (0(CK),0.75%,1.00%,1.25%) of coating agents of chitosan for 1 minute,and then stored at low temperature (4 ℃) for ten days.The ascorbic acid,soluble solids,titratable acidity,rot rate and weight loss rate of fresh Lycium barbarum fruit were determined every 2 days,the effect of different concentrations of chitosan coating on different maturity of fresh Lycium barbarum fruit during cold storage quality were studied.The results showed that,under low temperature storage conditions,coating treatment of fresh Lycium barbarum fruit could be stored for 8-10 days,and prolonged the shelf life for 1-2 days compared with the control (water treatment).The film coating treatments could effectively reduce the evaporation of fruit water and weight loss rate，delay the decline of contents of soluble solids，titratable acid.Among them，the treatment of 1.25% chitosan had the best preservation effect,appeared rotten fruit after 4 days storage，and postponed 2 days compared with the control.Therefore，chitosan coating treatment was conducive to the preservation of fresh Lycium barbarum fruit.
