In order to obtain application effect and optimization of formulation of chitosan coating enriched with cinnamon oil, the formulation and process of chitosan-oil coating were investigated by orthogonal test according to the weight loss rate of Lingwu Long Jujube fruit after treatment. The best formulation was determined as follows: chitosan with the concentration of 1.0% , acetic acid 0.5% , glycerol concentration 0.75% , emulsifier 0.3% , stirring rate 900r/min, stirring time 45 min, and cinnamon oil 0.25%. Application result showed that the chitosan-oil coating treatment exhibited the best control effect on weight loss and decay. Samples treated with chitosan-oil coating reduced the loss of vitamin C in jujube fruit and the accumulation of Malonyldialdehyde ( MDA), which also maintained the good sensory acceptability of jujube fruit.%为了确定壳聚糖生物涂膜保鲜剂的优化配方及其保鲜效果,以枣果实失重率为考核指标,用正交试验获得其优化的配方工艺条件为:壳聚糖1.O％、乙酸0.5％、丙三醇0.75％、吐温-800.3％.剪切乳化速率为900r/min,剪切乳化时间为45 min,肉桂油体积分数为0.25％.该工艺制备的保鲜剂对枣果实和泡菜原料青菜均有较好的保鲜效果.
