摘要:

本实验以紫茄为原料,采用壳聚糖复合涂膜方法对其进行保鲜实验。并采用失重率、还原糖为指标,以正交试验优化保鲜膜配方。结果表明,保鲜膜最佳配方为:壳聚糖浓度1.5%、乙酸浓度10%、吐温20 浓度0.03%、1,2- 丙二醇的浓度3%。

关键词: 壳聚糖, 紫茄, 正交实验, 保鲜

Abstract:

Chitosan coating technology was used to preserve purple eggplant in this study. With weight loss rate and reducing sugar content as analysis indexes, orthogonal tests were conducted to optimize the formula of chitosan coating. The results showed that the optimal formula is as follows: chitosan concentration 1.5%, acetic acid concentration 10%, Tween-20 concentration 0.03 % and 1, 2 - propylene glycol concentration 3%.

Key words: chitosan, purple eggplant, orthogonal test, preservation
