| 摘 要： | 以普鲁兰多糖、明胶和壳聚糖作为复合涂膜保鲜材料。正交试验时,用9组不同配比复合膜液分别对草莓进行涂敷包装,测定常温下草莓的失重指数和腐烂指数。结果显示：当可食膜液中普鲁兰多糖、明胶和壳聚糖的质量之比为2.5：1.5：1.25时,涂膜对草莓的保鲜效果最好。同时,用该最佳配比下的混合液配置了5种不同质量浓度的膜液,分别对草莓进行涂敷包装,并测定草莓的失重率、烂果率和储存期。结果表明：最佳配比下混合膜液质量浓度为5.25%时,复合涂膜对草莓的保鲜效果最好。

| Abstract: | Pullulan, gelatin and chitosan were used as composite coating films. Strawberries were coated with the composite coating in nine ratios by orthogonal experiment and the weightlessness index and rot index of strawberries were measured under normal temperature. The
experiment showed that when the ratio of the pullulan/gelatin/chitosan composite edible coating film was 2.5:1.5:1.25, its effect of preservation on strawberries was the best. Meanwhile, coating films of five different concentrations in the best proportion were also applied to pack
stawberries, and the weightlessness rate, rot rate and storage period of strawberries were measured. The result showed that the preserving effect of coating with 5.25% complex coating regent was the best. |
