摘要:
以壳聚糖（chitosan，CH）、纳米ZnO、黄芪提取物（Astragalus membranaceus (Fisch.) Bunge.Extract，AME）为试材，进行复合涂膜制备，采用正交实验法，以腐烂率和失重率为评价指标，研究了不同质量浓度配比复合涂膜对草莓在贮藏期的保鲜效果，以期为草莓采后贮藏保鲜提供参考依据。结果表明：CH-纳米ZnO-AME复合〖JP2〗涂膜最佳涂膜配方为1.75%CH+0.7%纳米ZnO+0.5%甘油+0.2% AME。与CK组相比，CH-纳米ZnO-AME复合涂膜显著降低了贮藏期间草莓的腐烂率和失重率，延缓了草莓硬度和可溶性固形物含量的降低。此外，CH-纳米ZnO-AME复合涂膜在降低草莓腐烂率和失重率以及维持硬度等指标方面均优于其它处理组。综上所述，壳聚糖-纳米ZnO-黄芪提取物复合涂膜处理对提高新鲜草莓品质具有积极作用。
Abstract:
Chitosan (CH)，nano ZnO，and Astragalus membranaceus (Fisch.) Bunge.Extract (AME) were used as the experimental material for the preparation of composite coatings.Orthogonal experimental methods were used to evaluate the preservation effect of composite coatings with different mass concentration ratios on strawberries during storage，using decay rate and weight loss rate as evaluation indicators,in order to provide reference for the storage and preservation of strawberries after harvest.The results showed that the optimal composite film was 1.75% CH+0.7% nano ZnO+0.5% glycerol+0.2% AME.Compared with the CK group，the CH-nano ZnO-AME composite coating significantly reduced the decay rate and weight loss rate of strawberries during storage，delaying the decrease in firmness and soluble solid content.In addition，the CH-nano ZnO-AME composite coating was superior to other treatment groups in reducing strawberry decay rate，weight loss rate，and maintaining firmness.In summary，the composite coating treatment of CH-nano ZnO-AME had a positive effect on improving the quality of fresh strawberries.
