摘　　要：以羟乙基纤维素和壳聚糖为原料制备新型共混涂膜液,以其对蓝莓进行涂膜保鲜处理,并与以壳聚糖涂膜液处理及未作处理的蓝莓进行对比,研究共混涂膜液对蓝莓贮藏期间品质的影响。结果表明:共混涂膜液能够有效地降低蓝莓的失重率和腐烂率,在贮藏后期,能够减缓果实硬度的下降速度;采用共混涂膜液处理后,果实的可溶性固形物含量、Vc含量以及花青素含量均呈现出最小的变化。Novel hydroxyethyl cellulose/chitosan（HEC/CS） blend coating was prepared by using HEC and CS as raw materials, and the blend coating was used for the preservation of blueberries. Effects of the blend coating on the quality safety of blueberries were investigated during storage time at room temperature by using pure CS coating treated bluebe- rries and untreated blueberries as controls. Results showed that HEC/CS blending coating could reduce the weight loss and rotting rate of blueberries. Furthermore, blueberries treated with the blending coating presented the minimum changes in total soluble solids, Vc and anthocyanin contents.
