摘　　要：探究制备壳聚糖膜的成分比例以及工艺流程,确保成品膜物理性能达标。2%的乙酸、0.5%甘油以及40℃的成膜条件能制备物理性能较优的壳聚糖膜。茶多酚浓度的大小决定膜的还原性、抑菌性,壳聚糖与柠檬酸对其性质不作影响。本课题设计的成品具有较优的物理性质与抑菌性,同时具有可降解性、无抗原性、易得性等,对制备环保抑菌的保鲜膜具有一定意义。The composition ratio and technological process of preparing chitosan film were explored to ensure the physical properties of finished film meet the standards.Chitosan films with better physical properties were prepared by 2%acetic acid,0.5%glycerin and 40℃.The reducing and bacteriostatic properties of tea polyphenols were determined by the concentration of tea polyphenols,but chitosan and citric acid did not affect the properties.The finished product designed in this subject has better physical properties and bacteriostasis,as well as degradability,no antigenicity,accessibility,etc.,which has a certain significance for the preparation of environmental protection and bacteriostasis plastic wrap.
