| 摘 要： | 对壳聚糖膜和壳聚糖纳米氧化锌复合膜的抗拉强度、伸长率、透气性、透湿性进行测试,并用含纳米氧化锌5%(质量分数)的壳聚糖复合溶液制成涂膜液对苹果进行保鲜研究。结果表明:含纳米氧化锌质量分数为5%的壳聚糖复合膜的成膜性,优于壳聚糖膜;涂膜苹果在贮藏期间,壳聚糖纳米氧化锌涂膜组的感官评分、腐烂指数、失重率和维生素C含量的变化,均比壳聚糖膜组和对照组的要小;相对于对照组,壳聚糖膜约延长保质期6 d,壳聚糖纳米氧化锌复合膜约延长保质期9 d。

| Abstract: | The properties of chitosan film and nano-ZnO/chitosan complex film were tested,including tensile strength,elongation,water vapor permeability,and oxygen permeability.The effects of 5% nano-ZnO and chitosan complex film on apple preservation were studied.The results showed that the film formation performance of the complex film is better than that of chitosan film;the reduce of sensory indicator,rotten index,weight loss rate,and vitamin C content of coated apples were less than the uncoated apples and apples... |
