| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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 coated with chitosan film. Compared with the uncoated apples, the storage life of apples coated with chitosan film and nano-ZnO/chitosan complex film extend by 6 days and 9 days respectively. |
