中文摘要:

      淀粉基可食膜作为可食膜中的重要组成部分, 具有安全、可降解、成本低和来源广等诸多优点。壳聚糖因其具有生物可降解、抗氧化、抗菌、成膜性好等诸多优点被广泛应用于食品包装膜中。将壳聚糖应用于淀粉基可食膜中, 开发具有良好生物降解性和安全性的壳聚糖淀粉基食品包装材料, 是食品包装行业的研究热点。本文综述了壳聚糖的结构、成膜性及生物活性, 阐明了壳聚糖淀粉基可食膜成膜机理及壳聚糖在不同种类淀粉基质中的成膜性质。讨论了壳聚糖淀粉基复合可食膜, 在肉类、水果蔬菜、以及其他食品中的应用。随着研究深入, 壳聚糖淀粉基可食包装膜在未来具有广阔的发展前景, 本文为壳聚糖在淀粉基可食膜中的应用提供了依据和方向, 为其在新型食品包装中的应用提供了良好理论基础。

英文摘要:

      Starch as an important component of edible films, has many advantages such as safety, degradability, low cost, and wide availability. Chitosan is widely used in food packaging films due to its good biodegradability, antioxidant, antibacterial, and good film-forming properties. The application of chitosan in starch based edible films and the development of packaging materials with good biodegradability and safety is a research hotspot in the food packaging industry. This paper reviewed the structure, film-forming properties, and biological activity of chitosan, and elucidated the film-forming mechanism of chitosan starch based edible films and the film-forming properties of chitosan in different types of starch matrices, discussed the application of chitosan-starch composite edible film in meat, fruits, vegetables, and other foods. With the deepening of research, chitosan starch based edible packaging film has broad development prospects in the future. This paper provides a basis and direction for the application of chitosan in starch based edible film, and provides a good theoretical basis for its application in new food packaging.
