摘要
明胶基薄膜具有优异的机械性能、阻隔性能、抗氧化和抗菌活性等特性,已广泛应用于食品包装中。该文概述了明胶的特性,总结了明胶基薄膜的制备方法,包括溶液浇铸法、熔融挤出法、涂膜法和静电纺丝法;阐述了不同增塑剂对明胶基薄膜性能的影响,并综述了明胶基复合薄膜的研究进展,涵盖明胶与糖类化合物、酚类化合物、蛋白质和纳米材料等复合体系,探讨了明胶基复合薄膜在果蔬保鲜、肉类保鲜和其他食品包装中的应用。对明胶基复合薄膜在食品包装领域的发展进行了展望,期望为绿色化、高性能化、多功能性明胶基食品包装薄膜的开发利用提供参考。
Gelatin-based composite films have been widely used in food packaging due to their excellent mechanical properties,barrier properties,antioxidant and antimicrobial activities.In this review,the properties and advantages of gelatin were summarized.The preparation methods,including solution casting,melt extrusion,film coating and electrostatic spinning,of gelatin-based composite films were described,and the effect of different plasticizers on gelatin-based film was analyzed.The research process on gelatin-based composite films was then reviewed,including the composite systems of gelatin with carbohydrates,phenolic compounds,proteins and nanomaterials,while the application of gelatin-based films in fruit and vegetable preservation,meat preservation and other food products was discussed.Finally,a brief outlook on the development of gelatin-based composite films in the field of food packaging was given to provide reference for the development and utilization of green,high performance and multi-functional gelatin-based films.
