The development of edible films and coatings from food-grade biopolymers has advanced significantly during the past decade. The current state-of-the-art lies in the formulation of composite edible films and coatings from such biomolecules. Composite films and coatings refer to systems where multiple biopolymers have been combined to achieve beneficial properties. Carbohydrate, protein, and lipids have been preferred for developing such systems. Binary films and coatings have been prepared from multiple combinations including protein-protein, carbohydrate-carbohydrate and protein-carbohydrate. Similarly, ternary films and coatings have been prepared from protein-protein-carbohydrate combinations. In addition, several active ingredients including antimicrobial compounds have been loaded to these systems for the preparation of functional films and coatings. Therefore, the goal of this manuscript is to review the multitude of composite systems that are currently available for food packaging purposes. In addition, we discuss the application of composite coatings to fruits and vegetables, dairy, meat and seafood as model food systems.
在过去十年中，利用食品级生物聚合物开发可食用薄膜和涂层取得了显著进展。目前的技术水平在于由此类生物分子配制复合可食用薄膜和涂层。复合薄膜和涂层是指将多种生物聚合物组合以实现有益性能的体系。碳水化合物、蛋白质和脂质是开发此类体系的首选材料。二元薄膜和涂层已由多种组合制备而成，包括蛋白质 - 蛋白质、碳水化合物 - 碳水化合物和蛋白质 - 碳水化合物组合。同样，三元薄膜和涂层已由蛋白质 - 蛋白质 - 碳水化合物组合制备而成。此外，包括抗菌化合物在内的几种活性成分已被添加到这些体系中，用于制备功能性薄膜和涂层。因此，本手稿的目的是综述目前可用于食品包装目的的众多复合体系。此外，我们还讨论了复合涂层在水果和蔬菜、乳制品、肉类和海鲜等典型食品体系中的应用。
