Polysaccharides, such as pectin, starch, alginate, carrageenan, and xanthan gum, have been used as biopolymer materials to create coatings and edible films to reduce traditional plastic packages. Petrochemical polymers, extensively used for food packaging, are non-renewable and non-biodegradable and need landfills. Thus, there is a requirement to find alternative packaging materials that are easily degradable and renewable. Natural edible polymers are the materials made from natural edible constituents that can be consumed by animals or human beings with no health risk. Since they are directly consumed with food, nothing is left for disposal. Polysaccharides, Protein and Lipid-Based Natural edible polymers are used to make coatings and edible films surrounding the surface of the food. These natural edible polymers are generally categorized into polysaccharides, lipids and proteins. This review article summarizes the importance of various natural polymers used for making coatings and edible films.

诸如果胶，淀粉，藻酸盐，角叉菜胶和黄原胶等多糖已被用作生物聚合物材料，以形成涂层和可食用的薄膜，以减少传统的塑料包装。广泛用于食品包装的石油化学聚合物不可再生且不可生物降解，需要填埋。因此，需要寻找易于降解和可再生的替代包装材料。天然可食用聚合物是由天然可食用成分制成的材料，可以被动物或人类食用而没有健康风险。由于它们直接与食物一起食用，因此一无所有。多糖，蛋白质和基于脂质的天然可食用聚合物用于在食品表面周围形成涂层和可食用薄膜。这些天然的可食用聚合物通常分为多糖，脂质和蛋白质。这篇综述文章总结了用于制造涂料和可食用薄膜的各种天然聚合物的重要性。
