Abstract：
Edible films and coatings (EFC) are macromolecular-based structures forming thin layers that are usually studied as tools to improve food stability, sometimes being considered as parts of both the packaging system and the food itself. However, EFC are not mere packaging materials, and sometimes they do not even play roles related to those of packaging. This graphical review summarizes possible roles of EFC, including primary packaging, keeping water activity gradients between food components, controlling mass transfer on food processing, carrying active components, or serving as sources of sensory appeal. EFC may even be designed in a way that two or more of those roles may be played simultaneously.
摘要：
可食用薄膜和涂层（EFC）是基于大分子的结构，形成薄层，通常作为提高食品稳定性的工具进行研究。有时被认为是包装系统和食品本身的一部分。然而,EFC不仅仅是包装材料，有时它们甚至不扮演与包装有关的角色。本图表总结了EFC的可能作用，包括初级包装，保持食物成分之间的水分活度梯度，控制食品加工的传质，携带活性成分，或者作为感官吸引力的来源。EFC甚至可以以可以同时扮演这些角色中的两个或更多个的方式设计。
