Edible coatings and films represent an alternative packaging system characterized by being more environment- and customer-friendly than conventional systems of food protection. Research on edible coatings requires multidisciplinary efforts by food engineers, biopolymer specialists and biotechnologists. Entrapment of probiotic cells in edible films or coatings is a favorable approach that may overcome the limitations linked with the use of bioactive compounds in or on food products. The recognition of several health advantages associated with probiotics ingestion is worldwide accepted and well documented. Nevertheless, due to the low stability of probiotics in the food processing steps, in the food matrices and in the gastrointestinal tract, this kind of encapsulation is of high relevance. The development of new and functional edible packaging may lead to new functional foods. This review will focus on edible coatings and films containing probiotic cells (obtaining techniques, materials, characteristics, and applications) and the innovative entrapment techniques use to obtained such packaging.
可食用涂层和薄膜是一种替代性包装系统，其特点是比传统的食品保护系统更环保、更受消费者欢迎。可食用涂层的研究需要食品工程师、生物聚合物专家和生物技术专家的多学科努力。将益生菌细胞包埋在可食用薄膜或涂层中是一种有利的方法，它可以克服与在食品中或食品上使用生物活性化合物相关的局限性。摄入益生菌具有多种健康益处，这一观点已得到全球认可且有充分的文献记载。然而，由于益生菌在食品加工步骤、食品基质和胃肠道中的稳定性较低，这种包封方式具有重要意义。新型功能性可食用包装的开发可能会带来新的功能性食品。本综述将重点关注含有益生菌细胞的可食用涂层和薄膜（制备技术、材料、特性及应用）以及用于制备此类包装的创新性包埋技术。
