The development of active packaging films and edible coatings based on biopolymers and natural bioactive substances has received increasing attention in recent years. Propolis, also called bee glue, is a natural resin substance collected by worker-bees from the mucilage, gum, and resin of several plants. In food industry, propolis is commonly extracted in solvents to afford polyphenol-rich extract with potent antimicrobial and antioxidant activities. The prepared propolis extract can be mixed with biopolymers, plasticizers, emulsifiers, and reinforcing agents to develop active packaging films and edible coatings. The functionality of active packaging films and edible coatings is closely related to the type, harvesting method, geographic origin, extraction method and extraction conditions of propolis, the content and composition of polyphenolic compounds in the extract, and the presence of other bioactive substances. Active packaging films and edible coatings based on propolis extract can impact the physical, biochemical, and sensory properties of food (e.g., fruits, vegetables, meat, and fish) during storage. This review focuses on the recent advances of active packaging films and edible coatings based on polyphenol-rich propolis extract. The impact of polyphenol-rich propolis extract on the structural characterization, functionality, and potential food applications of the films and edible coatings is summarized.
近年来，基于生物聚合物和天然生物活性物质的活性包装薄膜和可食用涂层的开发受到了越来越多的关注。蜂胶，也称为蜂蜡，是工蜂从几种植物的黏液、树胶和树脂中采集的天然树脂物质。在食品工业中，蜂胶通常在溶剂中提取，以获得具有强大抗菌和抗氧化活性的富含多酚的提取物。制备的蜂胶提取物可与生物聚合物、增塑剂、乳化剂和增强剂混合，以开发活性包装薄膜和可食用涂层。活性包装薄膜和可食用涂层的功能与蜂胶的类型、收获方法、地理来源、提取方法和提取条件、提取物中多酚化合物的含量和组成以及其他生物活性物质的存在密切相关。基于蜂胶提取物的活性包装薄膜和可食用涂层在储存过程中会影响食品（如水果、蔬菜、肉类和鱼类）的物理、生化和感官特性。本文综述了基于富含多酚的蜂胶提取物的活性包装薄膜和可食用涂层的最新进展。总结了富含多酚的蜂胶提取物对薄膜和可食用涂层的结构表征、功能以及潜在食品应用的影响。
