Abstract
SummaryPlastics materials used for food packaging are recalcitrant, leading to a growing global environmental problem, which arouses the attention of environmental protection departments in many countries. Therefore, to meet the increasing demand for sustainable and environment‐friendly consumer products, it is necessary for the food industry to develop natural antibacterial materials for food preservation. This review summarizes the common biodegradable natural antimicrobial agents and their applications in food preservation; as well as an overview of five commonly used biodegradable protein‐based polymers, such as zein, soy protein isolate, gelatin and whey protein, with special emphasis on the advantages of protein‐based biopolymers and their applications in food packaging industry.
