Application Research Progress of Edible Protein Film in Food Packaging

With the increasing awareness of environmental protection and the improvement of food preservation quality and packing requirements,the research of green and natural food packaging film has become a focus,among which non-toxic and environmentally friendly edible protein packaging film has become a research hot spot in recent years. In this paper,the advantages and disadvantages,preparation methods and main application fields of three kinds of protein films,including the animal protein film,the plant protein film,and the composite protein film,are briefly introduced. And the characteristics,functions,and progress of the research about edible protein films in food packaging at home and abroad are summarized,which provide certain reference for the subsequent application research and industrialization development of edible protein films. In the future,as the preparation process of edible protein films are further optimized,edible protein films are expected to develop better in the direction of multi-function and intelligence.
