Abstract: Chilled meat is favored by consumers because of its good taste, high nutritional value and safety factor. However, the short shelf life restricts the further development of the cold meat industry, and the preservation of cold meat to extend its shelf life is the key core problem that needs to be solved. As a new type of preservation technology, edible coating could solve the problem of packaging and preservation of cold meat to a certain extent and extend its shelf life. This paper reviewed the principle, process and materials of edible film preservation technology, cited the progress of its application in meat preservation, analyzed the current problems, and presented the outlook on the future research content and development direction, in order to provide reference for the further development and application of this technology in cold meat.
