【Abstract】 Edible gelatin membrane is a safe and natural material, mainly made of the skin of pig, cow and fish. It features its high nutritional value, biodegradability, biocompatibility, antibiotic property and antioxidant property. Additionally, it is also an excellent natural food additive, beneficial in solving the problem of food safety, used as food packaging material to prevent microbial contamination, migration of heavy metal, energy transfer and to extend the shelf life of products. In this paper, the source of raw materials, the preparation of raw materials, the combination of raw materials and the application of raw materials are discussed. There are differences between the different sources of gelatin and their structures. Gelatin made of fish skin has been widely paid attention. Various processing technological methods and reagents can significantly effect on the edible gelatin membrane, such as: solution concentration, pH value, plasticizer, cross-linking agent, metal ion, etc. Compound gelatin film can effectively improve the mechanical properties and biological properties of gelatin film, decreasing the cost and expanding the field of its application. In a word, the development and application of edible gelatin membrane is powerfully explored and is expected to become a excellent biological material.更多还原
