摘　　要：明胶是一种天然生物高分子,来源广泛,价格低廉,具有良好的成膜性、生物相容性、生物降解性等。作为膜材料,单一成分的明胶膜存在着热稳定性差、机械强度低、对水敏感、潮湿环境下易变质等缺陷,通常需要对其进行改性处理。明胶通过与蛋白质、糖类、脂类复合,或添加活性功能成分可以改善明胶基膜的性能,从而使明胶基膜具有广阔的应用前景。本文综述了明胶与生物聚合物、活性功能成分复合制备明胶基复合膜的研究进展及其在食品包装上的应用。Gelatin is a very important natural biopolymer with wide range of sources,low cost,good film-forming,biocompatibility,biodegradability and so on.However,the pure gelatin film is poor in thermal stability and mechanical strength,water-sensitive,perishable defects,thus it need to be modified.Composite films can be created by mixing gelatin with protein,carbohydrate and lipid,or additives,which can improve the performance of gelatin-based films,so that the gelatin-based films have broad applications. The progress of gelatin-based composite films and their application in food packaging were briefly reviewed in this paper.
