淀粉基膜的制备及应用研究进展

Research progress on preparation and application of starch-based films

淀粉是除纤维素外的第二大可再生原料,淀粉基膜绿色环保、安全无毒、可生物降解,缓解了合成材料的不可降解对生存环境的污染和原料日益枯竭的压力,实现资源的可持续发展,是当今最具有发展前景的新型材料之一。文章对淀粉基膜的制备方法进行了综述,介绍了湿法、干法制备淀粉基膜及其物理化学性质,阐述了淀粉基膜在食品保鲜、包装等领域的应用,并对淀粉基膜的应用前景进行展望。

Starch is the second largest renewable raw materials in the world except for the cellulose.Comparing with the synthetic material,the starch-based films shows more unique and excellent properties such as green,non-toxic,biodegradable.It is one of the most promising new materials because it can ease the pollution to environment and the pressure on the dying up raw material of non-degradable synthetic material,and realize the sustainable development of resources.The main methods of preparing starch-based films including the wet and dry ways were reviewed in the paper.The physical and chemical properties of starch-based films were also summarized.It can be widely used in food fresh keeping,packaging and other fields,and the application prospects of starch-based film were also discussed.
