多糖类可食性膜的研究进展

摘要

Edible films represent an important research direction in food packaging. In particular, those prepared with polysaccharides are highly favored because of their good uniformity and transparency. Today, research efforts are focused on endowing edible films with a wider range of biological activities such as antioxidant and antimicrobial in addition to improving their applicability, thus presenting promising application prospects. The main components, properties, film-forming mechanisms and biological activities of edible films prepared with polysaccharides are reviewed in this paper. Furthermore, future application prospects are also discussed.%可食性膜是目前食品包装领域研究的重要方向,其中,多糖类可食性膜因具有均匀、透明等特点而备受青睐.目前,多糖类可食性膜的研究主要集中在改善其应用性能的同时,赋予其抗氧化性、抑菌性等更多的生物活性,因此展现出良好的应用前景.本文在简要介绍多糖类可食性膜的主要组成、性能的基础上,对其成膜机理、生物活性及应用发展进行了综述.
