改性乳酸菌微胶囊壁材的研究进展

摘要

乳酸菌微胶囊所用壁材主要为生物相容性良好的天然高分子材料.然而天然材料的结构种类有限,不能持续地提高微胶囊对乳酸菌活菌数量的保护作用.改性壁材可以根据用途对原有材料进行结构改造,在保持良好生物相容性的前提下,赋予壁材更好的保护功能.该文综述了国内外改性微胶囊壁材在乳酸菌微胶囊化方面的研究进展.%Biocompatible natural polymer materials are mainly uesd as the matrix of lactic acid bacteria micro-capsule. However, the protective effect on the viability of lactic acid bateria could not be consistently improved becasue of the limited structure of natural materials. Modified polymers with good biocompatibility and better protective effect could be obtained by modifying the original materials according to the application purpose. This paper reviewed the research progress of some modified polymer materials for lactic acid bacteria microencapsu-lation.
