复合海藻酸钠益生菌微胶囊研究进展

Research Progress on Probiotic Microcapsules by Compound Sodium Alginate

海藻酸钠微胶囊制备的研究一直是微胶囊技术的重要组成部分。由海藻酸钠制成的益生菌胶囊有孔隙和裂缝,通过利用不同壁材与海藻酸钠组合形成复合海藻酸钠微胶囊,可对益生菌起到更有效的保护作用。本文概述了三类材料对海藻酸钠微胶囊复合的研究进展,包括添加益生元刺激益生菌增长,共混纳米材料来提升机械性能,利用涂层成膜材料减少外部物质进入或内部芯材渗透。总结不同包埋结构的优缺点,并对益生菌微胶囊包埋的发展趋势进行了展望,以期为复合海藻酸钠益生菌微胶囊的科学研究提供参考。

The preparation of sodium alginate microcapsules is crucial aspect of microcapsule technology.However,probiotic capsules made solely from sodium alginate tend to have pores and cracks,by using different wall materials combined with sodium alginate to form composite sodium alginate microcapsules,it can play a more effective protective effect on probiotics.This paper provides a summary of the research progress made in compounding sodium alginate microcapsules using three different materials,including addition of prebiotics to enhance the growth of probiotics,the blending of nanomaterials to enhance mechanical properties,and the utilization of coating film-forming materials to minimize the ingress of external substances or the permeation of internal core materials.The paper presents a comprehensive overview of the pros and cons of different embedding structures,and provides a projection of the future development of probiotic microcapsule embedding.The ultimate goal is to provide valuable insights for scientific inquiry and experimentation in the field of compound sodium alginate of probiotic microcapsules.
