鼠李糖脂的分离鉴定及其在食品中的应用研究进展

Advances in the isolation and identification of rhamnolipids and their application in foodstuffs

鼠李糖脂(rhamnolipids,RLs)是一种天然的具有多种生物活性的脂类物质,由于其具有促进发酵起泡、抑制细菌生物膜形成和调节免疫等功能,可广泛应用于食品、医药和农业等领域。目前工业上已经采用微生物发酵法对RLs进行生产制备。RLs作为最有前途的商业化生物表面活性剂,高效、准确的鉴定和表征RLs对其生产、应用至关重要。本文介绍了RLs的生产方法 ,重点概述RLs的分离纯化工艺和鉴定技术,并总结了RLs在食品领域的应用现状,为今后RLs活性开发及应用提供参考,推动其在食品领域的工业化进程。

Rhamnolipids(RLs)are natural lipids with a variety of biological activities,which can be widely used in the fields of food,medicine and agriculture due to their functions of promoting fermentation foaming,inhibiting bacterial biofilm formation and regulating immunity.At present,RLs has been produced and prepared by microbial fermentation in industry.RLs is the most promising commercial biosurfactant,and efficient and accurate identification and characterization of RLs is very important for its production and application.This paper described the production methods of RLs,focused on outlining the separation and purification processes and identification techniques of RLs,and summarized the current status of the application of RLs in the food field,to provide a reference for the future development of RLs activity and application,and to promote their industrialization in the food field.
