虾青素的运载体系研究进展

Recent research advances in the delivery systems for astaxanthin

虾青素具有抗氧化、预防癌症和提高机体免疫力等生理功能,然而化学稳定性和水溶性较差,限制了其在食品和医药等方面的应用。通过乳液、微胶囊、纳米颗粒、脂质体和纳米结构脂质等不同的体系运载虾青素可拓宽其应用范围。介绍了虾青素的生理功能,综述了近几年国内外运载虾青素的体系研究现状,对每种运载体系的优缺点进行了归纳。此外,通过分析比对多种运载体系的构建方法、技术手段及运载效率,整理出虾青素运载体系优化思路,旨在为虾青素运载体系在食品行业中的应用提供理论参考。

Astaxanthin has many excellent physiological functions such as anti-oxidation,immunity enhancement,cancer prevention and anti-inflammation.However,astaxanthin has poor chemical stability and water solubility,which affect the application of astaxanthin in food and medicine.Therefore,astaxanthin can be loaded in different delivery systems to broaden its application range,such as emulsion,microcapsules,nanoparticles,and liposomes,which can effectively improve the bioavailability of astaxanthin.This paper briefly outlines the physiological functions of astaxanthin,and discusses the optimization methods of astaxanthin delivery systems by summarizing the relevant domestic and international studies in recent years,in order to provide theoretical references for the development of astaxanthin delivery systems in food industry.
