虾青素的来源与先进递送体系的研究进展OA

Astaxanthin,as a natural carotenoid with outstanding antioxidant activity,has attracted much attention in the fields of food,medi-cine and cosmetics.However,its poor stability and low bioavailability have severely restricted its application.Astaxanthin is widely distributed in Marine microalgae,phytoplankton,and most crustaceans and aquatic animals.Its natural and synthetic sources each have their own charac-teristics.This article systematically expounds the research progress of advanced delivery systems such as emulsions,microcapsules and lipo-somes in enhancing the bioavailability,stability and targeted delivery of astaxanthin.By encapsulating astaxanthin in the delivery system,not only can its stability and bioaccessibility be significantly enhanced,but also the release rate can be controllable and adjusted,thereby more ef-fectively exerting its biological activity.The development of an advanced astaxanthin delivery system is a key strategy to systematically break through the bottleneck of its bioavailability,which can provide key technical support for the efficient industrialization of astaxanthin in related fields.
