低共熔溶剂在类胡萝卜素提取上的应用研究进展

Research Progress on Application of Deep Eutectic Solvent in the Extraction of Carotenoids

类胡萝卜素是一种脂溶性化合物,具有抗氧化、保护视力等作用,对人体健康具有诸多益处。低共熔溶剂(Deep eutectic solvent,DES)是一种新型绿色溶剂,相较于传统有机溶剂,具有制备简单、生物相容性高、生物降解性好、溶剂化效率高、热稳定性好、挥发性低等优点,可应用于食物中天然物质的绿色高效提取,目前在类胡萝卜素提取上的研究尚处于起步阶段。本文简述了DES的性质与分类,重点综述了DES在提取类胡萝卜素上的研究进展,介绍了类胡萝卜素与DES的分离方法,指出了DES在类胡萝卜素提取分离上存在的问题,展望了DES用于类胡萝卜素提取分离的应用前景,以期为类胡萝卜素新型绿色提取溶剂的开发和应用提供借鉴。

Carotenoids are a class of fat-soluble compounds widely associated with human health,because of their antioxidant,vision-protective and other effects.Deep eutectic solvents(DESs)are a new generation of green solvents.DESs are convenient to produce and have higher biocompatibility,biodegradability,solvent efficiency,thermal stability,and lower volatility compared to traditional organic solvents.Although DES has exhibited effective extraction on natural substances in food,its application on the extraction of carotenoids have not yet been widely studied.In this paper,the characteristics and classification of DES are described,the application of DES on extraction of carotenoids is reviewed,the existing problems for the separation of carotenoids from DES are proposed,and the application perspective of DES in the extraction and separation of carotenoids is outlined,aiming to provide a reference for the development and application of new green solvents for carotenoid extraction.
