The versatile use of carotenoids in feed, food, cosmetic and pharmaceutical industries has emphasized the optimization of extraction methods to obtain the highest recovery. The choice of method for carotenoid extraction from food matrices is crucial, owing to the presence of diverse carotenoids with varied levels of polarity, and the presence of various physical and chemical barriers in the food matrices. This review highlights the theoretical aspects and recent developments of various conventional and nonconventional methods used for the extraction of carotenoids, including ultrasound-assisted extraction (UAE), pressurized liquid extraction (PLE), and supercritical fluid extraction (SFE). Recent applications of non-toxic and environmentally safe solvents (green solvents) and ionic liquids (IL) for carotenoid extraction are also described. Additionally, future research challenges in the context of carotenoids extractions are also identified.
类胡萝卜素在饲料、食品、化妆品和制药行业的广泛应用凸显了优化提取方法以实现最高回收率的重要性。由于食品基质中存在极性各异的多种类胡萝卜素以及各种物理和化学屏障，从食品基质中提取类胡萝卜素的方法选择至关重要。本综述重点介绍了用于类胡萝卜素提取的各种传统和非传统方法的理论方面及最新进展，包括超声辅助提取（UAE）、加压液体提取（PLE）和超临界流体提取（SFE）。还描述了无毒且环境安全的溶剂（绿色溶剂）和离子液体（IL）在类胡萝卜素提取中的最新应用。此外，还确定了类胡萝卜素提取方面未来的研究挑战。
