Research Progress on Purification Process Optimization and Content Determination of Zeaxanthin

At present, the purification process of zeaxanthin mainly includes organic solvent extraction, ultrasonic-assisted extraction and enzymeextraction, and the content determination technology mainly includes ultraviolet-spectrophotometry and high performance liquid chromatography. In this paper, the purification process and content determination technology of zeaxanthin in recent years are reviewed in order to provide ideas and theoretical basis for further research and application of zeaxanthin.
