Zeaxanthin is a kind of natural carotenoid containing oxygen, which exists in a large number of plant tissues such as yellow corn, wolfberry, acid pulp fruit and some non-photosynthetic bacteria. It can effectively prevent the occurrence of cancer, cataracts, cardiovascular and age-related macular decline and other diseases. At present, the purification process of zeaxanthin mainly includes organic solvent extraction method, ultrasonic assisted extraction method and enzyme extraction method, and the content determination technology mainly includes UV-spectrophotometry and high performance liquid chromatography. In this paper, the purification technology and content determination technology of zeaxanthin in recent years are reviewed in order to provide ideas and theoretical basis for further development and application of zeaxanthin.
