摘要：
This invention relates to a practical and effective process for converting esterified xanthophylls, including zeaxanthin, to non-esterified xanthophylls through saponification. In addition, the invention provides a process for obtaining esterified zeaxanthin in high yields and purities, isolating the xanthophylls from interfering substances such as waxes, oils, and fats. A product of this process is a zeaxanthin rich substrate that is suitable for use in foods, nutritional supplements, cosmetics, pharmaceuticals and related products.
