    Abstract: 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.

    Abstract: The present invention is concerned with a process to convert xanthophyll esters derived from Capsicum sources to their free (non-esterified) forms. The present invention is concerned with a process for obtaining Capsicum derived xanthophylls that meet the finished product needs for purity, yield, ease of use, industrial compatibility and cost that are required to make product suitable for the nutritional supplement, food and beverage industries. The present invention is concerned with a process which yields from 60 to 80%, of xanthophyll materials and nearly quantitative recovery of all input xanthophylls, which xanthophylls are of high purity. The present invention concerns a method to obtain xanthophyll esters present almost exclusively in the trans form when isolated from the natural plant sources. The present invention concerns a process to re-convert cis product back to the more desired trans form.
