Abstract
The present invention is concerned with a process to convert xanthophyll esters derived fromsources to their free (non-esterified) forms. The present invention is concerned with a process for obtainingderived 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.
