摘要： The present invention relates to a process for the preparation of an xanthophyll, and in particular to a process for the preparation of an xanthophyll through the oxidation of a carotenoid in the presence of hydrogen peroxide and an iodine-containing compound. In particular, the process of the invention applies to the oxidation of beta-carotene to produce canthaxanthin, and to the oxidation of lutein or zeaxanthin to produce astaxanthin.

摘要： A process for the production of carotenoids crystals from a carotenoid-containing plant oleoresin which process comprises (a) a first step of introducing the oleoresin to an organic solvent, an alcohol and a base under reflux temperature of the organic solvent to form a saponification reaction mixture; (b) maintaining said saponification reaction mixture for a period of time sufficient to complete the saponification reaction, thereby producing a saponified product; (c) allowing the resulting saponifiied product to separate into two phases comprising an organic phase and an aqueous phase; (d) separating said phases and extracting the extracting the aqueous phase; (e) distilling said organic phase to obtain the carotenoid crystals.
