  • Publication number: 20040126338
    Abstract: The invention consists of a process for producing new carotenoid compounds from lutein, which for the purposes of this description the new carotenoids are cis isomers of lutein, zeaxanthin, and lutein esters. The cis-isomer products are carotenoid compounds having UV absorption properties and are formed by preparing a solution of lutein and a liquid, refluxing the solution, cooling the solution to room temperature, and centrifuging the solution to remove trans-lutein crystals. The present invention particularly provides for a product, produced under mild conditions, of cis-isomers, which are preferred due to their increased UV absorption and lighter pigmentation, and thus creating an improved topically applied personal care product further having the same antioxidant characteristics as trans-isomers used before. The cis-isomer products may be used in topically applied personal care products or various food and beverage products and dietary supplements.
