Title (EN) METHODS OF SAPONIFYING XANTHOPHYLL ESTERS AND ISOLATING XANTHOPHYLLS
(FR) PROCÉDÉS DE SAPONIFICATION D'ESTERS DE XANTHOPHYLLES ET D'ISOLEMENT DE XANTHOPHYLLES
Abstract: front page image
(EN)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.
(FR)Cette invention porte sur un procédé pratique et efficace pour convertir des xanthophylles estérifiées, comprenant la zéaxanthine, en xanthophylles non estérifiées par saponification. De plus, l'invention porte sur un procédé d'obtention d'une zéaxanthine estérifiée dans des rendements élevés et des puretés élevées, d'isolement des xanthophylles de substances gênantes telles que des cires, des huiles et des graisses. Un produit de ce procédé est un substrat riche en zéaxanthine qui est approprié en vue d'une utilisation dans des aliments, des suppléments nutritionnels, des produits cosmétiques, des produits pharmaceutiques et les produits apparentés.
