A process for preparing a stable, aqueous dispersion or a stable water-dispersible dry powder of xanthophylls selected from the group consisting of astaxanthin, lutein and zeaxanthin, bya) dissolving one or more of the abovementioned xanthophylls in a water-miscible organic solvent or a mixture of w
A process for preparing a stable, aqueous dispersion or a stable water-dispersible dry powder of xanthophylls selected from the group consisting of astaxanthin, lutein and zeaxanthin, bya) dissolving one or more of the abovementioned xanthophylls in a water-miscible organic solvent or a mixture of water and a water-miscible organic solvent at temperatures above 30° C.,b) mixing this solution with an aqueous solution of a protective colloid, the solvent component being transferred into the aqueous phase, and the hydrophobic phase of the xanthophyll resulting as nanodisperse phasec) and, where appropriate, converting the dispersion which has formed into a water-dispersible dry powder by removing the solvent and the water and drying, where appropriate in the presence of a coating material,wherein casein or a caseinate is used as protective colloid in step b).

1. A process for preparing a stable, aqueous dispersion or a stable water-dispersible dry powder of xanthophylls selected from the group consisting of astaxanthin, lutein and zeaxanthin, bya) dissolving one or more of the xanthophylls selected from the group consisting of astaxanthin, lutein and zeaxanthin in a water-miscible organic solvent or a mixture of water and a water-miscible organic solvent at temperatures above 30° C., b) mixing this solution with an aqueous solution of a protective colloid, the solvent component being transferred in to the aqueous phase, and the hydrophobic phase of the xanthophyll resulting as nanodisperse phase c) and, where appropriate, converting the dispersion which has formed into a water-dispersible dry powder by removing the solvent and the water and drying, where appropriate in the presence of a coating material, wherein casein or a caseinate is used as protective colloid in step b). 2. A process as claimed in claim 1, wherein an edible oil is used in addition to the xanthophyll in step a).3. A process as claimed in claim 1, wherein no additional emulsifier is used.4. A process as claimed in claim 1, wherein the formation of H aggregates of the xanthophylls is avoided.5. A process as claimed in claim 1, wherein astaxanthin is used as xanthophyll.6. A stable aqueous dispersion of xanthophylls selected from the group consisting of astaxanthin, lutein and zeaxanthin, obtainable by a process as defined in claim 1.7. A stable aqueous dispersion of xanthophylls as claimed in claim 6, wherein the xanthophyll present has an amorphous content between 70 and 100%.8. A stable aqueous dispersion of xanthophylls as claimed in claim 6, wherein the xanthophyll present has an all-trans isomer content of at least 50%.9. A stable aqueous dispersion of xanthophylls as claimed in claim 6, which shows the viscosity behavior of newtonian fluids.10. A stable aqueous dispersion of xanthophylls as claimed in claim 6, which is a dispersion of astaxanthin.11. A stable water-dispersible dry powder of xanthophylls selected from the group consisting of astaxanthin, lutein and zeaxanthin, obtainable by a process as defined in claim 1.12. A stable water-dispersible dry powder of xanthophylls as claimed in claim 11, which is a dry powder of astaxanthin.13. Human foods, pharmaceuticals and/or animal feeds comprising the stable aqueous dispersions and/or stable water-dispersible dry powders of xanthphylls defined in claim 6.
