Abstract: 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).

Abstract: Carotenoid preparations in the form of coldwater-dispersible powders are produced by a) preparing a molecular-disperse solution of a carotenoid, with or without an emulsifier and/or an edible oil, in a volatile, water-miscible, organic solvent at elevated temperature and adding therein an aqueous solution of a protective colloid, whereupon the hydrophilic solvent component is transferred into the aqueous phase, and the hydrophobic phase of the carotenoid results as nanodisperse phase, b) heating the resulting hydrosol at from 40.degree.C to 90.degree.C, with or without cooling of the hydrosol to from 0.degree.C to 30.degree.C beforehand, and c) removing the solvent and the water from the heated hydrosol, and converting it into a water-dispersible dry powder.
