    摘要: Preparation of a stable aqueous dispersion, or a stable water-dispersible dry powder, of xanthophylls, which comprises a) preparing a molecularly dispersed solution of at least one xanthophyll, with or without an emulsifier and/or an edible oil, in a water-miscible organic solvent, or a mixture of water and a water-miscible organic solvent, at above 30° C., b) mixing this solution with an aqueous solution of a mixture of protective colloids, b1) in which the mixture comprises at least one low-molecular-weight protective colloid component and at least one high-molecular-weight protective colloid component, whose mean molecular weights differ by at least 10,000, b2) the solvent component being transferred to the aqueous phase and the hydrophobic phase of the xanthophyll being formed as a nanodispersed phase c) and if appropriate, to prepare a water-dispersible dry powder, freeing the resulting dispersion from the solvent and the water and drying it in the presence or absence of a coating material.

    摘要: 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, by a) 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 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).
