Carotenoid preparations in the form of coldwater-dispersible powders are produced by

Production of carotenoid preparations in the form of

Finely dispersed carotenoid or retinoid suspensions are prepared by dissolving the carotenoid or retinoid in a volatile, water-miscible organic solvent at 50.degree. C.-250.degree. C., where appropriate under elevated pressure, within less than 10 sec and immediately thereafter mixing the solution with an aqueous medium at from 0 to 90.degree. C., wherein the mixing with the aqueous medium takes place in the absence of a protective colloid and in the presence of at least one physiologically tolerated emulsifier.

Finely dispersed carotenoid and retinoid suspension and their preparation

Liquid, oil-miscible carotenoid preparations which, as double dispersion systems, comprise an aqueous-disperse phase which has a particle diameter of less than 100 .mu.m and in which particles, stabilized by protective colloid, of one or more carotenoids are present in disperse form, in an oil as a dispersion medium.
