Patent
CA 2214480
Carotenoid preparations in the form of coldwater-dispersible powders are produced by 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, heating the resulting hydrosol at from 40°C to 90°C, with or without cooling of the hydrosol to from 0°C to 30°C beforehand, and removing the solvent and the water from the heated hydrosol, and converting it into a water-dispersible dry powder.
