Abstract: PROBLEM TO BE SOLVED: To provide a method for producing carotenoid-containing dry powder by using protective colloids which do not display disadvantages of the prior art. SOLUTION: This method for producing dry powder containing one or more carotenoids is characterized by comprising (a) dispersing one or more carotenoids in an aqueous molecular or colloidal solution of a mixture of lactose and a protective colloid and (b) converting the resultant dispersion into a dry powder by removing the water and, where appropriate, additionally used solvents from the dispersion and carrying out drying, as necessary in the presence of a coating material, wherein at least one soybean protein is used as protective colloid in the process step (a).

Abstract: In a process for producing a stable, aqueous dispersion or a stable, water- dispersible dry xanthophyl] powder: (a) a molecular disperse solution of at least one xanthophyll if required together with an emulsifier and/or an edible oil is produced in a water-miscible organic solvent or in a mixture of water and a water-miscible organic solvent, at temperatures above 30 .degree.C; (b) this solution is mixed with an aqueous solution of a mixture of protective colloids; (b1) the mixture containing at least one low molecular protective colloid component and at least one high molecular protective colloid component whose molecular weights differ by at least 10,000; (b2) the solvent component being convened into the aqueous phase and the hydrophobic phase of the xanthophyll being produced as a nanodisperse phase; and (c) if required, the thus obtained dispersion is freed from solvent and water to produce a water-dispersible dry powder and dried, if required in the presence of a coating material.
