    Abstract: Process for the production of stable dry powders which are insoluble in hot water and which contain fat-soluble vitamins and/or carotenoids, which comprises the following process steps: a) preparation of an aqueous dispersion containing essentially these fat-soluble active substances, film-forming colloids and reducing sugars, b)conversion of this dispersion into dry powders of vitamin and/or carotenoid products and c) thermal hardening of the powder at temperatures of 60 to 180 DEG C, and which is characterised in that gelatin in combination with one or more organic amino compounds which are free or bound as salts and which contain a basic primary amino group and additionally either another amino group, a hydroxyl group, an alkoxy group or a carboxyl group, and/or in combination with sufficient basic alkali metal or alkaline earth metal compound for the dispersion to have a pH of 7.5 to 10, is used as film-forming colloid, and the dry powders obtainable by this process are described.
