  • Preparation of finely divided, pulverulent carotenoid preparations
    Patent number: 4726955
    Abstract: Finely divided, pulverulent carotenoid preparations in which the carotenoid essentially has a particle size of less than 0.5 micron are prepared by a process in which a carotenoid is dissolved in a volatile, water-miscible, organic solvent at from 50.degree. to 240.degree. C., under atmospheric or superatmospheric pressure, in less than 10 seconds, the carotenoid is precipitated in colloidal disperse form from the resulting molecular disperse solution by rapid mixing with milk at from 0.degree. to 50.degree. C., and the resulting dispersion is freed from the solvent and the dispersing medium in a conventional manner.
