ABSTRACT OF THE DISCLOSURE: Pulverulent water-dispersable carotenoid formulations in which the carotenoid is dissolved in an edible oil and the oil solution is in the form of small droplets are prepared by a process in which a carotenoid is rapidly dissolved in a volatile, water-miscible, organic solvent at from 50 to 240°C, together with from 1.5 to 20 times the weight, based on the carotenoid, of an edible oil, and an emulsifier, under atmospheric or superatmospheric pressure, the hydrophilic solvent component is transferred to the aqueous phase from the resulting molecular disperse solution by immediate mixing with an aqueous solution of a protective colloid at from 0 to 50°C, the hydrophobic oil phase which contains the carotenoid in solution being formed as the microdisperse phase, and the resulting two-phase mixture is freed from the solvent and the water in a conventional manner. These formulations are in particular useful for coloring food and animal feeds.
