Abstract: Preparation of pulverulent water-dispersible carotenoid preparations in which the carotenoid is present dissolved in an edible oil and the oil solution is present in the form of small droplets, by rapidly dissolving a carotenoid in a volatile, water-miscible, organic solvent at between 50 and 240 DEG C together with from 1.5 to 20 times the weight, based on the carotenoid, of an edible oil and also an emulsifier, under atmospheric or superatmospheric pressure, immediately mixing the resulting molecularly dispersed solution with an aqueous solution of a protective colloid at between 0 DEG C and 50 DEG C to transfer the hydrophilic solvent component into the aqueous phase, forming the hydrophobic oil phase, which contains the carotenoid in solution, as a microdisperse phase, and stripping the resulting two-phase mixture of solvent and water in a conventional manner.

Abstract: Finely divided, pulverulent carotinoid or retinoid compositions, in which the carotinoid or retinoid essentially has a particle size of less than 0.5 micron, are prepared by a process wherein a carotinoid or retinoid is dissolved in a volatile, water-miscible, organic solvent at from 50.degree.C to 200 C, if necessary under superatmospheric pressure, within the space of less than 10 seconds, the carotinoid is immediately precipitated, in a colloidally disperse form, from the molecularly disperse solution by rapidly mixing the latter with an aqueous solution of a swellable colloid at from 0.degree.C to 50.degree.C, and the resulting dispersion is freed from the solvent and the dispersing medium in a conventional manner.

Abstract: O.Z. 0050/034012 Polyelectrolytic titration of serum lipoproteins, the negative surface charge of the latter being determined quantitatively by adding an excess amount of a polycation in aqueous solution to the particular serum lipoprotein and back-titrating the positive charge,of the polycation,which has not been neutralized by the negative surface charge,against a chromotropic polyanion, in the presence of a metachromatic dye as the indicator. The method is used for the diagnosis of lipometabolic disorders.
