Patent ID: 8568779

Claim:
A method of producing coenzyme Q 10 particles, comprising (a) mixing coenzyme Q 10 and a poor solvent by stirring at a temperature not less than the melting point of coenzyme Q 10 , which results in dispersed coenzyme Q 10 in the form of oil droplets, (b) cooling the resulting dispersion to a solidification temperature of coenzyme Q 10 or below while stirring, thereby maintaining the dispersion to yield coenzyme Q 10 solid particles, and (c) performing solid-liquid separation to obtain dry coenzyme Q 10 particles, wherein the dry coenzyme Q 10 particles are spherical or granular particles having a mean particle size of 50 to 1000 μm, and wherein the poor solvent is an aqueous solution comprising an organic solvent and/or a high-HLB surfactant having an HLB of 6 or above wherein the concentration of the of the high-HLB surfactant in the poor solvent is not more than 1 wt %.
