ABSTRACT:
The present invention provides a method for obtaining reduced coenzyme Q10which is useful as an ingredient in foods, functional nutritive foods, specific health foods, nutritional supplements, nutrients, drinks, feeds, cosmetics, medicines, remedies, preventive drugs, etc. suited for a commercial scale production in high quality and efficiently.The high-quality oily reduced coenzyme Q10which has low viscosity and thereby easily handled may be produced by separating an aqueous phase from the reaction mixture obtainable by oily reacting oxidized coenzyme Q10with a reducing agent in water, or by distilling off an coexisting organic solvent at or above the melting temperature of reduced coenzyme Q10in concentrating the organic phase containing reduced coenzyme Q10. Moreover, a solution or slurry of reduced coenzyme Q10may be obtained by adding a desired solvent to the obtained oily product, or a solid of reduced coenzyme Q10may be produced by contacting the oily product with a seed crystal.
