WIPO Patent Application WO/2003/006412

Kind Code:

A1

Abstract:

A method of efficiently producing reduced coenzyme Q₁₀having excellent qualities which is useful in foods, foods with nutrient function claims, foods for specific health uses, nutritional supplements, tonics, animal drugs, drinks, feeds, cosmetics, drugs, remedies, preventives and so on. This method is suitable for industrial production thereof. Namely, a method of producing reduced coenzyme Q₁₀by reducing oxidized coenzyme Q₁₀in an aqueous medium with the use of a hydrosulfite wherein the reduction is carried out in the coexistence of a salt and&sol or under deoxidized conditions at pH 7 or below. Thus, the formation of the oxidized coenzyme Q₁₀ as a by−product due to oxidization can be minimized, thereby giving reduced coenzyme Q₁₀ having excellent qualities at a high yield.
