Abstract:
A method of efficiently producing reduced coenzyme Q 10 having 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, reduced coenzyme Q 10 can be handled in a state of being protected from oxidation due to molecular oxygen by bringing the coenzyme Q 10 into contact with a solvent containing a strong acid. By crystallizing in the presence of a strong acid, moreover, coenzyme Q 10 can be converted into crystals while minimizing the formation of the oxidized coenzyme Q 10 as a by−product, thereby giving reduced coenzyme Q 10 having excellent qualities.
Abstract:
A method of conveniently and efficiently producing reduced coenzyme Q 10 having excellent qualities which is useful in foods, foods with nutrient function claims, foods for specific health uses, nutritional supplements, tonics, drinks, feeds, animal drugs, cosmetics, drugs, remedies, preventives and so on. This method is suitable for industrial production thereof. In a method of synthesizing reduced coenzyme Q 10 by reducing oxidized coenzyme Q 10 followed by crystallization, use is made of at least one solvent selected from among hydrocarbons, fatty acid esters, ethers and nitriles. Thus, the reduced coenzyme Q 10 can be protected from oxidization and, in its turn, the formation of the oxidized coenzyme Q 10 as a by−product can be minimized, thereby giving reduced coenzyme Q 10 having excellent qualities.

This method is suitable for industrial production thereof. Namely, a method of producing reduced coenzyme Q 10 by reducing oxidized coenzyme Q 10 in an aqueous medium with the use of a hydrosulfite wherein the reduction is carried out in the coexistence of a salt and/or under deoxidized conditions at pH 7 or below. Thus, the formation of the oxidized coenzyme Q 10 as a by−product due to oxidization can be minimized, thereby giving reduced coenzyme Q 10 having excellent qualities at a high yield.
