Method of producing reduced coenzyme Q10 using solvent with high oxidation-protective effect

Abstract

The present invention relates to a method of conveniently and efficiently producing reduced coenzyme Q10 having excellent qualities which is useful in foods, functional nutritive foods, specific health foods, nutritional supplements, nutrients, drinks, feeds, animal drugs, cosmetics, medicines, remedies, preventive drugs, etc. This method is suitable for industrial production thereof. In a method of synthesizing reduced coenzyme Q10 by reducing oxidized coenzyme Q10, followed by crystallization, at least one species selected from among hydrocarbons, fatty acid esters, ethers and nitrites is used as a solvent. Thus, the reduced coenzyme Q10 can be protected from oxidation, and as a result, the formation of the oxidized coenzyme Q10 as a by-product can be minimized, thereby giving reduced coenzyme Q10 having excellent qualities.
