摘要:
The present invention provides a method for obtaining reduced coenzyme Q10 which 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 Q10 which 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 Q10 with a reducing agent in water, or by distilling off an coexisting organic solvent at or above the melting temperature of reduced coenzyme Q10 in concentrating the organic phase containing reduced coenzyme Q10. Moreover, a solution or slurry of reduced coenzyme Q10 may be obtained by adding a desired solvent to the obtained oily product, or a solid of reduced coenzyme Q10 may be produced by contacting the oily product with a seed crystal.

摘要:
The present invention provides a stabilization method, a preservation method and the like method of reduced coenzyme Q10, which is useful as functional nutritive foods, specific health foods and the like. Furthermore, the present invention provides a method for efficiently obtaining reduced coenzyme Q10 of high quality and by a method suitable for a commercial production. It is possible to handle and stably preserve reduced coenzyme Q10 under a condition that oxidation by a molecular oxygen is inhibited by contacting reduced coenzyme Q10 with an ascorbic acid and citric acid or a related compound thereof, and thus a stabilized composition is obtained. Moreover, reduced coenzyme Q10 is converted into a crystalline state in such a condition that the formation of oxidized coenzyme Q10 as a byproduct is minimized by crystallizing reduced coenzyme Q10 in the presence of ascorbic acid or a related compound thereof, etc., and thus a reduced coenzyme Q10 crystal of high quality is produced. Furthermore, by successively crystallizing the generated reduced coenzyme Q10, in the presence of ascorbic acid or related compound thereof after reducing oxidized coenzyme Q10 to reduced coenzyme Q10 using ascorbic acid or a related compound thereof, operations are simplified and minimized, and thus reduced coenzyme Q10 of high quality is produced.
