Abstract:
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.

Abstract:
The present invention relates to a method for stabilizing reduced coenzyme Q10, which is useful as an ingredient in good foods, functional nutritive foods, specific health foods, nutritional supplements, nutrients, animal drugs, drinks, feeds, cosmetics, medicines, remedies, preventive drugs, etc., and to a composition therefor. The composition comprises reduced coenzyme Q10, a fat and oil (excluding olive oil) and/or a polyol, and doesn't substantially inhibit the stabilization of reduced coenzyme Q10. Additionally, the composition is a reduced coenzyme Q10-containing composition which comprises reduced coenzyme Q10, a polyglycerol fatty acid ester, and a fat and oil and/or a polyol.
Abstract:
The present invention aims to provide a component having not only an ability to reduce oxidized coenzyme Q10 and an ability to stabilize reduced coenzyme Q10, but also nutrient, flavor, broad utility and the like, and a utilization method thereof. The present invention relates to a safe and convenient method of producing reduced coenzyme Q10, including reducing oxidized coenzyme Q10 by using, as a component derived from a naturally-occurring substance, which is safe for the body, any one or more components selected from the group consisting of an acerola extract, a tea extract, a rosemary extract, a pine bark extract and a Vaccinium vitis-idaea extract. In addition, the present invention also relates to a method of stabilizing reduced coenzyme Q10 in the co-presence of a component derived from a naturally-occurring substance, and a stabilized composition. Since the above-mentioned components derived from a naturally-occurring substance can also be expected to function as nutrients, the composition of the present invention is particularly useful as a pharmaceutical product, a supplement, a food with nutrient function claims, a food for specified health use, a nutritional supplement, a nutritional product, an animal drug, a cosmetic, a therapeutic drug and the like, which are required to show various effects.
Abstract:
The present invention relates to a process for producing reduced coenzyme Q10 which comprises obtaining microbial cells containing reduced coenzyme Q10 at a ratio of not less than 70 mole % among the entire coenzymes Q10, optionally disrupting the cells and recovering thus-produced reduced coenzyme Q10. The present invention also relates to a process for producing oxidized coenzyme Q10 which comprises either recovering oxidized coenzyme Q10 after oxidizing the above-mentioned microbial cells or disrupted product thereof, or recovering reduced coenzyme Q10 from the above-mentioned microbial cells or disrupted product thereof to oxidize thus-obtained reduced coenzyme Q10 thereafter. According to the processes of the present invention, reduced coenzyme Q10 and oxidized coenzyme Q10 can be produced simply on the industrial scale.
Abstract:
The present invention provides a method for stabilizing reduced coenzyme Q10, which is useful as a food, nutritional product, nutritional supplement, animal drug, drink, feed, cosmetic, pharmaceutical product, therapeutic drug, prophylactic drug and the like. The present invention also provides a method of producing a reduced coenzyme Q10-containing composition which includes the co-presence of reduced coenzyme Q10 and reduced coenzyme Q9 and/or reduced coenzyme Q11.
Abstract:
The present invention provides a coenzyme Q-containing solid wherein coenzyme Q fine particles are dispersed in particles made of a physically crosslinked polymer. In addition, the present invention provides a method of producing a coenzyme Q-containing solid, which includes a step of bringing an atomized water-soluble polymer solution capable of forming a physical gel, wherein coenzyme Q is dispersed, into contact with an atomized gelling solution.In the solid of the present invention, the disintegratability is suppressed in the stomach, and rapidly disintegrated in the intestine. Accordingly, coenzyme Q is more quickly absorbed from the intestine, which in turn enhances the absorbability of coenzyme Q from the intestine. In addition, the production method of the present invention is industrially advantageous.
