The present invention provides a method for stabilization of reduced coenzyme Q10 characterized by concurrently containing a propylene glycol fatty acid ester in a composition containing reduced coenzyme Q10, and a composition containing reduced coenzyme Q10 and a propylene glycol fatty acid ester as essential constituting ingredients. According to the present invention, reduced coenzyme Q10, which is useful as a food, food with nutrient function claims, food for specified health use, nutritional supplement, nutritional product, animal drug, drink, feed, cosmetic, pharmaceutical product, therapeutic drug, prophylactic drug and the like can be stabilized especially without being made into a complicated composition.
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 relates to a method of conveniently and efficiently producing high-quality reduced coenzyme Q10 which is useful as an ingredient in foods, functional nutritive foods, specific health foods, nutritional supplements, nutrients, animal drugs, drinks, feeds, cosmetics, medicines, remedies, preventive drugs, etc. This method is suitable for industrial production thereof.A method of producing a reduced coenzyme Q10 which comprises reducing an oxidized coenzyme Q10 in an aqueous medium with the use of dithionous acid or a salt thereof, said reduction being carried out in the coexistence of a salt and/or under deoxygenated atmosphere, and at pH of 7 or below. Thus, the formation of the oxidized coenzyme Q10 as a by-product due to oxidation can be minimized, thereby giving reduced coenzyme Q10 having excellent qualities in a high yield.

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:
An optical measuring head which includes a cylindrical portion having a circular cross section, a plurality of light projecting fibers axially disposed in the cylindrical portion through a predetermined distance, a light receiving fiber provided along an axis of the cylindrical portion, and a convex lens formed, at its outer peripheral portion, with a light receiving face for receiving the light from the light projecting fibers and directing the light through the lens so that the light will be incident upon a flat surface of the lens adjacent an object to be measured, through an angle smaller than a critical angle whereby the light will not be reflected by the flat surface, and disposed at a position coaxial with the light receiving fiber for focusing on a forward end face of the light receiving fiber.
Abstract:
A bore measuring system to optically measure the diameter of hole on thin boards, such as printed circuit boards. The bore measuring system of the invention is so contrived as to irradiate a hole to be measured, to project the light through the hole onto the receiving surface of the image sensor and to indicate the diameter of the hole by converting the output from the image sensor, corresponding to the size of the image, into a numerical figure. Unlike the conventional methods, measurement is possible simply by irradiating the hole to be measured without inserting any pin or measuring rod of a hole gauge into the hole, and without projecting the image to be measured onto a screen. Accordingly, the operation is quite simple and the measuring time can be shortened, yet measuring errors can be avoided. Moreover, the automatic display of hole diameter in a numerical value eliminates the reading errors which often occur with conventional methods.
