Abstract: There is a demand for the development of a novel beverage containing an alternative sweetener to sugar. The present invention provides a beverage containing 0.1-25 w/v % of D-arabinose.

Abstract: A differential gear mechanism in which when a plurality of contact lines between a gear tooth and a pinion tooth is defined on either a tooth surface of the gear tooth of a crown gear or a tooth surface of the pinion tooth of a pinion gear at a predetermined angle around an axis of the pinion gear, and the plurality of contact lines and a center line of a pinion tooth bottom surface of the pinion gear are projected onto a plane, including an axis of a pair of the crown gears, around the axis of the pinion gear, the center line of the pinion tooth bottom surface projected onto the plane includes an inclined line passing through a range between two of the contact lines which are selected from the plurality of contact lines projected onto the plane and by which a contact ratio is 1.0 or higher.

Abstract: Provided is a method of producing a liquid mineral extract containing an abundant amount of potassium that is a mineral component extremely important for humans. A mineral is extracted from activated carbon of a plant-derived raw material using an aqueous solvent.

Abstract: Provided is a liquid mineral concentrate composition that can be added to water, food, drink, or the like to improve the flavor and function thereof. The liquid mineral concentrate composition contains potassium ions the concentration of which is the highest of the metal ions present in the liquid mineral concentrate composition.

Abstract: Provided is a potable water that is safe, good-tasting, and beneficial for the health of a human body. Provided is a mineral-containing aqueous composition for oral ingestion, having a potassium ion concentration of 20 ppm or more.

Abstract: A differential gear mechanism in which when a plurality of contact lines between a gear tooth and a pinion tooth is defined on either a tooth surface of the gear tooth of a crown gear or a tooth surface of the pinion tooth of a pinion gear at a predetermined angle around an axis of the pinion gear, and the plurality of contact lines and a center line of a pinion tooth bottom surface of the pinion gear are projected onto a plane, including an axis of a pair of the crown gears, around the axis of the pinion gear, the center line of the pinion tooth bottom surface projected onto the plane includes an inclined line passing through a range between two of the contact lines which are selected from the plurality of contact lines projected onto the plane and by which a contact ratio is 1.0 or higher.

Abstract: The present invention addresses the problem of providing a beverage which, although containing chitosan, is prevented from clouding. The present invention provides a beverage containing specific amounts of chitosan and vitamin C.

Abstract: An object of the present invention is to provide a tea beverage which comprises a chitosan but is prevented from getting cloudy. According to this invention, there is provided a non-fermented or semi-fermented tea beverage comprising a chitosan having a molecular weight of not more than 7 kDa at a concentration of not more than 200 ppm.
