Abstract: Provided is a packaged beverage, including the following components: (A) 0.025 mass % to 0.5 mass % of a non-polymer catechin; and (B) at least one selected from the group consisting of an ?-acid and an iso-?-acid, as well as a ?-acid, in which: a mass ratio of (B2) the ?-acid to the component (B), [(B2)/(B)], is 0.01 or more; and the packaged beverage has a pH of from 2 to 5.

Abstract: Provided is a beer-taste beverage, including: (A) proline; and (B) dehydroascorbic acid, in which: a mass ratio of the component (B) to the component (A), [(B)/(A)], is from 0.001 to 1,000; the beer-taste beverage has a pH of from 2 to 5; and the beer-taste beverage has a content of ethanol of less than 1 mass %.

Abstract: Provided is a packaged tea beverage which has good flavor and is compositionally excellent in storage stability. The packaged tea beverage comprises a tea extract having a ratio of gallate-type catechins in non-polymer catechins of less than 50% by mass added to a tea extract liquid, and (A) 0.072 to 0.4% by mass of non-polymer catechins and (B) 21 to 150 ppm of gallic acid, wherein a ratio of gallate-type catechins in non-polymer catechins is 0 to 50% by mass and a ratio of epi-type catechins in non-polymer catechins is 30 to 60% by mass.

Abstract: A packaged tea beverage contains from 0.06 to 0.5 wt % of non-polymer catechins and an artificial sweetener. The content weight ratio (A)/(B) of (A) non-epicatechins to (B) epicatechins is from 0.54 to 9.0. This beverage is a highly clear packaged tea beverage, which contains catechins at a high concentration, makes the deterioration of catechins suppressed, is suited for long-term drinking, hardly changes in external appearance even during storage at a high temperature, and allows catechins to remain stable over a long term even when filled and stored in a clear package.

Abstract: A process is described for the production of a packaged green tea beverage containing non-polymer catechins at a concentration of 0.05 to 0.5 wt. %. According to the process, an aluminosilicate which has an iron release rate of not greater than 0.8 mg/kg to a catechin-containing solution is brought into contact with a green tea mixture of a green tea extract and a concentrate of green tea extract. The present invention can provide beverages, which contain catechins at high concentration and inhibit the formation of dregs during long-term storage.
