PROBLEM TO BE SOLVED: To provide a packaged caffeine-reduced green-tea beverage which has a sense of concentration due to roasted aroma, sharp taste in spite of having astringent richness and can be enjoyed even in a cooled state.SOLUTION: The packaged green-tea beverage is characterized by having a caffeine concentration of less than 90 ppm, a total sugar concentration (obtained by adding the concentration of nonreducing sugars and the concentration of reducing sugars) that falls within the range of 100-300 ppm a ratio of the concentration of the nonreducing sugar to the concentration of the reducing sugar (nonreducing sugar/reducing sugar) of 13.0-23.0 and a ratio of the concentration of ester catechins to the concentration of sugars(ester catechins/sugars) of 0.4-1.1.COPYRIGHT: (C)2011,JPO&INPIT【課題】火香(こうばしい香り)による濃度感があり、渋味のコクがありながら、すっきりとした味わいを備え、冷えた状態でもおいしく飲用できる、カフェイン量を低減した容器詰緑茶飲料を提供する。【解決手段】本発明の容器詰緑茶飲料は、カフェイン濃度が90ppm未満であり、非還元糖の濃度と還元糖の濃度とを合わせた糖類濃度が100ppm~300ppmであり、還元糖の濃度に対する非還元糖の濃度の比率(非還元糖/還元糖)が13.0~23.0であり、糖類濃度に対するエステル型カテキンの濃度の比率(エステル型カテキン/糖類)が0.4~1.1であることを特徴とする。【選択図】なし
