PROBLEM TO BE SOLVED: To provide a packaged green tea beverage having a deep taste in which sweetness and astringent are harmonized by application of natural sweetness and suppressing astringent, while maintaining a basis of a natural taste of green tea beverage.SOLUTION: There is provided a packaged green tea beverage configured so that, tannin density is equal to or less than 100 mg/100 mL, caffeine density is equal to or less than 2 mg/100 mL, in the green tea beverage, in which, hexanoic acid is included so that hexanoic acid density in the green tea beverage is 29-320 ppb, for applying natural sweetness and for suppressing astringent, thereby providing the packaged green tea beverage having a deep taste in which sweetness and astringent are harmonized. In the packaged green tea beverage in which, tannin density and caffeine density in the green tea beverage are adjusted to become in a specific range, hexanoic acid is added and blended, and the hexanoic acid density in the green tea beverage is adjusted to become in a specific range, for applying natural sweetness and suppressing astringent, for providing the packaged green tea beverage having a deep taste in which the sweetness and the astringent are harmonized.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】緑茶飲料本来の味のベースを保持しつつ、自然な甘味の付与と、苦渋味の抑制によって、甘味及び苦渋味を調和した味わいの深い容器詰緑茶飲料を提供すること【解決手段】緑茶飲料中、タンニン濃度が100mg/100mL以下、カフェイン濃度が2mg/100mL以上に調整された、容器詰緑茶飲料において、緑茶飲料中のヘキサン酸濃度が、29~320ppbとなるように、ヘキサン酸が含有されていることを特徴とする自然な甘味の付与と、苦渋味の抑制によって、甘味及び苦渋味を調和した味わいの深い容器詰緑茶飲料を提供する。本発明は、緑茶飲料中のタンニン濃度及びカフェイン濃度を特定範囲に調整した、容器詰緑茶飲料において、ヘキサン酸を添加、配合して、緑茶飲料中のヘキサン酸濃度を特定の範囲に調整することにより、自然な甘味の付与と、苦渋味の抑制によって、甘味及び苦渋味を調和した味わいの深い容器詰緑茶飲料を提供する。【選択図】なし
