A non-tea drink packed in a container which contains a purified green tea extract, characterized by: (A) containing from 0.01 to 1.0% by mass of unpolymerized catechins (B) the ratio of unepimerized compounds in the unpolymerized catechins being from 5 to 25% by mass (C) the pH value being from 2.5 to 5.1 and (D) containing from 0.0001 to 20% by mass of at least one member selected from among fructose, glucose, sucrose, high fructose corn syrup (containing less than 50% of fructose) and high fructose corn syrup (containing 50 to 90% of fructose). Thus, it is possible to provide a non-tea drink packed in a container which contains the unpolymerized catechins at a high concentration, has both of relieved astringency and appropriate sweetness/sourness with no damage in the flavor and is suitable for prolonged storage, although it contains the sweetener.一種容器裝非茶系飲料,其中添加有綠茶萃取物之純化物,且(A)非聚合物兒茶素類為0.01~1.0質量%,(B)非聚合物兒茶素類之非表體比率為5~25質量%,(C)pH值為2.5~5.1,含有0.0001~20質量%之(D)自果糖、葡萄糖、蔗糖、葡萄糖果糖液糖及果糖葡萄糖液糖中選擇之1種以上者。本發明提供一種容器裝非茶系飲料,其係以高濃度含有非聚合物兒茶素類,在不損害風味的情況下,兼顧澀味之減低與適度之甜味及酸味,儘管含有甘味料亦適於長期保存者。
