PROBLEM TO BE SOLVED: To provide an enzyme-treated isoquercitrin-containing beverage generating little color change, even when being stored for a long term.SOLUTION: A beverage containing enzyme-treated isoquercitrin at a concentration of 200 mg/kg or higher is allowed to contain quinic acid so as to acquire a concentration higher than 10 mg/kg and lower than 4,000 mg/kg, to thereby adjust the mass ratio of quinic acid to enzyme-treated isoquercitrin so as to be larger than 0.05 and lower than 20.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】長期保存を行っても色の変化の少ない酵素処理イソクエルシトリン含有飲料を提供する。【解決手段】酵素処理イソクエルシトリンを200mg/kg以上の濃度で含む飲料において、キナ酸を10mg/kgより大きく4000mg/kg未満の濃度となるように含有させ、キナ酸の酵素処理イソクエルシトリンに対する質量比を0.05より大きく20未満に調整する。【選択図】なし
