PROBLEM TO BE SOLVED: To provide a method for producing a purified tea extract which can recover non-polymer catechins productively without ruining the original tea flavor while efficiently removing gallic acids.SOLUTION: The method for producing the purified tea extract includes a process for bringing a tea extract into contact with at least 4-pKa weakly acid or OH-type anion exchange resin which has a gel type backbone, and an ion exchange capacity of 1.1-3 meq/mL.COPYRIGHT: (C)2012,JPO&INPIT【課題】茶本来の風味を損なうことなく、没食子酸を効率よく除去しつつ非重合体カテキン類を収率よく回収することの可能な精製茶抽出物の製造方法を提供すること。【解決手段】母体構造がゲル型であり、イオン交換容量が1.1~3meq/mLであり、かつpKa4以上の弱酸型又はOH型のアニオン交換樹脂に、茶抽出物を接触させる工程を有する、精製茶抽出物の製造方法。【選択図】なし
