gareto body ratio in non polymer katekin reducing, you improve the presenting taste of the spirit manufactured tea extract. Production method of the spirit manufactured tea extract of this invention after hydrolysis processing, makes the brown extract the active carbon adsorb, next makes the basic aqueous solution or the organic solvent aqueous solution contact and features that non polymer katekin are made to liquate.非重合体カテキン類中のガレート体率を低減化して精製茶抽出物の呈味を改善する。本発明の精製茶抽出物の製造方法は、茶抽出物を加水分解処理した後、活性炭に吸着させ、次いで塩基性水溶液又は有機溶媒水溶液を接触させて非重合体カテキン類を溶出させることを特徴とする。
