PROBLEM TO BE SOLVED: To provide a method for producing a green tea extract, in which nonpolymeric catechins are recovered efficiently while reducing caffeine from raw tea leaves and whose extract has excellent tea leaf-derived taste.SOLUTION: The method for producing the green tea extract comprises: a step A of bringing raw tea leaves into contact with a first solvent of 85°C or higher temperature for at most 4 minutes and a step B of extracting the tea leaves, which are treated after the step A, by using a second solvent. The first solvent is water containing one or more surfactants selected from sucrose fatty acid ester and polyglycerol fatty acid ester and the second solvent is water.SELECTED DRAWING: NoneCOPYRIGHT: (C)2016,JPO&INPIT【課題】生茶葉からカフェインを低減しつつ、非重合体カテキン類を効率よく回収し、かつ茶葉由来の風味の良好な緑茶抽出物の製造方法を提供すること。【解決手段】生茶葉を、85℃以上の第1の溶媒と4分間未満接触させる工程Aと、工程A後の茶葉を、第2の溶媒にて抽出する工程Bを備え、第1の溶媒がショ糖脂肪酸エステル及びポリグリセリン脂肪酸エステルから選ばれる1以上の界面活性剤を含む水であり、第2の溶媒が水である、カフェイン低減茶緑茶抽出物の製造方法。【選択図】なし
