PROBLEM TO BE SOLVED: To provide food and drink products each of which suppresses absorption of meal-derived fat, suppresses an increase in neutral fat in blood and/or prevents obesity, and to provide a lipase activity inhibitor.SOLUTION: A beverage having high lipase inhibitory activity is prepared by a preparation method which comprises the steps of: bringing an aqueous liquid, which is extracted from tea and contains polymerized catechin and non-polymeric catechin, into contact with activated carbon while keeping the aqueous liquid at 40°C or higher temperature to obtain a new aqueous liquid having the (polymerized catechin)/(non-polymeric catechin) ratio higher than that of the original aqueous liquid； and adding the obtained new aqueous liquid to an original beverage. A tea extract to be added to beverages contains the polymerized catechin of the amount so larger than that of the non-polymeric catechin that the content of the polymerized catechin becomes four times, at the least, of that of the non-polymeric catechin, but does not contain caffeine.SELECTED DRAWING: None【課題】食事由来の脂肪の吸収を抑制し、血中中性脂肪の上昇を抑え、および／または肥満を防止する飲食品、並びにリパーゼ活性阻害剤の提供。【解決手段】茶より抽出した重合カテキンおよび非重合カテキンを含む水性の液を４０℃以上に保ちながら活性炭と接触させ、元の水性液に比べて非重合カテキンに対する重合カテキンの割合が高められた液を得る工程、および得られた液を飲料に添加する工程を含む製造方法により製造されるリパーゼ阻害活性が高められた飲料。重合カテキンを非重合カテキンよりも多く含有し、重合カテキンの含量が非重合カテキンの少なくとも４倍であるり、更にカフェインを含まない、飲料添加用の茶エキス。【選択図】なし
