PROBLEM TO BE SOLVED: To provide a producing method of a purified chlorogenic acid-containing composition which does not lose a chlorogenic acid content and in which the color is good when diluted to be acidic beverage by controlling the chlorogenic acid content to a level proper for beverage, turbidity after production is suppressed, and caffeine is reduced.SOLUTION: A producing method of a purified chlorogenic acid-containing composition includes: a first step of dispersing or dissolving a raw material chlorogenic acid-containing composition in an organic solvent water solution； a second step of removing deposition in the dispersion or solution obtained in the first step； and a third step of contacting the solution obtained in the second step with active carbon (A) whose pore volume is 0.3-1.0 mL/g and active carbon (B) whose pore volume is larger than that of the active carbon (A). The pore volume difference [(B)-(A)] between the active carbon (A) and the active carbon (B) is 0.1-1.5 mL/g.SELECTED DRAWING: None【課題】クロロゲン酸類含量を損なうことなく、クロロゲン酸類濃度を飲料の至適濃度に希釈して酸性飲料とした場合にも色相が良好で、製造後の濁りが抑制され、かつカフェインも低減された精製クロロゲン酸類含有組成物の製造方法を提供すること。【解決手段】原料クロロゲン酸類含有組成物を有機溶媒水溶液に分散又は溶解する第１の工程と、該第１の工程により得られた分散液又は溶解液中の析出物を除去する第２の工程と、該第２の工程により得られた溶液に、細孔容積が０．３～１．０ｍＬ／ｇの活性炭（Ａ）と、該活性炭（Ａ）よりも細孔容積の大きい活性炭（Ｂ）と含む活性炭と接触させる第３の工程を備え、活性炭（Ａ）と活性炭（Ｂ）との細孔容積の差[（Ｂ）－（Ａ）]が０．１～１．５ｍＬ／ｇである、精製クロロゲン酸類含有組成物の製造方法。【選択図】なし
