Abstract: Provided is a method for producing a chlorogenic acids composition having a reduced caffeine content and good taste and favor, capable of efficiently recovering high purity of chlorogenic acids from a chlorogenic acids-containing composition. The method for producing a purified chlorogenic acids composition comprises a step A of bringing a chlorogenic acids-containing composition into contact with a cation exchange resin; a step B of bringing the liquid obtained in the step A into contact with an anion exchange resin; and a step C of bringing an eluent into contact with the anion exchange resin after the step B.
