The present invention relates to a method for production of a chlorogenic
acid-containing material, including the method of contacting a coffee
bean extract (A) with a mixture of a water-miscible organic solvent (B)
and water (C) under such conditions that the weight ratio between the
components (B) and (C) obtained after the mixture is mixed with the
component (A) becomes 70/30 to 99.5/0.5; and recovering a solid portion.
According to the present invention, a chlorogenic acid-containing material
having a less disagreeable taste and less unpleasant odor can be obtained
