PROBLEM TO BE SOLVED: To provide a method for producing an aqueous extract of a roasted plant raw material, especially a coffee extract, having a slight aroma deterioration and improved storage stability even by heat sterilization, retort sterilization, hot vender preservation, etc.
SOLUTION: The method for reducing acetic acid of the aqueous extract of the roasted plant raw material includes carrying out permeation treatment by reverse osmosis membrane of (A) an aqueous extract obtained by extraction from a roasted plant raw material with water or (B) an aqueous extract obtained by subjecting a roasted plant raw material to steam distillation with water to give a distillate, extracting a steam distillation residue to give an extract and mixing the extract with the previously obtained steam distillation distillate and collecting a nonpermeated liquid.
