METHOD FOR PRODUCING PURIFIED CHLOROGENIC ACID-CONTAINING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a purified chlorogenic acid-containing composition that permits efficient reduction in caffeine without imparting a chlorogenic acid.SOLUTION: The method for producing a purified chlorogenic acid-containing composition comprises: a step A of bringing a chlorogenic acid-containing composition into contact with a cation-exchange resin; a step B of bringing a liquid produced by the step A into contact with a weakly basic anion-exchange resin; a step C of bringing the weakly basic anion-exchange resin produced after the step B into contact with water of 35°C or higher; and a step D of bringing the weakly basic anion-exchange resin produced after the step C into contact with an acidic aqueous solution or an alkaline aqueous solution.SELECTED DRAWING: None
