METHOD FOR MANUFACTURING ACIDITY REDUCING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a relatively easy method for manufacturing an acidity reducing material which properly reduces the acidity of fermented milk products and fruit juices without adverse effect of the own taste of the material on the flavor inherent to a subject food and drink.SOLUTION: The method for manufacturing an acidity reducing material includes: a step (a) of adding water and a polar organic solvent or a mixture thereof to a roasted coffee beans for extraction treatment at 50 to 100°C for 1 to 5 hours so as to obtain a coffee extract; a step (b) of contacting the coffee extract obtained in the step (a) with a synthetic adsorbent for adsorption treatment; and a step (c) of eluting an acidity reducing material-containing coffee component adsorbed to the synthetic adsorbent with a solvent.
