- 摘要：
PROBLEM TO BE SOLVED: To provide a method for efficiently producing a high-purity chlorogenic acid by a simple method.
SOLUTION: An extracted solution of coffee is concentrated in a high concentration, extracted with an aqueous solution of ethanol or ethanol in acidity so that a high-purity chlorogenic acid is purified by a simple method and microorganism including spores of heat-resistant microorganism are substantially removed. The coffee essence concentrated in high concentration is obtained by treatment with a synthetic adsorption resin in a neutral to alkali condition, or after treatment with a synthetic adsorption resin, by desorption of adsorption part with an alkali aqueous solution or by treatment with a high cation exchange resin. A disinfected purified chlorogenic acid having high stability in a beverage, no odd taste and no offensive smell, high general purpose properties, useful as a natural antioxidant for food and beverage/health hygiene/medicine, etc., and having high purity is efficiently produced by a simple method.
