Abstract
Official abstract text for this publication.
Provided is a method for producing a chlorogenic acids composition having a reduced caffeine content and good taste and favor, capable of efficiently recovering high purity of chlorogenic acids from a chlorogenic acids-containing composition. The method for producing a purified chlorogenic acids composition comprises a step A of bringing a chlorogenic acids-containing composition into contact with a cation exchange resin; a step B of bringing the liquid obtained in the step A into contact with an anion exchange resin; and a step C of bringing an eluent into contact with the anion exchange resin after the step B.
First claim
Opening claim text (preview).
The invention claimed is: 1. A purified chlorogenic acids composition derived from a coffee bean extract, wherein a ratio (mass ratio) of protein/chlorogenic acids is 0.1 or smaller, a ratio (mass ratio) of citric acid/chlorogenic acids is 0.05 or larger, a ratio (mass ratio) of sucrose/chlorogenic acids is 0.4 or smaller, and a content of chlorogenic acids in solids is 60 mass % or larger. 2. The purified chlorogenic acids composition according to claim 1 , wherein a ratio (mass ratio) of sucrose/chlorogenic acids is 0.1 or smaller. 3. The purified chlorogenic acids composition according to claim 1 , wherein a ratio (mass ratio) of malic acid/chlorogenic acids is 0.02 or larger. 4. The purified chlorogenic acids composition according to claim 1 , wherein the ratio of protein/chlorogenic acids is 0.01 or larger. 5. The purified chlorogenic acids composition according to claim 1 , wherein the ratio of citric acid/chlorogenic acids is 0.5 or smaller. 6. The purified chlorogenic acids composition according to claim 1 , wherein the content of chlorogenic acids in solids is from 60 to 90 mass %. 7. The purified chlorogenic acids composition according to claim 1 , wherein a ratio (mass ratio) of malic acid/chlorogenic acids is 0.3 or smaller.
