Method for manufacturing refined chlorogenic acids composition

摘要

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.

主权项

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.
