METHOD FOR MANUFACTURING REFINED CHLOROGENIC ACIDS COMPOSITION

摘要

Provided is a method for manufacturing a chlorogenic acids composition having good flavor and reduced caffeine that makes it possible to recover chlorogenic acids from a chlorogenic acids-containing composition at high purity and good yield. A method for manufacturing a refined chlorogenic acids composition having a step A for bringing a chlorogenic acids-containing composition into contact with a cation-exchange resin, a step B for bringing the liquid obtained from step A into contact with an anion-exchange resin, and a step C for bringing the supernatant into contact with an anion-exchange resin after step B.
