Abstract
Provided is a purified chlorogenic acid-containing composition, having: a content of a chlorogenic acid in solids of from 10 mass % to 70 mass %; a “glucose/chlorogenic acid” mass ratio of from 0.1 to 0.9; a “caffeine/chlorogenic acid” mass ratio of 0.05 or less; and a pH of from 1 to 5.

2 more elements
A method of producing a purified chlorogenic acid-containing composition, comprising:
- a first step of bringing a chlorogenic acid-containing composition into contact with at least one of adsorbent selected from the group consisting of activated carbon, acid clay, and activated clay;
- and
- a second step of subjecting the chlorogenic acid-containing composition after the contact with the adsorbent to at least one selected from the group consisting of the following steps (A) and (B) under an acidic condition:
- (A) a step of concentrating the chlorogenic acid-containing composition by 6 times or more at a temperature of from 20° C. to 70° C.;
- and
- (B) a step of adding glucose to the chlorogenic acid-containing composition.
