Abstract
Provided is a method of producing a purified chlorogenic acid-containing composition, including: a first step of dispersing or dissolving a raw material chlorogenic acid-containing composition in an aqueous solution of organic solvent; a second step of removing a precipitate from a dispersion or a solution obtained in the first step; and a third step of bringing a solution obtained in the second step into contact with activated carbon including activated carbon (A) having a pore volume of from 0.3 mL/g to 1.0 mL/g and activated carbon (B) having a pore volume larger than that of the activated carbon (A), in which a difference [(B)−(A)] in pore volume between the activated carbon (A) and the activated carbon (B) is from 0.1 mL/g to 1.5 mL/g.
Claims16
A method of producing a purified chlorogenic acid-containing composition, comprising:
- a first step of adding together a raw material chlorogenic acid-containing composition and an aqueous solution of organic solvent to form a dispersion or solution;
- a second step of removing a precipitate from the dispersion or the solution obtained in the first step to form a solution;
- and
- a third step of bringing the solution obtained in the second step into contact with activated carbon comprising activated carbon (A) having a pore volume of from 0.3 mL/g to 1.0 mL/g and activated carbon (B) having a pore volume larger than that of the activated carbon (A) to form said purified chlorogenic acid-containing composition,
- wherein a difference [(B)−(A)] in pore volume between the activated carbon (A) and the activated carbon (B) is from 0.1 mL/g to 1.5 mL/g.
