Abstract
Provided is a process for producing a purified chlorogenic acid-containing preparation, which is useful for the production of a chlorogenic acid-containing beverage with reduced developability of turbidity even in an acidic range. The process for producing a purified chlorogenic acid-containing preparation according to the present invention includes a first step of dispersing or dissolving a chlorogenic acid-containing composition as a starting material in the presence of acid clay or activated clay in a mixed solvent of an organic solvent and water, a second step of removing a deposit from a dispersion or solution obtained by the first step, a third step of adjusting a concentration of chlorogenic acids and pH in a solution, which has been obtained by the second step, to from 1.5 to 10 mass % and from 2 to 4, respectively, and a fourth step of separating the deposit formed in a concentration-adjusted solution obtained by the third step.
