- 摘要：
PROBLEM TO BE SOLVED: To provide a method for producing a purified tea extract by which the recovery of nonpolymer catechins is improved while reducing the amount of a used organic solvent.
SOLUTION: The method for producing the purified tea extract includes an adsorption step for adsorbing the nonpolymer catechins contained in a tea extract by bringing the tea extract into contact with a synthetic adsorbent having a fine and uniform particle diameter, and an elution step for eluting the nonpolymer catechin by bringing an aqueous solution of the organic solvent into contact with the synthetic adsorbent.
