Abstract

PURPOSE:To produce a colorless or light-colored drink without deteriorating the original taste of the base drink, by contacting a dark-colored drink with a specific polymeric resin, thereby adsorbing and removing the polyphenols from the drink. CONSTITUTION:Coffee, black tea, cola or various other dark-colored drinks containing polyphenols such as catechin, chlorogenic acid, anthocyanin, flavonoid, etc., or stock liquid of the drink are made to contact with a polymeric resin selected from polyamide, polyethylene and polyvinyl pyrrolidone to effect the adsorption and removal of the polyphenols from the drink or the stock liquid of the drink. The produced drink has the same taste and flavor as the untreated drink and can be stored for a long period in a cold place without causing precipitation of polyphenols.
