Abstract

See full text

The invention is to provide a method for producing a metal-supported zeolite for alcoholic beverages capable of efficiently removing unwanted components contained in alcoholic beverages to thereby reduce silver release, and the metal-supported zeolite for alcoholic beverages, and to provide a method for producing alcoholic beverages using the metal-supported zeolite for alcoholic beverages. For solution to problem, the production method for the metal-supported zeolite for alcoholic beverages of the invention is a production method for a metal-supported zeolite for alcoholic beverages for removing unwanted components contained in alcoholic beverages, and includes a first ion-exchange treatment step of processing a zeolite carrying a metal ion with an ammonium ion-containing aqueous solution to thereby exchange the metal ion in the zeolite for an ammonium ion, the zeolite containing a Y-type zeolite as the main ingredient, and a second ion-exchange treatment step of processing the ammonium ion-supported zeolite obtained in the previous ion-exchange treatment step with a silver ion-containing acidic aqueous solution to thereby exchange the ammonium ion therein with a silver ion.
