Abstract

A method has been developed for the simultaneous analysis of biogenic amines, amino acids, and the ammonium ion in wine and beer. Aminoenones formed by the reaction of amino acids, biogenic amines, and the ammonium ion with the derivatization reagent diethyl ethoxymethylenemalonate are separated by ...
