Determination of Amino Acidity in Japanese Sake Based on the Voltammetric Measurement of Surplus Acid by Quinone Reduction
In this paper, we propose voltammetry for determining amino acidity in Japanese sake. The measurement principle of this voltammetric method is based on a concept of acid-base back titration and a decrease of cathodic prepeak current of 3,5-di-tert-butyl-1,2-benzoquinone (DBBQ) caused by surplus HCl,...
