Abstract: A Chinese yellow wine classification method is proposed based on chemometricanalysis of voltammogram of copper electrode. The main components in Chinese yellowwine are alcohol, amino acids and carbon hydrates. In strong alkaline solution copperelectrode shows rich voltammetric responses to these components. Principal componentanalysis is employed to analyse voltammetric response of copper electrode to six Chinesewine samples in strong alkaline solution. The score plots show good discrimination of thesewine samples. In order to compress the original voltammetric data, a windowed time slicingmethod is investigated in this study. It greatly reduces the input data number and theresulted PCA plot still has good discrimination ability.
