摘要: 采用电子舌对不同品牌的啤酒及其混合样品进行识别,对所获得的数据进行主成分分析、判别因子分析和偏最小二乘回归分析。结果表明:电子舌能够有效识别不同品牌的啤酒及不同品牌啤酒的混合样品;对不同品牌啤酒的混合样品建立了偏最小二乘回归分析预测模型,电子舌响应信号和啤酒混合比例之间有很好的相关性(相关系数为0.9436),偏最小二乘回归分析模型预测误差在1.43%~3.00%之间。证明电子舌可用于啤酒的识别。

Abstract: Different beer brands and their mixtures were tested by electronic tongue and the response signals were analyzed by principal component analysis (PCA), discriminant factor analysis (DFA) and partial least-squares analysis (PLS). Individual beer brands and their mixtures were sucessfully recognized by electronic tongue. Moreover, a high regression coefficient, R2 = 0.9436, between instrumental response signal and mixed ratio of Snow,, beer and Blue Sword,, beer was found for the established PLS model with a prediction error ranging from 1.43% to 3.00%. This study demonstrates that electronic tongue is applicable for beer discrimination.

Key words: electronic tongue, principal component analysis (PCA), discriminant factor analysis (DFA), partial least-squares analysis (PLS), beer
