摘要
对不同产地及香型白酒中11种含量较高的主要风味物质进行了测定,运用化学计量学对所测得的11种风味物质含量进行包括主成分分析、聚类分析、判别分析。结果表明:不同原产地白酒中的风味物质含量有显著差异,结合化学计量学分析,建立了贵州金沙窖酒判别模型,判别准确率为100%,结果表明利用风味物质进行白酒原产地溯源研究是一种有效和准确的手段,有利于相关企业产品质量控制及产地溯源。
Contents of 11 kinds of main flavor compounds in liquor from different producing areas and flavor types were determined and measured by chemometrics methods including principal component analysis, cluster analysis, and discriminant analysis. The results showed that contents of liquor from different origin producing areas were significant different. A discriminant model for liquor from Guizhou Jinsha was established based on chemometrics analysis and its discriminant accuracy reach 100%. The results showed that it was a very effective and accurate method to study the ori- gin traceability of liquor through flavor compounds and was useful for quality control of related enterprises' products and their origin traceability.
