Abstract
Chinese kaoliang spirit (CTKS) is a popular liquor within the Yue nation with a history dating back 2500Â years. However, fraudulent practices have occurred during its commercialization, including the production and sale of adulterated spirits that have been aged differently. Here, a gas-chromatography-flash electronic nose technique was combined with chemometric analysis to develop a rapid method for the discrimination of CTKS of various ages. Models for discrimination were developed using principal component analysis and discriminant factor analysis. We also investigated the volatile organic compounds in CTKS to determine differences between samples of different ages. The electronic nose technique combined with chemometric methods may be used for fingerprinting to authenticate CTKS and protect the quality and prestige of this product.
