Abstract:

Following the widespread improving living standard, the consumption of white spirit is having a great increase day by day. Because of the spirit vary in quality, a reliable scientific method is desired to distinguish genuine from sham white spirit. The more common method for determination of spirit is to use sense organ by judge. The results are often effected with the judge's experience, health situation and environmental conditions. In our research, the micro-components with a special flavor of ten samples of the 38% alcohol Jiannanchun are determined by capillary GC, and the quality model are established by mathematical cluster analysis. It was verified with known genuine from sham white spirit,the results are satisfied us.
