GC指纹图谱在干邑白兰地真伪鉴别中的应用

Application of Gas Chromatographic Fingerprint Spectrum in Identifying True and False Cognac Brandy

通过中药色谱图分析和数据管理系统,利用峰面积夹角余弦法计算样品气相色谱图相似度,确定各干邑白兰地真酒的阈值;通过样品与真酒之间的平均相似度与真酒的阈值比较,可准确鉴别干邑白兰地酒的真伪。方法简单快速,准确性和稳定性高,可应用于干邑白兰地酒的真伪快速鉴别,从而打击制假售假行为,保护生产者和消费者的利益,保证酒类市场的健康运行。

The similarity of GC fingerprint spectrums of brandy sampels was calculated by ues of analyzing peak area angle cosine with chromatographic analysis and data management system of Chinese traditional medicine,then each true Cognac brandy threshold was determined,and the comparison of the average value of similarity of unknown brandy samples with standard cognac brandy could accurately differentiate true and false Cognac brandy.Such method had the advantages including rapid and simple operation,high accuracy and high stability.Its use to differentiate true and false Cognac brandy could crack the activities of producing fake cognac brandy,protect the interests of cognac brandy manufacturers and consumers,and ensure healthy operation of brandy market.
