Abstract: | [Objective]The research aimed to explore the new methods for the quality evaluation of tobacco flavor.[Method]The gas chromatography/mass spectrometry(GC/MS)fingerprint spectum of tobacco flavor was established to calculate correlation coefficient,cosine of the included angle and extent similarity of 19 batches of tobacco flavor B# samples.Then the clustering analysis was adopted.[Result]In combination of the extent similarity and the clustering analysis could effectively reflect the overall differences between samples.[Conclusion]This method was accurate and reliable,and it was an apparent,credible and efficient method for quality evaluation of tobacco flavor. |
