Analysis of Aromatic Substances in Different Flavored Cigarette Paper by Using Headspace-Gas Chromatography-Ion Mobility Spec-Trometry (Hs-Gc-Ims)

In order to investigate the difference of aromatic substances among flavored cigarette paper, which supplied by several manufacturers with different batches, the stability of the complex system of scented cigarette paper was analyzed and evaluated. In this study, H eadspace-gas chromatography-ion mobility spectroscopy (HS-GC-IMS) was used to detect the aroma compounds of 23 flavored cigarette paper samples . Based on fingerprint analysis, the differences and changes of aroma compounds of different samples were studied in the form of data visualization. Principal component analysis, partial least squares regression analysis, cluster heatmap analysis and artificial neural network analysis were used to evaluate the stability of different cigarette paper. The results showed that: A total of 29 aromatic substances were identified from different scented cigarette paper. Through fingerprint analysis, it could be found that the aromatic substances of different cigarette paper samples were roughly the same, but not the content. The results of stoichiometry analysis showed that there were significant differences in the characteristic aroma compounds of cigarette paper from different manufacturers. HS-GC-IMS technology combined with stoichiometry method could be applied to determine the difference of aromatic substances among different flavored cigarette paper, which theoretically and technically supported the quality stability maintenance and identification of flavored cigarette paper processed in different places.
