Comparative Analysis of Pyrolysates of Reconstituted Tobacco under Different Coatings Coverage Rate

[Objective] To analyze pyrolysates of reconstituted tobacco under different coatings coverage rate. [Method]Reconstituted tobacco under different coatings coverage rate of 29. 05%,33. 64%,37. 19%,41. 69%,45. 26%,48. 54% was studied by on-line pyrolysis-gas chromatography mass spectrometry( Py-GC / MS) under the conditions of simulating cigarette burning,and the qualitative and semi-quantitative results of pyrolysates were comparative analyzed. [Result] The results indicated that: types of pyrolysates were the same under different coatings coverage rate of reconstituted tobacco and the main products included nicotine,hydroxy acetone,acetic acid,hydroxy aldehyde,furfural and so on; Relative percentage of one pyrolysate was different in a certain extent under different coatings coverage rate,and the differences were especially obvious in the certain of nicotine,hydroxy acetone,acetic acid,hydroxy aldehyde and so on. [Conclusion]The study provided a theoretical reference for selecting suitable coatings coverage rate in the process of reconstituted tobacco.
