Abstract：A U-shaped fixed bed reaction system was used to conduct pyrolysis experiments on 35 types of cigar to-baccos from eight different regions at home and abroad.The produced volatiles were analayzed in real-time by photoionization mass spectrometry(PI-MS).The principal component analysis(PCA)method was used to statistically analyze the obtained MS datas.The results showed that a total of 74 shared pyrolysis products were identified in the 35 types of cigar tobaccos,mainly hydrocarbons,phenols,ketones,alcohols,esters,and nitrogen-containing substances.There were significant differences in the composition of pyrolysis products between domestic and foreign cigar tobaccos.Especially,the domestic cigar coats had a much higher content of nicotine than the foreign cigar coats,whereas the relative content of fragrant components such as methylcyclopentenone,2,3-dimethyl-2-cyclopentenone,and 2,5-dimethylcyclopentenone in the pyrolysis products of domestic cigar coats was lower than that of foreign cigar coats.The relative content of fragrant components such as 3-methylpyridine,2,5-dimethylcyclopentenone,and(+)-limonene in the pyrolysis products of domestic cigar chips was lower than that of foreign cigar chips.In addition,the characteristic pyrolysis products of cigar tobaccos screened by PCA were con-sistent with the results of routine chemical composition analysis of cigar tobaccos,confirming the accuracy of the experimental analysis results.
