Abstract:
In order to investigate the feasibility of the extract from Cyclocarya paliurus as an additive in cigarettes,the volatile aromatic components were analyzed by gas chromatography-ion mobility spectrometry(GC-IMS),and C.paliurus extract was pyrolyzed to simulate cigarette smoking by TGA-GC/MS.The cracking products of C.paliurus were analyzed in a nitrogen environment,and the possible cracking mechanism of the products was reasonably speculated.The results showed that aldehydes,alcohols,and ketones were the primary volatile aroma components of the C.paliurus extract,comprising 62.28%of the total aroma components.The cracking products of C.paliurus extract varied greatly under different temperature conditions.A total of 79 compounds were identified at 200,360,and 440℃,among which 24 aromatic components were clearly identified as having significant effects on cigarette style,including aldehydes,ketones,alcohols,phenols,furans,benzene series,and other natural aromatic substances.Among them,phenols containing a high concentration are mainly formed by compounds containing the structure of guaiacol unit and eugenol unit by side chain cleavage,demethylation,demethoxylation,dehydration,etc.Furan and its derivatives are mainly formed by glycosides or glycoside compounds by breaking glucoside bonds and dehydration.
