摘要
Abstract
To investigate the influence of heating temperature on tobacco decomposition, thermogravimetric analysis coupled with cold trap and gas chromatography-mass spectrometry(GC/MS)was used to study the thermal decomposition process of tobacco materials, including flue-cured, burley, oriental, sun-cured tobacco and paper based reconstituted tobacco in 10% oxygen and 90% nitrogen atmosphere. Released components from thermal decomposition were trapped by a cold trap linked to a pyrolyzer and qualitatively analyzed by GC/MS. The results showed that: 1)Surface components in cut-tobacco decomposed initially at 150 ℃, carbonized at 300 ℃ followed by aroma component release. 2)The release of nicotine increased with the rise of temperature, and tended to be stable at or above 250 ℃. 3)Decomposition components from different tobacco materials were different in chemical compositions. The acidic/basic component ratio in the emissions was 0.2(the lowest)for sun-cured tobacco and 2.6(the highest)for paper base of reconstituted tobacco.关键词
