茶叶再造烟叶对卷烟烟气成分的影响

以茶叶为添加物,将添加不同比例茶叶的再造烟叶加入叶组制成卷烟样品,用吸烟机抽吸样品,再用同时蒸馏萃取法（SDE）进行提取,并用GC-MS进行烟气成分分析。结果表明,与空白对照样对比,含不同比例茶叶的再造烟叶叶组卷烟中,致香成分均有不同程度的增加：羧酸类、杂环类、醛酮类、酯类和醇类含量增加,分别平均增加175.08%、58.46%、48.57%、40.83%和16.47%;随着茶叶添加比例的增加,杂环类、酯类、羧酸类和醛酮类致香物质含量呈逐渐增加的趋势。检测到主要有害成分共13种,分别有不同程度的降低,添加10%、12%、14%、16%茶叶的样品中总量分别降低19.0%、40.7%、10.6%、17.1%。

Effects of Tea Reconstituted Tobacco on Smoke Constituents

The smoke chemical constituents from blended tobacco cigarette to which reconstituted tobacco containing different proportion of tea dust were added and smoked by smoking machine,extracted through the simultaneous and extraction method(SDE),and then investigated by gas chromatography-mass spectrometry(GC-MS).Compared with the blank control sample,it showed that the flavor components in blended tobacco containing different proportion of tea dust were increased in different degrees: the total contents of carboxylic acids,heterocyclics,carbonyls,esters and alcohols increase 175.08%,58.46%,48.57%,40.83% and 16.47% respectively on average,and the contents of heterocyclics,esters,carboxylicacids and carbonyls were increased as the increasing of the adding proportion of tea dust.The 13 main harmful components were detected totally and the total contents were decreased 19.0%,40.7%,10.6% and 17.1% in the samples that added 10%,12%,14% and 16% of tea dust respectively.
