摘要：用涂敷法制成含茶叶比例为0%（空白组），10%，12%，14%，16%的薄片丝，将其以10%的比例加入空白叶组中制成卷烟进行对比研究.先通过评吸比较了不同添加比例情况下的感官差异，然后通过GC＼|MS定性定量分析烟气的挥发性成分.评吸结果表明：在叶组中适当添加茶叶薄片可以改善卷烟的吸食品质.GC＼|MS 分析结果表明：添加了茶叶薄片的卷烟中，4种不同比例的茶叶添加量叶组卷烟与空白对照样各类香气成分总量相比，醛酮类、杂环类、萜烯类总含量增加都较明显，并且随着茶叶添加比例的增加，烟气粒相物香气物质含量呈增加的趋势，当添加比例为16%时各类物质含量达到最高值（分别为24.9%，27.2%，13.8%）；脂类物质变化不明显.这表明，适当添加茶叶薄片可以修饰烟气，增加烟气中致香物质的含量.

Abstract：10 % reconstituted tobacco contained tea with proportion of 0%，10%，12%，14%，16% by spreading method was added to the blank blend to make the cigarettes for comparative investigation.Firstly，the sensory difference among various adding proportion was compared by sensory evaluation，then the volatile components of smoke was analyzed by GC＼|MS qualitatively and quantitatively.The sensory results showed that appropriate amount addition of tea sheet into tobacco blending could improve the smoking quality of the cigarettes.The results of GC＼|MS analysis showed that after adding cigarettes with four different proportions，compared with various kinds of aroma compnents in blank cigarette，the contents of aldehydes and ketones，heterocyclic compounds and terpene were increased obviously.And the contents of aroma components in smoke particulate phase were enhanced with increase of tea adding proportion.At the tea adding percentage of 16%，all kinds of material content reached the highest value（24.9%，27.2% and 13.8%，respectively），but the change of esters contents was not obvious.This study indicated that tea＼|added reconstituted tobacco could modify the cigarette smoke and increase the flavor components.

0引言

茶叶具有抗氧化、降压、降血脂、降胆固醇、减肥等功效[1-2]，并且含有多种能够抗烟毒的物质[3]，因此近年来人们对茶叶及其提取物在烟草中的应用研究越来越多，以期找到一条安全、实效又能够被人们接受的除烟害新途径.许永等[4]将茶多酚添加到滤嘴中，对主流烟气进行检测后发现，烟气焦油量有所降低，烟气刺激性与杂气均减少.姜绍通等[5]将茶多酚均匀喷加到卷烟中，在离体条件下，烟气对鼠肺细胞膜脂质过氧化损伤作用减小.牛津桥等[6]将茶叶添加到再造烟叶中，发现酚类有害成分降低36%左右，并可改善吸食品质.杜萌等[7]研究发现……
