不同种类茶叶减轻吸烟危害的研究

为研究不同种类的茶叶滤嘴减轻吸烟危害的作用,将不同种类的茶叶处理后添加在卷烟滤嘴中制成茶叶滤嘴卷烟,进行感官评吸,筛选出与烟香协调的茶叶;对筛选出的茶叶滤嘴卷烟烟气中的常规成分进行检测,最后用GC/MS分析烟气化学成分。与空白对照样对比,不同茶叶滤嘴卷烟对烟碱、焦油均有降低作用,毛尖茶叶滤嘴卷烟总粒相物（TPM）、烟碱和焦油分别降低了14.35%、10.47%和14.66%;对烟气中的促癌、致癌的酚类物质的选择性截留效果比较明显,邻苯酚降低90.4%、2,4-二甲基苯酚降低84.9%;致香及有利醇和烟气的成分增加,糠醛增加207.4%、茄酮增加813.6%、巨豆三烯酮增加370%、柠檬烯增加140.4%。结果表明,茶叶滤棒能有效降低卷烟烟气中的有害成分,改善卷烟吸食品质,符合“中式卷烟”的发展方向。

Research on Different Types of Tea to Reduce Hazards of Smoking

For the purpose of studing the different varieties of tea filter tip to reduce the hazards of smoking, different types of pretreated tea leaves were added into cigarette filter to make tea filter cigarettes, then sensory evaluation smoking was carried out and the tea whose aroma is coordinate with tobacco aroma was selected. Conventional ingredients of mainstream smoke of selected tea filter cigarettes was detected, then the chemical composition of mainstream smoke was analysed by GS-MS. Compared with the blank sample, different types of tea filter cigarettes showed the effect of lowering the content of nicotine and tar, among which the notable reduction rate is tippy tea filter tip, and the reduction rate of TPM, nicotine and tar was 14.35%, 10.47% and 14.66% respectively. Also these tippy tea filter cigarettes showed an obvious effect on the selective retention of the phenols of cocarcinogenie or carcinogenic existing in cigarette smoke, the reduction rate of o-phenylphenol and 2, 4-dimethyl-phenol is 90.4% and 84.9%. Aroma and mellowing smoke components were increased, increasing rate of furfural, solanone, megastigmatrienone, and limonene were 207.4%, 813.6%, 370% and 140.4% respectively. The results showed that tea filter tip can effectively reduce the harmful conponents in cigarette smoke and improve the tasting quality of cigarettes, and consistent with the development direction of Chinese-style cigarettes.
