采用PVA-H3BO3交联法对茶叶粉末进行包埋固定化,制成的茶叶包埋颗粒作为净化材料填装到过滤腔中,制得茶叶包埋颗粒过滤器。使用该过滤器抽吸卷烟,进行感官质量评价,并对烟气常规成分及化学成分进行检测分析。结果表明,与空白对照样对比,茶叶包埋颗粒可有效降低刺激性,增加烟香,改善余味;烟气总粒相物和焦油量有所降低,分别降低5.80%、6.04%,烟碱变化不明显;烟气中致香成分、增加烟气浓度的成分及醇和烟气的成分均有不同程度的增加,如苯甲醇、二氢猕猴桃内酯、2-乙酰基呋喃、5-甲基糠醛、巨豆三烯酮分别增加188.10 %、151.65%、80.11%、63.97%、57.73%,而酚类等有害物质明显减少,如邻甲酚、2,3-二甲基苯酚、苯乙腈、2-甲基芴分别降低38.47%、24.46%、60.09%、65.40%。
By using the PVA-H3BO3 cross-linking method to make tea embedding particles by imbedding the tea powder, using the cigarette holder which uses these particles as filter material to assess the smoking quality and investigating the conventional ingredients and chemical components of mainstream smoke. Compared with the blank control sample, the results indicated that the tea embedding particles could decrease irritancy, enhance cigarette flavor and improve aftertaste obviously. Total particulate matter (TPM) and tar were decreased 5.80%, 6.04% respectively, nicotine did not change significantly. The flavor, enhancing smoke concentration and mellowing smoke components were increased in different degree, such as benzyl alcohol, dihydro-actinidiolide,1-(2-furanyl)-ethanone,5-methyl- 2-furancarboxaldehyde, megastigmatrienone were increased 188.10%, 151.65%, 80.11%, 63.97% and 57.73% respectively, while the harmful components, such as 2-methyl-phenol, 2,3-dimethyl-Phenol, benzylnitrile and 2-methyl-9H-Fluorene decreased significantly, were reduced 38.47%、24.46%、60.09%、65.40% respectively.
