一种复合生化制剂在卷烟减害中的应用

Application of a Complex Biochemical Agent in Cigarette Harmful Component Reducing

采用超声波-有机溶剂法,从天然植物中提取多种酮、酚类及其衍生物(以KPs代表)。采用酸性丙酮法从新鲜动物血液中提取血红素后,继续处理制备成稳定的卟啉类化合物(HPs),组合成复合生化制剂,以茶末为载体,制成二元复合滤棒,用于卷烟生产。检测结果表明,与对照卷烟相比,添加该复合生化制剂的卷烟可较大幅度地降低主流烟气中多种稠环芳烃(PAHs)、烟草特有亚硝胺(TSNAs)、自由基和芳香胺等有害成分的含量。对复合生化制剂减害的作用机理进行了讨论。

Ketones, phenols and their derivatives （referred as KPs） were extracted from natural plants with ultrasonic-organic solvent technology. Stable porphyrin compounds, HPs, were made from the haematochrome extracted from fresh animal blood with acidic acetone. And then a complex biochemical agent was prepared. By taking tea powder as a carrier, a dual filter was made and applied in filter cigarette manufacturing. The test results showed that： comparing with the control, the contents of polycyclic aromatic hydrocarbons, tobacco specific N - nitrosoamines, free radicals, aromatic amines, and other harmful components in mainstream smoke of cigarettes with the dual filter were reduced significantly. The mechanism of harmful component reducing of complex biochemical agent was also discussed.
