摘 要:为确定卷烟烟气中氨的主要前体成分,采用卷烟模拟燃吸装置考察烟草中主要含氮化合物在烟草基质条件下裂解生成氨的产率,并结合烟草中含氮化合物的含量筛选出氨的主要前体成分,通过烟气实验对筛选的前体成分进行验证,确定了前体成分添加量与卷烟主、侧流烟气中氨释放量的量效关系。结果表明:烟气中氨的主要前体成分为蛋白质、天冬酰胺、铵盐和脯氨酸,对烟气中氨的贡献率分别为65.41%,15.96%,13.46%和11.26%。In order to identify the main precursors of ammonia (NH3) in cigarette smoke,the yield of NH3 from the main nitrogen-containing compounds in tobacco was studied by a smoking simulator in the presence of tobacco matrix. The main precursors were selected by referring to their contents in tobacco and validated by smoking experiments to investigate the dose-effect relationships between the yield of NH3 in mainstream and sidestream smoke and the addition amounts of precursors. The results showed that the main precursors of ammonia in cigarette smoke were protein, asparagine, ammonium salt and proline, and their contribution rates to NH3 in cigarette smoke were 65.41%, 15.96%, 13.46% and 11.26%, respectively.
