【摘要】 对添加4种卷烟纸助剂乙酸钾、柠檬酸钾、富马酸钾和草酸钾的卷烟纸,采用热裂解-气相色谱-质谱技术探索助剂对卷烟的降焦、降一氧化碳(CO)的机理。研究表明,在助剂添加量为2.0%(对绝干浆)的条件下,用添加了上述助剂生产的卷烟纸生产的卷烟,其焦油含量分别降低了10.91%、13.94%、16.36%和13.33%;一氧化碳(CO)含量分别降低了12.57%、13.17%、17.96%和14.37%。卷烟感官评吸结果表明,卷烟纸助剂柠檬酸钾、富马酸钾对卷烟吸味有一定的提升作用。采用热裂解对使用不同助剂的卷烟纸进行研究,在一定程度上解释了卷烟纸助剂降CO、降焦以及对卷烟吸味影响的原因。更多还原

【Abstract】 Four cigarette additives of potassium acetate,potassium citrate,potassium fumarates and potassium oxalate have been selected in this research to investigate their effects on harm reduction.The results showed that when 2.0% additives was added into cigarette papers respectively,the tar in the main stream smoke decreased by 10.91%,13.94%,16.36% and 13.33%,and CO decreased by 12.57%,13.17%,17.96% and 14.37% respectively.The sense evaluation indicated that potassium citrate and potassium fumarates have positive effects on cigarette taste.The mechanisms of harm reduction and taste improvement have been elucidated to a certain extent through the pyrolysis analysis of cigarette papers added the different additives.更多还原
