添加柠檬酸对卷烟七种主流烟气成分释放量的影响

Research on the Effects of Citric Acid on Deliveries of Seven Components in Mainstream Cigarette Smoke

比较了柠檬酸不同添加量对卷烟烟丝主流烟气7种成分的影响,结果表明,在考虑烟支平均吸阻、总通风率和抽吸口数对烟气成分产生影响的情况下,通过在一定比例范围（0~5%）内添加柠檬酸会导致主流烟气成分CO、HCN和B[a]P释放量的上升,另外会导致巴豆醛和NH3释放量的下降,而对于NNK来说,柠檬酸添加量的初始变化会导致其释放量上升,当达到3%后,添加柠檬酸则会导致NNK释放量逐渐缓慢下降。

By adding citric acid to cigarettes at different concentration, the experiment studied its influence to the delivery of seven components in mainstream of cigarettes smoke. The results showed that when considering the effect of process variables（Draw resistance, total ventilation rate and puff number）, the addition of citric acid（addition level 0~5%） lead to higher delivery of CO, HCN, B[a]P, and lower delivery of crotonaldehyde and NH3. The delivery of NNK increased firstly and then decreased with the increase of citric acid addition level as the peak showed when the citric acid was 3%.
