通风分配对主流烟气代表性酚类香味成分释放量的影响

Effect of ventilation on the release of typical phenolic flavor components in mainstream cigarette smoke

卷制具有不同滤嘴通风率和卷烟纸透气度的常规卷烟和细支卷烟,考查滤嘴通风率、纸通风率及通风分配对主流烟气中9种酚类香味成分释放量的影响。结果表明:1)滤嘴通风率、纸通风率与烟气中9种酚类香味成分释放量均呈显著负相关,随着通风率的增加,分子量较小的麦芽酚等的释放量降低率较高,而分子量较大的丁香酚的释放量降低率较小;2)对于常规卷烟和细支卷烟,纸通风率对烟气中9种酚类香味成分释放量的影响大于滤嘴通风率;3)滤嘴通风率、纸通风率及总通风率对常规卷烟烟气中9种酚类香味成分释放量的影响大于细支卷烟;4)在总通风率一致的情况下,高滤嘴通风率搭配低纸通风率比低滤嘴通风率搭配高纸通风率的卷烟中9种酚类香味成分释放量要高。

Normal and slim cigarettes with different filter ventilation and cigarette paper air permeability were rolled. The effects of filter ventilation, cigarette paper ventilation and ventilation distribution on nine phenolic aroma components release from mainstream cigarette smoke were investigated. The results showed the filter ventilation rate, paper ventilation rate negatively correlated to the releases of nine phenolic aroma components in cigarette smoke, and with the increase of ventilation rate, the decrease rate of maltol with caramel flavour and smaller molecular weight was higher, while the decrease rate of eugenol with smoky flavor and larger molecular weight was lower. No matter normal or small cigarettes, the paper and filter ventilation rate have different effects on the decrease of smoke composition, and the paper ventilation rate has greater influence than the filter ventilation rate. The effects of filter ventilation rate, paper ventilation rate and ventilation distribution on the release of nine phenolic aroma components in conventional cigarette smoke were greater than those in slim cigarette smoke. When the total ventilation rate was the same, the release of 9 phenolic aroma components in cigarette smoke with high filter ventilation rate and low paper ventilation rate was higher than that with low filter ventilation rate and high paper ventilation rate.
