摘要
选择红花大金元B3F、C3F、X2F烟叶,对打叶复烤各工序卷烟主流烟气氢氰酸、苯并[a]芘和巴豆醛释放量进行研究。结果表明:各工序上部烟叶卷烟样品的HCN释放量最高,下部烟叶的最低,一润工序较处理前较大幅度提高了上部烟叶氢氰酸释放量;二润工序与一润工序相比,下部烟叶苯并[a]芘释放量降低9.36%;复烤工序与二润工序相比,下部烟叶巴豆醛释放量降低14.96%,中部烟叶苯并[a]芘释放量降低17.29%。综合结果,上部烟叶各工序间样品的主流烟气3种物质的变化强度都明显高于下部烟叶。
Flue-cured tobacco leaves from cultivar Honghuadajinyuan graded B3F（upper leaves）, C3F（middle leaves） and X2F（lower leaves） were chosen to investigate the effects of various threshing and redrying processes on the delivery of HCN, benzo[a]pyrene and crotonaldehyde in cigarette mainstream smoke. The results showed that the HCN delivery from upper leaves was the highest, while the lowest from the lower leaves. The HCN delivery of upper leaves got substantial increase after the first conditioning process, compared to which the benzo[a]pyrene delivery of lower leaves was reduced by 9.36% after the second conditioning process. The crotonaldehyde delivery of the lower leaves was reduced by 14.96% and the benzo[a]pyrene delivery of middle leaves was reduced by 17.29% after redrying process compared to those after the second conditioning process. The change intensity of the delivery of 3 components from the upper leaves was significantly bigger than that from the lower leaves after each process step.
