Abstract：In order to investigate the new way to reduce tar and harmful components in cigarette,subcritical extraction technology was used to treat tobacco leaf.The extraction conditions were optimized.The deliver-ies of the harmful components,tar,nicotine in mainstream smoke of cigarettes prepared with the extracted cut tobacco were determined,the chemical components,processability and sensory quality were also evalua-ted.The results indicated that:microwave wall-breaking treatment,dimethyl ether extraction 2 times,each time 30 min was the optimal extraction method;the deliveries of tar and nicotine were significantly lowered than the control sample with the decreased rate at 33.4% and 62.2% respectively;the structure of extrac-ted cut tobacco remained no obvious change;in the seven harmful components,the release amount of phe-nol,HCN,NH3 ,CO and B[a]P were decreased.The harmful index reduced by 3.87;the sensory evalution of extracted cut tobacco was found to be superior to the controller in tender degree,aftertaste and stimula-tion.It was characterized by tenderness and sweetness.The study showed that subcritical extraction technol-ogy provides a potential way of reducing tar and harmful components in tobacco leaf.
