Subcritical extraction technology was applied to cut-tobacco. Its changes of process ability, chemical components, volatile organic compounds (VOCs), pesticides residue, main stream smoke, and sensory quality of cigarette after processing were investigated. Results indicated that subcritical extraction weakened the processing-resistance capability of cut-tobacco, but didn't affect its usability, and there were no organic solvent residues in the cut-tobacco. No pesticide residue was found in samples from dimethyl ether treatment group and the removal rate in butane treatment group was 50.0%, 43.8% and 70.0%, respectively. In dimethyl ether and butane treatment group, tar delivery in mainstream smoke decreased by 12.7% and 8.5% respectively, and water, CO and nicotine also declined to some extent. Sensory evaluation results, including tender degree, aftertaste and irritation, in two treatment group, were both better than control. Deliveries of phenol, HCN, ammonia, CO and benzopyrene in mainstream smoke of dimethyl ether treatment group reduced by 19.7%, 18.8%, 33.3%, 19.5% and 25.2% respectively, and NNK and crotonaldehyde showed no obvious change. The hazard index was reduced from 13.5 to 10.9. Subcritical extraction technology was proved to be applicable in reducing tar delivery and other hazards in cigarettes.
