Effects of cutting width of tobacco on 7 kinds of Hoffmann components of mainstream smoke

In order to explore effects of cutting width of tobacco on 7 kinds of Hoffmann components(CO, NNK, NH₃, HCN, BaP, crotonaldehyde, phenol) of mainstream smoke, the 7 kinds of Hoffmann components in mainstream smoke of cigarettes with different cutting width of tobacco were detected. The results indicated that: within the studied scope of the cutting width, with the increase of cutting width, CO, HCN and phenol in mainstream smoke decreased, NH₃ increased, NNK and BaP first increased and then decreased, while crotonaldehyde and hazard index remained unchanged; reducing the cutting width was good to selectively decreasing NH₃, BaP and crotonaldehyde, while improving the cutting width was conducive to the selective reduction of CO, HCN and phenol. To take tobacco quality and tobacco harm reduction into consideration, the best cutting width was 0.95 mm.
