[ Method] The release amount of seven kinds of Hoffmann com-ponents from the mainstream smoke of cigarettes which were prepared from the cut tobacco treated under different expansion temperatures was de-termined. [ Result] Under the same expansion model, the temperature change produced certain impact on the release amount of NH~, phenol and BAP, while had no significant influence on that of CO, NNK, HCN and crotonaldehyde; under CO2 expansion model, the release amount of seven Hoffmann components was small; the reduction of expansion temperature was good for lowering the harmful index of cigarette to a certain extent. [ Conclusion] The study provides basis for optimizing the technical parameters of producinq less harmful cigarette.展开更多
