Abstract

Objective: Studied the smoke emission characteristics of central electric heating cigarette. Methods: The release amount and stability of total and puff-by-puff mainstream smoke were investigated by taking seven domestic cigarettes (Cigarettes A-G) and one foreign cigarette (Cigarette H) as the samples. The factors that may influence smoke release stability were discussed. Results: ① The transfer ratios of nicotine and glycerol in Cigarettes H were the lowest; ② The smoke release stability of Cigarettes H was the highest; ③ The release behavior of TPM, nicotine and glycerol on a puff-by-puff basis all showed increase-decrease trend with the increase of puff sequence, which was different from the traditional cigarettes under ISO regime; ④ The tobacco retreated phenomenon when cigarette was inserted into its heating device had negative effect on the smoke release stability. Conclusion: The smoke release stability could be improved by reducing the tobacco retreated phenomenon of central electric heating cigarette.
