Study on the influence of different heating modes on aerosol release stability of heated tobacco products

Abstract The puff-by-puff release stability of aerosols generated by heated tobacco products (HTPs) is a key factor influencing consumers’ sensory experience. This study systematically investigates the effects of different heating modes and the compatibility between heated tobacco product sticks and their compatible devices on aerosol release stability. By quantifying the puff-by-puff release concentrations of key components in HTPs aerosols, the release stability is comprehensively evaluated via the relative standard deviation (RSD) and relative mean absolute deviation (RMAD). The results show that: (1) Compared with peripheral heating, central heating provides higher puff-by-puff release stability of HTPs aerosols; (2) Under the selected experimental conditions, electromagnetic central heating device exhibits good compatibility with two distinct types of HTPs sticks; (3) After optimizing the heating temperature profile, a resistive central heating device could also be adapted to the two distinct HTPs sticks, ensuring consistent and uniform puff-by-puff aerosol release. Heating modes and compatibility between stick and device are critical determinants of aerosol release stability. These findings offer theoretical and technical support for the optimization and evaluation of HTPs systems, thereby contributing to the enhancement of consumers’ sensory perception.
