Abstract:
To reduce the aerosol temperature from heated tobacco products, three common sugar alcohols (sorbitol, xylitol, and isomalt) were processed into granular materials, and the prepared materials were added to the filter rod of heated tobacco products. The thermal properties of the sugar alcohol materials were characterized using differential scanning calorimetry (DSC) and thermal conductivity analyzer. The aerosol temperature at the outlet of heated tobacco products was detected by a be-spoke aerosol detection device. The results showed that: 1) Under the HCI smoking regime, the heated tobacco products containing xylitol particles had the best aerosol cooling effect, and the aerosol temperature at the outlet of the heated tobacco products decreased by 7.6 ℃ compared with the control sample. 2) When the aerosol temperature at the outlet was decreased, there were significant decreases in the releases of routine aerosol components, which was due to the decrease in temperature at the outlet causing more components with lower boiling points to be filtered. 3) The filter rod with sugar alcohol granules could effectively improve the sensory evaluation of heated tobacco products.
