To effectively control the content of key components in cut tobacco during the heating process, the macro type tobacco high-temperature thermal conversion thermogravimetric technology was used to investigate the influence of heating temperature on the thermal weight loss process and the thermal release characteristics of key components from cut tobacco (with a moisture content of 1. 5%) of heated tobacco products at temperatures of 180 °C, 200°C, and 220 °C. The results showed as the heating temperature increased, the changes in mass fraction of cut tobacco increased, the change rate of the mass fraction of cut tobacco increased, and the stability of the thermal weight loss process decreased. When the heating temperature was 200 °C and 220 °C respectively, the changes in mass fraction of each key component followed the order of nicotine, glycerol, moisture, and other components. Nicotine was practically completely released. Meanwhile, when the heating temperature was 180°C, the changes in mass fraction of key components of cut tobacco followed the order of nicotine, moisture, glycerol, and other components. Nicotine, glycerol, and water had higher changed in mass fraction, while other components had lower changed in mass fraction. [ABSTRACT FROM AUTHOR]
