Abstract
Extruded tobacco has its chemical composition changed during the extrusion process. Divided tobacco and ammonia are introduced into an extruder. The combination of temperatures and pressures within the extruder provides for liberation of nicotine from the tobacco. The ammonia and liberated nicotine are removed from the extruder. In addition, the ammonia and sugars within the tobacco can react to further modify the chemical composition of the tobacco. Extrudate is collected separately from the liberated materials. In such a manner, tobacco can be reformed into an extruded shape while having its chemical composition altered.
