Abstract: A method of forming a shaped foam containing a tobacco ingredient containing agent includes a first step of combining and mixing the tobacco ingredient containing agent and a foam forming agent to obtain a first mixture; a second step of adding an aerosol forming agent and optionally a solvent and/or at least one non-tobacco flavoring agent to the first mixture to obtain a second mixture; a third step of adding a foam stabilizing agent to the second mixture to obtain a third mixture; and extruding the third mixture to produce a shaped foam, wherein at least the second and the third step are carried out inside an extruder. A shaped foam containing a tobacco ingredient containing agent produced by the method, and a device for producing shaped foam containing a tobacco ingredient containing agent are also provided.
