         6 . The composition according to  claim 1 , wherein over 50 wt. % of the lipid is MCT caprylic acid (C8:0) based on a total weight of the lipid. 
     
     
         7 . The composition according to  claim 1 , wherein the composition further comprises maltodextrin acacia gum, silicon dioxide and/or sunflower lecithin. 
     
     
         8 . The composition according to  claim 1 , wherein the composition further comprises any of a propellant, an aerosol-forming agent, a foam-stabilizing agent, and/or a foam-forming agent. 
     
     
         9 . The composition according to  claim 1 , wherein the composition further comprises an aerosol-forming agent in a proportion of 10-80 wt.-%, preferably 30-70 wt. % of a weight of an aerosol-generating material. 
     
     
         10 . A method of preparing an aerosol-generating tobacco-containing foam or mousse, comprising the steps of:
 a. mixing an aerosol-forming agent and a foam-forming agent under heating into a mixture;   b. aerating the mixture with a gas or air for at least 5 minutes under room temperature;   c. adding to the mixture a tobacco-containing ingredient and/or an inhalable agent;   d. adding to the mixture a medium-chain triglyceride, wherein a ratio of the medium-chain triglyceride to the tobacco-containing ingredient on a dry weight basis is between 1:3 and 1:5;   e. aerating the mixture with a gas or air for at least 5 minutes under room temperature; and   f. adding a foam stabilizing agent.   
     
     
         11 . The method according to  claim 10 , wherein each step of aerating the mixture includes aerating the mixture with a heated gas or air of between 35° C. and 50° C. for at least 10 minutes. 
     
     
         12 . An aerosol-generating article comprising the aerosol-generating tobacco-containing composition according to  claim 1 . 
     
     
         13 . The composition according to  claim 1 , wherein the particulate tobacco material has a particle size of less than 50 μm. 
     
     
         14 . The composition according to  claim 1 , wherein the particulate tobacco material has a particle size of between 40 μm and 90 μm. 
     
     
         15 . The composition according to  claim 1 , wherein over 66 wt.-% of the lipid is MCT caprylic acid (C8:0) based on a total weight of the lipid. 
     
     
         16 . The composition according to  claim 1 , wherein the composition further comprises an aerosol-forming agent in a proportion of 30-70 wt.-% of a weight of an aerosol-generating material. 
     
     
         17 . The method according to  claim 10 , wherein the step of mixing includes mixing a solvent with the aerosol-forming agent and the foam-forming agent under heating into the mixture. 
     
     
         18 . The method according to  claim 10 , further comprising aerating the mixture with a gas or air after the step of adding to the mixture the tobacco-containing ingredient and/or an inhalable agent.
