An aerosol-generating tobacco-containing composition, preferably provided in a form of a foam or mousse, and an aerosol-generating article including the composition, are provided. The composition includes particulate tobacco material and lipid, wherein the lipid is medium-chain triglyceride, and a ratio of the medium-chain triglyceride to the particulate tobacco material on a dry weight basis is between 1:3 and 1:5.

An improved aeration of foam as well as a method of forming the foam for an aerosol-generating article includes (a) mixing an aerosol-forming agent, a foam-forming agent and optionally a solvent and/or at least one non-tobacco flavoring agent, preferably under heating; (b) adding to the mixture a tobacco-containing agent and/or an inhalable agent; (c) adding a foam-stabilizing agent; (d) cooling of the mixture; wherein the mixture is aerated after the adding of the foam-stabilizing agent and/or after cooling of the mixture, and wherein sodium bicarbonate is added to the mixture before cooling of the mixture, wherein the sodium bicarbonate content is less than 1 wt. % based on the total weight of the foam.

An aerosol-generating article is provided, including: an aerosol-generating substrate including a homogenised ginger material including ginger particles, an aerosol former, and a binder; at least 10 micrograms of [6]-gingerol per gram of the substrate, on a dry weight basis; at least 90 micrograms of [10]-gingerol per gram of the substrate, on a dry weight basis; at least 70 micrograms of [10]-shogaol per gram of the substrate, on a dry weight basis; at least 30 micrograms of [8]-shogaol per gram of the substrate, on a dry weight basis; and at least 80 micrograms of [6]-shogaol per gram of the substrate, on a dry weight basis. An aerosol-generating substrate, an aerosol-generating system, and an aerosol produced upon heating of an aerosol-generating substrate, are also provided.

A process is disclosed for incorporating additives into aerosol-producing substrates. During the process, an additive is incorporated into an infusing liquid. An aerosol-producing filler is submerged in the infusing liquid and the resulting mixture is subjected to reduced pressures that cause the infusing liquid to infuse into the material. The material is dried leaving behind the additive in a controlled amount and uniformly dispersed throughout the material. In one application, cannabidiol is incorporated into a tobacco filler or a hemp filler.
