The present disclosure relates to a colorimetric aerosol detection device for detecting target compounds in an aerosol generated from an aerosol delivery device. The colorimetric aerosol detection device includes a tubular housing with a first open end (which can be configured to engage a mouthpiece of the aerosol delivery device) and a second open end (which may be configured as a mouthpiece) such that a stream of vapor can pass through the tubular housing in a direction from the first open end to the second open end. A colorimetric indicator material is located inside the tubular housing, and is configured to signal detection of a target compound in the vapor stream by a change in color visible to the user through a transparent or translucent portion of the tubular housing.

Methods of forming pyrazines from reactants derived from a plant of thespecies, including receiving an aqueous reactant solution including at least one tobacco-derived cellulosic sugar and at least one tobacco-derived amino acid, heating the reactant solution to a reactant temperature and holding the reactant solution at the reactant temperature for a reactant time to produce a reactant product including at least one tobacco-derived pyrazine, and isolating the at least one tobacco-derived pyrazine from the reactant product. Tobacco products incorporating the tobacco-derived pyrazines are also provided.
