A pouched product adapted for release of a releasable component therefrom is provided herein. The pouched product can include a water-permeable fabric pouch formed so as to define a cavity therein, and a composition contained within the cavity of the water-permeable fabric pouch, the composition including one or more releasable components that are released from the composition under mouth conditions and that are capable of movement through the water-permeable fabric pouch. The composition includes nicotine and at least one particulate non-tobacco material. The pouched product also includes at least one capsule contained within the cavity of the water-permeable fabric pouch, the capsule having a capsule wall surrounding an inner payload comprising at least one botanical.

A nicotine composition is provided, including a non-aqueous solvent; at least 0.2 percent by weight of nicotine based on the weight of the nicotine composition; a first ratio by weight of (β-ionone+β-damascenone) to (phenol) of greater than 0.25; and a second ratio by weight of (furaneol+(2,3-diethyl-5-methylpyrazine)*100)) to (nicotine) of greater than 5×10.sup.−4. A cartridge including the nicotine composition, and a method of preparing the nicotine composition, are also provided.

Methods of forming pyrazines from reactants derived from a plant of the Nicotiana species, 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.

A method of isolating compounds from a tobacco-derived black liquor, including receiving a black liquor from a pulping process of an input material comprising a plant of the Nicotiana species, treating the black liquor with an acid to lower the pH of the black liquor to about 7 or lower in order to produce a precipitate and an acidified black liquor, separating the precipitate and the acidified black liquor, extracting the acidified black liquor with an organic solvent in order to produce an organic layer extract and an aqueous layer extract, and separating the organic layer extract and the aqueous layer extract.

Processes for recovering sugars and nicotine from a tobacco biomass include feeding a biomass of tobacco plants and subcritical water to a reactor, hydrolyzing the biomass of tobacco plants with the subcritical water at a temperature between about 150° C. and 305° C. and recovering a liquid product and a solid product from the reactor, wherein the liquid product contains water-soluble sugars and nicotine.
