The disclosure provides for oral compositions and products that can have a relatively low water content and/or a relatively low water activity. Such compositions and products can comprise at least one active ingredient, a filler/carrier component, and water in an amount of less than 10% by weight, based on the total weight of the composition. Further, the compositions and products can have a water activity of about 0.85 or less.

The disclosure provides liquid compositions configured for oral use, the liquid composition comprising water in an amount of about 40% by weight or higher, based on total weight of the composition, a flavoring agent or an active ingredient or both a flavoring agent and an active ingredient, and one or more additional components selected from the group consisting of sweeteners, humectants, and alkali metal salts, wherein the composition has a water activity (Aw) of about 0.85 or lower. The liquid compositions are generally suitable for spraying into the oral cavity.

A method of manufacturing a flavor source includes: a step A of adding a basic substance to a tobacco raw material; a step B of heating the tobacco raw material added with the basic substance and releasing an inhaling flavor component into a vapor phase from the tobacco raw material; a step C of collecting the inhaling flavor component released into the vapor phase in the step B; a step D of washing a tobacco residue being the tobacco raw material obtained after the inhaling flavor component is released in the step B, with a washing solvent; a step E of pulverizing or cutting the tobacco residue obtained after being washed in the step D; and a step F of adding the inhaling flavor component collected in the step C to the tobacco residue obtained after pulverized or cut in the step E.

A nicotine formulation for an aerosol-generating system is provided, the nicotine formulation including: one or more water-miscible polyhydric alcohols, the nicotine formulation having a water-miscible polyhydric alcohol content of greater than or equal to about 40 percent by weight, the nicotine formulation being solid at 25° C. or having a viscosity at 25° C. of greater than or equal to about 100 Pa.Math.s, the one or more water-miscible polyhydric alcohols including glycerine and propylene glycol, and a ratio of the weight percent glycerine content to the weight percent propylene glycol content of the nicotine formulation is greater than or equal to about 1.5. An aerosol-generating article and an aerosol-generating system are also provided.

A method for reducing the content of nitrosamines in a tobacco material is provided herein, the method involving the steps of contacting a tobacco material with a treatment solution so as to form a treatment composition containing, in addition to the tobacco material, an acid, a complexing agent, a solvent, and, optionally, a salt, at a pH of about 5.5 or less, to obtain a tobacco material having a tobacco-specific nitrosamine content that is lower than the initial tobacco-specific nitrosamine content. The method can optionally include further processing of the tobacco material. Smoking articles and other tobacco products incorporating such treated tobacco materials are also provided.

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 method of preparing a whitened tobacco material is provided, including: (i) extracting a tobacco material with a first extraction solution to provide a tobacco solids material and a tobacco extract; (ii) cooking the tobacco solids material in an alkaline cooking liquid comprising sodium sulfide and having a pH of greater than 11 to form a tobacco pulp; (iii) treating the tobacco pulp with an acid to lower the pH of the tobacco pulp and provide a neutralized tobacco pulp; (iv) extracting the neutralized tobacco pulp with a second extraction solution comprising at least one chelating agent to provide an extracted tobacco pulp; and (v) bleaching the extracted tobacco pulp with a bleaching solution to provide a whitened tobacco material.

The embodiments disclose a method for processing plant-based material for smoking products including maintaining the plant-based material submerged within a liquid medium in a container while the liquid medium is being boiled, removing the boiled plant-based material from the container, and drying the boiled plant-based material, the drying comprising directing negative air ions towards and through the boiled plant-based material to at least partially neutralize odor and/or taste, a plant-based material product produced by the method is also provided as a smoking product including the plant-based material product or the plant-based material product combined with a treatment material such as CBD, CBG, a flavoring agent and combinations thereof, also provided is a plant-based material product comprising boiled plant-based material dried while being exposed to negative air ions, and a smoking product such as a cigarette incorporating the plant-based material product or the plant-based material product combined with a treatment material.

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.
