A tobacco substitute, in particular for use in a waterpipe (shisha), tobacco pipe or electronic cigarette, including a liquid fluid and a carrier material for the fluid is disclosed. To provide a tobacco substitute which forms a denser vapor or denser aerosol in comparison with known tobacco substitute systems, the carrier material of the tobacco substitute includes apatite.

Provided is a feature that, during storage of a heated tobacco product having a tobacco rod formed by filling the inside of wrapping paper with a tobacco filler containing a tobacco raw material and an aerosol-source material, suppresses occlusion of a heater-insertion cavity open on the distal end surface side of the tobacco rod. This heated tobacco product has a tobacco rod formed by filling the inside of wrapping paper with a tobacco filler containing cut tobacco and an aerosol-source material, and is provided with: a heater-insertion cavity that is open on the distal end surface side of the tobacco rod and extends in the axial direction of the tobacco rod, and into which a heater of a heating device is inserted; and a coating layer that is formed on the lateral periphery of the heater-insertion cavity of the tobacco rod, and suppresses occlusion of the heater-insertion cavity.

An oral tobacco composition in which sensations to the throat and esophagus that are characteristic of raw tobacco are selectively removed, and a production method thereof are provided. Provided is an oral tobacco composition in which the ratio of total content of one or more of citric acid, malic acid, succinic acid, acetic acid and formic acid to the nicotine content (A/N) is 1.30 or less.

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.

A baked item includes a tobacco and a microwave absorbing agent. The tobacco and the microwave absorbing agent are both capable of absorbing microwaves to generate heat, the microwave absorbing agent is made of a non-volatile solid material with a stable dielectric loss constant. The microwave absorbing agent is capable of stably absorbing microwaves to generate heat to heat the tobacco through thermal conduction. A method for preparing the baked item and a microwave heating method for the baked item include, the microwave absorbing agent is added into the tobacco, and the microwave absorbing agent can stably absorb microwaves to generate heat. In addition to absorbing microwaves to generate heat, the tobacco may be also heated by the microwave absorbing agent through thermal conduction, and temperature rising of the tobacco is more stable and uniform under a double heating mechanism of microwave radiation and thermal conduction.

A method of preparing a whitened tobacco material for use in a smokeless tobacco product is provided, including: (i) extracting a tobacco material with an extraction solution to provide a tobacco solids material and a tobacco extract; (ii) cooking the tobacco solids material in an alkaline sulfite cooking liquor including sulfite ions and having a pH of greater than 7 to form a tobacco pulp; (iii) bleaching the tobacco pulp with a bleaching solution to provide a bleached tobacco material; and (iv) drying the bleached tobacco material to provide the whitened tobacco material.

A consumable for an aerosol provision system comprising at least one substrate material in proximity to at least one drying agent. The drying agent preferably includes a sorbent, e.g., a desiccant, a wicking material or a mixture thereof. Also provided is a pod for an aerosol provision system where the pod contains the consumable and the consumable is configured to receive an aerosol, and use of a drying agent to increase consistency or yield of volatile compound delivery from a substrate material in an aerosol provision system.

A paste for delivery of a flavoring in water-pipe smoke is disclosed herein. The disclosed paste is produced by mixing ingredients that include granules of an inert material, an absorbent-binder, a solvent, a mist-maker, and a flavoring. The paste is configured to release the flavoring and mist-maker when heated without melting of the paste.

A method of processing pH-treated tobacco material comprising contacting at least one pH-treated tobacco material with an effective amount of one or more gases, wherein the one or more gases reduce the pH of the pH-treated tobacco material, and wherein the reduction in pH of the pH-treated tobacco material is reversible. Also provided are methods of storing pH-treated tobacco and the use of a gas to improve the shelf-life or bulk storage time of pH-treated tobacco 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.
