A nicotine pouch composition is disclosed, the pouch composition comprising free-base nicotine and having a water content of at least 15% by weight of said pouch composition. Furthermore, an oral nicotine pouch product comprising the pouch composition and a method for manufacturing the oral nicotine pouch product is disclosed.

A producing method of a tobacco raw material comprises: a step A1 for heating a tobacco raw material in a closed space which is treated with alkali and for taking a flavor constituent released in the gas phase from the tobacco raw material to an outside of the closed space; a step B1 for allowing a first solvent to capture the flavor constituent by bringing the flavor constituent released in the gas phase in the step A1 into contact with the first solvent which is a liquid substance at normal temperature on the outside of the closed space; and a step C1 for adding the first solvent capturing the flavor constituent in the step B1 to the tobacco raw material in the closed space after the step B1.

Embodiments described herein include a method of making a tobacco extract comprising; (a) contacting tobacco with an extraction solvent such that tobacco components are extracted from the tobacco into the solvent, wherein the extraction solvent comprises a supercritical fluid; (b) separating the residual tobacco solids from the supercritical extraction solvent containing tobacco components; (c) exposing the extraction solvent containing tobacco components to conditions in a vessel at which the extraction solvent is subcritical, thereby releasing the tobacco components from the extraction solvent; and then (d) washing the vessel with an entrapment solvent which dissolves the tobacco components, wherein the entrapment solvent comprises an aerosol generating agent.

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.

The disclosure provides a composition including a filler, a lipid having a melting point of about 29° C. or above, water, and a flavoring agent or an active ingredient or both a flavoring agent and an active ingredient, which is optionally substantially free of isomalt and substantially free of tobacco material, excluding any nicotine component present, based on the total weight of the composition. The disclosure also provides compositions including a filler, a lipid having a melting point of about 29° C. or above, water in an amount of at least about 15% by weight, based on total weight of the composition, and a flavoring agent or an active ingredient or both a flavoring agent and an active ingredient.

The disclosure provides for an oral composition comprising a gel. The gel may be formed of a long chain carbohydrate, such as an alginate, that is crosslinked with a suitable crosslinking agent. Other material, such as fillers, active ingredients, flavor components, and the like may be included in the gel or otherwise combined with the gel to form an oral product. The disclosure further provides methods of preparing oral compositions.

The disclosure provides for an oral composition, the oral composition including at least one active agent, at least one filler component, and water in an amount sufficient such that the oral composition has a total moisture content of about 15% to about 30% by weight or greater based on the total weight of the oral composition.

The disclosure provides compositions and products configured for oral use, the compositions and products including a filler material, an active ingredient, and a salt component. The salt component may be present in an amount of between about 3.0% and about 4.5% by weight based on the total weight of the composition. The compositions and products as described herein may particularly exhibit a desired flavor profile.

The present disclosure provides an aerosol generating component including a substrate impregnated with two or more aerosol forming materials, including a first aerosol forming material and a second aerosol forming material, wherein the first aerosol forming material and the second aerosol forming material each have different boiling points, different vapor pressures, or both. The disclosed aerosol generating component may be utilized in aerosol delivery devices such as heat not burn (HNB) or electrically heated aerosol delivery devices.

The disclosure provides for oral compositions comprising a clarified tobacco extract and one or more filler components. In another aspect, the disclosure provides methods of preparing a clarified tobacco extract. Such methods can comprise processing a tobacco extract through at least one ultrafiltration step to provide a filtered tobacco extract and passing the filtered tobacco extract through a solution comprising one or more non-molecularly imprinted polymer (NIP) to provide the clarified tobacco extract.
