Oral products containing a sensory agent are provided herein, wherein the sensory agent impacts the capsaicin receptors within a consumer's oral cavity, providing a spicy/hot sensation. Some such products are pouched products including an outer water-permeable pouch defining a cavity containing a composition comprising a water-soluble component capable of being released through the water-permeable pouch. Other such products include lozenges, meltable products, chewable products, and the like.

Anaerosolized formulation comprising (i) water in an amount of at least 50 wt.% based on the aerosolized formulation; and (ii) at least one active agent; wherein the aerosol has the following particle size distribution: D50 of from 2 to 6 .Math.m. A process for forming an aerosol comprising the aerosolizable formulation, an electronic aerosol provision system having an aerosolizer for aerosolizing the aerosolizable formulation for inhalation by a user, and a process for improving delivery of an aerosolized formulation to the lungs.

An aerosolized formulation comprising a vapor phase and a liquid water droplet phase, wherein the aerosolized formulation comprises (i) water in an amount of at least 50 wt. % based on the aerosolized formulation; (ii) one or more flavors; and (iii) nicotine; wherein at least 50 wt. % of the one or more flavors is present in the vapor phase. A process for forming an aerosol comprising a vapor phase and a liquid water droplet phase, an electronic aerosol provision system having an aerosolizer for aerosolizing the aerosolizable formulation for inhalation by a user, and a process for improving delivery of flavor to an aerosolized formulation.

A method includes volatilizing one or more compounds from tobacco, or reaction products thereof, into a gas stream and recovering at least one of the one or more volatilized compounds or reaction products from the gas stream. The method may be carried out in connection with a dry ice expanded tobacco (“DIET”) process where volatile tobacco compounds are recovered rather than incinerated as is typically done with current DIET processes.

A cartridge for an aerosol-generating system is provided, the cartridge containing: a first liquid formulation including at least one of water and one or more water-miscible solvents; and a second liquid formulation including one or more water-immiscible solvents having a water solubility at 20° C. of less than or equal to about 100 mg/ml, in which at least one of the first liquid formulation and the second liquid formulation comprises nicotine. An aerosol-generating system is also provided, including the cartridge; and an aerosol-generating device including one or more atomizers configured to generate an aerosol from the first liquid formulation and the second liquid formulation contained in the cartridge.

A method for preparing a tobacco flavor extract from cured tobacco materials. The tobacco flavor extract has reduced level of tobacco specific nitrosamines (TSNAs) and/or nicotine. The tobacco flavor extract is suitable for use in an electronic smoking device to provide a tobacco taste for a user of the electronic smoking device. The method preserves volatile and semi-volatile flavor components that can be released during a low-temperature vaporization process occurring in the electronic smoking device.

A producing method of a tobacco raw material containing a flavor constituent, comprises: a step A 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 B for allowing a first solvent to capture the flavor constituent by bringing the flavor constituent released in the gas phase in the step A into contact with the first solvent which is a liquid substance at normal temperature on the outside of the closed space; a step C for supplying a second solvent to the tobacco raw material in the closed space after the step A and for taking a normal component which is released as the liquid phase from the tobacco raw material to the second solvent, together with the second solvent to the outside of the closed space; and after the steps B and C, the step D for adding the first solvent capturing the flavor constituent in the step B to the tobacco raw material from which the flavor constituent is released to the outside of the closed space in the step A.

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.

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.

The present invention relates to a method of reducing the content of at least one tobacco specific nitrosamine (TSNA) precursor in tobacco, the method comprising modulating the activity or expression of at least one gene encoding a Walls are thin 1-related (WAT1-related) protein.
