Embodiment 1

[0211] A tobacco starting material prepared from smoked and flue-cured tobacco materials. The tobacco material was cut to form tobacco chips having dimensions of 2.5 mm x 2.5 mm, and the tobacco chips were loaded into the extraction chamber without compression. The tobacco starting material was heated in the extraction chamber to a temperature of 130 degrees Celsius for a period of 3 hours. During heating, nitrogen flow was passed through the extraction chamber at a flow rate of about 40 liters / minute.

[0212] Volatile compounds released from the tobacco starting material during the heating step were collected by absorption into a liquid solvent formed of propylene glycol at -10°C with stirring at 750 rpm.

[0213] The nicotine composition of Example 1 is a liquid tobacco extract obtained directly from an extraction process at a temperature of 130 degrees Celsius for 3 hours. The nicotine composition provides optimized levels of desired flavor compounds such as β-damascenon...

Embodiment 2

[0215] This example provides two nicotine compositions according to the invention, both of which are concentrated tobacco extracts obtained by extraction at a temperature of 130 degrees Celsius for a period of 3 hours, followed by Obtained by a drying step to reduce the moisture level of the liquid tobacco extract to about 6%. The concentrated tobacco extract is then used directly to form a nicotine composition. In both nicotine compositions, the weight ratio of (β-ionone+β-damascenone) to (phenol) is greater than 0.25, and (furanone+(2,3-diethyl-5-methylpyrrole) The weight ratio of oxazine)*100)) to (nicotine) is greater than 5×10 -4 .

Embodiment 2a

[0217] Example 2a relates to a concentrated tobacco leaf extract derived from flue-cured tobacco material. The content of the liquid tobacco extract of embodiment 2a is as follows:

[0218] ■Nicotine: 0.53%w / w

[0219] ■ Propylene Glycol: 91.8% w / w

[0220] ■Water: 6.3% w / w

[0221] ■ Balance (including fragrances detailed in Table 1 below): 1.57% w / w

Abstract

The present invention provides a nicotine composition comprising a high ratio of desired compounds to undesired compounds. The nicotine composition comprises 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 (beta-ionone + beta-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 x 10-4. There is also provided a nicotine composition prepared by a method comprising the steps of heating a tobacco starting material at an extraction temperature of between 100 degrees Celsius and 160 degrees Celsius for at least 90 minutes; collecting the volatile compounds released from the tobacco starting material during the heating step; forming a liquid tobacco extract comprising the collected volatile compounds; and forming a nicotine composition from the liquid tobacco extract.

Description

technical field [0001] The present invention relates to nicotine compositions. Background technique [0002] Aerosol generating systems are known for delivering an aerosol to a user, the aerosol generating systems comprising a nebuliser configured to generate an inhalable aerosol from a liquid composition, such as a liquid nicotine composition. Some known aerosol generating systems include a thermal atomizer, such as an electric heater, configured to heat and vaporize a liquid composition to generate an aerosol. One popular type of electrically heated aerosol generating system is the electronic cigarette. Other known aerosol generating systems include non-thermal atomizers configured to generate aerosols from liquid compositions using, for example, impingement jet, ultrasound, or vibrating screen techniques. [0003] Nicotine compositions may be produced by an extraction process in which nicotine and other volatile flavor compounds are extracted from tobacco material and c...
