Abstract

Described herein is a composition for use in a device for generating an inhalable medium, the composition comprising (i) 50-85% by weight of air-cured and/or fire-cured tobacco (ii) 0-50% by weight of flue-cured and/or sun-cured tobacco that has not been subjected to any further treatment which affects the flavor properties of tobacco, and (iii) 0-50% by weight of flue-cured and/or sun-cured tobacco that has been further treated to enhance the flavor properties of tobacco.

First claim

The invention claimed is:

1. A composition for use in a device for generating an inhalable medium, the composition comprising:
50-85% by weight of a first tobacco component that has been dark air-cured, dark fire-cured, or both dark air-cured and dark fire-cured;
5-50% by weight of a second tobacco component that has been flue-cured, sun-cured, or both flue-cured and sun-cured, said second tobacco component having not been subjected to any flavor treatment beyond flue-curing and/or sun-curing, and
5-50% by weight of a third tobacco component that has been flue-cured, sun-cured, or both flue-cured and sun-cured, wherein only the third tobacco component has been subjected to a flavor enhancing Maillard reaction, the Maillard reaction enhancing the flavor properties of the third tobacco component, and
wherein the first, second and third tobacco components are mixed together to form a porous tobacco composition with the Maillard reaction occurring prior to mixing the third tobacco component with the first and second tobacco components.

2. The composition of claim 1 , wherein the further treatment comprises producing the third tobacco product by the process of providing a tobacco material within a moisture-retaining material and exposing the tobacco material to a processing temperature at least about 45° C. wherein the tobacco material has a packing density on a dry weight basis of at least 200 kg/m 3 at the start of the process and has a moisture content of between about 10% and 23% before and during the treatment.

3. The composition of claim 1 wherein the composition comprises:
50-65% by weight of the first tobacco component,
35-50% by weight of the second tobacco component, and
5-15% by weight of the third tobacco component.

4. The composition of claim 1 wherein the composition comprises:
50-65% by weight of the first tobacco component,
10-30% by weight of the second tobacco component, and
20-40% by weight of the third tobacco component.

5. The composition of claim 1 wherein the composition comprises:
50-65% by weight of the first tobacco component,
5-10% by weight of the second tobacco component, and
35-50% by weight of the third tobacco component.

6. The composition of claim 1 wherein the composition comprises:
65-75% by weight of the first tobacco component,
5-10% by weight of the second tobacco component, and
25-35% by weight of the third tobacco component.

7. The composition of claim 1 wherein the composition comprises:
70-85% by weight of the first tobacco component,
5-25% by weight of the second tobacco component, and
5-10% by weight of the third tobacco component.
