Abstract

A smokeable material for inclusion in a smoking article, comprising tobacco coated with acacia gum, wherein the amount of acacia gum is at least 10% by weight of the tobacco.

First claim

The invention claimed is:

1. Smokeable material for inclusion in a smoking article, comprising tobacco coated with acacia gum, wherein the amount of acacia gum is at least 10% by weight of the tobacco, wherein the tobacco coated with acacia gum comprises at least 50% of one or more of lamina, stem and expanded tobaccos, and the acacia gum covers substantially all of a surface of at least one of the lamina, stem, and expanded tobaccos; and wherein the smokeable material comprises less than 10% tobacco dust.

2. Smokeable material as claimed in claim 1 , wherein the amount of acacia gum is at least 20% by weight of the tobacco.

3. Smokeable material as claimed in claim 2 , comprising less than 25% reconstituted tobacco; and/or less than 10% tobacco dust.

4. A method of obtaining smokeable material according to claim 2 , comprising applying a solution of acacia gum to the smokeable material and subsequently drying the smokeable material; wherein the smokeable material comprises tobacco, and wherein the solution comprises acacia gum in an amount of at least 10% by weight.

5. Smokeable material as claimed in claim 1 , further comprising one or more of tobacco substitutes, filler materials or uncoated tobacco.

6. Smokeable material as claimed in claim 5 , wherein one or more of the tobacco substitutes and filler materials are coated with acacia gum, wherein the weight of acacia gum is at least 10% by weight of the material to be coated.

7. Smokeable material as claimed in claim 1 , wherein the coating consists of acacia gum.

8. A method of obtaining smokeable material according to claim 7 , comprising applying a solution of acacia gum to the smokeable material and subsequently drying the smokeable material; wherein the smokeable material comprises tobacco, and wherein the solution comprises acacia gum in an amount of at least 10% by weight.

9. Smokeable material as claimed in claim 1 , wherein the coating further comprises one or more of diluents, humectants, flavours or flavourants, and aerosol generating means.

10. Smokeable material as claimed in claim 1 , comprising less than 25% reconstituted tobacco.

11. Smokeable material as claimed in claim 1 , wherein the tobacco coated with acacia gum comprises less than 20% reconstituted tobacco and/or less than 10% tobacco dust.

12. A method of obtaining smokeable material according to claim 11 , comprising applying a solution of acacia gum to the smokeable material and subsequently drying the smokeable material; wherein the smokeable material comprises tobacco, and wherein the solution comprises acacia gum in an amount of at least 10% by weight.

13. A method of obtaining smokeable material according to claim 1 , comprising applying a solution of acacia gum to the smokeable material and subsequently drying the smokeable material; wherein the smokeable material comprises tobacco, and wherein the solution comprises acacia gum in an amount of at least 10% by weight.

14. A method according to claim 13 , wherein the solution comprises acacia gum in an amount of at least 20% by weight.

15. A method according to claim 13 , wherein the solution further comprises one or more of diluents, humectants, flavours or flavourants, and aerosol generating means.

16. A method according to claim 13 , wherein the smokeable material to which the solution of acacia gum is applied comprises less than 25% reconstituted tobacco; and/or less than 10% tobacco dust.

17. Method according to claim 13 , wherein the solution of acacia gum is configured to reduce the level of one or more constituents of mainstream smoke generated upon use of a smoking article.

18. A smoking article comprising smokeable material according to claim 1 .

19. A smoking article as claimed in claim 18 , wherein the tobacco in the smoking article coated with acacia gum comprises at least 50% of one or more of lamina, stem and expanded tobaccos.

20. Smokeable material as claimed in claim 1 , wherein the coating consists of acacia gum.

21. Smokeable material as claimed in claim 1 , comprising substantially no tobacco dust.
