Wax encapsulated zeolite flavour delivery system for tobacco
A flavour delivery system for tobacco includes a flavour material entrained in a zeolite material and forming a core and a wax material encapsulating the core.
1. A flavour delivery system for tobacco comprising:
a flavour material entrained in a zeolite material and forming a core comprising the flavour material and the zeolite,
a wax material applied onto the core in molten form and surrounding the core and forming an encapsulated flavour particle,
the core comprising from 1% to 50% of a total weight of the encapsulated flavour particle,
wherein the encapsulated flavour particle has a particle size in a range from about 5 micrometres to about 80 micrometres, and the zeolite material has a particle size in a range from about 1 micrometer to about 20 micrometers.
2. A flavour delivery system according to claim 1 , wherein the wax material has a melting point of about 100 degrees centigrade or greater.
3. A flavour delivery system according to claim 2 , wherein the zeolite material is hydrophobic.
4. A flavour delivery system according to claim 1 , wherein the zeolite material is hydrophobic.
5. A flavour delivery system according to claim 1 , wherein the flavour material is a hydrophobic liquid.
6. A smoking composition comprising tobacco material and the flavour delivery system according to claim 1 .
7. A smoking composition according to claim 6 , wherein the tobacco material comprises homogenized tobacco.
8. A smoking composition according to claim 6 , wherein the tobacco material comprises cast leaf tobacco.
9. A smoking composition according to claim 6 , wherein at least a portion of the wax material is melted off the core and is dispersed within the tobacco material.
10. A smoking article comprising an aerosol forming substrate comprising the smoking composition of claim 6 .
11. A smoking article comprising an aerosol forming substrate comprising the smoking composition of claim 9 .
12. A method of forming a smoking composition comprising:
combining tobacco material with the flavour delivery system according to claim 1 to form a tobacco mixture; and
heating the tobacco mixture to form the smoking composition.
13. A method of forming a smoking composition according to claim 12 , wherein the tobacco material comprises homogenized tobacco and water and the heating step removes at least a portion of the water from the tobacco mixture to form the smoking composition.
14. A method of forming a smoking composition according to claim 13 , wherein the heating step melts at least a portion of the wax material.
15. A method of forming a smoking composition according to claim 12 , wherein the heating step melts at least a portion of the wax material.
16. A method of forming a smoking composition according to claim 12 , wherein the heating step does not melt the wax material.
