Abstract

A tobacco material having at least about 40% water based on the total weight, and having a storage stability of at least about 25 days is provided herein, wherein the storage stability is defined as an aerobic plate count below about 3,000,000 CFU/g. A method of treating a tobacco material to enhance storage stability is also provided herein, the method including receiving a tobacco material having at least about 40% water based on the total weight and subjecting the tobacco material to a process pressure of at least about 30,000 psi to form a high pressure processed tobacco material, wherein the high pressure processed tobacco material has a storage stability of at least about 25 days, and wherein the storage stability is defined as an aerobic plate count below about 3,000,000 CFU/g.

First claim

What is claimed is:

1 . A tobacco material having at least about 40% water based on the total weight, and having a storage stability of at least about 25 days, wherein the storage stability is defined as an aerobic plate count below about 3,000,000 CFU/g.

2 . The tobacco material of claim 1 , wherein the tobacco material is stored at about 37° C.

3 . The tobacco material of claim 1 , wherein the tobacco material is stored at about 4° C.

4 . The tobacco material of claim 3 , wherein the storage stability is at least about 75 days.

5 . The tobacco material of claim 4 , wherein the storage stability is at least about 100 days.

6 . The tobacco material of claim 1 , wherein the tobacco material is in the form of a particulate material.

7 . The tobacco material of claim 1 , wherein the tobacco material is in the form of an aqueous extract.

8 . A tobacco product incorporating the tobacco material of claim 1 .

9 . The tobacco product of claim 8 , wherein the tobacco product is a smoking article.

10 . The tobacco product of claim 8 , wherein the tobacco product is a smokeless tobacco product.

11 . A method of treating a tobacco material to enhance storage stability, comprising:
receiving a tobacco material having at least about 40% water based on the total weight; subjecting the tobacco material to a process pressure of at least about 30,000 psi to form a high pressure processed tobacco material; wherein the high pressure processed tobacco material has a storage stability of at least about 25 days, wherein the storage stability is defined as an aerobic plate count below about 3,000,000 CFU/g.

12 . The method of claim 11 , wherein the high pressure processed tobacco material is stored at about 37° C.

13 . The method of claim 11 , wherein the high pressure processed tobacco material is stored at about 4° C.

14 . The method of claim 13 , wherein the storage stability is at least about 75 days.

15 . The method of claim 14 , wherein the storage stability is at least about 100 days.

16 . The method of claim 11 , wherein the tobacco material is in the form of a particulate material.

17 . The method of claim 11 , wherein the tobacco material is in the form of an aqueous tobacco extract.

18 . The method of claim 11 , wherein the process pressure is at least about 75,000 psi.

19 . The method of claim 11 , wherein the tobacco material is subjected to the process pressure for a holding time of at least about 30 seconds.

20 . The method of claim 19 , wherein the holding time is in the range of about 180 seconds to about 300 seconds.

21 . The method of claim 11 , further comprising incorporating the high pressure processed tobacco material into a tobacco product.

22 . The method of claim 21 , wherein the tobacco product is a smoking article.

23 . The method of claim 21 , wherein the tobacco product is a smokeless tobacco product.
