- Appl. No: 14/847485
- Application Filed: September 08, 2015
- Assignees: R.J. Reynolds Tobacco Company (Winston-Salem, NC, US)
- Claim: 1. 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; adjusting the pH of the tobacco material to be in the range of about 4 to about 6; sealing the tobacco material in a package and introducing the sealed tobacco material to a pressurizing medium; subjecting the sealed tobacco material to a process pressure of at least about 30,000 psi by way of isostatic pressure transmitted by the pressurizing medium to form a high pressure processed tobacco material; wherein the high pressure processed tobacco material has a first storage stability of at least about 25 days at a storage temperature of about 37° C., wherein the first storage stability is defined as an aerobic plate count below about 3,000,000 CFU/g.
- Claim: 2. The method of claim 1 , wherein the processed tobacco material has a second storage stability of at least about 75 days at a storage temperature of about 4° C., wherein the second storage stability is defined as an aerobic plate count below about 3,000,000 CFU/g.
- Claim: 3. The method of claim 2 , wherein the second storage stability is at least about 100 days.
- Claim: 4. The method of claim 1 , wherein the tobacco material is in the form of a particulate material.
- Claim: 5. The method of claim 1 , wherein the tobacco material is in the form of an aqueous tobacco extract.
- Claim: 6. The method of claim 1 , wherein the process pressure is at least about 75,000 psi.
- Claim: 7. The method of claim 1 , wherein the tobacco material is subjected to the process pressure for a holding time of at least about 30 seconds.
- Claim: 8. The method of claim 7 , wherein the holding time is in the range of about 180 seconds to about 300 seconds.
- Claim: 9. The method of claim 1 , further comprising incorporating the high pressure processed tobacco material into a tobacco product.
- Claim: 10. The method of claim 9 , wherein the tobacco product is a smoking article.
- Claim: 11. The method of claim 9 , wherein the tobacco product is a smokeless tobacco product.
