Claims

Providing a mixture of water and tobacco material in the form of a slurry;
Heating the mixture at a temperature and for a time sufficient to pasteurize the mixture;
Adding a sufficient amount of base to the slurry to raise the pH of the slurry to an alkaline pH, thereby forming a pH adjusted mixture;
Following the adding step, continuing to heat the pH adjustment mixture at a temperature and for a time sufficient to reduce the pH of the pH adjustment mixture by at least about 0.5 pH units, thereby forming a treated tobacco material. ,
For use as a smokeless tobacco composition comprising the steps of: drying the slurry to a moisture content of about 15 wt% or less based on the total weight of the dry tobacco material; and incorporating the treated tobacco material within the smokeless tobacco product. A method for preparing a suitable tobacco composition.

The method of claim 1, further comprising adding one or more flavorings and additional moisture to the dried tobacco material in an amount sufficient to increase the moisture content of the tobacco material to at least about 25% by weight.

The method of claim 2, further comprising cooling the pH adjustment mixture to ambient temperature, the pH adjustment mixture further having a pH of at least about 8 at the start of the cooling step.

  Providing a slurry comprising water and tobacco material, the slurry comprising at least about 75% water by weight relative to the total weight of the slurry;
  Heating the slurry to a temperature of at least about 60 ° C. for a time sufficient to pasteurize the tobacco material;
  Adding a sufficient amount of base to the slurry to raise the pH of the slurry to at least about 8.5, thereby forming a pH adjusted slurry; and
  4. The heating of the pH adjusted slurry of claim 1 to 3 subsequent to the adding step, comprising heating the pH adjusted slurry to a temperature of at least about 60 ° C. for a time sufficient to reduce the pH of the slurry to at least about 0.5 pH units. The method according to any one of the above.

The method of claim 4, further comprising adding salt to the slurry prior to the heating step.

6. The method of claim 5, wherein the step of adding salt comprises adding about 1 to about 5% by weight sodium chloride relative to the dry weight of the tobacco material.

4. The method of claim 3, further comprising adding a humectant during or after the cooling step.

4. The method of any one of claims 1-3, wherein the adding step comprises adding sufficient base to raise the pH of the slurry to at least about 9.

  Providing a mixture of water, tobacco material and salt in the form of a slurry;
  Heating the mixture at a temperature and for a time sufficient to pasteurize the tobacco material;
  Adding a sufficient amount of base to the slurry to raise the pH of the slurry to at least about 8.5, thereby forming a pH adjusted slurry; and
  Following the adding step, continuing to heat the pH adjustment mixture at a temperature and for a time sufficient to reduce the pH of the pH adjustment mixture by at least about 0.5 pH units, thereby forming a treated tobacco material.
  The method according to claim 1, comprising:

  Providing a slurry comprising water and tobacco material, the slurry comprising at least about 80% water by weight relative to the total weight of the slurry;
  Heating the slurry to a temperature of at least about 70 ° C. for a time sufficient to pasteurize the tobacco material;
  Adding a sufficient amount of base to the slurry to raise the pH of the slurry to at least about 9, thereby forming a pH adjusted slurry;
  Following the adding step, continuing heating the pH adjusted slurry to a temperature of at least about 60 ° C. for a time sufficient to reduce the pH of the slurry by at least about 0.5 pH units; and
  Cooling the pH adjusted slurry to ambient temperature, the pH adjusted slurry having a pH of at least about 8 at the start of the cooling step.
  The method according to claim 1, comprising:

  Providing a slurry comprising water and tobacco material, the slurry comprising at least about 80% water by weight relative to the total weight of the slurry;
  Heating the slurry to a temperature of at least about 70 ° C. for at least about 30 minutes;
  Adding a sufficient amount of base to the slurry to raise the pH of the slurry to at least about 9.5, thereby forming a pH adjusted slurry;
  Continuing to heat the pH adjusted slurry to a temperature of at least about 60 ° C. for at least about 1.5 hours;
  Cooling the pH adjusted slurry to ambient temperature, the pH adjusted slurry having a pH of at least about 8 at the start of the cooling step;
  Adding a humectant to the pH adjusting slurry during or after the cooling step; and
