Abstract

The invention relates to a method for treating tobacco material, the method comprising: o fermenting the tobacco material to obtain treated tobacco material, including: #incubating the tobacco material under anaerobic conditions; #applying a pressure to the tobacco material comprised between 1000 kilograms per square meter and 4000 kilograms per square meter; #keeping the moisture content of the tobacco material comprised between 25 percent in weight and 40 percent in weight of the total weight of the tobacco material; o wherein the fermenting lasts at least one month.

Claims (18)

1 . A method for treating tobacco material, the method comprising:

fermenting the tobacco material to obtain treated tobacco material, including:

incubating the tobacco material under anaerobic conditions;

applying a pressure to the tobacco material comprised between 1000 kilograms per square meter and 4000 kilograms per square meter;

keeping the moisture content of the tobacco material comprised between 25 percent in weight and 40 percent in weight of the total weight of the tobacco material;

wherein the fermenting lasts at least two months.

2 . The method according to claim 1 , including the step of:

drying the tobacco material to obtain a dried tobacco material having a moisture content comprised between 5 percent and 10 percent in weight of the total weight of the tobacco material.

3 . The method according to claim 1 , comprising the step of:

curing the tobacco material before fermenting.

4 . The method according to claim 1 , including keeping the temperature of the tobacco material comprised between 25 degrees Celsius and 35 degrees Celsius.

5 . The method according to claim 1 , comprising the step of turning the tobacco material.

6 . The method according to claim 1 , comprising:

securing the tobacco material within a moisture retaining material.

7 . The method according to claim 1 , comprising:

wetting the tobacco material in water before fermenting, so that a moisture content of the tobacco material comprised between 25 percent in weight and 40 percent in weight of the total weight of the tobacco material is achieved.

8 . The method according to claim 1 , wherein the amount of asparagine in the treated tobacco material becomes at least 50 percent lower than the amount of asparagine contained in the same tobacco material before treatment.

9 . The method according to claim 1 , wherein the amount of reducing sugars in the treated tobacco material becomes at least 50 percent lower than the amount of reducing sugars contained in the same tobacco material before treatment.
