Abstract: The invention relates to a method for the preparation of a homogenized tobacco material, said method comprising: —pulping and refining cellulose fibres to obtain fibres having a mean size per weight comprised between about 0.2 millimetres and about 4 millimetres; —grinding a blend of tobacco of one or more tobacco types to tobacco particles having a mean size per weight comprised between about 0.03 millimetres and about 0.12 millimetres; —Combining the cellulose fibres with the tobacco particles and with a binder to form a slurry; —homogenizing the slurry; —adding asparaginase to the slurry; and—forming the homogenized tobacco material from the slurry, wherein the homogenized tobacco material comprises from about 1 percent and about 5 percent in dry weight basis of the binder.
