Abstract (en)

[origin: EP1782702A1] A method of manufacturing a regenerated tobacco material includes extracting a natural tobacco material with an aqueous extracting solvent to obtain an extract solution containing components of the natural tobacco material and an extraction residue, subjecting the extract solution to an adsorption separation operation using an adsorbent to reduce an amount of nitrosamines, preparing a regenerated tobacco web using the extraction residue, and adding at least a part of the extract solution in which the amount of nitrosamines is reduced, to the regenerated tobacco web. The adsorbent is a strongly hydrophobic adsorbent. The adsorption separation operation is carried out within 60 minutes using the strongly hydrophobic adsorbent in an amount corresponding to 10 to 110% of a weight of soluble components of the extract solution.
