ABSTRACT:
Denicotinized tobacco cut filler is provided by (i) extracting the cut filler with an aqueous denicotinized extract and thereby providing a mixture of aqueous extract and extracted cut filler, (ii) deliquoring the mixture of aqueous extract and extracted cut filler such that a certain level of tobacco extract remains in contact with the extracted cut filler, and (iii) drying the deliquored tobacco extract/extracted cut filler to provide a processed cut filler. Greater than 90 percent of the nicotine present in tobacco cut filler can be removed therefrom using such process steps.
