Tobacco cut filler has an extremely high filling capacity. Tobacco cut filler is contacted with tap water under extraction conditions, and resulting aqueous tobacco extract is separated from the water insoluble extracted tobacco material. The extracted tobacco material is contacted with humectant, provided at a desired moisture level, and subjected to volume expansion conditions. Volume expanded extracted tobacco materials are used as smokable materials in cigarette manufacture.

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.
