Abstract
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.
