Abstract:
1. A method of preparing an aqueous tobacco slurry or aqueous tobacco extract having increased storage stability, comprising: providing a tobacco material; contacting the tobacco material with an aqueous solution to form the aqueous tobacco slurry such that water-soluble components of the tobacco material are extracted from the tobacco material into the aqueous solution; optionally, separating at least a portion of the aqueous solution from the tobacco material to form the aqueous tobacco extract; adding a tocopherol or derivative thereof to the aqueous tobacco slurry or the aqueous tobacco extract such that the storage stability of the aqueous tobacco slurry or the aqueous tobacco extract is increased; storing the aqueous tobacco slurry or the aqueous tobacco extract for a period of time of at least 5 days following said adding step; forming a reconstituted tobacco material comprising the stored aqueous tobacco slurry or the stored aqueous tobacco extract; and incorporating the reconstituted tobacco material into a tobacco blend.
