Abstract
Flavorful tobacco substances are provided by extracting tobacco with water, spray drying the resulting liquid tobacco extract, contacting the spray dried extract with a glycerine carrier, and subjecting the extract and carrier to a temperature above 150.degree. C. for a period of time sufficient to eliminate the harsh or "green" taste provided by the extract. The flavorful tobacco substances are useful as forms of tobacco in smoking product manufacture.
