Abstract
Tobacco material having a reduced protein content is provided by first extracting water soluble components from tobacco. The extracted residue then is subjected to enzyme treatment using an enzyme which can decompose water insoluble protein molecules to smaller sized water soluble molecular components. The enzyme treated extracted tobacco material then is isolated. The extracted tobacco components then can be reapplied to the protein reduced tobacco material. The tobacco material so processed is use as smokable material for cigarette manufacture.
