ABSTRACT:
This invention provides a method for reducing the protein content of tobacco material which includes extracting the tobacco material with a solution containing a surfactant. The tobacco material may be first extracted with an aqueous solvent to produce an aqueous extract before being treated with the solution containing a surfactant. This invention also provides a method for removing polypeptides from an aqueous extract of tobacco material which includes treating the extract with an insoluble adsorbent selected from the group comprising hydroxyapatite and a fuller's earth mineral such as bentonite. Treatment of the aqueous extract with bentonite will produce an extract having a reduced pigment and polypeptide content.
