Abstract
A process is disclosed for removing proteins and other undesirable biomolecules from tobacco extract or slurry via foam fractionation, thereby concentrating the tobacco extract or slurry. The tobacco extract or slurry is treated and modified prior to being subjected to the foam fractionation to enhance the extent and efficiency of protein removal. After foam fractionation, the concentrated extract, sans proteins and other Hoffman analyte precursors, is applied to a tobacco sheet material, and the collected foam can be recirculated through foam fractionation for enhanced concentration.
