REMOVAL OF NITROGEN CONTAINING COMPOUNDS FROM TOBACCO

摘要

The present invention provides for a process for removing nitrogen containing compounds from tobacco with minimum removal of desired compounds. The process includes the steps of mixing a tobacco containing material with an aqueous solvent to form an extract; the extract is then separated from the tobacco containing material and contacted with an adsorbent material. The adsorbent material is selected from the group consisting of a mixture of bentonite and activated carbon material, .beta.-cyclodextrin, cellulose acetate and combinations thereof. The extract is then added back to a tobacco containing material that may or may not have been processed.
