Title (EN) REMOVAL OF NITROGEN CONTAINING COMPOUNDS FROM TOBACCO
(FR) ELIMINATION DE COMPOSES AZOTES DU TABAC
Abstract: front page image
(EN)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 bentonite and activated carbon material, &bgr;-cyclodextrin, cellulose acetate and combinations thereof. The extract is then added back to the tobacco containing material that may or may not have been processed.
(FR)La présente invention concerne une méthode d'élimination de composés azotés du tabac, avec élimination minimale de composés désirés. La méthode de l'invention consiste à mélanger un matériau à base de tabac avec un solvant aqueux pour former un extrait. L'extrait est ensuite séparé du matériau à base de tabac et placé au contact d'un matériau adsorbant. Le matériau adsorbant est sélectionné dans le groupe constitué par une bentonite et un matériau charbonneux, ?-cyclodextrine, un acétate de cellulose et leurs combinaisons. L'extrait est ensuite rajouté au matériau à base de tabac qui peut avoir été traité ou non.
