Abstract

L'invention concerne un procédé de traitement du tabac destiné à réduire ou à éliminer les nitrosamines qu'il contient. Le procédé consiste à utiliser un milieu d'extraction de fluide supercritique à pression et température élevées afin d'extraire sélectivement les nitrosamines par rapport à l'extraction de nicotine. Il est possible de réduire la teneur en nitrosamines de tous les types de tabac.
