Abstract (en)
[origin: US6866045B1] The methods concerns a method for general use and more particularly used for tobacco products. The method uses in particular nitrogen-containing heterocycles such as DNA and RNA bases and complementarily polymer fibers. Said molecules and said fibers can partly halogenated, or in halogenated salt media. The halogen is preferably fluorine. Fluorine may be added to may bei n the form of a medium of fluorinated salts such as NaF, KF, Na2PO3F. The filtering acts against the formation of human intracellular DNA or RNA adducts, while preserving the nicotine and the tobacco aromas.
