Abstract (en)
[origin: US4506682A] The invention relates to a process for obtaining aromatic materials from a tobacco extract (primary extract) obtainable by means of solvents, by mixing this tobacco extract with an adsorbent, treating the mixture obtained with CO2 in a pressure extraction vessel under extraction conditions (secondary extraction) and isolating a clear tobacco aroma oil in a downstream separating vessel. The invention also relates to a new tobacco aroma oil which is free of resins, waxes and polyphenols and has a considerably reduced nicotine content. The invention further relates to the use of the obtainable tobacco aroma oil for aromatizing tobacco or tobacco products.
