Description

Verfahren zur Herstellung nikotinfreien Tabaks Es wurde gefunden, daß flüssiges Schwefeldioxyd sehr gut als Extraktionsmittel zur Darstellung nikotinfreien Tabaks geeignet ist.Process for the production of nicotine-free tobacco It was found that liquid sulfur dioxide works very well as an extractant for making nicotine-free Tobacco is suitable.

Es ist zwar schon bekannt, daß sich Nikotin in flüssigem Schwefeldioxyd löst; aber daraus war weder zu entnehmen, daß flüssiges Schwefeldioxyd auch geeignet ist, Nikotin aus der Droge herauszuholen, noch daß der mit flüssigem Schwefeldioxyd behandelte Tabak noch ein wertvolles Genußmittel darstellt. Flüssiges Schwefeldioxyd besitzt ein sehr hohes Lösungsvermögen für Nikotin, wie es in der Droge vorliegt, so daß die Entziehung des Nikotins aus dem Tabak sehr schnell und sehr weitgehend erfolgt. Die besondere Eigenart des flüssigen Schwefeldioxyds, in diesem Falle zugleich als Säureanhydrid und als Lösungsmittel zu wirken, macht es überflüssig, weitere Zusätze alkalischer oder saurer Natur zu machen, um das Nikotin aus seiner in der Pflanze bestehenden Bindung in Freiheit zu setzen. Der niedrige Siedepunkt dieses Lösungsmittels gestattet, für den Extraktionsprozeß höhere Temperaturen zu vermeiden, so daß infolgedessen die das Aroma des Tabaks bedingenden Bestandteile weitgehend geschont werden. Außerdem aber läßt sich das Lösungsmittel nach erfolgter Extraktion sehr- leicht und ohne Anwendung höherer Temperaturen aus dein Extraktionsgut wieder entfernen. Die äußere Struktur des Tabaks bleibt unverändert. Das Schwefeldioxyd entzieht dem Tabak außer dem Nikotin nur geringe Mengen anderer Extraktivstoffe. Diese lassen sich dem Tabak nach ..erfolgter Extraktion in an sich bekannter Weise wieder unverändert zusetzen, nachdem das Nikotin dem Extraktrückstand durch Wasser entzogen worden ist. Abgesehen von dem Entzug des Nikotins behält also der Tabak seine übrigen charakteristischen Eigenschaften. Beispiel: i kg Tabak wird er Extraktion mit flüssgetn Schwefeldioxyd bei einer Temperatur, die 4o° nicht übersteigen soll, unterworfen Nach dreimaliger Erneuerung des Lösungsmittels sind etwa go °% des Nikotins extrahiert. Dem Extrakt wird das Nikotin direkt mit Wasser entzogen und der nikotinfreie Anfall dem Tabak in geeigneter Weise wieder zugesetzt.It is already known that nicotine is in liquid sulfur dioxide solves; but from this it could not be inferred that liquid sulfur dioxide was also suitable is to get nicotine out of the drug, nor that with liquid sulfur dioxide treated tobacco is still a valuable stimulant. Liquid sulfur dioxide has a very high dissolving power for nicotine, as it is in the drug, so that the withdrawal of nicotine from tobacco is very rapid and very extensive he follows. The special peculiarity of liquid sulfur dioxide, in this case at the same time Acting as an acid anhydride and as a solvent eliminates the need for further Additives of an alkaline or acidic nature to make the nicotine out of its in the Plant existing bond in freedom. The low boiling point of this Solvent allows to avoid higher temperatures for the extraction process, so that as a result the components which determine the aroma of the tobacco largely be spared. In addition, however, the solvent can be used after extraction very easily and without the use of higher temperatures from your extraction material remove. The external structure of the tobacco remains unchanged. The sulfur dioxide Apart from nicotine, it removes only small amounts of other extractive substances from tobacco. After extraction has taken place, these can be added to the tobacco in a manner known per se Add again unchanged after the nicotine is added to the extract residue through water has been withdrawn. So apart from the withdrawal of nicotine, the tobacco keeps its other characteristic properties. Example: i kg of tobacco he is extraction with liquid sulfur dioxide at a temperature that should not exceed 40 °, after three renewals of the solvent are about go °% of the nicotine extracted. The nicotine is removed from the extract directly with water and the nicotine-free one Attack added back to the tobacco in a suitable manner.
