Description
"Verfahren zur Verringerung des Nikotingehaltes von Tabak" Die ßrfindung
betrifft ein Verfahren zur Verringerung des Nikotingehaltes von Tabak. Für diesen
Zweck sind bereits zahlreiche Verfahren vorgeschlagen' worden, die aber in der überwiegenden
Mehrzahl den Nachteil be-,jitzel, daß mit der Verringerung des Nikotingehaltes auch
eine Verschlechterung der Qualität des Tabaks einhergeht oder es nicht möglich ist,
das Maß der Verringerung des Nikotingehaltes im
Alle diese Verfahren führen, soweit sie technisch überhaup-c u.-urchführbär sind, zu einer unnatürlichen und damit uneruünschten Veränderung der Tabakstruktur. .All of these procedures lead to the extent that they are technically feasible lead to an unnatural and therefore undesirable change in the tobacco structure. .
Es ist ferner bekannt, daß der Nikotingehalt-von Tabak durch die beim Fermentierungsprozeß wirksamwerdenden'nikotinabbauenden Bakterien gesenkt wird.. -Das Maß der hierdurch erzielten Verringerung des Nikotingehaltes ist aber nur gering, weil die Wirkung der nikotinabbauenden Bakterien sehr schnellt zum Stillstand kommt.-Die Erfindung schafft ein Verfahren, welches auf dieser bekannten 'Wirkung nikotinspezifischer Enzyme aufbaut und es ermöglicht, den Nikotingehalt des Tabags mit vielfach höherer Wirkung als sie durch die natürliche Wirkung der nikotinabbauenden Bakterien bei der Fermentation erreicht wird, zu verringern.It is also known that the nicotine content of tobacco by the when Fermentation process, the nicotine-degrading bacteria is lowered. -The extent of the resulting reduction in nicotine content is only small, because the action of the nicotine-degrading bacteria comes to a standstill very quickly The invention provides a method which is based on this known 'nicotine-specific effect It builds up enzymes and enables the nicotine content of the tobacco to be much higher Effect than they contribute through the natural action of nicotine-degrading bacteria the fermentation is achieved.
Das wi=rd gemäss der Erfindung dadurch erzielt, daß die Tabakblätter f-ermenter-ti,--#..cx@'erunferinentierter Tabake mit aus iäiikroorganismen isolierten nikotinabbauenden Enzymsystemen, die als solche gewonnen werden, behandelt werden. Auf diese ,eise gelingt es, ohne jede Beeinträchtigung der Qualität des Tabaks dessen Nikotingehalt erheblich und zwar auf einen vorbestimmbaren Restwert zu senken. Die für diese Behandlung zu verUendenden Enzymsysteme können nach bekannten Methoden aus nikotinabbauenden Mikroorganismen isoliert werden. Beispielsweise erfolgt dies dadurch, daß durch. Ultraschallwirkung aufgeschlossene Bakterienzellen.durch Phosphat-"uffer extrahiert tverden, viobei dann beim .Zentrifugieren der Hauptanteil der inerten Eiweißstoffe dieser Zellen im Rückstand verbleibt. Das Enzymsystem kann durch Ammoniumsulfat gefällt, d1-durch angereichert und gereinigt werden. Gegebenenfalls ist noch eine Nachreinigung desselben über eine Kolonne aus Sephadexmaterial möglich. Die Behandlung des Tabaks@.t diesen aus Mikroorganismen isolierten Enzymsystemen kann zum Beispiel erfolgen, indem auf die Tabakblätter nach einer Vorfeuchtung, die dem Zwecke dient, sie aufnälmefähig zu machen, eine wässrige Lösung der Enzyme gleichmässig in die Tabakblätter vollständig durchfeuchtender 'leise. aufgebracht wird.This is achieved according to the invention in that the tobacco leaves f-ermenter-ti, - # .. cx @ 'erunferinentierter tobacco with off microorganisms isolated nicotine-degrading enzyme systems obtained as such will. In this way, it succeeds without affecting the quality of the Tobacco has a considerable nicotine content, namely to a predeterminable residual value to lower. The enzyme systems to be used for this treatment can be prepared according to known Methods can be isolated from nicotine-degrading microorganisms. For example, takes place this by the fact that through. By ultrasound action disrupted bacterial cells Phosphate buffer is extracted, the main part then being extracted during centrifugation the inert proteins of these cells remain in the residue. The enzyme system can precipitated by ammonium sulfate, d1-by being enriched and purified. Possibly Post-purification is also possible via a column made of Sephadex material. The treatment of tobacco is based on these enzyme systems isolated from microorganisms can be done, for example, by putting on the tobacco leaves after pre-moistening, the purpose of which is to make it absorbable, an aqueous solution of the enzymes evenly in the tobacco leaves completely moisturizing 'quietly. upset will.
Gemäss einer anderen Ausführungsform des Behandlungsverfahrens -' ist es auch möglich,-Enzymanreicherungen in fester Pulverform auf vorgefeuchtete Tabakblätter aufzustäuben.According to another embodiment of the treatment method - ' It is also possible to pre-moistened enzyme enrichments in solid powder form Dusting tobacco leaves.
Das neue Verfahren kanngemäss einer weiteren Ausführungsform auch für die Behandlung von wässrigen Tabakbxtrakten, die später zur Herstellung von Kunsttabakfolzen in an sich bekannter i-lei.;e verwendet Irrerden -sollen, angewendet werden, indem diesen Extrakten das Enzymsystem zugesetzt wird.According to a further embodiment, the new method can also for the treatment of aqueous tobacco extracts that are later used in the production of Art tobacco folzen in the well-known i-lei.; E uses earthen -should, applied by adding the enzyme system to these extracts.
Die Konzentration des Enzymsystems in der verwendeten Lösung - läßt sich ohne Schwierigkeiten dem Maß der erwünschten Vermii.derung des Nikotingehaltes entsprechend einstellen.The concentration of the enzyme system in the solution used - leaves without difficulty the degree of the desired decrease in nicotine content adjust accordingly.
Der Erfolg dieser Behandlung, die die Qualität des Tabaks in -keiner Weise beeinträchtigt, ist überraschend. So konnte in dieser gleise der Nikotingehalt eines Burleytabaks von 1,2 auf o,2ö, eines Orienttabaks von 3,2 auf 2,.2" und eines Virginiatabaks von 1 9 1 auf o, ¢lo verringert werden.The success of this treatment, which in no way affects the quality of the tobacco, is surprising. Thus a Oriental tobacco from 3.2 to 2, .2 "and a Virginia tobacco from 1 to 9 1 o ¢ lo could in these tracks of the nicotine content of a Burley tobacco from 1.2 to o, 2NC be reduced.
