Abstract

Processing of tobacco leaves for producing tobacco products, comprises: partially removing at least one of the tobacco ingredients comprising polyphenol, flavone, pigment, ethereal oil, paraffin, sterol, wax, resin or nicotine by chemical and/or physical method under the formation of a raw product; adding the pretreated raw product with at least an additive from nicotine, perfume, flavor and/or carrier material. An independent claim is included for tobacco leaves obtained by the above process.

Description

Die Erfindung betrifft ein neuartiges Verfahren zur Tabakaufbereitung für die Herstellung von Tabakwaren, bei dem in einem ersten vorgelagerten Schritt im wesentlichen alle Tabakinhaltsstoffe entfernt und dann in einem zweiten Schritt gezielt Zusatzstoffe dem Tabakrohprodukt, wie z.B. Nikotin, Koffein, Träger- und sonstige Aromastoffe, hinzugefügt werden. Die Erfindung betrifft weiterhin entsprechend hergestellte Tabakblätter sowie deren Verwendung.The invention relates to a novel process for tobacco processing for the manufacture of tobacco products, in which in a first upstream step substantially all tobacco ingredients are removed and then in a second step targeted additives to the Tabakrohprodukt such. Nicotine, caffeine, carrier and other flavorings. The invention further relates to tobacco leaves produced and their use.

Über die Gesundheitsgefährdung durch aktives und passives Rauchen besteht kein Zweifel. In einer Vielzahl von Ländern ist daher bereits das Rauchen in öffentlichen Einrichtungen verboten, um vor allem die nicht rauchende Bevölkerung zu schützen. Die den Zigaretten beigefügten Suchtstoffe erschweren erheblich den Verzicht auf Tabakkonsum.There is no doubt about the health risks of active and passive smoking. Therefore, in a large number of countries, smoking is already banned in public facilities, primarily to protect the non-smoking population. The cigarettes added to the cigarettes make it much more difficult to stop smoking.

Medikamente und Hilfsmittel wie Raucherpflaster haben nur eine eingeschränkte Wirkung. Die erheblichen Nebenwirkungen beim Rauchentzug bleiben unvermindert bestehen. Aufgrund der Nebenwirkungen dieser Medikamente erscheint ihre Einnahme risikoreicher als das Weiterrauchen.Medication and aids such as smoker patches have only a limited effect. The significant side effects of smoking withdrawal remain unabated. Because of the side effects of these drugs, taking them seems to be more risky than continuing.

Aufgabe der Erfindung ist es daher, Tabakblätter für die Herstellung von Tabakwaren bereitzustellen, die von ihren wesentlichen gesundheitsgefährdenden Stoffen ganz oder teilweise befreit sind, ohne hierbei die Wirkung der für den Genuss relevanten Inhaltsstoffe zu verändern. Weiterhin ist es Aufgabe der Erfindung, Tabakwaren herzustellen, bei denen die Suchtstoffe, wie z.B. Nikotin, schrittweise immer weiter reduzierbar sind, sodass über einen begrenzten Zeitraum, von beispielsweise 12 Monaten, ein vollständiger Rauchverzicht ohne die bekannten Entzugserscheinungen gewährleistet ist.The object of the invention is therefore to provide tobacco leaves for the manufacture of tobacco products, which are completely or partially exempted from their essential health-endangering substances, without changing the effect of relevant ingredients for the enjoyment of ingredients. It is a further object of the invention to produce tobaccos in which the addictive substances, e.g. Nicotine, are progressively reducible, so over a limited period of, for example, 12 months, a complete smoking waiver is guaranteed without the known withdrawal symptoms.

Die Erfindung wird in Bezug auf das Verfahren durch die Merkmale des Anspruchs 1 und in Bezug auf die Tabakblätter durch die Merkmale des Anspruchs 10 gelöst. Der Unteranspruch gibt vorteilhafte Weiterbildungen an.The invention is achieved with respect to the method by the features of claim 1 and with respect to the tobacco leaves by the features of claim 10. The dependent claims are advantageous developments.

Erfindungsgemäß wird somit nach Patentanspruch 1 vorgeschlagen, in einem ersten Verfahrensschritt Tabakblätter zumindest teilweise von mindestens einem Tabakinhaltsstoff zu befreien. Bei den Tabakinhaltsstoffen sind u.a. Polyphenole, Flavone, Pigmente, ätherische Öle, Paraffine, Sterine, Wachse und Harze sowie Nikotin zu nennen. Gemäß der vorliegenden Erfindung ist es nun besonders bevorzugt, wenn nicht nur einer, sondern alle der vorstehend genannten Tabakinhaltsstoffe im wesentlichen vollständig entfernt werden. Die Entfernung muss dabei gemäß der vorliegenden Erfindung so schonend erfolgen, dass nur die vorstehend genannten Tabakinhaltsstoffe entfernt werden und die restlichen Bestandteile des Tabaks wie Cellulose, Stärke, Kohlehydrate und weitere Substanzen sowie Fett und Säuren, Proteine und Pektine erhalten bleiben. Das Gerüst des Tabaks bleibt somit unverändert.According to the invention it is thus proposed according to claim 1, in a first process step to free tobacco leaves at least partially from at least one tobacco ingredient. The tobacco ingredients include polyphenols, flavones, pigments, essential oils, paraffins, sterols, waxes and resins, as well as nicotine. According to the present invention, it is now particularly preferred if not just one, but all of the aforementioned tobacco ingredients be substantially completely removed. According to the present invention, the removal must be carried out so gently that only the aforementioned tobacco ingredients are removed and the remaining constituents of the tobacco such as cellulose, starch, carbohydrates and other substances as well as fat and acids, proteins and pectins are retained. The framework of the tobacco thus remains unchanged.

Erfindungsgemäß werden als geeignete Verfahren die an und für sich im Stand der Technik bekannten technischen Extraktionsverfahren z.B. zur Entfernung des Nikotins durch Behandlung mit Ammoniak und Wasserdampf sowie auch die Destraktion mit überkritischem CO2 vorgeschlagen. Besonders bevorzugt ist es jedoch, wenn die Inhaltsstoffe unter Vakuum und Temperatur pyrolytisch abgetrennt und abdestilliert werden. Das wie vorstehend beschriebene Behandlungsverfahren führt dann zu einem Rohprodukt.According to the invention, as suitable methods, the technical extraction methods known per se in the prior art, for example for removing the nicotine by treatment with ammonia and water vapor, and also the refraction with supercritical CO 2 are proposed. However, it is particularly preferred if the ingredients are separated by distillation under vacuum and temperature and distilled off. The treatment process as described above then leads to a crude product.

Gemäß der vorliegenden Erfindung wird nun in einem zweiten Verfahrensschritt dieses Rohprodukt gezielt wiederum mit Zusatzstoffen versetzt. Das Versetzen mit den Zusatzstoffen wird dabei bevorzugt unter Druck, Temperatur und Feuchtigkeit, durch Imprägnierung, z.B. in einem Autoklaven, vorgenommen. Bei den Zusatzstoffen handelt es sich dabei im wesentlichen um Nikotin sowie Geruchs-, Geschmacks- und/oder Trägerstoffe. Als wesentlicher Vorteil ist bei dem vorliegenden Verfahren zu nennen, dass durch die gezielte Zugabe von Nikotin Tabakblätter hergestellt werden können, die dann zu Tabakwaren weiterverarbeitet werden, die einen definierten Nikotingehalt aufweisen. Der Nikotingehalt der Tabakblätter kann dabei auf Werte von 0,5 bis 5,5 Gew.-% gezielt eingestellt werden. Weiterhin vorteilhaft ist, dass nicht nur der Nikotingehalt eingestellt werden kann, sondern dass dann je nach Belieben verschiedene weitere Zusatzstoffe, wie Geruchs-, Geschmacks- und Trägerstoffe zugegeben werden können, um dem Tabak und damit den daraus hergestellten Tabakwaren entsprechende Eigenschaften zu verleihen. Bei den Geruchs- und Geschmacksstoffen sind u.a. Zuckerlösungen, Honig, Gewürze und Fruchtextrakte, Vanillin, Koffein und ändere nach der Aromenverordnung zugelassene Stoffe geeignet.According to the present invention, in a second method step, this crude product is then in turn deliberately mixed with additives. The addition of the additives is preferably carried out under pressure, temperature and humidity, by impregnation, for example in an autoclave. The additives are essentially nicotine and odor, flavor and / or carrier substances. A significant advantage of the present process is that by the deliberate addition of nicotine tobacco leaves can be produced, which are then processed into tobacco products which have a defined nicotine content. The nicotine content of the tobacco leaves can be adjusted to values of 0.5 to 5.5 wt .-% targeted. It is furthermore advantageous that not only the nicotine content can be adjusted, but that various further additives, such as odor, flavor and carrier substances can then be added as desired in order to give the tobacco and thus the tobacco products produced therefrom corresponding properties. In the case of the odoriferous and flavoring substances, sugar solutions, honey, spices and fruit extracts, vanillin, caffeine and other substances permitted by the Flavoring Ordinance are suitable.

Beim erfindungsgemäßen Verfahren ist es selbstverständlich, wie bisher schon im Stand der Technik bekannt, vorteilhaft, wenn die Tabakblätter vor der vorstehend beschriebenen Tabakaufbereitung getrocknet und fermentiert werden. Die entsprechenden Verfahren hierzu sind aus dem Stand der Technik bekannt.In the method according to the invention, it is of course, as hitherto already known in the prior art, advantageous if the tobacco leaves are dried and fermented before the tobacco preparation described above. The corresponding methods for this purpose are known from the prior art.

Es hat sich nun gezeigt, dass das vorstehend beschriebene Verfahren zur Tabakaufbereitung zu Tabakblättern und damit zu Tabakwaren führt, die dann, wenn sie zu Rauchtabak, z.B. zu Zigaretten weiterverarbeitet werden, beim Rauchen zu einem Rauchkondensat (Teer) führen, das gegenüber dem herkömmlichen Rauchwaren einen deutlich reduzierten Kondensatgehalt aufweist. Der Kondensatgehalt, der wie vorstehend beschriebenen Tabakwaren kann durch das erfindungsgemäße Verfahren auf unter 9 mg in einer Zigarette bevorzugt auf unter 5 mg, besonders bevorzugt auf unter 2 mg, reduziert werden.It has now been found that the process described above for tobacco processing leads to tobacco leaves and thus to tobacco products which, when added to smoking tobacco, e.g. be processed into cigarettes, smoking lead to a smoke condensate (tar), which compared to the conventional tobacco products has a significantly reduced condensate content. The condensate content of the tobacco products as described above can be reduced by the process according to the invention to below 9 mg in a cigarette, preferably below 5 mg, more preferably below 2 mg.

Bei der vorliegenden Erfindung ist besonders hervorzuheben, dass durch das vorstehend beschriebene Verfahren zur Tabakaufbereitung nicht nur bei den Tabakwaren ein deutlich reduzierter Kondensatgehalt (Teer) erreicht werden kann, sondern dass auch Tabakwaren hergestellt werden können, die einen abgestuften Nikotingehalt aufweisen. Durch Tabakwaren, die einen abgestuften Nikotingehalt aufweisen, können dann auch die entsprechenden Rauchwaren zur Entwöhnung von Rauchern eingesetzt werden. Dazu kann über einen längeren Zeitraum (bis zu ca. 12 Monaten) der Raucher Tabakwaren ausgehend von Tabakwaren mit normalem Nikotingehalt stufenweise bis zu Tabakwaren ohne Nikotin konsumieren, so dass dadurch eine Entwöhnung ohne die bekannten Entzugserscheinungen erreicht wird.In the present invention, it should be emphasized that the tobacco processing described above not only significantly reduces the condensate content (tar) in the case of tobacco products. can be achieved, but that also tobacco products can be produced, which have a graded nicotine content. By tobacco products, which have a graded nicotine content, then the corresponding tobacco products can be used to weaning smokers. For this purpose, over a longer period (up to about 12 months) the smoker can consume tobacco products starting from tobacco products with normal nicotine content gradually up to tobacco products without nicotine, thereby weaning without the known withdrawal symptoms is achieved.

Dadurch, dass beim erfindungsgemäßen Verfahren aber nicht nur abgestufte Nikotingehalte erreicht werden können, sondern zusätzlich noch Geruchs-, Geschmacks und Trägerstoffe zugesetzt werden, die spezifisch auswählbar sind, kann für den Raucher auch diese Entwöhnung gleichzeitig mit einem hohen Genuss verbunden werden.Due to the fact that not only graded nicotine contents can be achieved in the process according to the invention, but also odorants, flavors and excipients which can be selected specifically, the weaning can be combined with a high level of enjoyment for the smoker as well.

Die Erfindung betrifft weiterhin noch die mit dem vorstehend beschriebenen Verfahren hergestellten Tabakblätter bzw. die daraus herstellbaren Tabakwaren.The invention further relates to the tobacco leaves produced by the method described above or the tobacco products that can be produced therefrom.

Die erfindungsgemäßen Tabakblätter können zur Herstellung von Tabakwaren, wie Zigaretten, Zigarren und Pfeifentabak, eingesetzt werden.The tobacco leaves according to the invention can be used for the production of tobacco products, such as cigarettes, cigars and pipe tobacco.
