Description
Die Erfindung betrifft ein Verfahren zur Aromatisierung von aus einer Zigarette abgesogenem Tabakrauch mittels einem im Mundstück der Zigarette angeordneten, mit Aromastoffen beladenen Silikagel, ein Zigarettenendstück, insbesondere Zigarettenfilter, zur Durchführung des Verfahrens, sowie eine Verwendung dieses Verfahrens.The invention relates to a method for aromatizing tobacco smoke extracted from a cigarette by means of a silica gel arranged in the mouthpiece of the cigarette and loaded with flavorings, a cigarette end piece, in particular cigarette filter, for carrying out the method, and a use of this method.
Es ist aus FR-A-1 589 807 bereits bekannt, Silikagel als Aromastoffträger zu verwenden. Silikagel als Aromastoffträger weist jedoch den Nachteil auf, dass für eine wirklich gute Aromatisierung von aus einer Zigarette abgesogenem Tabakrauch einerseits wegen dem hohen Adsorptionsvermögen des Silikagels sehr viel vom meist sehr teuren Aromastoff benötigt wird, anderseits bei den dazu erforderlichen hohen Aromabeladungen die Lagerfähigkeit unbefriedigend, und als in der Praxis äussert wichtiger Punkt, die Aromaabgabe an den am mit dem Aromastoff beladenen Silikagel vorbeiströmenden warmen und feuchten - Rauchgasstrom über die Abrauchdauer der Zigarette gesehen, zu ungleichmässig ist.It is already known from FR-A-1 589 807 to use silica gel as a flavoring agent. However, silica gel as a flavoring substance carrier has the disadvantage that for a really good flavoring of tobacco smoke extracted from a cigarette, on the one hand a great deal of the mostly very expensive flavoring material is required because of the high adsorption capacity of the silica gel, and on the other hand the storage capacity is unsatisfactory given the high aroma loads required for this As an important point in practice, the aroma delivery to the warm and humid flue gas stream flowing past the silica gel loaded with the aroma substance is too uneven over the smoking time of the cigarette.
Aufgabe der vorliegenden Erfindung ist die Schaffung eines Verfahrens zur Aromatisierung von aus einer Zigarette abgesogenem Tabakrauch, bei dessen Anwendung einerseits während der Lagerung der Zigaretten resp. des erfindungsgemäss beladenen Silikagels praktisch kein Aromastoff unerwünschterweise an die Umgebung abgegeben wird, so dass nur eine minimale Menge vom meist sehr teuren Aromastoff erforderlich ist, und anderseits während dem Abrauchen einer derart aromatisierten Zigarette dieser Aromastoff über die gesamte Abrauchdauer sehr gleichmässig und praktisch vollständig an den vorbeiströmenden feuchteissen Rauchgasstrom abgegeben wird.The object of the present invention is to provide a method for aromatizing tobacco smoke sucked from a cigarette, when used on the one hand during storage of the cigarettes or. of the silica gel loaded according to the invention, practically no aroma substance is undesirably released into the environment, so that only a minimal amount of the usually very expensive aroma substance is required, and on the other hand, during the smoking of such a flavored cigarette, this aroma substance is very evenly and practically completely passed on to the entire period of smoking flowing wet and flue gas flow is released.
Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art erfindungsgemäss dadurch gelöst, dass man die Adsorptionsfähigkeit des hochporösen Silikagels mit Hilfe von als Desaktivierungsmittel wirkendem Propylenglykol auf einen gewünschten Wert einstellt.This object is achieved according to the invention in a method of the type mentioned at the outset by adjusting the adsorbability of the highly porous silica gel to a desired value with the aid of propylene glycol which acts as a deactivating agent.
Es hat gezeigt, dass granulatförmiges, poröses Silikagel, dessen Adsorptionsfähigkeit mit Hilfe von als Desaktivierungsmittel wirkendem Propylenglykol auf einem bestimmten Wert eingestellt ist, ein ausgezeichnetes Adsorptionsvermögen zur Speicherung von Aromastoffen aufweist, und selbst bei offener Lagerung des derart mit Aromastoffen beladenen Aromaträgers bei Raumtemperatur (ca. 18 bis 22°C) über eine Zeitdauer von mehreren Monaten die Verflüchtigung des gespeicherten Aromastoffes so gering ist, dass noch eine genügende Menge an letzterem im Aromaträger espeichert vorhanden ist. Befindet sich anderseits der derart mit Aromastoffen beladene Aromaträger in einem warmen und feuchten Rauchgasstrom einer Zigarette, dann wird bei jedem Zug des Rauchers an einer solchen Zigarette, wie erwünscht, eine bestimmte relativ gleichmässige Menge an Aromastoff an den vorbeiströmenden warmen und feuchten Rauchgasstrom abgegeben.It has been shown that granular, porous silica gel, the adsorption capacity of which is set to a certain value with the aid of propylene glycol acting as a deactivating agent, has an excellent adsorption capacity for storing aroma substances, and even when the aroma carrier thus loaded with aroma substances is stored at room temperature (approx 18 to 22 ° C) over a period of several months the volatilization of the stored aroma substance is so low that there is still a sufficient amount of the latter stored in the aroma carrier. On the other hand, if the aroma carrier thus loaded with aroma substances is in a warm and moist flue gas stream of a cigarette, then with each pull of the smoker on such a cigarette, as desired, a certain relatively uniform amount of aroma substance is released to the flowing warm and humid flue gas stream.
Es ist vorteilhaft, wenn man als Aromastoff ein synthetisches Tabakaroma, einen natürlichen oder synthetischen Tabakextrakt, einen natürlichen oder synthetischen Tabakrauchextrakt oder ein Phenoläther, zum Beispiel Anethol oder Anisol, verwendet.It is advantageous if a synthetic tobacco aroma, a natural or synthetic tobacco extract, a natural or synthetic tobacco smoke extract or a phenol ether, for example anethole or anisole, is used as the aroma substance.
Es hat sich als zweckmässig erwiesen, wenn man ein Silikagel mit einer spezifischen Oberfläche im Bereich von 300 bis 700m2g, vorzugsweise von etwa 550m2/g verwendet. Dabei ist es ferner vorteilhaft, wenn man ein Silikagel mit einem Porenvolumen im Bereich von 0,6 bis 0,85 ml/g, vorzugsweise von etwa 0,73 ml/g, verwendet.It has proven expedient if a silica gel with a specific surface area in the range from 300 to 700 m 2 g, preferably of about 550 m 2 / g, is used. It is also advantageous if a silica gel with a pore volume in the range of 0.6 to 0.85 ml / g, preferably of about 0.73 ml / g, is used.
Es hat sich zur Erzielung einer guten Aromatisierung des Zigarettenrauches ausserdem als zweckmässig erwiesen, wenn man ein mit 16 bis 44 Gew.-%, vorzugsweise mit etwa 30 Gew.-%. bezogen auf das unbeladene Silikagel, mit Aromastoffen und Desaktivierungsmittel beladenes Silikagel verwendet.In order to achieve good flavoring of the cigarette smoke, it has also proven to be expedient if one contains 16 to 44% by weight, preferably about 30% by weight. based on the unloaded silica gel, silica gel loaded with flavorings and deactivating agent.
Es ist ferner vorteilhaft, wenn man ein Silikagel verwendet, welches bei einem Aequilibrium von 20°C und 50% relativer Luftfeuchtigkeit bezogen auf die Trockensubstanz des Silikagel, 5 bis 18 Gew.-%, vorzugsweise etwa 8 Gew.-% Wasser enthält. Das Gewicht des trockenen Silikagel wird bestimmt, indem man das mit Feuchtigkeit beladene Silikagel solange einer Temperatur von 160° C aussetzt, bis das Gewicht des Silikagel konstant bleibt, und darauf sein Trockengewicht feststellt.It is also advantageous to use a silica gel which, at an equilibrium of 20 ° C. and 50% relative atmospheric humidity, based on the dry substance of the silica gel, contains 5 to 18% by weight, preferably about 8% by weight, of water. The weight of the dry silica gel is determined by exposing the moisture-laden silica gel to a temperature of 160 ° C. until the weight of the silica gel remains constant and then determining its dry weight.
Es ist ausserdem zweckmässig, wenn man das mit Aromastoffen beladene Silikagel in mindestens einem Teil eines Zigarettenfilters anordnet. Dabei ist es vorteilhaft, wenn man das mit Aromastoffen und Propylenglykol beladene Silikagel mindestens in einen Teil des für ein Zigarettenfilter, zum Beispiel Doppelfilters, bestimmten Filtermaterials einarbeitet.It is also expedient if the silica gel laden with flavorings is arranged in at least part of a cigarette filter. It is advantageous if the silica gel loaded with flavorings and propylene glycol is incorporated into at least part of the filter material intended for a cigarette filter, for example a double filter.
Gegenstand der vorliegenden Erfindung ist ferner ein Zigarettenendstück, insbesondere Zigarettenfilter, zur Durchführung des erfindungsgemässen Verfahrens, welches dadurch gekennzeichnet ist, dass es eine mindestens das mit Aromastoffen und Propylenglykol beladene, granulatförmige Silikagel enthaltende Kammer aufweist.The present invention also relates to a cigarette end piece, in particular a cigarette filter, for carrying out the method according to the invention, which is characterized in that it has a chamber containing at least the granular silica gel loaded with flavorings and propylene glycol.
Gegenstand der vorliegenden Erfindung ist ausserdem eine Verwendung des erfindungsgemässen Verfahrens zur Anetholisierung von Tabakrauch.The present invention also relates to a use of the method according to the invention for the anetholization of tobacco smoke.
Unter Standardbedingungen, das heisst alle Minuten ein Zug von 35ml Volumen und von 2 Sekunden Dauer, wurden Filterzigaretten der gleichen Marke und mit der gleichen Feuchtigkeit abgeraucht, und parallel dazu von Testpersonen auf den Geschmack überprüft, wobei in den dabei verwendeten Kammerfiltern einerseits mit Anethol beladene, aus Kokosnuss hergestellte Aktivkohle und anderseits erfindungsgemäss mit Anethol und Propylenglykol beladenes, granulatförmiges, hochporöses Silikagel eingefüllt war.Under standard conditions, that is, a train of 35 ml volume and a duration of 2 seconds every minute, filter cigarettes of the same brand and with the same humidity were smoked, and the taste was checked in parallel by test persons, with the chamber filters used being loaded with anethole , activated carbon made from coconut and, on the other hand, granular, highly porous silica gel loaded with anethole and propylene glycol according to the invention.
Dabei ergaben sich folgende Ergebnisse:
Wie man sieht, kann man bei Verwendung von Silikagel als Träger- und Speichermaterial für das Anethol und das Deaktivierungsmittel bereits mit einer geringen Beladungsmenge von 10 Gew.-% Anethol (bezogen auf das Gewicht des unbeladenen Silikagels) eine einwandfreie Aromatisierung des Rauches erreichen, wenn die Optimierungsregel beachtet wird, dass Aromastoff und Desaktivierungsmittel zusammen etwa 30 Gew.-%, bezogen auf das unbeladene Silikagel, ausmachen. Da das Deaktivierungsmittel Propylenglykol bedeutend billiger ist als Anethol, ist dies auch aus Kostengründen interessant. Bei der Verwendung von Aktivkohle als Träger- und Speichermaterial für das Anethol ist es unmöglich, mit 10 Gew.-% Anethol auf irgend eine Weise eine Aromatisierung des Rauches zu erzielen.As can be seen, when using silica gel as a carrier and storage material for the anethole and the deactivating agent, a perfect flavoring of the smoke can be achieved with a small loading amount of 10% by weight of anethole (based on the weight of the unloaded silica gel), if the optimization rule is observed that the flavoring agent and the deactivating agent together make up about 30% by weight, based on the unloaded silica gel. Since the deactivating agent propylene glycol is significantly cheaper than anethole, this is also interesting for cost reasons. When using activated carbon as a carrier and storage material for the anethole, it is impossible to flavor the smoke in any way with 10% by weight of anethole.
Zur Ueberprüfung der Lagerungsfähigkeit wurde ferner der unter Standardbedingungen beim Abrauchen von mit einem mit hochporösem, mit 10 Gew.-% Anethol und 20 Gew.-% Propylenglykol Gew-% (jeweils bezogen auf das Gewicht des unbeladenen Trägermaterials) beladenen granulatförmigen Silikagel enthaltenden Kammerfiltern versehenen Zigaretten bei neun Zügen im Rauch in Partikularphase vorhandene Anetholgehalt bestimmt, und zwar kurz nach der Beladung des verwendeten Silikagels und nochmals nach etwa drei Monaten, wobei beide Male eine Anetholmenge (in Partikularphase) von 0,44mg/Zigarette festgestellt wurde. Dabei wurde ein unter der Handelsbezeichnung "Polygel W-45" von der Firma Chemische Fabrik Uetikon, Uetikon (Schweiz) hergestelltes Silikagel mit einer spezifischen Oberfläche von 550m2/g Silikagel und einem Porenvolumen von 0,73ml/g Silikagel verwendet.To check the shelf life, the chamber filters were provided under standard conditions when smoking with a highly porous, containing 10 wt .-% anethole and 20 wt .-% propylene glycol wt .-% (each based on the weight of the unloaded carrier material) Cigarettes in nine puffs of smoke in the particulate phase determined the presence of anethole, shortly after loading the silica gel used and again after about three months, both times with an amount of anethole (in particulate phase) of 0.44 mg / cigarette. A silica gel produced under the trade name "Polygel W-45" by the company Chemische Fabrik Uetikon, Uetikon (Switzerland) with a specific surface area of 550 m 2 / g silica gel and a pore volume of 0.73 ml / g silica gel was used.
Anstatt das mit einem Aromastoff und Propylenglykol beladene Silikagel in die Kammer eines Kammerfilters einzufüllen, ist es auch möglich, dieses in einem in axialer Richtung mittels zweier Abschlusswandungen, deren Filterwirkung vernachlässigbar ist, verschlossenen Mund- oder Endteil vorzusehen, so dass zum Beispiel der Teer-und Nikotingehalt des durchströmenden Rauches praktisch nicht verändert wird und somit dem Rauch einer filterlosen Zigarette entspricht, anderseits der durchströmende Rauch jedoch zusätzlich aromatisiert wird.Instead of filling the silica gel loaded with a flavoring substance and propylene glycol into the chamber of a chamber filter, it is also possible to provide this in a mouth or end part which is closed in the axial direction by means of two end walls, the filter effect of which is negligible, so that, for example, the tar and nicotine content of the flowing smoke is practically unchanged and thus corresponds to the smoke of a filterless cigarette, but on the other hand the flowing smoke is additionally flavored.
Es ist auch möglich, das mit einem Aromastoff und Propylenglykol beladene Silikagel bei der Herstellung eines Zigarettenfilters mittels einem Haftmittel zwischen den Fasern des filtermaterialstranges anzuordnen. Bei einem Doppelfilter würde man das mit Aromastoffen und Propylenglykol beladene Trägermaterial vorzugsweise in dem Tabakteil der Filterzigarette benachbarten Stöpsel des Filters anordnen.It is also possible to arrange the silica gel loaded with a flavoring agent and propylene glycol in the manufacture of a cigarette filter by means of an adhesive between the fibers of the filter material strand. In the case of a double filter, the carrier material loaded with flavorings and propylene glycol would preferably be arranged in the tobacco part of the filter cigarette next to the plug of the filter.
