Definitions
- the invention relates to a ventilated filter cigarette with a predominant "American blend" taste and is based on the already inventive object of proposing such a cigarette exclusively based on Virginia tobacco types, the main stream smoke of which has a condensate / nicotine ratio of 5: 1 to 9: 1 with a condensate value according to DIN 10240 of at most 10 mg, a pH value of over 6.0 and a pollutant index (SI) according to Herzfeld below 35.
- SI pollutant index
- Cigarettes with the typical "American blend" taste are preferred by certain consumer groups, but because of the Burley tobacco used, they have the disadvantage that, because of the higher protein content, they give rise to more disruptive factors with regard to the aroma and additionally have a significantly higher nitrate content. This leads to a relatively high pollutant index according to Herzfeld.
- a high filter ventilation can result in such a dilution of the main flow smoke that the values determined according to the standards result in low condensate and nicotine values and a low pollutant index.
- such cigarettes have the disadvantage of a low tobacco taste, an aroma deficit, show a low degree of saturation and consequently have only a low level of consumer acceptance.
- EU-A 0 255 114 it is known to provide special filter constructions and in particular those with chamber filters which are said to result in improved taste properties and a more favorable nicotine / condensate ratio with a maximum of 8 mg of condensate.
- ventilated mono-filter cigarettes according to DE-OS 30 11 959 are to lead to specially designed groove filters and the resulting lashing movement of the main stream smoke emerging from the filter body to cigarettes with a stronger aroma sensation with lower nicotine and condensate values.
- filter cigarettes with such a construction are expensive the flavor did not change in type, but at most weakened.
- the taste characteristics of the existing tobacco mixture can be found in a more or less weakened form, naturally also in the mainstream smoke and, in the opinion of the average expert, cannot be converted into another taste.
- the inventive task mentioned at the outset is also intended to achieve a ventilated filter cigarette with low condensate values, and in particular a low pollutant index, without having to accept the disadvantages known to the person skilled in the art, such as a low tobacco taste, aroma deficit, low degree of saturation and thus one poor consumer acceptance with relatively production-intensive measures.
- a happy grip gives a ventilated filter cigarette with a predominant "American blend” taste with condensate / nicotine values or pollutant values completely atypical for this taste , namely through a partially (max.
- volume-activated tobacco mixture with appropriately adapted strand equipment and strand density, through the use of an inexpensive filter with high draw resistance and preferably a monoacetate filter with high retention capacity with the resulting high cigarette end draw resistance Selection of virgin Virginia tobacco of high quality with a high nicotine and sugar content, which result in a low pollutant index with a high degree of saturation even with a relatively low degree of filter ventilation, whereby - completely unexpected for the expert - an intense "American blend" flavor with only one Use of virgin Virginia tobacco is obtained.
- the nicotine content of natural Virginia tobacco influences the taste component "reaction” or “strength” and is in the range of 1.7 to 2.3%, based on the dry substance, of commercially available cigarettes.
- a high to unusually high nicotine content of 2 to 3.5% by weight is intentionally provided.
- the packing density of the filling tobacco for standard cigarettes is in a range from 220 to 280 mg / cm3, corresponding to a cigarette hardness range of approx. 2.5 to 1.9 mm ET (test stamp penetration depth) according to the Reemtsma hardness measuring device, that in principle the digital -Densimeter DD-30 (with cigarette equipment) from Heinrich Borgwaldt / Hamburg.
- a "sharper" taste With a low packing density in the lower range of 150 mg / cm 3, a "sharper" taste generally arises, while in the usual range from 220 to 280 mg, the strand absorption increases and thus suppresses or levels out the "sharper” taste by practically additional filter action. This can also apply to other taste impressions.
- the air permeability of the cigarette paper in CORESTA values according to DIN / ISO 2965 for commercially available cigarettes is in a range from 25 to 70, whereby at low CORESTA values there is only a low smoldering ability and only little ventilation, and consequently only a small dilution of the smoke the Cigarette paper is given, while at high CORESTA values a high glow rate is made possible with strong ventilation.
- this parameter is set below the market range of at least 25 CORESTA, namely to a value of 3 to 20.
- fine-titered cellulose acetate filters provided with customary hardnesses are used without flavor-changing additives, but the parameters to be observed here are also of considerable influence.
- the individual titer of the filter material is approximately 2.5 to 3.5 denier, it being known that a low individual titer of approximately 1.3 denier results in a relatively high sorption and a relatively large retention with a relatively high tensile resistance, while correspondingly higher denier numbers with otherwise the same parameters lead to lower sorption and lower retention and lower tensile resistance.
- the individual titer in the cigarettes according to the invention is in a range from 1.3 to 2.5 denier, that is to say below the customarily used single titer.
- the total titer influencing the absolute tensile resistance is in the range of 32,000 to 40,000 denier for standard cigarettes, whereby the absolute sorption or retention or the absolute tensile resistance - neglecting the ripple index - is directly proportional to the total titer.
- the resulting filter draw resistance is in the range of 50 to 70 daPa for commercially available cigarettes and results in a correspondingly small change in taste at low values and a significant change in taste towards "light" at higher values.
- the tensile resistances to be coordinated over the total titer in the case of the extremely low individual titer values required for the invention are 95-160 daPa in a deliberately high, unusual range.
- the degree of additional air ie the ratio of additional air to main flow smoke, is in the range of 10 to 50% for standard cigarettes; an increase in the supply air to, for example, 75% results in a strong change in taste in the direction of "super-mild".
- the supply air is at a filter ventilation level of 20 to 45%, that is to say in a medium range.
- the final pull resistance of the majority of commercially available filter cigarettes is in a range from 80 to 120 daPa. With conventional light cigarettes, higher ultimate tensile resistances have an unusual and therefore negative effect on consumers.
- the final pull resistance of 100 to 160 daPa selected for the cigarette according to the invention is intentionally in the upper range in order to influence the pollutant index. Surprisingly, however, the unusually high final pull resistance of the cigarette according to the invention was not perceived as negative in in-house tests.
- Test cigarettes were made from pure Virginia tobacco without flavor-changing additives and without flavoring agents, but with the usual proportions of a humectant.
- the tobacco feed weight of the strands produced in the usual format was 690 mg; the cigarette paper used had a permeability of 20 CORESTA units; the packing density of the filling tobacco was set to 220 mg / cm3, the strand having a well-stuffed degree of filling with a usual hardness value of 2.2 mm ET.
- the hardness of standard cigarettes measured with the same hardness measuring device is between 1.9 and 2.5 mm ET in a standard climate.
- a monoacetate filter with a titer of 1.5 Y / 46,000 SK denier was used as the filter, its tensile resistance being 21 mm in length and approximately 7.8 mm in diameter being approximately 118 daPa.
- the format of the finished filter cigarette was 7.90 mm ⁇ x 84 mm in length; the degree of additional air was 37% and the final pull resistance was 130 daPa.
- the cigarette smoked according to DIN 10240 produced 7.95 mg condensate and 1.0 mg nicotine with a number of 10 puffs, which corresponded to a K / N ratio of approx. 8: 1.
- the pH of this cigarette was 6.4. In view of the typical smoke pH value of a Virginia cigarette of at most 5.5, this value is exceptionally high.
- the Herzfeld pollutant index determined for these cigarettes was approx. 31 and was calculated using the following formula:
- a tobacco stick made of the same natural Virginia tobacco mixture with the same packing density was used with a cigarette paper with the same low air permeability of 20 CORESTA, but with a conventional ventilated cellulose acetate filter with medium single and total titer and corresponding medium tensile resistance and a consequent result medium filter retention, but with a comparatively high degree of filter ventilation, i.e. a high smoke dilution.
- This cigarette which was smoked in accordance with DIN 10240, produced condensate values comparable to those of the filter cigarette according to Example 1. With a cigarette of this type, as was actually expected, there was no typical "American blend" taste; it tasted significantly like Virginia tobacco, albeit fuller and more aromatic than a conventional Virginia cigarette.
- Example 1 In a further sensory comparison test, a filter according to Example 1 was combined with a conventional Virginia strand, a clear Virginia taste note being obtained, but the taste performance of which was unsatisfactory and weak.

Abstract
Description
Die Erfindung betrifft eine ventilierte Filtercigarette mit vorherrschendem "American-Blend"-Geschmack und beruht auf der bereits erfinderischen Aufgabe, eine solche Cigarette ausschließlich auf Basis von Virginia-Tabaksorten vorzuschlagen, deren Hauptstromrauch ein Kondensat/Nikotin-Verhältnis von 5:1 bis 9:1 bei einem Kondensatwert nach DIN 10240 von höchstens 10 mg, einen pH-Wert von über 6,0 und einen Schadstoffindex (SI) nach Herzfeld unter 35 aufweist.The invention relates to a ventilated filter cigarette with a predominant "American blend" taste and is based on the already inventive object of proposing such a cigarette exclusively based on Virginia tobacco types, the main stream smoke of which has a condensate / nicotine ratio of 5: 1 to 9: 1 with a condensate value according to DIN 10240 of at most 10 mg, a pH value of over 6.0 and a pollutant index (SI) according to Herzfeld below 35.
Cigaretten mit dem typischen "American-Blend"-Geschmack werden von bestimmten Verbraucherkreisen bevorzugt, haben aber wegen des verwendeten Burley-Tabaks den Nachteil, daß sie wegen des höheren Proteingehaltes im Hinblick auf das Aroma mehr Störfaktoren ergeben und zusatzlich einen deutlich höheren Nitratgehalt aufweisen. Das führt zu einem verhältnismäßig hohen Schadstoffindex nach Herzfeld.Cigarettes with the typical "American blend" taste are preferred by certain consumer groups, but because of the Burley tobacco used, they have the disadvantage that, because of the higher protein content, they give rise to more disruptive factors with regard to the aroma and additionally have a significantly higher nitrate content. This leads to a relatively high pollutant index according to Herzfeld.
Es ist zwar möglich, Virginia-Tabaksorten mit Burley-Tabaksorten zu vermischen um den gewünschten "American-Blend"-Geschmack zu erhalten oder gar durch Zusatz tabakfremder Additive zu steigern, jedoch ist dieser letzte Weg insbesondere im Hinblick auf die Tabakverordnung begrenzt, zumal durch unvollständige Verbrennung bzw. Pyrolyse derartiger tabakfremder Additive unverwünschte Schadstoffe entstehen können, die zu einem höheren Schadstoffindex führen.Although it is possible to mix Virginia tobacco varieties with Burley tobacco varieties in order to obtain the desired "American blend" taste or even to increase it by adding non-tobacco additives, this last route is particularly limited with regard to the tobacco regulation, especially by Incomplete combustion or pyrolysis of such non-tobacco additives can result in unwanted pollutants that lead to a higher pollutant index.
Ferner kann man bekanntlich durch eine hohe Filterventilation eine solche Verdünnung des Hauptstromrauches erhalten, daß die nach den Normen ermittelten Werte niedrige Kondensat- und Nikotinwerte und einen niedrigen Schadstoffindex ergeben. Derartige Cigaretten haben jedoch den Nachteil eines geringen Tabakgeschmacks, eines Aromadefizites, zeigen einen niedrigen Sättigungsgrad und haben demzufolge eine nur geringe Konsumentenakzeptanz.Furthermore, as is known, a high filter ventilation can result in such a dilution of the main flow smoke that the values determined according to the standards result in low condensate and nicotine values and a low pollutant index. However, such cigarettes have the disadvantage of a low tobacco taste, an aroma deficit, show a low degree of saturation and consequently have only a low level of consumer acceptance.
Es ist auch beispielsweise gemäß EU-A 0 255 114 bekannt, spezielle Filterkonstruktionen und insbesondere solche mit Kammerfiltern vorzusehen, die verbesserte Geschmackseigenschaften, ein günstigeres Nikotin/Kondensat-Verhältnis bei maximal 8 mg Kondensat ergeben sollen. Ferner sollen belüftete Mono-Filter-Cigaretten gemäß DE-OS 30 11 959 durch besonders konstruierte Rillenfilter und eine dadurch bedingte peitschende Bewegung des aus dem Filterkörper austretenden Hauptstromrauches zu Cigaretten mit einem stärkeren Aromaempfinden bei geringeren Nikotin- und Kondensatwerten führen. Abgesehen davon, daß diese Ergebnisse kaum reproduzierbar oder zumindest umstritten sind, wird mit derartig konstruktiv aufwendigen Filtercigaretten die Geschmacksrichtung nicht in ihrem Typ geändert, sondern höchstens abgeschwächt.According to EU-A 0 255 114, for example, it is known to provide special filter constructions and in particular those with chamber filters which are said to result in improved taste properties and a more favorable nicotine / condensate ratio with a maximum of 8 mg of condensate. Furthermore, ventilated mono-filter cigarettes according to DE-OS 30 11 959 are to lead to specially designed groove filters and the resulting lashing movement of the main stream smoke emerging from the filter body to cigarettes with a stronger aroma sensation with lower nicotine and condensate values. Apart from the fact that these results are hardly reproducible or at least controversial, filter cigarettes with such a construction are expensive the flavor did not change in type, but at most weakened.
In allen Fällen findet sich die Geschmackstypik der vorhandenen Tabakmischung in mehr oder weniger abgeschwächter Form naturgemäß auch im Hauptstromrauch wieder und läßt sich nach Auffassung des Durchschnittsfachmannes nicht in eine andere Geschmacksrichtung umwandeln.In all cases, the taste characteristics of the existing tobacco mixture can be found in a more or less weakened form, naturally also in the mainstream smoke and, in the opinion of the average expert, cannot be converted into another taste.
Mit der eingangs erwähnten erfinderischen Aufgabenstellung soll zusätzlich erreicht werden, eine ventilierte Filtercigarette mit niedrigen Kondensatwerten, und insbesondere einen niedrigen Schadstoffindex, zu erhalten, ohne die dem Fachmann bekannten Nachteile in Kauf nehmen zu müssen, wie geringer Tabakgeschmack, Aromadefizit, niedriger Sättigungsgrad und damit eine schlechte Konsumentenakzeptanz bei verhältnismäßig produktionsaufwendigen Maßnahmen.The inventive task mentioned at the outset is also intended to achieve a ventilated filter cigarette with low condensate values, and in particular a low pollutant index, without having to accept the disadvantages known to the person skilled in the art, such as a low tobacco taste, aroma deficit, low degree of saturation and thus one poor consumer acceptance with relatively production-intensive measures.
Zur Lösung dieser Aufgabe wird eine ventilierte Filtercigarette vorgeschlagen, die durch die angegebene Kombination der verschiedenen Merkmale gemäß Patentanspruch gekennzeichnet ist.To solve this problem, a ventilated filter cigarette is proposed, which is characterized by the specified combination of the various features according to the patent claim.
Überraschenderweise wird durch Kombination an sich bekannter aber zum Teil an der Grenze oder außerhalb der Bereiche der Parameter liegender Merkmale durch einen glücklichen Griff eine ventilierte Filtercigarette mit vorherrschendem "American-Blend"-Geschmack bei für diesen Geschmack völlig atypischen Kondensat/Nikotinwerten bzw. Schadstoffwerten erhalten, und zwar durch eine teilweise (max. 75 %) volumenaktivierte Tabakmischung mit entsprechend angepaßter Strangausstattung und Strangdichte, durch Einsatz eines kostengünstigen Filters mit hohem Zugwiderstand und vorzugsweise eines Monoacetatfilters mit hoher Retentionsleistung mit dem daraus resultierenden hohen Cigarettenendzugwiderstand, durch Auswahl von naturbelassenen Virginia-Tabaken hoher Qualität mit hohem Nikotin- und Zuckergehalt, die selbst bei Verhältnismäßig niedrigem Filterventilationsgrad einen niederen Schadstoffindex bei gleichzeitig hohem Sättigungsgrad ergeben, wobei - für den Fachmann völlig unerwartet - eine intensive "American-Blend"-Ge schmacksrichtung bei ausschließlichem Einsatz von reinen Virginia-Tabaken erhalten wird.Surprisingly, by combining features which are known per se but are in part at the limit or outside the ranges of the parameters, a happy grip gives a ventilated filter cigarette with a predominant "American blend" taste with condensate / nicotine values or pollutant values completely atypical for this taste , namely through a partially (max. 75%) volume-activated tobacco mixture with appropriately adapted strand equipment and strand density, through the use of an inexpensive filter with high draw resistance and preferably a monoacetate filter with high retention capacity with the resulting high cigarette end draw resistance Selection of virgin Virginia tobacco of high quality with a high nicotine and sugar content, which result in a low pollutant index with a high degree of saturation even with a relatively low degree of filter ventilation, whereby - completely unexpected for the expert - an intense "American blend" flavor with only one Use of virgin Virginia tobacco is obtained.
Zu den einzelnen Parametern bzw. Merkmalen der bei der erfindungsgemäßen ventilierten Filtercigarette verwendeten Kombination ist folgendes anzumerken:The following should be noted regarding the individual parameters or features of the combination used in the ventilated filter cigarette according to the invention:
Der Nikotingehalt von naturbelassenem Virginia-Tabak beeinflußt im Geschmack die Geschmackskomponente "Reaktion" bzw. "Kraft" und liegt bei marktüblichen Cigaretten in einem Bereich von 1,7 bis 2,3 %, bezogen auf die Trockensubstanz. Bei der erfindungsgemäßen Cigarette wird absichtlich ein hoher bis unüblich hoher Nikotingehalt von 2 bis 3,5 Gew. % vorgesehen.The nicotine content of natural Virginia tobacco influences the taste component "reaction" or "strength" and is in the range of 1.7 to 2.3%, based on the dry substance, of commercially available cigarettes. In the cigarette according to the invention, a high to unusually high nicotine content of 2 to 3.5% by weight is intentionally provided.
Die Packungsdichte des Fülltabaks liegt bei marktüblichen Cigaretten in einem Bereich von 220 bis 280 mg/cm³, entsprechend einem Cigarettenhärte-Bereich von ca. 2,5 bis 1,9 mm ET (Prüfstempel Eindringtiefe) gemäß Reemtsma-Härtemeßgerät, daß im Prinzip dem Digital-Densimeter DD-30 (mit Cigarettenausrüstung) der Fa. Heinrich Borgwaldt/Hamburg entspricht. Bei einer geringen Packungsdichte im unteren Bereich von 150 mg/cm³ entsteht im allgemeinen ein "schärferer" Geschmack, während in dem üblichen Bereich von 220 bis 280 mg die Strangsorption ansteigt und damit durch praktisch zusätzliche Filterwirkung den "schärferen" Geschmack herabdrückt bzw. nivelliert. Dies kann auch für andere Geschmackseindrucke gelten.The packing density of the filling tobacco for standard cigarettes is in a range from 220 to 280 mg / cm³, corresponding to a cigarette hardness range of approx. 2.5 to 1.9 mm ET (test stamp penetration depth) according to the Reemtsma hardness measuring device, that in principle the digital -Densimeter DD-30 (with cigarette equipment) from Heinrich Borgwaldt / Hamburg. With a low packing density in the lower range of 150 mg / cm 3, a "sharper" taste generally arises, while in the usual range from 220 to 280 mg, the strand absorption increases and thus suppresses or levels out the "sharper" taste by practically additional filter action. This can also apply to other taste impressions.
Die Luftdurchlässigkeit des Cigarettenpapiers liegt in CORESTA-Werten nach DIN/ISO 2965 bei marktüblichen Cigaretten in einem Bereich von 25 bis 70, wobei bei niedrigen CORESTA-Werten eine nur geringe Glimmfähigkeit und eine nur geringe Ventilation, auch demzufolge eine nur geringe Verdünnnung des Rauches durch das Cigarettenpapier gegeben ist, während bei hohen CORESTA-Werten eine hohe Glimmgeschwindigkeit bei starker Ventilation ermöglicht wird. Dieser Parameter wird bei den erfindungsgemäßen Cigaretten unterhalb des marktüblichen Bereiches von mindestens 25 CORESTA, nämlich auf einen Wert von 3 bis 20 eingestellt.The air permeability of the cigarette paper in CORESTA values according to DIN / ISO 2965 for commercially available cigarettes is in a range from 25 to 70, whereby at low CORESTA values there is only a low smoldering ability and only little ventilation, and consequently only a small dilution of the smoke the Cigarette paper is given, while at high CORESTA values a high glow rate is made possible with strong ventilation. In the case of the cigarettes according to the invention, this parameter is set below the market range of at least 25 CORESTA, namely to a value of 3 to 20.
Bei der erfindungsgemäßen Cigarette werden zwar mit üblichen Härten versehene feintitrige Celluloseacetatfilter ohne geschmacksverändernde Zusätze eingesetzt, jedoch sind auch die hier zu beachtenden Parameter von wesentlichem Einfluß.In the cigarette according to the invention, fine-titered cellulose acetate filters provided with customary hardnesses are used without flavor-changing additives, but the parameters to be observed here are also of considerable influence.
Bei marktüblichen Cigaretten beträgt der Einzeltiter des Filtermaterials etwa 2,5 bis 3,5 Denier, wobei es bekannt ist, daß ein niedriger Einzeltiter von etwa 1,3 Denier eine relativ hohe Sorption und eine relativ große Retention bei relativ hohem Zugwiderstand ergibt, während entsprechend höhere Denier-Zahlen bei sonst gleichen Parametern zu einer niedrigeren Sorption und niedrigerer Retention und einem geringeren Zugwiderstand führen. Im Hinblick auf den Titerbereich der Filter von marktüblichen Cigaretten von 2,5 bis 3,5 Denier liegt bei den erfindungsgemäßen Cigaretten der Einzeltiter in einem Bereich von 1,3 bis 2,5 Denier, also unterhalb der üblicherweise verwendeten Einzeltiter.In commercially available cigarettes, the individual titer of the filter material is approximately 2.5 to 3.5 denier, it being known that a low individual titer of approximately 1.3 denier results in a relatively high sorption and a relatively large retention with a relatively high tensile resistance, while correspondingly higher denier numbers with otherwise the same parameters lead to lower sorption and lower retention and lower tensile resistance. With regard to the titer range of the filters of commercially available cigarettes from 2.5 to 3.5 denier, the individual titer in the cigarettes according to the invention is in a range from 1.3 to 2.5 denier, that is to say below the customarily used single titer.
Der den absoluten Zugwiderstand beeinflussende Gesamttiter liegt bei marktüblichen Cigaretten in einem Bereich von 32.000 bis 40.000 Denier, wobei die absolute Sorption bzw. Retention oder der absolute Zugwiderstand - unter Vernachlässigung des Kräusel-Index - direkt proportional zum Gesamttiter ist. Der sich ergebende Filter-Zugwiderstand liegt bei marktüblichen Cigaretten in einem Bereich von 50 bis 70 daPa und ergibt bei niedrigen Werten eine entsprechend geringe Geschmacksänderung und bei höheren Werten eine deutliche Geschmacksänderung in Richtung auf "leicht". Die bei den erfindungsgemäß geforderten überaus niedrigen Einzeltiterwerten über den Gesamttiter abzustimmenden Zugwiderstände liegen bei der erfindungsgemäßen Cigarette mit 95 - 160 daPa in einem gewollt hohen unüblichen Bereich.The total titer influencing the absolute tensile resistance is in the range of 32,000 to 40,000 denier for standard cigarettes, whereby the absolute sorption or retention or the absolute tensile resistance - neglecting the ripple index - is directly proportional to the total titer. The resulting filter draw resistance is in the range of 50 to 70 daPa for commercially available cigarettes and results in a correspondingly small change in taste at low values and a significant change in taste towards "light" at higher values. With the cigarette according to the invention, the tensile resistances to be coordinated over the total titer in the case of the extremely low individual titer values required for the invention are 95-160 daPa in a deliberately high, unusual range.
Der Beiluftgrad, also das Verhältnis von Beiluft zu Hauptstromrauch, liegt bei marktüblichen Cigaretten in einem Bereich von 10 bis 50 %; eine Erhöhung der Beiluftzufuhr auf beispielsweise 75 % ergibt eine starke Geschmacksänderung in Richtung "super-mild" Bei der erfindungsgemäßen Cigarette liegt die Beiluftzufuhr bei einem Filterventilationsgrad von 20 bis 45 %, also in einem mittleren Bereich.The degree of additional air, ie the ratio of additional air to main flow smoke, is in the range of 10 to 50% for standard cigarettes; an increase in the supply air to, for example, 75% results in a strong change in taste in the direction of "super-mild". In the cigarette according to the invention, the supply air is at a filter ventilation level of 20 to 45%, that is to say in a medium range.
Der Endzugwiderstand des Gros marktüblicher Filtercigaretten liegt in einem Bereich von 80 bis 120 daPa. Höhere Endzugwiderstände wirken gerade bei herkömmlichen leichten Cigaretten auf den Konsumenten ungewohnt und damit negativ. Der bei der erfindungsgemäßen Cigarette ausgewählte Endzugwiderstand von 100 bis 160 daPa liegt absichtlich im oberen Bereich, um den Schadstoffindex zu beeinflussen. Überraschenderweise wurde jedoch der unüblich hohe Endzugwiderstand der erfindungsgemäßen Cigarette bei hausinternen Tests nicht als negativ empfunden.The final pull resistance of the majority of commercially available filter cigarettes is in a range from 80 to 120 daPa. With conventional light cigarettes, higher ultimate tensile resistances have an unusual and therefore negative effect on consumers. The final pull resistance of 100 to 160 daPa selected for the cigarette according to the invention is intentionally in the upper range in order to influence the pollutant index. Surprisingly, however, the unusually high final pull resistance of the cigarette according to the invention was not perceived as negative in in-house tests.
Warum man bei einer ventilierten Filtercigarette aus reinem naturbelassenen Virginia-Tabak mit hohem Nikotingehalt durch spezielle Auswahl der Packungsdichte des Fülltabaks im unteren Bereich oder unterhalb des marktüblichen Bereiches, bei Auswahl eines Cigarettenpapiers mit einer marktunüblich niedrigen Luftdurchlässigkeit und bei einem Filter mit einem ebenfalls marktunüblich niedrigen Einzeltiter und durch den darauf abgestimmten Gesamttiter wiederum marktunüblich hohen Zugwiderstand bei normalem Beiluftgrad eine Umwandlung der Geschmacksrichtung von Virginia- auf "American-Blend"-Geschmack erhält, ist überraschend.Why with a ventilated filter cigarette made from pure virgin Virginia tobacco with a high nicotine content by choosing the packing density of the filling tobacco in the lower range or below the range customary in the market, when choosing a cigarette paper with an air permeability that is unusually low in the market and with a filter that also has an unusually low individual titre and the overall titre, which is matched to this, in turn leads to a conversion of the flavor from Virginia to "American blend" taste, which is unusually high in the market with a normal degree of draft, which is surprising.
Es ist zwar anzunehmen, daß das durch die Änderung der oben erwähnten Parameter im Hauptstromrauch erhaltene unübliche Kondensat/Nikotin-Verhältnis von 5:1 bis 9:1 den vergleichsweise hohen Rauch-pH-Wert von über 6 begünstigt, was wiederum trotz maximal 10 mg Kondensat, sowie bei einem geringen Schadstoffindex von weniger als 35 den erstaunlich hohen konsumentenrelevanten Sättigungsgrad - nicht jedoch die "Geschmacks-Inversion" - erklären mag.It can be assumed that the unusual condensate / nicotine ratio of 5: 1 to 9: 1 obtained by changing the above-mentioned parameters in the main flow smoke favors the comparatively high smoke pH value of over 6, which in turn despite a maximum of 10 mg Condensate, and with a low pollutant index of less than 35 may explain the astonishingly high degree of saturation relevant to consumers - but not the "taste inversion".
Bei der Komplexität der verschiedenen Parameter von relevanten Tabakinhaltsstoffen, Tabak-Packungsdichte, Luftdurchlässigkeit des Cigarettenpapiers sowie Einzeltiter, Gesamttiter und Zugwiderstand des Celluloseacetatfilters in Zusammenhang mit dem Endzugwiderstand läßt sich nur annehmen, daß anteilig die eingesetzten naturbelassenen Virginia-Tabake, die im Gegensatz zu den meisten handelsüblichen Tabakmischungen keiner chemothermischen Behandlung unterzogen worden sind, bedingt durch den damit Verbundenen verhältnismäßig hohen Restzuckergehalt sowie durch den zusätzlichen gewollt ausgewählten hohen Nikotingehalt bei gleichzeitig geringem Nitrat und NH₃-Gehalt, durch die gemäß DE-PS 34 14 625 durchgeführte Steigerung der Füllfähigkeit bzw. Volumenaktivierung einen höheren Anteil von nunmehr aufgeschlossenen Aromastoffen bzw. deren Precursoren enthalten. Wenn dann ein Verhältnismäßig nieder-poröses Cigarettenpapier mit einer Luftdurchlässigkeit unter 20 CORESTA vorgesehen wird und mit einem - bezogen auf den niederen Schadstoffindex - erstaunlich niederen Filterventilationsgrad von etwa 20 bis 45 % kombiniert wird, wird bei der so ausgewählten Mischung in Kombination mit einer auf die Tabakauswahl und Ausstattung abgestimmten Strangdichte eine anscheinend optimale Glutzonentemperatur ermöglicht, bei der ein Großteil der aufgeschlossenen Aromastoffe oder deren Precursoren freigesetzt bzw. umgewandelt wird. Es ist ferner anzunehmen, daß die gleichzeitig wie bei jedem unvollständigen Verbrennungsprozeß von stickstoffhaltigen organischen Materialien auftretenden sensorischen "Störfaktoren", wie niedere Amine, Aldehyde, Alkoholsäuren oder Ester, die geschmacklich zur typischen Virginia-Note beitragen, nämlich "Schärfe" oder ein "Brennen" hervorrufen, durch den überaus ungewöhnlich feintitrigen Monoacetatfilter mit hoher Retentionsleistung anscheinend überproportional zurückgehalten werden, während die Aromastoffe und die erwünschten Tabakinhaltsstoffe, wie Nikotin und Homologe, erhalten bleiben, welche geschmacklich "Volumen" bzw. "Kraft" und "Aroma" liefern, so daß sich der überraschende Effekt ergibt, daß der Nebenstromrauch der erfindungsgemäßen Cigarette einen erkennbaren Virginia-Geruch, der in den Mund des Rauchers gelangende Hauptstromrauch der gleichen Cigarette jedoch einen typischen "American-Blend"-Geschmack besitzt.Given the complexity of the various parameters of relevant tobacco ingredients, tobacco packing density, air permeability of the cigarette paper as well as individual titer, total titer and tensile resistance of the cellulose acetate filter in connection with the ultimate tensile resistance, it can only be assumed that the natural virginia tobacco used, unlike most, is proportionate Commercial tobacco mixtures have not been subjected to any chemothermal treatment, due to the associated relatively high residual sugar content as well as the additional deliberately chosen high nicotine content with low nitrate and NH₃ content, due to the increase in filling capacity and volume activation carried out according to DE-PS 34 14 625 contain a higher proportion of flavoring substances or their precursors. If a relatively low-porous cigarette paper with an air permeability of less than 20 CORESTA is then provided and combined with an astonishingly low degree of filter ventilation of approximately 20 to 45% in relation to the low pollutant index, the mixture selected in this way is combined with one on the Tobacco selection and equipment matched strand density enables an apparently optimal glowing zone temperature at which a large part of the digested aroma substances or their precursors are released or converted. It is also believed that the same as with any incomplete combustion process sensory "disturbing factors" of nitrogen-containing organic materials, such as lower amines, aldehydes, alcoholic acids or esters, which contribute to the typical Virginia note in terms of taste, namely "sharpness" or "burning", apparently due to the extremely unusually fine titered monoacetate filter with high retention capacity are disproportionately retained, while the flavorings and the desired tobacco constituents, such as nicotine and homologs, are retained, which provide taste "volume" or "strength" and "aroma", so that there is the surprising effect that the sidestream smoke of the cigarette according to the invention a recognizable Virginia smell, but the mainstream smoke of the same cigarette entering the smoker's mouth has a typical "American blend" taste.
Es wurden Versuchscigaretten aus reinem Virginia-Tabak ohne geschmacksverändernde Additive und ohne Aromastoffe, jedoch mit üblichen Anteilen eines Feuchthaltemittels hergestellt. Das Tabakeinsatzgewicht der im üblichen Format gefertigten Stränge betrug 690 mg; das verwendete Cigarettenpapier hatte eine Durchlässigkeit von 20 CORESTA-Einheiten; die Packungsdichte des Fülltabaks wurde auf 220 mg/cm³ eingestellt, wobei der Strang einen gut gestopften Füllgrad bei einem üblichen Härtewert von 2,2 mm ET aufwies. Die mit dem gleichen Härtemeßgerät gemessenen Härten marktüblicher Cigaretten liegen zwischen 1.9 his 2.5 mm ET bei Normklima.Test cigarettes were made from pure Virginia tobacco without flavor-changing additives and without flavoring agents, but with the usual proportions of a humectant. The tobacco feed weight of the strands produced in the usual format was 690 mg; the cigarette paper used had a permeability of 20 CORESTA units; the packing density of the filling tobacco was set to 220 mg / cm³, the strand having a well-stuffed degree of filling with a usual hardness value of 2.2 mm ET. The hardness of standard cigarettes measured with the same hardness measuring device is between 1.9 and 2.5 mm ET in a standard climate.
Als Filter wurde ein Monoacetatflter mit einem Titer von 1,5 Y/46.000 SK-Denier verwendet, wobei sein Zugwiderstand bei 21 mm Länge und ca. 7,8 mm Durchmesser bei etwa 118 daPa lag. Das Format der fertigen Filtercigarette lag bei 7,90 mm ⌀ x 84 mm Länge; der Beiluftgrad lag bei 37 % und der Endzugwiderstand bei 130 daPa.A monoacetate filter with a titer of 1.5 Y / 46,000 SK denier was used as the filter, its tensile resistance being 21 mm in length and approximately 7.8 mm in diameter being approximately 118 daPa. The format of the finished filter cigarette was 7.90 mm ⌀ x 84 mm in length; the degree of additional air was 37% and the final pull resistance was 130 daPa.
Die nach DIN 10240 abgerauchte Cigarette erbrachte bei einer Zugzahl von 10 Zügen 7,95 mg Kondensat und 1,0 mg Nikotin, was einem K/N-Verhältnis von ca 8:1 entsprach. Der pH-Wert dieser Cigarette lag bei 6,4. Im Hinblick auf den typischen Rauch-pH-Wert einer Virginia-Cigarette von höchstens 5,5 ist dieser Wert außergewöhnlich hoch.The cigarette smoked according to DIN 10240 produced 7.95 mg condensate and 1.0 mg nicotine with a number of 10 puffs, which corresponded to a K / N ratio of approx. 8: 1. The pH of this cigarette was 6.4. In view of the typical smoke pH value of a Virginia cigarette of at most 5.5, this value is exceptionally high.
Bei hausinternen Tests wurde die Geschmacksrichtung dieser Cigaretten übereinstimmend als "typisch American-Blend" mit "hohem Sättigungsgrad" (entsprechend den Werten Aroma und Genuß) zugeordnet, und zwar von dem ersten Zug an. Es wurde insbesondere festgestellt, daß die zu erwartenden für Virginia-Tabak spezifischen "Störfaktoren" wie "Schärfe", "Brennen" nicht vorhanden waren.In in-house tests, the taste of these cigarettes was consistently assigned as a "typical American blend" with a "high degree of saturation" (corresponding to the aroma and enjoyment values), from the first puff. In particular, it was found that the expected "disturbing factors" specific to Virginia tobacco, such as "sharpness", "burning", were not present.
Sensorische Vergleichsversuche zeigten, daß die erfindungsgemäßen Cigaretten mit "American-Blend"-Kräftig-Filtercigaretten mit DIN-Werten im Rauch von 15 mg Kondensat und 1 mg Nikotin vergleichbar waren.Sensory comparative tests showed that the cigarettes according to the invention were comparable to "American blend" filter cigarettes with DIN values in smoke of 15 mg condensate and 1 mg nicotine.
Der ermittelte Schadstoffindex nach Herzfeld lag bei diesen Cigaretten bei rd. 31 und wurde nach der folgenden Formel berechnet:
Es wurde ein Tabakstock aus der gleichen naturbelassenen Virginia-Tabak-Mischung bei gleicher Packungsdichte mit einem Cigarettenpapier der gleichen geringen Luftdurchlässigkeit von 20 CORESTA verwendet, jedoch mit einem herkömmlichen ventilierten Celluloseacetatfilter mit mittlerem Einzel- und Gesamttiter und entsprechendem mittleren Zugwiderstand und sich einer demzufolge daraus ergebender mittleren Filterretention, jedoch mit einem vergleichsweise hohen Filterventilationsgrad, also einer hohen Rauchverdünnung, verwendet. Diese nach DIN 10240 abgerauchte Cigarette erbrachte vergleichbare Kondensatwerte wie die Filtercigarette gemäß Beispiel 1. Bei einer derartigen Cigarette ergab sich - eigentlich erwartungsgemäß - kein typischer "American-Blend"-Geschmack; sie schmeckte signifikant nach Virginia-Tabak, wenngleich voller und aromatischer, als eine herkömmliche Virginia-Cigarette.A tobacco stick made of the same natural Virginia tobacco mixture with the same packing density was used with a cigarette paper with the same low air permeability of 20 CORESTA, but with a conventional ventilated cellulose acetate filter with medium single and total titer and corresponding medium tensile resistance and a consequent result medium filter retention, but with a comparatively high degree of filter ventilation, i.e. a high smoke dilution. This cigarette, which was smoked in accordance with DIN 10240, produced condensate values comparable to those of the filter cigarette according to Example 1. With a cigarette of this type, as was actually expected, there was no typical "American blend" taste; it tasted significantly like Virginia tobacco, albeit fuller and more aromatic than a conventional Virginia cigarette.
Bei einem weiteren sensorischen Vergleichsversuch wurde ein Filter gemäß Beispiel 1 mit einem herkömmlichen Virginia-Strang kombiniert, wobei eine eindeutige Virginia-Geschmacksnote erhalten wurde, die aber in ihrer Geschmacksleistung unbefriedigend und schwach wirkte.In a further sensory comparison test, a filter according to Example 1 was combined with a conventional Virginia strand, a clear Virginia taste note being obtained, but the taste performance of which was unsatisfactory and weak.
