Definitions

• the present invention relates to smokable articles which contain special flavoring substances in their wrapping in order to aromatize the sidestream smoke, as well as a wrapping for smokable articles.
• US Pat. No. 4,804,002 proposes treating the wrapping of a smokable article with glycosides of an aroma component, only glucosides of ethyl vanillin, altol and menthol being specifically examined.
• the aroma component is released from the glucoside and can thereby have a positive effect on the smell of the side-stream smoke without the taste impression of the main-stream smoke being changed appreciably.
• the ethylvanillyl-ß-D-glucopyranoside shows primarily
• a cigarette is also known from US Pat. No. 4,941,486, the wrapping of which is in close contact with a bound flavoring agent.
• Ethylvanillin glucoside is used primarily as a bound flavoring agent.
• Impregnation, application of a film, introduction via a size press, electrostatic deposition, printing and incorporation into the seam glue of the cigarette are mentioned as possible methods for applying flavor to the wrapper.
• ethyl vanillin glucoside which is known as a flavoring substance
• the ethyl vanillin released from it produces an aroma which, although certainly pleasant, is clearly perceived as being foreign to tobacco.
• the invention is therefore based on the object to provide smokable articles with flavoring in their wrapping for aromatizing the sidestream smoke, wherein this flavoring does not produce a smell unfamiliar with tobacco when the article is smoked and provides a different aroma than previously known aroma substances and thus that Spectrum for changing the odor of the sidestream smoke expanded.
• the smokable articles according to the invention have an envelope which contains at least one aroma substance for aromatizing the sidestream smoke, and they are distinguished by the fact that the aroma substance is a furaneyl glycoside.
• the invention also relates to a casing for smokable articles, which is characterized by a content of furaneylglycoside.
• furaneol with maltose, lactose or cellobiose are preferably used.
• a particularly preferred furaneyl glycoside is furaneyl glucoside, i.e. a glycoside of furaneol with glucose.
• the chemical name of furaneol is 2, 5-dimethyl-3-hydroxy-4-oxo-4, 5-dihydrofuran.
• the prior art only describes ethyl vanillin as an effective flavoring substance which, at doses above the threshold, leads to a clearly identifiable vanilla note in the bypass smoke. Although this is often perceived as pleasant, it is also perceived as foreign to tobacco. In contrast, the furaneol released from the furaneyl glycoside used when smoking has a completely different odor characteristic. While sweet, caramel-like and bready notes are predominantly perceived in high doses, its smell in low doses is perceived as pleasant, but difficult to identify.
• the articles of the invention preferably contain tobacco as a smokable material. They are therefore especially in the form of cigarettes, cigars and cigarillos.
• furaneyl glycoside in combination with at least one other glycoside of a sugar and an aroma component other than furaneol.
• the released furaneol is able to remove the aroma which is sometimes perceived as tobacco-like, e.g. of ethyl vanillin, without diminishing its positive effects, such as less irritating or stale smoke.
• This other glycoside is, in particular, a glycoside of a double or multiple sugar, since such glycosides can be used even in the form of concentrated solutions without undesired crystallization occurring during their processing. This means that these glycosides can even be applied to the coating in the form of warm solutions using nozzles.
• Maltose, lactose or cellobiose is preferably used as the double or multiple sugar and thus the sugar component of this other glycoside.
• furaneol all flavoring compounds which can be linked to the double or multiple sugar via a glycosidic bond can be used as aroma components of this glycoside.
• Preferred aroma components are vanillin, ethylvanillin, eugenol, menthol or maltol.
• the amount of all glycosides present in the coating is 0.1 to 5% by weight, based on the weight of the coating.
• the wrapping of the articles according to the invention has in particular paper or tobacco. It is particularly advantageously made of paper or film tobacco.
• the wrapping can also be multi-layered, whereby combinations of paper and tobacco can also be used.
• a natural cover sheet can also be used as the outer layer.
• wrapping materials such as e.g. of papers that contain substances to reduce the particle mass of the sidestream smoke.
• special fillers e.g. cigarette papers provided with magnesium hydroxide, magnesium oxide or a mixture thereof.
• the furaneyl glycoside is advantageously applied directly to the paper in the case of a single-layer form and to the outer layer in the case of a two-layer form. In the latter embodiment, it is preferred to use the bypass-reducing paper for the inner layer and conventional cigarette paper for the outer layer.
• the wrapping of the smokable articles according to the invention can in particular also consist of one or two layers of film tobacco. If two-ply film tobacco is used, it is preferred that the outer ply contain the furaneyl glycoside. Accordingly, in the case of cigars and cigarillos, the cover sheet is usually provided with the furaneyl glycoside.
• the smokable articles according to the invention can be produced by providing the coating, in particular in the form of a web, with the furaneyl glycoside and any glycoside present in a sugar and an aroma component other than furaneol.
• glycosides are applied in particular by
• Wrapping materials for smokable articles are usually manufactured according to common paper manufacturing processes. Such methods often provide for one-sided spraying of the paper or tobacco fleece with the aid of a spray bar, which can be used to apply a solution of furaneyl glycoside.
• the possible one-sided application of the glycoside either on the inside or outside of the casing also permits more targeted control of the pyrolytic decomposition.
• a very flexible way of impregnation is also to apply a solution of the furaneyl glycoside in the form of traces to the wrapping directly on the cigarette machine.
• a device required for this is offered, for example, by the company KAYMICH, Sheffield, UK, under the designation FAS or MAS, which is why this process is also referred to as the KAYMICH process.
• the device works with a series of nozzles, which are supplied with the solution by a dosing pump.
• wrappings of film tobacco can also be produced using the so-called slurry process.
• finely ground tobacco dust is mixed with an aqueous solution of binders, scraped onto a heated belt and then dried.
• the furaneyl glycoside can be added to the aqueous binder solution, which results in film tobacco impregnated with it.
• the articles according to the invention are cigarettes or cigarillos provided with a natural cover sheet
• they can be applied either by spraying the cover sheet with an aqueous solution of the glycoside, or else by dissolving the glycoside in that for the gluing between transfer and Cover sheet used glue.

• furaneyl glucoside ((2,5-dimethyl-4-oxo-dihydrofuran-3-yl) -ß-D-glucopyranoside) showed the following nuclear magnetic resonance spectra:
• Fig. 1 shows the (ufloomrate A: 5 ° C / min) by means of the thermogravimetric curve of the decomposition Furaneyl- obtained glucoside.
• the thermolytic cleavage of the glycosidic bond with the release of furaneol results in a theoretical mass loss of 44%.

Format, mixture and filter system corresponded to the cigarettes according to example 3. The smoke data according to ISO resulted in a dry condensate of 1.0 mg / cigarette and a smoke nicotine of 0.11 mg / cigarette at a train number of 7.1.
• the sensory evaluation of the sidestream smoke of the test samples was carried out by a trained panel of smokers and non-smokers in comparison to similar cigarettes without flavoring glycoside in the cigarette paper.
• the test samples were machine-smoked in a room of known size and defined equipment (eg 5 cigarettes in a room with a volume of 20 m).
• the evaluation was made immediately on the fresh smoke and also after 6 hours on the aged smoke.
