Definitions
- the invention relates to cigarettes containing flavor mixtures, Tobacco cartridges (fine-cut rolls) and (filter) sleeves, these Flavor mixtures on the cigarette paper or the tobacco cartridge wrapping material applied or in the pulp or cellulose pulp incorporated, to reduce by-pass smoke associated undesirable effects.
- HSR mainstream smoke
- NSR secondary flow smoke
- Cigarette smoke is naturally cigarette smoke rather than felt pleasant. There are usually exceptions to this only with smoke overlaid or aged by NSR, so-called “cold” smoke. Especially from non-smokers Properties that are perceived as uncomfortable include essentially in a "stale, bad smell” and, especially in sensitive people, in causing unwanted Irritant effects on the eyes and nose by so-called “Interfering factors” are triggered. So there are already different ones Efforts have been made to make this uncomfortable Counteracting properties. Basically you have it tries to influence the unpleasant smell with additives, what so far only with simultaneous change in taste of the HSR was possible and an adverse narrowing of the Represents degrees of freedom in cigarette design. A typical one An example of this is given in US Pat.
- the object of the invention is therefore a cigarette or cigarette tube and similarly a tobacco cartridge or tobacco cartridge wrapper to create with increased sidestream smoke acceptance, without the disadvantages of the known methods listed in Having to buy, i.e. the NSR that is forming Cigarette is said to be even after a long time pleasant tobacco, but as inconspicuous or weak as possible
- a fragrance note also be free from interference factors, i.e. not eye or irritate nose, and by no means the taste of the HSR from Change the desired tobacco aroma differently. Doing so at the same time good processability of the tobacco rod wrappings used as well as a usual burning behavior of this cigarette to be guaranteed.
- a cigarette that one with a double-layer cigarette wrapping Contains tobacco rod, the inner layer of said cigarette rod wrapping made of highly porous wrapping paper with a Air permeability of 4,000 to 60,000 CORESTA exists and the outer layer of conventional cigarette paper with an air permeability of 5-100 CORESTA, characterized in that on the inner layer of the double-layer cigarette wrapper any flavor mixture applied in encapsulated form is.
- the optional connections can be added to the above, consisting of aldehydes, heterocycles and vanillin basic aroma mixture according to the invention, individually or in Combination can be used, especially in encapsulated Form, alternatively in unencapsulated form in or on a special, double-layer cigarette wrapper, alternatively in or on a single-layer cigarette wrapper be applied.
- undesirable effects are e.g. tobacco cartridges (Fine cut rolls) or (filter) sleeves on which the invention Aroma mixtures are applied, which the at the finished cigarettes made from it their advantageous Have an effect.
- the aroma mixture preferably during the manufacturing process of the finished Cigarette applied to the cigarette rod wrapper.
- the one with a single or double layer Contained tobacco rod wrapped cigarette rod will the flavor mixture according to the invention in encapsulated or unencapsulated Mold applied directly to the cigarette rod wrapper. This is done with single-layer cigarette wrappers Application of the flavorings, either in encapsulated or unencapsulated form, directly on the used cigarette paper.
- Microcapsules from 4000 to 80,000 CORESTA, preferably 10,000 up to 50,000 CORESTA, serves in a particularly preferred form as the flavoring layer.
- the porosity of the inner Layer is after application of the capsules by brushing or similar processes to the fine mesh cellulose fiber network or highly porous paper fleece or when incorporating the capsules into the mass of fabric used to make paper, 2,000 up to 30,000 CORESTA.
- the porosity ratio to be set of the two layers of paper apply values between 1:10 to 1: 1000 ⁇ m the control of the burning behavior of the cigarette alone to guarantee the outer location.
- the porous, fine-mesh cellulose fiber network (tea bag-like Paper, highly porous wrapping paper or highly porous Paper fleece) as a carrier of the encapsulated flavors can be in one Working step, i.e. by simultaneously wrapping the tobacco stick with both papers to form the cigarette strand are processed, the porous (tea bag-like) paper or highly porous paper fleece as the inner layer of the tobacco stick wrapped and without gluing with the outer layer (cigarette paper) in the usual way on cigarette rod machines is proceeded.
- Envelope made with the two separate papers can do that Applying the microcapsules to the (tea bag-like) paper or highly porous paper fleece also immediately before production on the Cigarette machine done by placing the capsule slurry on the Paper is sprayed. Suitable devices for this are on the Market available.
- the above flavor mixture was made by brushing or spraying directly onto cigarette paper 1 (table 1, positions 1-3) applied.
- the application can be done in a separate Operation as well as directly on the cigarette machine respectively. Although part of the necessary drying process volatile flavors is lost, you get a product that when smoking a bypass smoke assessed as significantly improved supplies.
- the aroma mixture according to Example 1 is in a manner known per se converted to an oil-soluble form. To improve solubility it may make sense to use small amounts of benzyl alcohol, Use benzyl benzoate and / or triacetin.
- the aroma obtained is microencapsulated according to known methods.
- the microcapsules have a diameter of 8-30 microns, preferably 10 to 20 microns.
- For hardening the capsules e.g. Tannin ' but in no case form or glutaraldehyde.
- the melting point of these capsules is higher than 150 ° C.
- the aroma capsules by brushing or spraying on the cigarette paper brought or incorporated into the mass of fabric.
- the one with this Deliver paper (Table 1, Item 4) manufactured cigarettes when smoking a significantly improved sidestream smoke.
- the disadvantage of this application is that so-called when burning Condensate strips are created, which makes the product optically negative is affected (brown stripes in single-layer cigarette paper).
- a second disadvantage is one depending on the capsule concentration on paper significantly increased number of moves caused by the melting of the capsules as the glowing zone approaches and the associated reduction in paper porosity becomes.
- the cigarettes do not have different numbers of trains still strips of condensate.
- microcapsules from Example 2 are in a slurry.
- the capsules usually settle down.
- stable suspension is produced with the aid of a 1-5% Na alginate solution, viscosity 350-850 mPa / s, which has a uniform application of 0 5 to 50 g / m 2 in the example 4 of 30 g / m 2 ensured.
- the cigarettes made from this paper have about the same properties as in Example 3.
- microcapsules from the slurry are commonly used Drying process, usually spray drying, dried and in dry form preferably in the mass of highly porous Paper of a double-layer cigarette wrapper incorporated.
- the aroma blends incorporated in this way allow one smell-less processing and save the additional work step applying the flavor mixture to the cigarette rod wrapper. Show cigarettes made in this way same properties as those in Example 3.
- Example 1 The aroma from Example 1 is produced and encapsulated without solvent. This achieves a concentration that requires extremely small amounts of microcapsules for flavoring. This reduces the negative effects, as described in Example 2, otherwise cigarettes produced in this way achieve the same sensory results.
