Description

The present invention relates to a tobacco-containing product and to a method for producing a tobacco-containing product.

Tobacco products, such as cigarettes, cigarillos, cigars or finely cut tobacco products for home-made cigarettes, and snus products are often flavored with flavorings such as menthol, for example. Typically, such flavors provide an intense flavor and are introduced in relatively small amounts, preferably as a liquid, for example, during the preparation and seasoning of tobacco.

The disadvantage of this type of traditional flavoring is the volatility and the tendency to the loss of many flavorings.

It is also known to include at least one flavor capsule in a tobacco product that can be broken by the user in order to release the desired flavor contained in the capsule. Thus, volatile flavors can be used, but the tobacco product in question is more expensive.

The objective of the present invention is to create a tobacco-containing product that can provide the user with a new sensation of taste and aroma, but does not require large expenditures for manufacturing.

This problem is solved by a tobacco product having the characteristics specified in paragraph 1 of the claims. Claim 16 relates to a method for producing such a tobacco-containing product. Preferred embodiments of the invention are indicated in the dependent claims.

A tobacco-containing article of the invention contains tobacco and aromatic plant parts that are not derived from a tobacco plant. The amount of aromatic plant parts is in the range from 0.5 wt.% To 25 wt.% With respect to the total weight of tobacco and aromatic plant parts.

In preferred embodiments, the aromatic plant parts have a size in the range of 0.1 mm to 10 mm or in the range of 0.2 mm to 6 mm. The size of the aromatic plant parts is determined by sieving, which is further described in detail below. Briefly aromatic plant parts are processed on a series of vibrating sieves according to DIN ISO 3310-1, usually having square cells of decreasing size. If aromatic plant parts have a size in this range, virtually each of them passes through a sieve having an upper limit of the interval as the nominal cell size, while aromatic plant parts do not pass through a sieve having a lower limit of the interval as the nominal cell size. Aromatic plant parts passing the sieve can diagonally have a longer length than the nominal cell size, but they are included by definition. On the other hand, the material used for aromatic plant parts may contain some dust that even passes through the smallest cell. Said dust is by definition not considered a component of aromatic plant parts. Her contribution is usually small. For this preferred embodiment, the total size range of the aromatic plant parts is included in one of the above ranges, but may have a shorter or even much shorter extension (size distribution). All lower limits of more than 0.1 mm and all upper limits of less than 10 mm of such propagation are specifically considered here.

The amount of aromatic plant parts is provided as mass relative to the total weight of tobacco and aromatic plant parts. Therefore, any major dependence on the actual moisture content of aromatic plant parts is canceled. In the case when the amount of aromatic plant parts should be determined with high accuracy, the mass ratio should be determined after conditioning the aromatic plant parts and tobacco for 2 days (48 hours) at 22 ° C and at a relative humidity of 58-60%.

A tobacco-containing article of the invention is a flavored tobacco product in which the aromatic plant parts are natural constituents and not artificial or concentrated flavors. This provides a natural, possibly sublimated, taste sensation. The inclusion of artificial flavors, which in other cases should be introduced as alcohol extracts, is not required, which avoids alcohol components. Typically, the relative amount of aromatic plant parts is greater than the amount of a traditional concentrated aromatic substance, but not as large as to create an outstanding flavor.

Since the aromatic plant parts are relatively large, for example in the range from 0.1 mm to 10 mm or from 0.2 mm to 6 mm, they usually contain material in addition to any flavorings, for example, in the plant cell structure, which is capable of holding flavorings and reduce the effects of loss of flavoring. This may result in a slightly longer flavor life of the corresponding tobacco-containing product compared to a traditional tobacco product treated with a liquid flavor concentrate.

Due to the presence of a significant amount of aromatic plant parts in addition to tobacco, the relative amount of tobacco is less than in a traditional tobacco product. In a cigarette, cigarilla or cigar, this gives a dilution effect with respect to tobacco nicotine and other constituents, such as, for example, ammonia or nitrate. Examples are further provided below. When the pH rises due to aromatic plant parts, the taste is usually stronger, although less nicotine is present.

The aroma of sidestream smoke, such as cigarettes, can be positively modified and optimized depending on the choice of aromatic plant parts.

The appearance of aromatic plant parts, which in many applications are leaves or parts of leaves, provides a natural product and natural aroma. The tobacco product in question may give off a pleasant odor even before consumption.

In preferred embodiments of the tobacco-containing article of the invention, the aromatic plant parts comprise, for example, spiked mint, peppermint, anise, rosemary, pear, ginger, lemon myrtle, lavender, Paraguayan tea, avocado, ground coffee beans, green tea, herbs, tea or any of them mixtures. For example, peppermint or peppermint creates a pleasant aroma. A detailed (but not exclusive) list of plants giving suitable aromatic plant parts is provided further below.

In a tobacco product, at least a portion of the tobacco and aromatic plant parts may be included in the combined mixture. This means that, for example, chopped portions of tobacco and aromatic plant portions (for example, in the size range from 0.2 mm to 6 mm or from 0.1 mm to 10 mm) are mixed together to form a combined and preferably usually homogeneous mixture.

It is also possible that at least a portion of the tobacco contains reconstituted tobacco. The reconstituted tobacco sheets may be cut to form chopped reconstituted tobacco, which may be blended with aromatic plant parts, as well as natural chopped tobacco.

In addition, it is possible to obtain the reconstituted product from aromatic plant parts, for example, in a manner analogous to one of the known methods for producing reconstituted tobacco, so that at least part of the aromatic plant parts in the tobacco product contains the reconstituted product. The sheet of said recovered product can be cut to the desired size of the aromatic plant parts, for example, in the range from 0.2 mm to 6 mm or from 0.1 mm to 10 mm.

In another embodiment, a reconstituted product is used that contains a mixture of tobacco parts and aromatic plant parts. Such a reconstituted product can also be obtained similarly to traditional reconstituted tobacco. Thus, at least a portion of the tobacco and at least a portion of the aromatic plant parts are incorporated into the combined reconstituted product, which can be cut to the desired size.

In a preferred embodiment of the invention, at least part of the aromatic plant parts is provided in the form of granules, preferably in the size range from 0.2 mm to 5 mm or from 0.5 mm to 2.5 mm. Such granules can be obtained from pressed aromatic plant parts and, if required, additional water without other additives. Granules containing aromatic plant parts as well as tobacco are also possible.

In another preferred embodiment of the invention, the tobacco-containing product contains a cut sheet product with an upper load, in which the base layer contains or is made from reconstituted tobacco, and the base layer is provided on one side with aromatic plant parts. WO 03 / 082030A describes a method for producing a sheet product with a top load, in this case a top load cigarette filler, in which a base layer based on a fine fraction of tobacco and cellulosic fibers is provided on one side with a coarse tobacco fraction, the entire assembly being dried. Similarly, a base layer containing reconstituted tobacco can be provided on one side with aromatic plant parts, and after drying, this sheet product with the upper load is cut into pieces of the desired size.

It is also possible that the tobacco-containing product contains a cut sheet product with an upper load, in which the base layer contains reduced aromatic plant parts, the base layer being provided on one side with aromatic plant parts. Specified chopped sheet product with an upper load is at least part of the aromatic plant parts. It can be mixed with tobacco and / or reconstituted tobacco and, if desired, with additional aromatic plant parts.

If aromatic plant parts are included in the reconstituted leaf product, the size of the aromatic plant parts in the range of 0.1 mm to 10 mm or 0.2 mm to 6 mm should be understood as the size of the pieces of aromatic plant parts used in the method for producing the reconstituted leaf product. The recovered product is obtained, as is well known in the art.

In the case where the amount of natural aromas present in the aromatic plant parts is not sufficient to separately develop a tobacco-containing product, at least one flavor may be included in addition to the aromatic plant parts, preferably as a liquid. An example is the inclusion of menthol to achieve over-aromatization.

Typically, aromatic plant parts can have a moisture content of 5% to 35%, preferably 5% to 20%, or 7% to 12% with respect to the total dry weight of the respective aromatic plant parts plus moisture. After mixing with tobacco, moisture is usually balanced between aromatic plant parts and tobacco, for example in sealed containers. A cigarette usually has a moisture content of 7% to 14%. Snus typically has a moisture content of about 35%.

With regard to tobacco in a tobacco product, all types of traditional tobacco and tobacco blends may be used, if required, including reconstituted tobacco. Examples are the American blend and the Virginia blend.

The tobacco-containing article of the invention is provided as a cigarette, for example, as a fully flavored cigarette having a tar level depending on the regulation of the limit level, as a light cigarette having a tar level of up to 7 mg, or as an ultra-light cigarette having a tar level of up to 2 mg, or as cigarilla or like a cigar. In such embodiments, tobacco and aromatic plant parts are contained in the core of a cigarette, cigarilla or cigar, respectively. This does not exclude, however, that the filter also contains tobacco and / or aromatic plant parts.

In various embodiments of the invention, the tobacco-containing product is provided in the form of pipe tobacco or in the form of fine cuts for home-made cigarettes packaged in a suitable shell. Home-made cigarettes are known as “self-rolled cigarettes” (RYOs), which means that the user takes a piece of small cut containing tobacco and aromatic plant parts from the package, puts it into cigarette paper (if required with an additional filter), rolls the cigarette paper around the small cut and glues a seam of small cuts. Another type of home-made cigarettes is “homemade” (MYO), when small cuts are taken from the packaging and poured into a specific device, which, when the user is working, automatically or semi-automatically forms the finished smoking article.

If the tobacco-containing article is provided as a cigarette, cigarilla or cigar and contains a core, such as a cigarette core, the core (which contains tobacco and aromatic plant parts) may be wrapped with low side-stream cigarette paper having a bulk in the range of 35 g / m ² to 60 g / m ² having a porosity of less than 15 units. Coresta (15 ml / (cm ² · min · kPa)) and containing filler. The filler contains at least 30% CaCO ₃ and / or at least 30% MgO and / or at least 3% Mg (OH) ₂ , the percentage being expressed in wt% of the corresponding compound in relation to the total weight of cigarette paper with a low side stream.

A tobacco-containing product may also be provided in the form of “snus”, a product consumed by placing it on the cheek for a period of time. Preferably, snus containing tobacco and aromatic plant parts is obtained in ground and sieved form. Snus particles can have a size range, for example, from 0.1 mm to 1.5 mm or from 0.1 mm to 0.8 mm.

In many applications, including the options already described above, the tobacco-containing article contains chopped tobacco and / or chopped leaf products. Typically, the cutting width of the tobacco or the corresponding sheet product may be the width of the cut tobacco in traditional tobacco products, for example, 0.2-0.75 mm for fine cut tobacco, more than 1.5 mm for pipe tobacco, or 0.6-0.9 mm for regular cigarettes. Such a width may also be suitable for aromatic plant parts when used in the form of chopped leaves or in the form of chopped leaves.

In a preferred method for producing a tobacco-containing product according to the invention, after cutting the tobacco, aromatic plant parts that are not obtained from a tobacco plant and which have a size in the desired range, for example, in the range of 0.1 mm to 10 mm or in the range of 0.2 mm to 6 mm are introduced into tobacco in an amount in the range from 0.5 wt.% To 25 wt.% With respect to the total weight of tobacco and aromatic plant parts. This means that tobacco, or at least part of the tobacco, is cut independently of the aromatic plant parts. It is usually possible that uncut large aromatic plant parts are already included in the tobacco parts, for example leaves, veins, stems, or in the reconstituted tobacco sheet before the cutting step is carried out. Preferably, however, aromatic plant parts are introduced into the process relatively later, as they can release strong aroma, which tends to contaminate processing equipment.

For example, aromatic plant parts (preferably chopped) can be included in the processing of chopped tobacco, for example, in a mixing or flavoring process.

The invention is further described in more detail with the aid of examples.

Sieving method

In order to determine reproducible sizes of aromatic plant parts, the sieving method is used. This method is carried out by analogy with DIN V 10376 of February 2005 ("Analysis of tobacco and tobacco products. Determination of the size of the fillers of cigars and cigarillos using sieve analysis").

For this purpose, the studied aromatic plant parts are moisture-conditioned at a relative humidity of (70 ± 2)% and at a temperature of (22 ± 1) ° C for 48 hours. If the particles are too dry, they are destroyed during sieving, which gives erroneous results.

Moisture-conditioned aromatic plant parts are processed on a set of vibrating screens according to DIN ISO 3310-1, with cells of decreasing size. If aromatic plant parts have a size distribution in a given interval, in fact each of them will pass a sieve having an upper limit of the interval as the nominal cell size, while aromatic plant parts will not pass a sieve having a lower limit of the interval as the nominal cell size. Individual aromatic plant parts passing diagonally through the sieve may be longer than the nominal cell size, but they are included by definition. On the other hand, the material used for aromatic plant parts may contain some dust that even passes through the smallest cell. Said dust is by definition not considered a component of aromatic plant parts. Her contribution is usually small.

Other details of the method follow from DIN ISO 10376. As already indicated, this sieving method is carried out similarly with the following differences.

For sowing leaves, the scattering installation carries out horizontal vibrations of 15 mm with a frequency of 270 per minute for 5 minutes (instead of 10 minutes). The mesh sizes are 1.18 mm, 2.36 mm and 4 mm. For sieving granules, the dispersion unit operates for 1 min and the mesh sizes are 1.6 mm, 1.4 mm, 1.2 mm, 1.0 mm, 0.8 mm, 0.5 mm, 0.25 mm and 0 mm

If the size distribution is to be determined with high accuracy, a set of several screens can be used. In the case where the number of sieves exceeds the capacity of the diffuser, the size distribution can be determined sequentially.

Examples of aromatic plant parts

Typically, a large number of plant particles can be used as sources of aromatic plant parts according to the invention. Spike mint, peppermint, anise, rosemary, pear, ginger, lemon myrtle, lavender, Paraguayan tea, avocado, ground coffee beans, green tea, as well as herbs and tea in general terms have already been mentioned above. Depending on the plant particles, aromatic plant parts can be obtained from leaves, flowers, fruits, roots, bark, etc. Mixtures of aromatic plant parts from various particles are also possible.

The following table 1 presents a variety of plant particles, which can be, in particular, used for the purposes of the present invention.

Example 1

Spearmint

Mint (Menta spicata) contains partially (but not much) menthol, as well as carvone, bulletin, limonene and esters.

After conditioning at 22 ° C and 60% relative humidity, a sample of spiked mint leaves has a relative humidity of 10.0%. Hereinafter, all contents of relative humidity refer to the sum of dry mass (determined after processing in an oven at 82 ° C for 3 hours; “Horo” method) and moisture.

From this sample, a mixture is obtained with an American tobacco mixture, which contains 10 wt.% Spiked mint leaves and 90 wt.% Tobacco. After conditioning at 30 ° C and 75% relative humidity, the mixture has a relative humidity of 18.5%. Under the same conditioning conditions, pure tobacco has a relative humidity of 19.1%, and a sample of pure spike mint has a relative humidity of 13.7%.

The size distribution of the leaves of two different specimens of spiky mint leaves is determined using the sieving method described above using mesh sizes of 1.18 mm, 2.36 mm and 4 mm. In the first sample, about 2.6 wt.% Of the leaves does not pass through a 4 mm mesh sieve, about 27.3 wt.% Does not pass through a 2.36 mm sieve, about 57.2 wt.% Does not pass through a 1.18 sieve mm mesh and about 12.9 wt.% passes through a 1.18 mm mesh sieve, the peak size being slightly more than 1.18 mm. In the second sample, the corresponding values are 10.2%, 63.1%, 24.8% and 2.0%, respectively, and there is a peak at a sheet size of about 2 mm.

Example 2

Peppermint

Peppermint (Menta piperita) contains menthol, menton, cineole, tannins and flavonoids.

A sample of granulated peppermint after conditioning at 22 ° C and 60% relative humidity has a relative humidity of 8.6%.

The size distribution of the granules of this sample is determined using the sieving method described above. Table 2 presents the fraction of the entire sample of 402.34 g, retained by a sieve of a given cell size (mesh sizes 1.6 mm, 1.4 mm, 1.2 mm, 1.0 mm, 0.8 mm, 0.5 mm, 0.25 mm and 0 mm).

table 2 Size distribution in a sample of granulated peppermint Mesh size (mm) Retained Mass (g) Fraction (%) 1,6 0.05 0.01 1.4 0.35 0.09 1,2 19.79 4.92 1,0 67.75 16.84 0.8 98.50 24.48 0.5 163.15 40.55 0.25 51,20 12.73 0 1.55 0.39 402.34 100.00

The data presented in table 2 show that essentially each of the granules has a size in the range from 0.25 mm to 1.2 mm. The contribution of particles passing 0.25 mm mesh (dust) is negligible. The distribution has a peak at about 0.5 mm.

Example 3

Spiked mint, peppermint

In Example 3, two other samples of spiked mint and peppermint are examined. In both samples, aromatic plant parts are granular in shape. After conditioning at 22 ° C and 60% relative humidity, an ear of spearmint has a relative humidity of 7.5%, and a sample of peppermint has an 8.5% relative humidity.

The granule size distribution obtained as described above is shown in Table 3.

Table 3 Size distribution in the sample of granulated spike mint and in the sample of granulated peppermint Mesh size (mm) Spike mint fraction (%) Peppermint fraction (%) 1,6 0.04 0.02 1.4 0.02 0.08 1,2 0.12 0.28 1,0 10.00 15,56 0.8 43.78 39.94 0.5 43.69 41.06 0.25 2,31 3.04 0 0.04 0.04 100.00 100.00

In both samples, the granules essentially have sizes in the range of 0.25 mm to 1.2 mm with peaks between 0.5 mm and 0.8 mm.

Example 4

A mixture of tobacco and peppermint

In Example 4, one of the samples of the peppermint of Example 1 (a sample with a peak size of about 2 mm) is used to obtain substantially homogeneous mixtures of peppermint leaves and American tobacco blend. Of the mixtures containing 2% by weight, 5% by weight, 10% by weight and 20% by weight of peppermint (relative to the total weight of peppermint and tobacco, designated as MS1, MS2, MS3 and MS4, respectively), cigarettes are obtained with a filter with a diameter of 7.8 mm with a cellulose acetate filter plug 21 mm long and a tobacco-mint spike 62 mm long. Some components of the mixtures of tobacco / mint are analyzed. In addition, cigarette properties are determined, including smoke data (according to DIN ISO 4387 / A). The results for samples MS1, MS2, MS3 and MS4, as well as for the control sample CS (American Tobacco Mixture without Spike Peppermint) are summarized in Table 4. The abbreviations used in Table 4 are explained at the end of Table 5 below.

From the data of table 4 it can be seen that tobacco nicotine (i.e., the relative amount of nicotine in the mixture of tobacco and peppermint) decreases with an increase in the amount of peppermint in the mixture. There is also a tendency that nicotine smoke also decreases when the contribution of spiked mint increases.

In addition, with an increase in the quantity of spearmint, the hardness of the cigarette decreases to some extent (not shown in table 4).

Example 5

A mixture of tobacco and black tea

In Example 5, a substantially homogeneous mixture of American tobacco blend and black tea (loose leaves) is obtained. From mixtures containing 2 wt.%, 5 wt.%, 10 wt.% And 20 wt.% Black tea (relative to the total mass of black tea and tobacco, designated as TS1, TS2, TS3 and TS4, respectively), cigarettes are obtained with a filter with a diameter of 7.8 mm with a cellulose acetate filter plug 21 mm long and a tobacco / black tea stem 62 mm long. Some components of tobacco / black tea blends are analyzed. In addition, cigarette properties are determined, including smoke data (according to DIN ISO 4387 / A). The results for samples TS1, TS2, TS3 and TS4, as well as for the control sample CS (American tobacco blend without black tea) are summarized in Table 5. The abbreviations used in Table 5 are explained at the end of the table.

Table 5 shows that the amount of tobacco nicotine (i.e., the relative amount of nicotine in the mixture of tobacco and black tea) decreases with increasing amount of black tea in the mixture.

Example 6

Storage Characteristics

Explore the relative loss of flavor components from filter cigarettes obtained from mixtures of American tobacco mixture and colobra mint in accordance with example 4. To this end, boxes of cigarettes containing cigarettes containing mixtures of MS1 and MS2 are stored for six months under various conditions, t i.e., as a closed box in a refrigerator, as a closed box at room temperature, and as an open box at room temperature. The components of the aroma of peppermint are determined by gas chromatography before and after six months of storage.

Table 6 presents for both mixtures MS1 and MS2 the average values of the absolute amounts of the constituents of the aroma of spearmint before storage and the relative losses (relative to the initial quantities) after six months of storage.

The results presented in table 6 show the following trends: the relative losses of the components of the spike mint from the closed boxes stored at room temperature and from the closed boxes stored in the refrigerator are similar. In the case of open packages stored at room temperature, the relative losses are significantly higher. For cigarettes with a large contribution of peppermint, the relative loss tends to be somewhat higher. In addition, the migration of spike mint constituents during the storage period gives some accumulation of aroma in cigarette filters (data not shown in table 6).

Example 7

Mixtures of tobacco and lemon myrtle

In Example 7, lemon myrtle (Backhousia citriodora) is used to produce substantially homogeneous blends of lemon myrtle leaves and American tobacco blend. Of the mixtures containing 2 wt.%, 5 wt.%, 10 wt.% And 20 wt.% Lemon myrtle (relative to the total weight of lemon myrtle and tobacco), designated as LM1, LM2, LM3 and LM4, respectively, receive cigarettes with a filter with a diameter of 7.8 mm with a cellulose acetate filter plug 25 mm long and a tobacco / lemon myrtle stem 58 mm long. Some constituents of tobacco / lemon myrtle mixtures are analyzed. In addition, cigarette properties are determined, including smoke data (according to DIN ISO 4387 / A). The results for samples LM1, LM2, LM3 and LM4, as well as for the control sample CS (American tobacco blend without black tea) are summarized in table 7. The abbreviations used in table 7 are explained at the end of table 7.

From the data of table 7 it is seen that the amount of tobacco nicotine (i.e., the relative amount of nicotine in the mixture of tobacco and lemon myrtle) decreases with increasing amount of lemon myrtle in the mixture. No reduction in nicotine smoke was observed.

A mixture of tobacco and ginger

In Example 8, ginger (Zingiber officinale) is used to produce substantially homogeneous mixtures of dried particles of ginger rhizome and American tobacco blend. From mixtures containing 2 wt.%, 5 wt.% And 10 wt.% Ginger (relative to the total weight of ginger and tobacco), designated as G1, G2 and G3, respectively, receive cigarettes with a filter diameter of 7.9 mm cellulose acetate 27 mm filter plug and 56 mm tobacco / ginger stem. Some components of the tobacco / ginger blends are analyzed. In addition, cigarette properties are determined, including smoke data (according to DIN ISO 4387 / A). The results for samples G1, G2 and G3, as well as for the control sample CS (American tobacco blend without black tea) are summarized in table 8. The abbreviations used in table 8 are explained at the end of table 7 above.

From the data of table 8 it is seen that the amount of tobacco nicotine (i.e., the relative amount of nicotine in the mixture of tobacco and ginger) decreases with increasing amount of ginger in the mixture. No reduction in nicotine smoke was observed.

Example 9

Mixtures of tobacco and lavender

Cigarettes containing 2% by weight and 5% by weight of lavender flowers (Lavandula officinale) (relative to the total weight of lavender and tobacco) are prepared in accordance with Example 4. The cigarettes are smoked using a test bench to evaluate their taste. Whereas it was determined that a sample with 2 wt.% Lavender tastes slightly soapy and perfume-like, the taste of lavender was clearly identified in the 5% sample.

Both options were also smoked by a machine in a stainless steel experimental chamber. After smoking, the air in the closed chamber was thoroughly mixed by fans. A sequential odor test bench is used to evaluate smoke in a chamber using a standard questionnaire. It was found that the smoke intensity remains unchanged compared to a standard cigarette, while the smell of smoke for a sample with 2 wt.% Lavender was rated as less intense and more pleasant. A similar effect is noted for the 5% sample, but in contrast to the 2% sample, the smell of lavender also differs.

Example 10

Tobacco / Lavender with Low Sideflow Paper

Cigarettes containing 2% by weight and 5% by weight of lavender flowers (relative to the total weight of lavender and tobacco) are prepared according to Examples 4 and 5, but cigarette paper with a low side stream (LSS) is used instead of traditional cigarette paper. The paper has a porosity of 6 units. Koresta, the bulk is 45 g / m ² and the filler content is 45% calcite. 1 unit Coresta = 1 ml / (cm ² · min · kPa).

The smell of smoke in the experimental chamber is evaluated as in example 9. Using the stand it was found that not only the intensity is reduced compared to a traditional cigarette, but also the smell of smoke is more pleasant and less annoying.
