This document relates generally to providing oral tobacco enjoyment through the use of a smokeless pressed tobacco product containing a tobacco component.

Smokeless tobacco products, such as chewing tobacco and snuff, contain an insoluble residual component in amounts that typically require disposal. More recently, other forms of smokeless tobacco products have appeared on the market or been described, including products in the form of gels, wafers and tablets.

The production of a smokeless tobacco product in compressed form, such as tablets, is a very difficult task. Generally, tablets can be classified as molded tablets or compressed tablets, and each of these types is usually manufactured in a different way. Molded tablets can be made by introducing an impurity such as a filler or a binder to form a mixture, adding a solvent such as water, ethyl alcohol and the like to the mixture to obtain a hydrated powder, and forming this hydrated powder to provide a predetermined form by forming.

There are two methods of forming the moistened powder into tablets, according to one of which, the moistened powder is pressed into a mold with an external force, which has a certain shape, and according to the other, the moistened powder is given a plate-like shape on a rolling machine, and a stamp of a certain size is pressed against this plate forms for cutting. It is clear that it can be difficult to work with a wet one. powder during manufacture, as wetted powder tends to stick to surfaces when ejected from the mold, potentially causing changes in product mass. In addition, it may cause surface contamination or the product may be damaged, as its mechanical strength is reduced.

Compressed tablets can be formed from dry powder under relatively high pressure. Under the action of the force applied to the material, the powder granules are compressed and immediately formed into a tablet.

Compressed tablets are more suitable for mass production and can outperform molded tablets in terms of accuracy and quality, but because the dry powder is compressed under high pressure, the compressed product can potentially be inferior in dissolution and disintegration ability. These considerations may be particularly important in finding a form of pressed tobacco product capable of providing tobacco satisfaction.

For example, when working with tobacco, moisture content can become important and will need to be controlled throughout the process.

Thus, there remains a need for a dissolvable smokeless tobacco product that provides the pleasure of smoking.

This document describes a dissolvable pressed tobacco product for use in the oral cavity, as well as methods of manufacturing pressed tobacco products.

The use of maltodextrin as a binding agent has several advantages when used in the pressed tobacco products described herein. Maltodextrin improves product texture, increases product hardness and provides better mouthfeel for consumers. It is also a good granulating admixture. Maltodextrin is a moderately sweet polysaccharide that is often used as an additive to food products. It is made from starch, usually in the form of a creamy white hygroscopic powder. Maltodextrin is easily digestible and is absorbed as quickly as glucose. Maltodextrin can be obtained from any starch. In SILA, the starch is usually corn or potato, while in other regions (e.g. Europe) it is usually wheat.

Lubricants can be auxiliaries in the manufacture of a pressed tobacco product that reduce or prevent sticking to dies and molds during extrusion of the pressed tobacco product composition. Sticking during extrusion can be a problem if the composition containing the tobacco component is compressed into tablets as a dry blend. This difficulty can be overcome by using insoluble lubricants such as magnesium stearate, calcium stearate or their derivatives.

Flavoring may be added in an amount sufficient to provide the desired flavoring, for example, from about 195 (wt.) to about 1595 (wt.) or from about 395 (wt.) to about 695 (wt.).

In another embodiment of the present invention, the amount of tobacco is approximately 4095 (w/w) to provide the desired tobacco flavor.

In another embodiment of the present invention, the tobacco component includes crushed or powdered tobacco and optionally tobacco extract. The tobacco component may include its own tobacco flavorings (flavor enhancers), but in a preferred embodiment, the flavorings are added separately as one or more separate components of the composition.

Pressed tobacco products can be made by direct pressing or granulation. Using both of these processes, a pressed tobacco product is obtained, which, in an alternative embodiment of the present invention, can be further processed with a coating that can contain cellulose-based polymers, dyes, flavorings, etc.

The technological process of manufacturing pressed tobacco products by direct pressing includes the operation of preparing and processing a dry tobacco mixture, one or more mixing operations and a pressing operation. In one of the variants of the implementation of the present invention, the operation of impregnation with lipids is also applied. In an alternative embodiment of the present invention, the pressed tobacco product is subjected to additional processing and coating in two operations (coating operation and drying operation).

The operation of preparation and processing of the tobacco mixture can be carried out as follows. First, the tobacco mixture is prepared. As indicated above, the tobacco may include a blend of such as Bright, Burley, Dark Shade Cured Tobacco, and Oriental-type tobaccos, or one of the aforementioned tobaccos may be used instead of the blend. Tobacco can be dried or not dried; however, dried tobacco is preferred. The tobacco component may contain tobacco leaf blades and/or veins, and may also contain crushed modified veins.

After that, the tobacco mixture is subjected to additional processing using a grinding operation.

The ground tobacco may have an average particle size of less than about 1 mm, or less than about 0.5 mm, or less than about 0.1 mm. In one embodiment of the present invention, the average particle size may be greater than about 100 nm or greater than about 1 μm. In another embodiment of the present invention, the average particle size may be between about 1 micron and 0.1 mm, for example, 400 mesh tobacco dust in which 9,595 particles pass through a standard mesh of 400 wires per square inch, (approximately 400 wires per 6, 45 square centimeters).

After the grinding operation, the tobacco component can undergo heat treatment (semi-pasteurization) in any suitable way. For example, the tobacco component can be subjected to heat treatment using high pressure and/or temperature and steam. In one of the variants of the present invention, the heat treatment operation is performed at a temperature of from about 1702E to about 1902E (from about 77"C to about 882C) for a period of time from about 1 hour to about 2 hours. Other methods of heat treatment can also be used. After heat treatment, the tobacco component can be stored at or near room temperature for a desired period of time.In one embodiment of the present invention, lipid impregnation is achieved by preparing a mixture comprising powdered tobacco leaf laminae and at least one lipid prior to the heat treatment operation. , and further heat treatment of the mixture of powdered tobacco leaf plates and at least one lipid. Before the heat treatment operation, an optional admixture can be added to the mixture to adjust the pH. The heat treated mixture can then be used in the original composition of compone nts described below in this document.

In one of the embodiments of the present invention, the tobacco component is mixed in a dry state with the original composition of components, which include at least one binding filler, at least one flavoring agent, at least one lubricant and at least one lubricant. In another embodiment of the present invention, at least one binder filler such as microcrystalline cellulose or other material described hereinabove, a moisture absorbent such as silicon dioxide or fumed colloidal silica, a glidant such as fumed colloidal silica, and at least one the flavoring is added to the starting composition in the first mixing operation, and at least one lubricant is added to the composition in the second mixing operation.

Fumed colloidal silica is added to the pressed tobacco product in an amount sufficient to provide from about 0.195 to about 595, or from about 0.295 to about 295, or from about 0.2595 to about 0.595 dry weight of the pressed tobacco product.

Optionally, after mixing, the resulting composition can be ground using known methods and equipment. In alternative embodiments of the present invention, the composition is comminuted using a 20 mesh or 30 mesh screen using commercially available comminution equipment, such as, for example, an OtsadgooF or Sotikyu manufactured by Oshtsadgoo Epdipeegipud, Millburn, IN

New Jersey, USA.

After receiving the finished composition, it is pressed or compressed using a tablet press. In Fig. 2 schematically shows an example of a tableting press 100. The cell 106 of the mold is made in the mold 104 attached to the table 102 of the mold. The lower punch 112 is located in the lower section 114 below the mold hole 106. The lower punch 112 can be adjusted so that the volume in the mold hole 106 is adjusted to a predetermined volume for making pressed tobacco products 10 (shown in Fig. 1) of the desired size and mass. In one embodiment of the present invention, the pressed tobacco product has a mass of from about 200 mg to about 500 mg. In another embodiment of the present invention, the pressed tobacco product has a mass of approximately 300 mg.

The composition for making a pressed tobacco product can be fed through the feed tube 118 located inside the mold hole 106 and compressed by the upper punch 108 located in the upper section 110 to form the pressed tobacco product 10. After pressing, the pressed tobacco product 10 is pushed out by the lower punch 112 , so that the pressed tobacco product 10 is removed from the hole 106 of the mold. The pressing force provided by the pusher 116 can be from about 1 kN/punch to about 100 kN/punch, or from about 5 kN/punch to about 90 kN/punch, or from about 8 kN/punch to about 80 kN/punch .

The inner diameter of the mold is usually from about 3 mm to about 20 mm, or from about 3 mm to about 13 mm, or from about 4 mm to about 10 mm. The lid 106 of the mold 104 can be given a round, oval, elongated, annular, cylindrical, triangular shape, etc. The upper or lower surface of the pressed tobacco product 10 may be embossed or flat embossed with symbols or letters, or may be given any other acceptable form as understood by those skilled in the art.

Although an example tablet press 100 is shown with a single die-punch pair, there are many alternative means of performing the pressing operations, and this description should not be construed as limiting the use of any particular equipment. In another embodiment of the present invention, the pressing operation is performed using a rotary tablet press (not shown). A rotary tabletting machine has a rotating plate with several molds designed to form a tablet pressed tobacco product. As in the embodiment of the present invention shown in Fig. 2, the composition for the production of a pressed tobacco product is introduced into a mold, after which it is subjected to pressing.

The precompression and pressing forces can be selected based on the type and model of the press, the physical properties that are desired for the pressed tobacco product (eg, desired hardness, brittleness, loosening or dissolving characteristics, etc.), the desired appearance and size of the pressed tobacco product, etc. . As indicated, the pressing force may be from about 1 kN/punch to about 100 kN/punch, or from about 5 kN/punch to about 90 kN/punch, or from about 8 kN/punch to about 80 kN/punch. The pressed tobacco product 10 produced by pressing may have a hardness of from about 20 N to about 200 N, or from about 50 N to about 150 N. In other embodiments of the present invention, the tablet may dissolve in the oral cavity for at least about 30 min, or at least about 15 min, or at least 10 min.

In one of the embodiments of the present invention, after the pressing operation, the pressed tobacco product can be placed in an oil bath with a hot lipid mixture. Hot liquid lipids fill the interparticle spaces of the tablet, extracting oil-soluble materials from the tobacco matrix and incorporating them into the lipid. In this way, the lipid seeps or penetrates into the pressed tobacco matrix with the hot lipid mixture. The oil bath is maintained at a temperature of from about 40227 to about 802, or from about 5020 to about 702, or from about 552 to about 6520. The pressed tobacco product is left in the oil bath for a time of from about 5 minutes to about 25 minutes, or from about 10 min to about 20 min to achieve the proper level of lipid impregnation. The temperature of the oil bath and the length of time the pressed tobacco product is in the oil bath also depends in part on the slip point of the lipid used. Placement in the oil bath may be done by immersion as such or may also be done by spray coating in a rotary coating machine or by using vacuum or pressurized chambers. Coating may be accompanied by inert gas purging to eliminate the possibility of lipid oxidation if essentially unsaturated oils are used.

After the impregnation operation, the pressed tobacco product is subjected to a heating operation to ensure an even distribution of the molten lipids in the interparticle spaces of the tablet due to capillarity. Heating can be done in many ways. In one embodiment of the invention, the heating operation is carried out in a furnace at a temperature of from about 302 to about 702, or from about 402; to about 60°C, or from about 45°C to about 5520. The pressed tobacco product is held in the oven for from about 5 min to about 25 min, or from about 10 min to about 20 min to achieve a low moisture level (less than about 595) After performing the heating operation in the oven, the pressed tobacco product is kept for cooling.

When cooled in this way, the lipid mixture does not penetrate very deeply and instead forms an attractive thin and smooth coating on the surface of the tobacco matrix.

In another embodiment of the present invention, heating is carried out by using a fluidized bed dryer. During fluidized bed drying, a stream of heated air is fed into the bottom of a product container filled with pressed tobacco products. Thrust is created with the help of a fan, and fresh air is sucked into the installation. This flow of hot air pushes the products away from each other at a certain speed, creating turbulence among the products. This phenomenon is known as fluidization and causes hot air to stir the pressed tobacco products. Heat transfer is relatively high and uniform. A fluidized bed dryer is available from Vidani Rpapta Maspipegu Gityei, Maharashtra, India and other suppliers. After the drying operation in the fluidized bed, the pressed tobacco product is kept for cooling. After cooling, the lipid mixture subjected to this treatment also forms an attractive thin and smooth coating on the surface of the tobacco matrix.

After cooling the tablet and solidifying the lipids, the dissolved materials remain with the already solid lipid until the pressed tobacco product is placed in the mouth. While in the mouth, the lipids melt, allowing the dissolved flavorings to escape from the pressed tobacco product, which are still in the liquid lipid that coats the tongue and oral mucosa, providing a pleasant, soft mouthfeel. The hydrophobic lipid also inhibits the migration of saliva into the tablet, providing gradual dissolution and reducing chipping of the tobacco matrix, which causes the formation of the "muddy" texture of the known pressed tobacco product. In addition, many flavors and fragrances are hydrophobic, so they are difficult to release from the known pressed tobacco product using only aqueous dissolution in saliva. Instead, the oils allow these flavorings and odorants to freely diffuse within the oral cavity and retronasal olfactory cavity. Hydrophobic aromatic oils can be added directly to the impregnation lipid mixture or sprayed after impregnation.

In embodiments of the present invention, lipid matrices can be added after pressing as a simple coating using a heating machine for coating, by spraying or cascade glazing. Tobacco solids, flavorings, or a combination thereof may be added to the coating lipids to form an orodispersible tobacco-flavored coating. The lipid coating may be coated with a thin, fast-dissolving material, such as sugars, soluble starches, or combinations thereof, to protect the lipid coating from melting at high storage temperatures.

The operations used in the production of the pressed tobacco product by granulation include a mixing operation, a granulating operation, a drying operation, an optional mixing operation, and a pressing operation. Other optional operations may be applied, such as the operation of impregnation with at least one lipid, as described above in this document. In another embodiment of the present invention, the pressed tobacco product is subjected to additional processing and coating in two operations (coating operation and drying operation).

In the production process of granulation, the tobacco mixture is first prepared. As stated above, the tobacco may include a blend of two or more tobaccos, such as Bright, Burley, and Oriental-type tobaccos, or one of the aforementioned tobaccos may be used instead of the blend. Tobacco can be cured or uncured, but dried tobacco is preferred. The tobacco component may contain tobacco leaf blades, veins, or a combination thereof.

After that, the tobacco mixture is subjected to additional processing using a grinding operation.

The ground tobacco may have an average particle size of less than about 1 mm, or less than about 0.5 mm, or less than about 0.1 mm:. In one embodiment of the present invention, the average particle size may be greater than about 100 nm or greater than about 1 μm. In another embodiment of the present invention, the average particle size may be between about 1 micron and 0.1 mm, for example, 400 mesh tobacco dust in which 9,595 particles pass through a standard mesh of 400 wires per square inch, (approximately 400 wires per 6, 45 square centimeters).

After the grinding operation, the initial mixture is subjected to granulation. The granulation mixture may be formed by mixing the tobacco components with a suitable liquid in a container such as a mixing tank. In a preferred embodiment, the liquid is water, although a mixture of liquids such as water and alcohol (ethanol) may be used. In those embodiments in which the tobacco component contains crushed or powdered tobacco, some compounds from the tobacco may pass into the solution. In one of the variants of the implementation of the present invention, the mixing tank has a temperature controller. The aqueous solution may also contain at least about 0.595 of the cellulose-based polymer. The described mixing process is usually called wet granulation. Those skilled in the art know that granulation is commonly defined as a size-enhancing process in which small particles are combined into larger, permanent aggregates in which the primary particles can still be distinguished. Wet granulation is a variant of this process and refers to granulation in which solvents and binders are added during the sizing process. For additional information, see Girr5 (1993) U. Rpapt. 5 83:937-947; or OIto (1998) Ogpia Oeu.

Ipa. Rpagt. 24:771-778.

A variety of devices for such mixing, or stirring, or granulation, are well known.

For example, the granulation can be carried out in a fluidized bed granulator, such as a granulator manufactured by Sai Aig Tesppidnez Ips., Ramsey, New Jersey, USA.

The temperature during granulation can be adjusted to any value as long as it does not exceed the melting point of any components of the composition and a balance between spraying and drying is maintained. In one embodiment of the present invention, the temperature during granulation and drying is relatively low, i.e. in the range from about 2027 to about 5020. The resulting composition after granulation is dried to a temperature of 409С before forming a pressed tobacco product.

After that, the tobacco can undergo heat treatment using any suitable method.

For example, the tobacco component may be pasteurized using high pressure and/or temperature and steam. In one embodiment of the present invention, the heat treatment operation is performed at a temperature of from about 1702E to about 1902E (from about 772 to about 882) for a period of time from about 1 hour to about 2 hours. Other pasteurization methods may also be used. After heat treatment, the tobacco component can be stored at or near room temperature for a desired period of time. In one of the variants of implementation of the present invention, impregnation with lipids is achieved by preparing a mixture containing powdered tobacco leaf plates and at least one lipid, before the heat treatment operation, and further heat treatment of the mixture of powdered tobacco leaf plates and at least one lipid. Before the heat treatment operation, an optional admixture can be added to the mixture to adjust the pH. The heat-treated mixture can then be used in the original composition of the components described below in this document.

After the granulation operation, the tobacco component is mixed in a dry state with the original composition of components, which include at least one binding filler, at least one flavoring agent, at least one lubricant and at least one lubricant. In another embodiment of the present invention, at least one binder, such as microcrystalline cellulose or other material described hereinabove, a glidant, such as fumed colloidal silica, and at least one flavor are added to the starting composition in the first mixing step, and at least one lubricant is added to the composition in the second mixing operation. The amount of fumed colloidal silica added to the pressed tobacco product is sufficient to provide from about 0.195 to about 595, or from about 0.295 to about 295, or from about 0.2595 to about 0.595, by dry weight of the pressed tobacco product.

Optionally, after mixing, the resulting composition can be ground using known methods and equipment. In alternative embodiments of the present invention, the composition may be comminuted using a 20-mesh or 30-mesh screen using commercially available comminution equipment such as, for example, a COsadgaF or a SoticF) manufactured by Otsaidga Epdipegipd, Millburn, New Jersey. USA.

After receiving the finished composition, it is pressed or compressed again using a tablet press of the type 100 shown in Fig. 2. As shown in Fig. 2, the mold hole 106 is also made in the mold 104 attached to the mold table 102. The lower punch 112 is located in the lower section 114 below the hole 106 of the mold. The lower punch 112 can be adjusted so that the volume of the cavity in the cell 106 of the mold is adjusted to a predetermined volume for the production of pressed tobacco products 10 (shown in Fig. 1) of the desired size and weight. In one embodiment of the present invention, the pressed tobacco product has a mass of from about 200 mg to about 500 mg.

In another embodiment of the present invention, the pressed tobacco product has a mass of approximately 300 mg.

The composition for making a pressed tobacco product can be fed through the feed tube 118, placed inside the hole 106 of the mold and compressed by the upper punch 108 located in the upper section 110 to form the pressed tobacco product 10. After pressing, the pressed tobacco product is pushed out by the lower punch 112, so that the pressed tobacco product 10 is removed from the hole 106 of the mold. The pressing force provided by the pusher 116 can be from about 1 kN/punch to about 100 kN/punch, or from about 5 kN/punch to about 90 kN/punch, or from about 8 kN/punch to about 80 kN/punch .

The inner diameter of the mold is usually from about 3 mm to about 20 mm, or from about 3 mm to about 13 mm, or from about 4 mm to about 10 mm. The lid 106 of the mold 104 can be given a round, oval, elongated, annular, cylindrical, triangular shape, etc. The upper or lower surface of the pressed tobacco product 10 may be embossed or flat embossed with symbols or letters, or may be given any other acceptable form.

Although an example tablet press 100 is shown with a single die-punch pair, there are many alternative means of performing the pressing operations, and this description should not be construed as limiting the use of any particular equipment. In another embodiment of the present invention, the pressing operation is performed using a rotary tablet press (not shown). A rotary tabletting machine has a rotating plate with several molds designed to form a tablet pressed tobacco product.

Pressing effort may be selected based on the type and model of the press, the physical properties desired for the pressed tobacco product (eg, desired hardness, brittleness, fluffing or solubility characteristics, etc.), desired appearance and size of the pressed tobacco product, etc. As indicated, the pressing force can be from about 1 kN/punch to about 100 kN/punch, or from about 5 kN/punch to about 90 kN/punch, or from about 8 kN/punch to about 80 kN/punch. The pressed tobacco product 10 produced by pressing may have a hardness of from about 20 N to about 200 N, or from about 50 N to about 150 N. In other embodiments of the present invention, the tablet may dissolve in the oral cavity for at least about 30 min, or at least about 15 min, or at least 10 min.

As described above in this document, after the pressing operation, the pressed tobacco product can be placed in an oil bath with a hot lipid mixture. Hot liquid lipids fill the interparticle spaces of the tablet, extracting oil-soluble materials from the tobacco matrix and incorporating them into the lipid. In this way, the lipid seeps or penetrates into the pressed matrix of the tobacco product with the hot lipid mixture. The oil bath is maintained at a temperature of from about 4027 to about 802, or from about 502 to about 702C, or from about 55°C to about 65°C. The pressed tobacco product is left in the oil bath for about 5 minutes to about 25 minutes, or about 10 minutes to about 20 minutes to achieve the proper level of lipid impregnation. The temperature of the oil bath and the length of time the pressed tobacco product is in the oil bath also depends in part on the slip point of the lipid used.

After the impregnation operation, the pressed tobacco product is subjected to a heating operation.

Heating can be done in many ways. In one embodiment of the present invention, the heating operation is carried out in a furnace at a temperature of from about 302 to about 702, or from about 402; to about 602C, or from about 4522; to about 55"C. The pressed tobacco product is kept in the oven for about 5 minutes to about 25 minutes, or about 10 minutes to about 20 minutes to achieve a low moisture level (less than about 595). After the oven heating operation, the pressed the tobacco product is held for cooling. In another embodiment of the present invention, there is no heating, and the hot lipid-impregnated tablet is cooled at room temperature. After cooling in this way, the lipid mixture also forms an attractive thin and smooth coating on the surface of the tobacco matrix.

In another embodiment of the present invention, heating is carried out by using a fluidized bed dryer. During fluidized bed heating, a stream of heated air is supplied to the base of a product container filled with pressed tobacco products. Thrust is created with the help of a fan, and fresh air is sucked into the installation. This flow of hot air pushes the products away from each other at a certain speed, creating turbulence among the products. This phenomenon is known as fluidization and causes hot air to stir the pressed tobacco products. Heat transfer is relatively high and uniform. A fluidized bed dryer is available from Vidani Rpapta Maspipegu Gityei, Maharashtra, India and other suppliers. After performing the heating operation in the fluidized bed, the pressed tobacco product is kept for cooling. After cooling, this lipid mixture also forms an attractive thin and smooth coating on the surface of the tobacco matrix.

After cooling the tablet and solidifying the lipids, the dissolved materials remain with the already solid lipid until the pressed tobacco product is placed in the mouth. While in the mouth, the lipids melt, allowing the dissolved flavorings to escape from the pressed tobacco product, which are still in the liquid lipid that coats the tongue and oral mucosa, providing a pleasant, soft mouthfeel. The hydrophobic lipid also inhibits the migration of saliva into the tablet, providing gradual dissolution and reducing chipping of the tobacco matrix, which causes the formation of the "muddy" texture of the known pressed tobacco product. In addition, many flavors and fragrances are hydrophobic and therefore difficult to release from the known pressed tobacco product using only aqueous dissolution in saliva. Instead, the oils allow for easy diffusion of these flavorings and odorants within the oral cavity and retronasal olfactory cavity.

In other embodiments of the present invention, lipid matrices can be added after pressing as a coating using a heating machine for coating, by spraying or cascade glazing. This coating may or may not contain tobacco solids and/or flavorings. The lipid coating may be coated with a thin, fast-dissolving material such as sugars, soluble starches, or combinations thereof to protect the lipid coating from melting at high storage temperatures.

As noted above, in one embodiment, pressed tobacco products manufactured using either pelletizing or direct pressing processes may have a coating. Coating the pressed tobacco product is the last operation before packaging. It is understood that the coating of a pressed tobacco product described herein can provide a moisture barrier, prevent product weathering, improve physical characteristics, maintain integrity, improve brittleness, and potentially increase overall hardness. Commercial coating machines can be used to spray a fine mist of aqueous coating solution into a drum of pressed tobacco products at a controlled rate. The coating process described herein includes the steps of coating a pressed tobacco product with an aqueous dispersion containing a cellulose-based polymer, followed by drying the coated pressed tobacco products, the drying not heating the tablet to more than about 4020.

The coating solution may contain a variety of components, including flavors, colors, sweeteners, and the like. For example, in one of the variants of the implementation of the present invention, the pressed tobacco product can be coated with an aqueous dispersion of hydroxypropylmethylcellulose, polyethylene glycol, titanium dioxide and a dye. In another embodiment of the present invention, the pressed tobacco product is coated with an aqueous dispersion of hydroxypropylmethylcellulose, polyethylene glycol, and maltodextrin. In another embodiment of the present invention, the coating material can be a food polysaccharide. In the process of applying the coating, known equipment can be used, for example, described in Zazig (1998)

React. Oh yeah Thespians 3:423-432; Rapkp (1993) Rnapt. Nev. 10:525-534.

In one embodiment of the present invention, the coating-forming solution is prepared by adding three food components to deionized water and stirring the solution at ambient temperature for a period of time from 20 min to 2 h. The main component, which is hydroxypropyl methylcellulose, is mixed with a plasticizer such as glycerin or triacetin and an aqueous solution of polymer shellac. Polymer shellac provides barrier properties against moisture. The coating film adds from 0.595 to 1095 to the mass of pressed tobacco products.

In another variant of the implementation of the present invention, the pressed tobacco product described herein may have a coating in the form of a hard outer shell applied using the dragging process. It is clear that in this process, pressed tobacco products are rotated in a drum or other device, and the coating material is applied at a low speed to them. During the rotation of the drum, a coating is formed in the form of a hard outer shell on the surface of the pressed tobacco product. In the process described above or in other dredge operations, a wax or gloss may be fed into the drum with the pressed tobacco products to give them an attractive sheen. The rotation of the drum can also contribute to obtaining the final shape of pressed tobacco products.

Pressed tobacco products have such dimensions and shape that ensure their location and use in the oral cavity. Pressed tobacco products can range from about 2 mm to about 30 mm in diameter. Pressed tobacco products are adapted to dissolve completely in less than about 90 minutes, or in less than about 15 minutes, or in less than about 10 minutes.

Pressed tobacco products are made with the possibility of use without residues.

According to another embodiment of the invention, pressed tobacco products can include two or more layers, and adjacent layers are connected to each other (for example, laminated) to form a single pressed tobacco product. All layers in a multi-layer pressed tobacco product may be substantially the same. In another embodiment of the present invention, two or more layers in a multilayer pressed tobacco product may be substantially different. For example, the thickness and composition (eg, the amount and/or distribution and/or type of tobacco component) in each layer in a multilayer pressed tobacco product can be different. These parameters can be varied to provide, for example, different dissolution rates, different flavors or combinations of flavors, different mouthfeels or combinations thereof for each layer. By changing the composition and properties of each layer, the consumer's experience can be changed, increasing satisfaction.

One of the methods of forming a multilayer pressed tobacco product is to bring the mentioned layers into contact with each other when at least one surface of at least one of the layers is not yet completely dried. Alternatively, two or more formed and dried layers may be bonded together by introducing between their respective facing surfaces a binder which adheres to both facing surfaces and binds them to each other. This binder is food grade and contains one or more of the same components used to form the pressed tobacco product, or a water-soluble polysaccharide. The binder may be applied in any suitable manner, for example by spraying or the like.

In another embodiment of the present invention, pressed tobacco products can be placed inside a chewable or dissolvable pouch. This bag provides enough adaptability to make a wide range of different products. For example, a sachet may dissolve relatively quickly in the mouth, while a compressed tobacco product may dissolve more slowly, or may contain flavorings that differ from those contained in the pouch material. It is clear that the result is that the consumer experiences different sensations at different times during the consumption of the product, or that the sensations experienced during the dissolution of the different components cannot be experienced when consuming each component separately.

It is clear that the compositions and methods used to manufacture the pressed tobacco products described herein must be designed to perform their respective functions in three distinct periods: 1) the manufacturing period; 2) the period of existence in the form of a tablet; and 3) the period of consumption and satisfaction by the consumer. It has been found that certain components of the composition and operation of the method, having a beneficial effect in one period, can have a positive or negative effect in another period, as described in more detail below.

In the composition of the tobacco mixture, the use of crushed modified veins provides a higher level of cellulose content in the pressed tobacco product. A higher level of cellulose is more desirable during the manufacturing period because it is useful for making the tablet, and because it gives the product a "softer" taste, it is more desirable during the consumption and consumer satisfaction because it provides particles that pass down better down the throat of the consumer. The use of highly aromatic dark shade-cured tobacco in tobacco blends enables the use of higher levels of chopped modified veins while also providing a high level of satisfaction.

The use of microcrystalline cellulose as an effective binding agent in the binding system is more desirable during the manufacturing period, and is also better during the period of existence in the form of a tablet, as it improves the hardness of the tablet. However, the use of microcrystalline cellulose with too high a content can have a negative effect during consumption and consumer satisfaction, as it increases the formation of grains during dissolution. Using xanthan gum provides several benefits. First, as an effective astringent, it is better during the period of manufacture and period of existence in the form of a tablet. Secondly, it regulates the release of extracted substances, which is useful during the period of consumption and satisfaction by the consumer. After all, it is a carrier of moisture, which is useful in all three periods.

Maltodextrin - another substance of the astringent system - is also useful in all three periods. First, as an effective astringent, it is better during the manufacturing period. Secondly, it improves the hardness of the product, which is useful during the period of existence in the form of a tablet. Third, it improves the texture of the product, reduces sliminess and provides an improved mouthfeel, which is beneficial during consumption and consumer satisfaction.

Pregelatinized cornstarch, which is another component of the binding system, is useful during manufacturing and can play a role in coating the product, but can cause a slimy sensation in the mouth, adversely affecting consumption and consumer satisfaction. Corn starch, such as RioMach 8F), behaves quite differently, improving the hardness of the product, and therefore is better for the period of existence in tablet form.

Sweeteners are used in order to obtain their effect during the period of consumption and satisfaction by the consumer. The substances Zysgazzeekyu and sucralose were found to be beneficial for consumption and consumer satisfaction. Although polyhydric alcohols have been shown to provide sufficient sweetness, they also act as a rapid release impurity in relation to extractables and therefore have a negative impact on consumption and consumer satisfaction. In addition, polyhydric alcohols have shown a negative effect on the hardness of the product, thus also having a negative effect on the period of existence in tablet form.

Lubricants are used to gain an advantage during the manufacturing process. Although magnesium stearate is an effective lubricant, when used at too high a content level, it can reduce the hardness of the product and have a negative effect during the period of existence in tablet form. As mentioned above, the application of fumed colloidal silica can perform three important functions simultaneously. First, it is an effective lubricant, which is useful during the manufacturing period. Secondly, it is a moisture absorber, which is useful during the period of manufacture and during the period of existence in the form of a tablet. As a moisture absorber, pyrogenic colloidal silica prevents the absorption of moisture by finely ground tobacco.

Third, it is a lubricant, which is useful during the periods of manufacture and consumption and enjoyment by the consumer.

Flavorings and fragrances may be used to enhance consumption and consumer satisfaction. Flavors and fragrances suitable for such use are essential oils, natural ground coffee, tea, cocoa and mint, as well as essences of coffee, tea, cocoa and mint.

It was found that several properties of the finished product, including dissolution and flavoring indicators, can be influenced by adjusting the following variable parameters: 1) tablet porosity, 2) tobacco particle size distribution, 3) particle size distribution of other components, 4) time interval , during which the pressed tobacco product is in the lipid-oil bath, 5) the temperature of the lipid-oil bath, 6) the sliding temperature of the lipid or lipid mixtures, 7) the level of lipid seepage, 8) the drying temperature of the pressed tobacco product, and 9) the interaction or combination , or both an interaction and a combination of these parameters. In addition, it was found that the porosity of tablets from a pressed tobacco product, and thus the level of lipid percolation, can be regulated by pressing pressure or the composition of the substance of the tablet, or a combination of both. Additional tablet properties can be obtained by adding flavors, sweeteners, warmers, coolers, gas-releasing matrices, or a combination of some or all of these components. Additional external coatings are used, such as wax, sugars, polyhydric alcohols, proteins, polysaccharides. To prevent the release of lipids at high temperatures during storage, oligosaccharides, etc., may be added.

Testing of the products showed that the lipid-impregnated pressed tobacco product acquires the properties of an improved aroma and texture. In addition, clearer soft characteristics of dissolution in the mouth are achieved. Other benefits include improved delivery of hydrophobic flavors and fragrances, as well as reduced heartburn and throat irritation. | finally, as noted above, the lipid-impregnated pressed tobacco products described herein have an attractive appearance both in terms of color and visible texture.
