Smokeless Tobacco Products
• In various embodiments, the invention described herein relates to a smokeless tobacco product, comprising a tobacco composition and an encapsulating composition coating the tobacco composition, wherein the encapsulating composition comprises methyl salicylate.
• The tobacco composition can comprise, for example, a salt solution infused fermented tobacco blend and/or a slurry comprising water and a tobacco material. Various examples of the tobacco composition are described in U.S. Pat. Pub. Nos. 2011/0061666 titled “Smokeless Tobacco Composition.”
• In a first set of embodiments of the smokeless tobacco product, the encapsulating composition can comprise an external phase and an internal phase. The external phase can represent, for example, 1-40 wt. % of the encapsulating composition. In one embodiment, the external phase represents 2-25 wt. % of the encapsulating composition. In another embodiment, the external phase represents 5-20 wt. % of the encapsulating composition. In a further embodiment, the external phase represents 10-15 wt. % of the encapsulating composition. The internal phase can represent, for example, 60-99 wt. % of the encapsulating composition. In one embodiment, the internal phase represents 75-98 wt. % of the encapsulating composition. In another embodiment, the internal phase represents 80-95 wt. % of the encapsulating composition. In a further embodiment, the internal phase represents 85-90 wt. % of the encapsulating composition.
• The external phase of the encapsulating composition can comprise, for example, methyl salicylate blended with a low HLB surfactant solution. HLB refers to the hydrophilic-lipophilic balance of a surfactant, which is a measure of the degree to which it is hydrophilic or lipophilic. A low HLB surfactant as described herein generally refers to a surfactant having an HLB value of 10 or less. Common low HLB surfactants are described in Griffin, J.Soc'y Cosmetic Chemists,1949, 1(5):311-26; Griffin,J. Soc'y Cosmetic Chemists,1954, 5(4):249-56; and Davies,Proc. Int'l Cong. Surface Activity,1957, 426-38; which are incorporated herein by reference.
• Methyl salicylate can represent, for example, 5-60 wt. % of the external phase. In one embodiment, methyl salicylate represents 10-50 wt. % of the external phase. In another embodiment, methyl salicylate represents 15-40 wt. % of the external phase. In a further embodiment, methyl salicylate represents 20-30 wt. % of the external phase.
• The internal phase of the encapsulating composition can comprise, for example, an aqueous solution. The aqueous solution can comprise, for example, at least one humectant (e.g., glycerin or propylene glycol). The aqueous solution can comprise, for example, at least one salt (e.g., sodium chloride or potassium chloride).
• The first set of embodiments of the smokeless tobacco product can comprise, for example, no more than 5 wt. % of methyl salicylate, based on the total weight of the encapsulating composition and the tobacco composition. In one embodiment, the smokeless tobacco product comprises no more than 4 wt. % of methyl salicylate. In another embodiment, the smokeless tobacco product comprises no more than 3 wt. % of methyl salicylate. In a further embodiment, the smokeless tobacco product comprises no more than 2.5 wt. % of methyl salicylate. In yet another embodiment, the smokeless tobacco product comprises no more than 2 wt. % of methyl salicylate. In yet a further embodiment, the smokeless tobacco product comprises no more than 1.5 wt. % of methyl salicylate.
• In a second set of embodiments of the smokeless tobacco product, the encapsulating composition can be substantially or totally free of an internal phase of an aqueous solution. The encapsulating composition can comprise, for example, methyl salicylate blended with a low HLB surfactant solution.
• Methyl salicylate can represent, for example, 5-60 wt. % of the external phase. In one embodiment, methyl salicylate represents 10-50 wt. % of the external phase. In another embodiment, methyl salicylate represents 15-40 wt. % of the external phase. In a further embodiment, methyl salicylate represents 20-30 wt. % of the encapsulating composition.
• The second set of embodiments of the smokeless tobacco product can comprise, for example, no more than 5 wt. % of methyl salicylate, based on the total weight of the encapsulating composition and the tobacco composition. In one embodiment, the smokeless tobacco product comprises no more than 4 wt. % of methyl salicylate. In another embodiment, the smokeless tobacco product comprises no more than 3 wt. % of methyl salicylate. In a further embodiment, the smokeless tobacco product comprises no more than 2.5 wt. % of methyl salicylate. In yet another embodiment, the smokeless tobacco product comprises no more than 2 wt. % of methyl salicylate. In yet a further embodiment, the smokeless tobacco product comprises no more than 1.5 wt. % of methyl salicylate.
Method for Producing Smokeless Tobacco Products
• The present invention described herein also relates to a method for producing a smokeless tobacco product, comprising coating a tobacco composition with an encapsulating composition comprising methyl salicylate. The method can comprise, for example, topically applying the encapsulating composition onto the tobacco composition.
• The method can comprise, for example, coating a tobacco composition comprising a salt solution infused fermented tobacco blend, with an encapsulating composition comprising an external phase comprising 10-50 wt. % of methyl salicylate blended with a low HLB surfactant solution and an internal phase comprising an aqueous solution comprising at least one humectant. The resulting smokeless tobacco product comprises no more than 3 wt. % of methyl salicylate.
• The method can also comprise, for example, coating a tobacco composition comprising a salt solution infused fermented tobacco blend, with an encapsulating composition comprising 10-50 wt. % of methyl salicylate blended with a low HLB surfactant solution and substantially free of an aqueous internal phase, wherein the smokeless tobacco product obtained comprises no more than 3 wt. % of methyl salicylate.
• In one particular aspect, the method can comprise, for example, coating a tobacco slurry uniformly with 1-3 wt. % methyl salicylate, which could function as a flavoring component. The methyl salicylate can be applied to the slurry as 10-50 wt. % of the encapsulating/external phase of a liquid encapsulation. Within this liquid encapsulation, 2-25 wt. % can be the encapsulating/external phase, and 75-98 wt. % can be the encapsulated/internal phase. The encapsulating/external phase can comprise of a solution of methyl salicylate and a low HLB surfactant and the encapsulated/internal phase can be a water solution. The encapsulating external phase can also include other GRAS lipids. The internal phase water solution may contain various combinations of salts and/or humectants as well as various suspended solid, including but not limited to a portion of the tobacco slurry. Although the external phase can be only 2-25% of the encapsulation, the external phase can be 100% of the surface area of the encapsulation. Therefore, a very effective flavor coating can be possible with levels of methyl salicylate at only 1-3 wt. % or less of the total slurry. In addition, the external phase methyl salicylate/low HLB surfactant solution can be coated directly onto the slurry, without including the internal phase water solution. The result is also a high percentage methyl salicylate film coating, wherein the total slurry has a low percentage of methyl salicylate.
• According to one aspect of the present disclosure, the tobacco composition may be treated with a methyl salicylate/low HLB solution external phase liquid/liquid encapsulation or a methyl salicylate/low HLB solution blend can be characterized as snuff.
Tobacco Product Package
• According to various other embodiments, a coating layer comprising methyl salicylate may be applied to a tobacco product container. In particular embodiments, the methyl salicylate-containing coating layer is used in the place of applying the methyl salicylate to the tobacco itself. However, it is possible to both include a methyl salicylate-containing coating layer as well tobacco products including a methyl salicylate coating.
• FIG. 1 is a representation of an exemplarytobacco product container10 for which such embodiments may be implemented. Thetobacco product container10 comprises alid15 and acontainer body20. Both thelid15 and thecontainer body20 can be formed from a variety of materials, including but not limited to metals such as tin, aluminum and the like, as well as plastic and other materials. Thetobacco product container10 can possess a variety of shapes and sizes. By way of example, the cross section of thetobacco product container10 can be circular, square, rectangular, trapezoidal, ovular, or virtually any other shape. Although the container embodiments illustrated in the drawings have certain contours, containers with other exterior surface designs also can be suitably adapted and used. For example, the sides or edges of the containers of the disclosure can be flattened, rounded, or beveled, and the various surfaces or edges of the container exterior can be concave or convex. Further, the opposing sides, ends, or edges of the container can be parallel or non-parallel such that the container becomes narrower in one or more dimensions. Additionally, the size and shape of the cross-section can vary between the bottom and the top of thetobacco product container10.
• As discussed in greater detail below, thelid15 and thecontainer body20 are configured to selectively engage and disengage from each other. For example, thelid15 can “snap fit” with thecontainer body20, or the engagement can occur via one or more threads located on both thelid15 and thecontainer body20. In the embodiment depicted inFIG. 1, thelid15 and thecontainer body20 are depicted as being entirely separate components. However, it is also possible for thelid15 and thecontainer body20 to be hingedly connected to each other, or these components can be movably connected to each other (such that thetobacco product container10 can be opened or closed) by other mechanisms known in the art.
• Thelid15 includes atop portion25 and at least onelid side wall30 extending from thetop portion25. The at least onelid side wall30 includes a containerbody engagement region35, as discussed in greater detail below. The at least onelid side wall30 includes a lid side wallinner surface40 and a lid side wallouter surface45.
• Thecontainer body20 includes abase portion50 and at least one containerbody side wall55 extending from thebase portion50. Thebase portion50 and the at least one containerbody side wall55 cooperate to define a tobacco storage volume therein60, within which tobacco product65 may be stored. The at least one container body side wall includes a container body side wallinner surface70 and a container body side wallouter surface75. The at least one containerbody side wall55 also includes alid engagement region80.
• The containerbody engagement region35 and thelid engagement region80 are positioned so as to engage or otherwise contact each other when thelid15 is secured to thecontainer body20. For example, inFIG. 1 the lid side wallinner surface40 engages the container body side wallouter surface75. In this arrangement, the containerbody engagement region35 is located on the lid side wallinner surface40 at the position where the lid side wallinner surface40 contacts the container body side wallouter surface75, and thelid engagement region80 is located on the container body side wallouter surface75 at the position where the container body side wallouter surface75 contacts the lid side wallinner surface40. In the opposite configuration, where the container body side wallinner surface70 contacts the lid side wallouter surface45, the containerbody engagement region35 and thelid engagement region80 are located on these respective regions.
• A coating layer comprising methyl salicylate (and potentially other aroma inducing substances) is positioned on at least one of thelid engagement region80 and the containerbody engagement region75 such that, when thelid15 is disengaged from thecontainer body20, the methyl salicylate is exposed to an environment outside of the tobacco storage volume. Depending upon the particular arrangement, the coating layer can be located entirely on thelid engagement region80, entirely on the containerbody engagement region75, or on both thelid engagement region80 and the containerbody engagement region75. In each case, the coating layer releases aroma upon the disengagement of thelid15 from thecontainer body20.
• The coating layer can comprise, for example, 1-99 wt. % of methyl salicylate. In one embodiment, the coating layer comprises 5-90 wt. % of methyl salicylate. In another embodiment, the coating layer comprises 10-50 wt. % of methyl salicylate. The coating layer can comprise, for example, at least one humectant and/or salt.
• In these various embodiments, removing thelid15 from thecontainer body20 results in exposing the coating layer, which thereby releases an enjoyable and satisfying aroma sensible to the user. The coating layer, however, is substantially or totally free of any direct contact with the tobacco product65 stored in the casing. Thus, the tobacco product65 consumed by the user is substantially or completely free of methyl salicylate derived from the coating layer.
• In a particular implementation, the physical disengagement of thelid15 and thebody20 physically assists in the release of the aroma associated with the methyl salicylate. More particularly, when the lid disengages from the body, the movement of the containerbody engagement region75 relative to thelid engagement region80, both of which are in contact with each other, causes a release of some of the methyl salicylate (and any associated wintergreen or other aroma) that is contained in the coating layer.
Additional Description of Tobacco Composition
• The tobacco composition described herein may include tobacco itself or components or elements found in or otherwise associated with tobacco. In some instances, the tobacco composition is preferably formed of a heterogeneous material (i.e., not a wax, gel, or other homogeneous material). In other instances, the tobacco composition may preferably be configured or arranged so as to be exclusive or free of a carrier matrix (i.e., tobacco without a physical support framework), though, in particular instances, the tobacco composition may include a carrier matrix so as to form individual stand-alone portions of the tobacco composition. In some instances, for example, where the tobacco composition comprises a moist snuff, the tobacco composition may be characterized as portions of tobacco having a thick slurry consistency. In particular instances, the portions of tobacco forming the moist snuff are not suspended in a carrier material (i.e., the tobacco composition does not comprise a minority or portions of tobacco suspended in a wax or gel or another homogeneous type of carrier). A moist snuff type of product may further be characterized as a product wherein the tobacco pieces have the propensity or affinity to form or stick together (i.e., to form a cohesive entity) without a carrier, but wherein the overall formulation can be characterized as more cohesive in nature than a comparable moist snuff formulation not incorporating a binder. The moisture content in a moist snuff type of product may also vary. For instance, the moisture content in a moist snuff type of product may vary between about 40 parts and about 60 parts by weight, wherein it may be preferred that such a moist snuff type of product have a moisture content of between about 50 parts and about 55 parts by weight. A pasteurized moist snuff type of product, however, may have relatively low moisture content.
• In particular aspects, the tobacco composition may comprise one of moist snuff, snus, loose leaf tobacco, plug tobacco, tobacco pellets, tobacco pieces, and combinations thereof. In forming the thick slurry (or moist cohesive mass) consistency product, the tobacco composition may include, for example, at least tobacco and water that can be mixed or formed into a generally dough-like, moist consistency incorporating pieces of smokeless tobacco; and the slurry can optionally incorporate at least one salt (e.g., sodium chloride or potassium chloride), at least one buffer (e.g., ammonium carbonate, sodium carbonate, sodium bicarbonate, potassium carbonate, ammonium bicarbonate, or potassium bicarbonate), at least one sweetener (e.g., sucrose, glucose, high fructose corn syrup or a synthetic sweetener), flavoring agents commonly used for flavoring smokeless tobacco formulations, at least one binding agent, at least one preservative agent, and the like, as well as combinations thereof.
• In particular aspects, the selection of the plant from theNicotianaspecies utilized in the products and processes of the disclosure can vary; and in particular instances, the types of tobacco or tobaccos may vary. Tobaccos that can be implemented include flue-cured or Virginia (e.g., K326), burley, sun-cured (e.g., Indian Kurnool and Oriental tobaccos, including Katerini, Prelip, Komotini, Xanthi and Yambol tobaccos), Maryland, dark, dark-fired, dark air cured (e.g., Passanda, Cubano, Jatin and Bezuki tobaccos), light air cured (e.g., North Wisconsin and Galpao tobaccos), Indian air cured, Red Russian and Rustica tobaccos, as well as various other rare or specialty tobaccos. Descriptions of various types of tobaccos, growing practices and harvesting practices are set forth in Tobacco Production, Chemistry and Technology, Davis et al. (Eds.) (1999), which is incorporated herein by reference. Various representative types of plants from theNicotianaspecies are set forth in Goodspeed, The GenusNicotiana,(Chonica Botanica) (1954); U.S. Pat. No. 4,660,577 to Sensabaugh, Jr. et al.; U.S. Pat. No. 5,387,416 to White et al.; U.S. Pat. No. 7,025,066 to Lawson et al.; and U.S. Pat. No. 7,798,153 to Lawrence, Jr.; and US Patent Appl. Pub. Nos. 2008/0245377 to Marshall et al. and 2013/0312774 to Holton; each of which is incorporated herein by reference.
• For the preparation of tobacco products, such as smokeless tobacco products, it is typical for harvested plants of theNicotianaspecies to be subjected to a curing process. Descriptions of various types of curing processes for various types of tobaccos are set forth in Tobacco Production, Chemistry and Technology, Davis et al. (Eds.) (1999). Exemplary techniques and conditions for curing flue-cured tobacco are set forth in Nestor et al., Beitrage Tabakforsch. Int, 20, 467-475 (2003) and U.S. Pat. No. 6,895,974 to Peele, which are incorporated herein by reference. Representative techniques and conditions for air curing tobacco are set forth in Roton et al., Beitrage Tabakforsch. Int., 21, 305-320 (2005) and Staaf et al., Beitrage Tabakforsch. Int., 21, 321-330 (2005), which are incorporated herein by reference. Certain types of tobaccos can be subjected to alternative types of curing processes, such as fire curing or sun curing. Typically, harvested tobaccos that are cured are then aged.
• At least a portion of the plant of theNicotianaspecies (e.g., at least a portion of the tobacco portion) can be employed in various forms. For example, various parts or portions of the plant of theNicotianaspecies can be employed. Additionally, various parts or portions of the plant of theNicotianaspecies can be subjected to various types of post-harvest processing treatments or processes. For example, such parts or portion of the plant can be separated into individual parts or pieces, physically processed or subjected to extraction (e.g., solvent extraction using polar solvents, organic solvents, or supercritical fluids, chromatography, distillation, filtration, recrystallization, and/or solvent-solvent partitioning). See, for example, US Patent Appl. Pub. No. 2013/0312774 to Holton, which is incorporated herein by reference.

• In yet other aspects of the present disclosure, the tobacco composition that is to be coated and/or packaged according to the present invention can have the form of a plurality of individual parts or pieces. Generally, such types of tobacco composition can have the form or general shape of cylinders or pellets, beans or ovoids, capsules, compressed or formed spheres or bits, tablets, lozenges, or the like. For example, the tobacco composition can have a form that can be characterized as compressed tobacco tablets, such a product that has been commercially available as Interval Tobacco Tabs through Brown & Williamson Tobacco Corporation. Alternatively, the tobacco composition can have the form of compressed tobacco pieces that have been marketed under the tradename Camel Orbs by R. J. Reynolds Tobacco Company. The tobacco composition also can have the form of parts or pieces of so-called plug type chewing tobacco, such as can be provided by suitable adaptation of products that have been commercially available as Redman Original, Granger Select and Beech-Nut Original by Pinkerton Tobacco Co. LP. Exemplary pieces of a tobacco composition have the form of pieces, pellets or bits, such as those available under the tradename Oliver Twist Original and Oliver Twist Sunberry by House of Oliver Twist A/S (See, e.g., U.S. Pat. No. 8,635,847 to Knudsen). Additionally, processed tobacco composition can be formed into generally disc-shaped pieces; such as, for example, as a plurality of disc-shaped pieces each having a central passageway, so that those discs can be stacked on top of each other and provide for the central ejection mechanism of the container. Other representative types of tobacco composition, product formulations and product configurations are set forth, discussed and referenced, for example, in US Pat. App. Pub. Nos. 2011/0220130 to Mua et al., 2013/0206150 to Duggins et al., 2013/0206153 to Beeson et al., 2013/0263870 to Cantrell et al., 2013/0274296 to Jackson et al. and 2013/0312774 to Holton, which are incorporated herein by reference. Compared to these products, the smokeless tobacco products describe herein comprises less methyl salicylate and hence is healthier.
• In still other aspects of the present disclosure, the tobacco composition that is to be coated and/or packaged according to the present invention can otherwise be characterized as being based on loose leaf tobacco, plug tobacco, tobacco pellets, tobacco bits, or otherwise tobacco pieces, or combinations thereof In some instances, the tobacco composition according to such aspects may include a binder material or substance to facilitate or promote cohesion of the product. Such a binder material or substance may include, for example, gum arabic, gum ghatti, guar gum, pectin, psyllium, carrageenan, xanthan, tragacanth, caraya, locust bean gum, konjac gum, agar, gelatin, an alginate, rice flour, wheat flour, oat flour, corn flour, rye flour, potato flour, starches, modified starches, whey, lactose, sucrose, maltitol, sorbitol, xylitol, carboxymethyl cellulose, microcrystalline cellulose, hydroxypropyl cellulose, methylcellulose and hydroxypropyl methylcellulose. One or more of such representative binders materials or substance may be incorporated into liquid (e.g., aqueous) formulations that are used for the preparation, for example, of moist snuff tobacco composition. For example, at least one binder can be incorporated in a desired amount into a casing formulation that is used to moisten and flavor a tobacco mixture used to produce a moist snuff product. As a result, the resulting flavored moist snuff product may have the form of a mixture of parts or pieces of moist tobacco.
• Many modifications and other aspects of the disclosures set forth herein will come to mind to one skilled in the art to which these disclosures pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the disclosures are not to be limited to the specific aspects disclosed and that equivalents, modifications, and other aspects are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
