Description

Technical Field

[0001] This application relates to the field of cigarette technology, and in particular to cigarette flavoring casings and their applications. Background Technology

[0002] Currently, the flavor release units widely used in cigarette filters are mostly soft capsules (commonly known as "flavor beads"). Their outer shells are usually made of polymer gel materials such as gelatin, starch, or agar, and the inside contains liquid flavoring. Consumers squeeze the capsule to break the shell and release the flavor. This technology has been applied to some extent in cigarette products, but it still has many limitations and cannot meet consumers' high-quality demands for flavor release experience.

[0003] Traditional popping beads are made of gel material, which is highly resilient. Consumers need to apply a lot of pressure to break the shell, and the breaking sensation is not clear. The shell may deform but not break completely, which means that the liquid fragrance inside cannot be fully released. This not only affects the consistency of the fragrance experience but may also result in fragrance waste.

[0004] Therefore, traditional technologies still need improvement. Summary of the Invention

[0005] Based on this, this application provides a tobacco flavoring shell with better brittleness and more complete and uniform aroma release, and its application.

[0006] The specific technical solution is as follows:

[0010] Plasticizer 0~2%;

[0011] Inorganic fillers 0~5%;

By controlling the specific proportions of each raw material, the components work together to ensure that the tobacco flavoring shell undergoes brittle fracture under relatively low external mechanical pressure, thereby ensuring the full release of the core flavoring substances. The formed shell has good barrier properties against oxygen and moisture, which helps extend the product's shelf life and maintain the stability of the flavoring substances.

[0036] Another aspect of this application provides a tobacco flavoring, including a core and a shell covering the core, the shell including the aforementioned tobacco flavoring shell.

[0038] And / or, the particle size of the tobacco flavoring is 2.5 mm to 4.0 mm.

Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0045] The implementation of this application will be described in detail below with reference to some implementation methods and embodiments. This embodiment is implemented based on the technical solution of this application, and provides detailed implementation methods and specific operation processes, but the protection scope of this application is not limited to the following embodiments.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0047] Unless otherwise stated or in case of contradiction, the terms or phrases used herein shall have the following meanings:

[0048] In this application, the terms "multiple" or "various" are used unless otherwise specified, referring to a quantity greater than or equal to 2. For example, "one or more" means one or more types.

[0049] In this application, terms such as "further" and "especially" are used to describe purposes and indicate differences in content, but should not be construed as limiting the scope of protection of this application.

[0050] In this application, the technical features described in an open-ended manner include both closed technical solutions consisting of the listed features and open technical solutions that include the listed features.

[0051] In this application, when numerical intervals (i.e., numerical ranges) are mentioned, unless otherwise specified, the distribution of selectable numerical values ​​within the numerical interval is considered continuous, and includes the two endpoints of the numerical interval (i.e., the minimum and maximum values), as well as every numerical value between these two endpoints. Unless otherwise specified, when a numerical interval refers only to integers within that numerical interval, including the two endpoint integers of the numerical range, as well as every integer between the two endpoints, is equivalent to directly listing every integer. When multiple numerical ranges are provided to describe features or characteristics, these numerical ranges can be merged. In other words, unless otherwise specified, the numerical ranges disclosed herein should be understood to include any and all subranges included therein. The "numerical value" in the numerical interval can be any quantitative value, such as a number, percentage, ratio, etc. The term "numerical interval" can be broadly included to include numerical interval types such as percentage intervals, ratio intervals, and proportion intervals.

[0052] In this application, unless otherwise specified, the temperature parameters are permitted to be either constant temperature treatment or variations within a certain temperature range. It should be understood that the constant temperature treatment allows temperature fluctuations within the precision range controlled by the instrument. Fluctuations are permitted within ranges such as ±5℃, ±4℃, ±3℃, ±2℃, and ±1℃.

[0053] In this application, if the unit of a data range is only followed by the right endpoint, it indicates that the units of the left and right endpoints are the same. For example, 2-5 h means that the units of the left endpoint "2" and the right endpoint "5" are both h (hours).

[0054] The term "water" as used in this application can be, independently, distilled water, purified water, filtered water, deionized water, etc.

[0055] First, traditional flavor capsules are prone to deforming the outer shell without fully rupturing, resulting in incomplete release of the encapsulated liquid flavoring. Second, traditional flavor capsules are mostly spherical solid structures (flavoring core, gel outer shell), with limited surface area. When the outer shell ruptures, the contact area between the flavoring and the mainstream cigarette smoke is small, leading to low mixing efficiency and poor uniformity, failing to achieve rapid and complete fusion of flavor and smoke. Furthermore, the flavor release curve of traditional flavor capsules has significant flaws. Because the flavoring is concentrated within the spherical core, a large amount is rapidly released upon rupture, resulting in a strong initial flavor release that quickly diminishes due to rapid flavor consumption. Consumers cannot obtain a consistent and stable flavor experience during vaping, severely impacting the consistency of the vaping taste.

[0056] Based on this, one embodiment of this application provides a cigarette flavoring shell, wherein the raw materials for preparing the cigarette flavoring shell, by mass percentage, include the following components:

[0057] Brittle matrix materials: 70%~95%;

[0058] Molding stabilizer 4%~25%;

[0059] Plasticizer 0~2%;

[0060] Inorganic fillers 0~5%;

[0061] Water 0.5%~5%;

[0062] The brittle matrix material includes one or more of monosaccharides, disaccharides, and sugar alcohols; the molding stabilizer includes one or more of natural colloids and maltodextrin.

[0063] The tobacco flavoring shell of this application comprises specific components and their specific proportions. A brittle matrix material serves as the main body for forming the glassy matrix, providing the primary brittle structure; a molding stabilizer is used to improve the workability of the slurry, increase the strength of the green body, and fine-tune the brittle fracture characteristics of the final product; further, plasticizers, inorganic fillers, and water are used in synergistic effects. By controlling the specific proportions of each raw material, the components work together to ensure that the tobacco flavoring shell undergoes brittle fracture under relatively low external mechanical pressure, thereby ensuring the full release of the core flavoring substances. The formed shell has good barrier properties against oxygen and moisture, which helps extend the product's shelf life and maintain the stability of the flavoring substances.

[0064] It should be noted that the range of the above-mentioned brittle matrix material addition amount is "70%~95%", which means taking the minimum and maximum values ​​within the range of 70%~95%, as well as every value between these minimum and maximum values. Specific examples include, but are not limited to, the point values ​​in the embodiments and the following point values: 70.0%, 70.5%, 71.0%, 71.5%, 72.0%, 72.5%, 73.0%, 73.5%, 74.0%, 74.5%, 75.0%, 75.5%, 76.0%, 76.5%, 77.0%, 77.5%, 78.0%, 78.5%, 79.0%, 79.5%, 80.0%, 80.5%, 81.0%, 81.5%, 82.0%, 82.5%, 83 0.0%, 83.5%, 84.0%, 84.5%, 85.0%, 85.5%, 86.0%, 86.5%, 87.0%, 87.5%, 88.0%, 88.5%, 89.0%, 89.5%, 90.0%, 90.5%, 91.0%, 91.5%, 92.0%, 92.5%, 93.0%, 93.5%, 94.0%, 94.5% or 95.0%; or a range consisting of any two of these values, for example, including: 75%~95%.

[0065] The range of the amount of molding stabilizer to be added is "4%~25%", which means taking the minimum and maximum values ​​of the range of 4%~25%, as well as every value between the minimum and maximum values. Specific examples include, but are not limited to, the point values ​​in the embodiments and the following point values: 4.0%, 4.5%, 5.0%, 5.5%, 6.0%, 6.5%, 7.0%, 7.5%, 8.0%, 8.5%, 9.0%, 9.5%, 10.0%, 10.5%, 11.0%, 11.5%, 12.0%, 12.5%, 13.0%, 13.5%, 14.0%, 14.5%, 15.0%, 15.5%, 16.0%, 16.5%, 17.0%, 17.5%, 18.0%, 18.5%, 19.0%, 19.5%, 20.0%, 20.5%, 21.0%, 21.5%, 22.0%, 22.5%, 23.0%, 23.5%, 24.0%, 24.5%, or 25.0%; or a range consisting of any two of these values, for example, including: 10%~25%.

[0066] The range of plasticizer addition is "0~2%", which means the minimum and maximum values ​​within the range of 0~2%, as well as every value between these two values. Specific examples include, but are not limited to, the point values ​​in the examples and the following point values: 0.0%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, or 2.0%; or a range consisting of any two of these values. For example, this includes: 1%~2%.

[0067] The range of inorganic filler addition is "0~5%", which means taking the minimum and maximum values ​​of the range of 0~5%, as well as every value between the minimum and maximum values. Specific examples include, but are not limited to, the point values ​​in the embodiments and the following point values: 0.0%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 18%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3.0%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5%, 3.6%, 3.7%, 3.8%, 3.9%, 4.0%, 4.1%, 4.2%, 4.3%, 4.4%, 4.5%, 4.6%, 4.7%, 4.8%, 4.9% or 5.0%; or a range consisting of any two of these values, for example, including: 1%~5%.

[0068] The range of water added is "0.5%~5%", which means taking the minimum and maximum values ​​within the range of 0.5%~5%, as well as every value between these minimum and maximum values. Specific examples include, but are not limited to, the point values ​​in the embodiments and the following point values: 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 18%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3.0%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5%, 3.6%, 3.7%, 3.8%, 3.9%, 4.0%, 4.1%, 4.2%, 4.3%, 4.4%, 4.5%, 4.6%, 4.7%, 4.8%, 4.9% or 5.0%; or a range consisting of any two of these values, for example, including: 1% to 5%.

[0069] In some embodiments, the raw materials for preparing the above-mentioned tobacco flavoring shell, by mass percentage, include the following components:

[0070] Brittle matrix materials: 74%~94.5%;

[0071] Molding stabilizer 4%~24%;

[0072] Plasticizer 0.5%~2%;

[0073] Inorganic fillers 0%~5%;

[0074] Water content: 0.5%~5%.

[0075] In some embodiments, the monosaccharide mentioned above includes one or more of glucose and fructose.

[0076] In some embodiments, the disaccharide mentioned above includes one or more of sucrose and trehalose.

[0077] In some embodiments, the sugar alcohols mentioned above include one or more of isomaltitol, sorbitol, maltitol, and xylitol.

[0078] In some embodiments, the aforementioned natural colloids include one or more of gum arabic, gellan gum, carrageenan, agar, pectin, and xanthan gum.

[0079] Understandably, the aforementioned sugars and / or sugar alcohols, as the main components forming the glassy matrix, provide the primary brittle structure; the aforementioned natural colloids and maltodextrin, as film-forming agents and reinforcing agents, improve the workability of the slurry, increase the strength of the green body, and fine-tune the brittle-crack characteristics of the final product. Both work synergistically and are indispensable. If the proportion of brittle matrix material is too low, the brittleness will be insufficient; if the proportion of molding stabilizer is too low, molding will be difficult, and the mechanical integrity of the shell will be poor.

[0080] In some embodiments, the plasticizer includes one or more of glycerol and propylene glycol.

[0081] In some embodiments, the inorganic filler includes one or more of silica and calcium carbonate.

[0082] It is understandable that controlling the plasticizer within the aforementioned specific range can moderately reduce brittleness while retaining controllable brittleness. This simultaneously improves the molding qualification rate of the shell, prevents drying cracking, and achieves a better plasticizing effect. It also prevents excessive softening of the shell, loss of brittleness, and an increase in brittle fracture pressure. Controlling the inorganic filler within the aforementioned specific range can achieve an anti-caking effect, enhance the hardness of the shell, prevent premature cracking or damage due to external stress, and ensure the structural integrity of the fragrance unit.

[0083] In some embodiments, the aforementioned brittle matrix material is isomaltitol;

[0084] The above-mentioned molding stabilizer is maltodextrin;

[0085] The aforementioned inorganic filler is nano-silica; or

[0086] The aforementioned brittle matrix material is isomaltitol;

[0087] The above-mentioned molding stabilizer is maltodextrin;

[0088] The plasticizer mentioned above is glycerin; or

[0089] The aforementioned brittle matrix material is sucrose;

[0090] The molding stabilizer mentioned above is gum arabic;

[0091] The plasticizer mentioned above is glycerin.

[0092] Another embodiment of this application provides a tobacco flavoring, including a core and a shell wall material covering the core, wherein the shell wall material includes the tobacco flavoring shell.

[0093] In some embodiments, the shape of the above-mentioned tobacco flavoring includes one or more of icosahedron, dodecahedron, and truncated icosahedron.

[0094] Understandably, the stress concentration effect generated by the polyhedral structure, combined with the brittle shell material, allows consumers to obtain a clear and distinct cracking sensation and auditory feedback with relatively low pressure, ensuring the full release of flavor substances. Furthermore, the hollow polyhedral structure provides a large specific surface area, enabling flavor substances to diffuse and mix more rapidly and evenly upon contact with the smoke, improving the uniformity and consistency of the vaping experience.

[0095] In some embodiments, the particle size of the above-mentioned tobacco flavoring is 2.5 mm to 4.0 mm.

[0096] Another embodiment of this application provides a method for preparing tobacco flavoring, including the following steps S100 to S200.

[0097] Step S100: After mixing the above-mentioned raw materials for preparing the tobacco flavor shell, the mixture is molded to prepare the intermediate shell.

[0098] In some embodiments, the molding process includes one or more of micromolding, template molding, and 3D printing.

[0099] In one specific example, micromolding involves injecting or pressing a tobacco flavoring shell slurry into a micro-mold with a polyhedral cavity, followed by demolding after curing.

[0100] In one specific example, template forming includes forming and curing a tobacco flavoring shell slurry on a continuous template with polyhedral pits.

[0101] In one specific example, 3D printing involves using a 3D printing device to deposit tobacco flavoring shell slurry layer by layer to construct a hollow shell.

[0102] Step S200: Inject the flavoring substance into the above intermediate shell, seal it, and prepare tobacco flavoring.

[0103] In some embodiments, the fragrance substance includes one or more of liquid fragrance, gel fragrance, or solid fragrance powder.

[0104] In some embodiments, the aforementioned gelled fragrance comprises flavoring substances combined with gelling agents (such as gellan gum or carrageenan).

[0105] In some embodiments, the fragrance substance includes one or more of fragrance and peppermint essential oil.

[0106] In some embodiments, the sealing method includes one or more of heat sealing, laser sealing, solvent sealing, and syrup sealing.

[0107] In one specific example, heat sealing involves precisely aligning and covering another half-shell within the intermediate shell, applying heat and pressure to cause the materials at the bonding surfaces to slightly melt and fuse, and then cooling to form a seamless connected shell.

[0108] In one specific example, laser sealing involves scanning the mating surfaces of the intermediate housing with a laser of a certain wavelength, causing the materials to absorb energy and fuse instantly, thus achieving a non-contact precision seal.

[0109] In one specific example, solvent sealing involves applying a certain amount of solvent (such as an ethanol / water mixture) capable of dissolving the shell material to the bonding surface of the intermediate shell, thereby activating its surface. After pressing, the molecular chains become entangled with each other, and a strong bond is achieved after the solvent evaporates.

[0110] In one specific example, sugar encapsulation involves using a syrup with a higher concentration of components than the shell as a "natural glue," which is applied to the bonding surface of the intermediate shell and then pressed and cured.

[0111] In some embodiments, the mass ratio of the tobacco flavoring shell to the flavoring substance is 1:0.2 to 1:0.8.

[0112] It is understandable that controlling the mass ratio of tobacco flavoring shell to flavoring substance within the above range ensures sufficient flavor release, reduces swelling and pressure on the shell, and is beneficial to the long-term storage stability of the shell, thereby reducing the risk of breakage during production, transportation, and filter rod insertion.

[0113] This application also provides a system for the continuous production of tobacco flavorings, comprising:

[0114] A slurry preparation apparatus for preparing and storing the above-mentioned tobacco flavoring shell slurry;

[0115] A molding device is used to continuously mold the above-mentioned tobacco flavoring shell slurry into a polyhedral semi-shell to prepare an intermediate shell;

[0116] A filling device for injecting a fragrance substance into the aforementioned intermediate shell;

[0117] A sealing device is used to align and press together the two halves of the intermediate shell to seal them, in order to prepare tobacco flavorings;

[0118] A collection device for collecting tobacco flavorings.

[0119] An implantation device for implanting tobacco flavoring into a filter rod.

[0120] The aforementioned tobacco flavorings are used in cigarette filters. By applying less pressure, the outer shell ruptures to release the flavor, resulting in a more complete and even release. The flavoring substances diffuse and mix more quickly and evenly upon contact with the smoke, improving the uniformity and consistency of the smoking experience.

[0121] To make the objectives, technical solutions, and advantages of this application clearer and more concise, the following specific embodiments are used for illustration, but this application is by no means limited to these embodiments. The embodiments described below are merely preferred embodiments of this application and can be used to describe this application, but should not be construed as limiting the scope of this application. It should be noted that any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.

[0122] To better illustrate this application, the following description, in conjunction with embodiments, further explains the content of this application.

[0125] (2) Weigh out isomalt, maltodextrin, deionized water and nano silica according to the formula, mix them, heat and melt them at 160°C and homogenize them to obtain shell material slurry.

[0126] (3) Using precision micro-molding equipment, the slurry is injected into the icosahedral mold cavity (the diameter of the outer sphere is about 3.5 mm and the wall thickness is about 50 μm). After cooling and solidification, the mold is removed to obtain two hollow half-shells and prepare the middle shell.

[0127] (4) Use a micro-injection needle to inject peppermint oil into one half of the shell; align the other half of the shell with the shell and heat-press seal it for 100ms at 80℃ and 0.2MPa pressure to obtain a complete shell; the mass ratio of tobacco flavor shell to flavoring substance is 1:0.42.

[0128] (5) Performance testing: The shells prepared above were subjected to brittle fracture pressure, aroma retention rate and sensory evaluation tests. The brittle fracture pressure performance test was specifically conducted using a micro-force tester of model HT-2402 (range 0-50N, accuracy 0.01N), with a probe diameter of 2mm and a pressing speed of 5mm / min. The average value of 20 samples was taken.

[0129] The retention rate of aroma substances was determined by measuring the residual amount of key aroma components using gas chromatography-mass spectrometry (GC-MS) after accelerated aging for 30 days in a constant temperature and humidity chamber at 40°C and 75% relative humidity.

[0130] The sensory evaluation test was conducted by 10 trained tasters who conducted blind tests on the same type of cigarettes. The test was scored according to YC / T 497-2014 "Sensory Evaluation Method for Chinese Style Cigarettes" to assess the crushing sensation, aroma release speed, aroma richness and uniformity (out of 10 points).

[0131] Example 2

[0132] The preparation method of the shell in Example 2 is basically the same as that in Example 1. The difference is that the raw materials in Table 1 are different. Please see Table 1 for details.

[0133] (1) Provide the following raw materials by mass percentage: 70% sucrose, 20% gum arabic, 9.5% deionized water, and 0.5% glycerol.

[0134] (2) Weigh out the sucrose, gum arabic, deionized water and glycerin according to the formula, mix them, heat and melt them at 160°C and homogenize them to obtain shell material slurry.

[0135] (3) Using the template forming method, a half shell is formed and dried on a dodecahedral pit template to prepare the intermediate shell.

[0136] (4) Disperse 1.5 parts gellan gum in 98.5 parts citrus flavoring, heat to 80°C to activate and then cool to form a gel. Inject the citrus flavoring gel into one half of the shell, and wet the bonding surface of the other half of the shell with 50% ethanol aqueous solution and then press and seal it. Dry at room temperature to prepare the shell. The mass ratio of the tobacco flavoring shell to the flavoring substance is 1:0.54.

[0137] Examples 3 to 5

[0138] The preparation methods of the shells in Examples 3 to 5 are basically the same as those in Example 1, except that the raw materials in Table 1 are different. Please refer to Table 1 for details.

[0139] The other steps and conditions are the same as in Example 1.

[0140] Examples 6 to 8

[0141] The preparation methods of the shells in Examples 6 to 8 are basically the same as those in Example 1, except that the raw materials in Table 1 are different. Please refer to Table 1 for details.

[0142] The other steps and conditions are the same as in Example 1.

[0143] Comparative Example 1

[0144] Comparative Example 1 is a traditional carrageenan burst bead, specifically: a 3.5 mm diameter carrageenan spherical burst bead is prepared using conventional processes, and the inside is filled with peppermint essential oil as in Example 1.

[0145] Comparative Examples 2-3

[0146] The preparation methods of the shells in Comparative Examples 2 and 3 are basically the same as those in Example 1, except that the raw materials used in preparation are different. Please refer to Table 1 for details.

[0147] The other steps and conditions are the same as in Example 1.

[0148] Table 1

[0149]

[0150] Table 2

[0151]

[0152] Table 3

[0153]

[0154] The tobacco flavorings prepared in Examples 1 and 2 significantly outperformed traditional gelatin burst beads (Comparative Example 1) and simple solid candy balls (Comparative Example 3) in terms of brittleness, flavor retention, and sensory experience. The polyhedral structure ensured low and consistent brittleness pressure, the hollow structure enabled high-capacity encapsulation, and the brittle, glassy candy shell provided excellent barrier protection. The gel core further enhanced stability and release uniformity.

[0155] Examples 3-8 above demonstrate that high-performance tobacco flavorings can be successfully prepared when the mass ratio of brittle matrix material to molding stabilizer is within the range of (70-95):(4-25). Comparative Examples 2 and 3 show that once this range is exceeded, the product either loses its brittleness or cannot be molded at all, thus conversely proving the necessity and superiority of the formulation range of this application.

[0156] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0157] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
