[0036] The first aspect of this application provides a method for preparing a cigar roll adhesive, comprising the following steps:

[0037] S1. Lychee powder, agarwood powder, and sandalwood powder are mixed by stirring to obtain a first compound fragrance powder; the mass ratio of lychee powder to agarwood powder and sandalwood powder is (60~80):(10~20):(10~30); lychee powder includes lychee peel powder and lychee pulp powder; S2. The first compound fragrance powder is mixed with water, steamed in a water bath, pressed into incense blocks, dried, and ground to obtain a second compound fragrance powder; the steaming temperature is 85℃ to 95℃; S3. Under stirring conditions, the second compound fragrance powder is added to water and stirred until there is no dry powder, sodium carboxymethyl cellulose is added, and stirred until the sodium carboxymethyl cellulose dissolves to obtain a glue solution; the mass ratio of the second compound fragrance powder to water is 1:(1~3); the mass ratio of sodium carboxymethyl cellulose to the second compound fragrance powder is 1:(3~5); S4. The glue solution is sealed and aged at 25℃ to 35℃ for 12h to 24h to obtain a cigar rolling adhesive. Specifically, the mass ratio of lychee powder to agarwood powder and sandalwood powder includes, but is not limited to, 70:15:20, 80:20:30, 60:10:10, 70:10:30, 80:20:10, or any two of the aforementioned ranges. Specifically, the temperature for steaming includes, but is not limited to, 85℃, 87℃, 89℃, 91℃, 93℃, 95℃, or any two of the aforementioned ranges. Specifically, the mass ratio of the second compound fragrance powder to water includes, but is not limited to, 1:1, 1:1.5, 1:2, 1:2.5, 1:3, or any two of the aforementioned ranges. Specifically, the mass ratio of sodium carboxymethyl cellulose to the second compound fragrance powder includes, but is not limited to, 1:3, 1:3.5, 1:4, 1:4.5, 1:5, or any two of the aforementioned ranges. Specifically, the aging temperature includes, but is not limited to, 25℃, 27℃, 29℃, 31℃, 33℃, 35℃, or any two of the aforementioned ranges. Specifically, the aging time includes, but is not limited to: 12h, 14h, 16h, 18h, 20h, 22h, 24h or any range between the two mentioned above.

[0038] This application prepares a cigar rolling binder (adhesive) by compounding lychee powder with agarwood powder, sandalwood powder with sodium carboxymethyl cellulose, combining this with a low-temperature preparation process including steaming to prepare a second composite flavoring powder and aging the adhesive solution. This binder is widely applicable to the rolling of various cigars and other cigarettes. On one hand, the cigar rolling binder prepared in this application has virtually no odor when burning, burns evenly and smoothly without flameout or flickering, and produces clean, compact, and stable ash that is not easily shed, exhibiting excellent ash retention and thus improving the cleanliness of the cigarette during smoking. On the other hand, the natural materials such as lychee powder, sandalwood powder, and agarwood powder in the first composite flavoring powder impart a sweet fruity aroma and an elegant woody fragrance when burning. The fruity aroma is fresh and natural, not cloyingly sweet, while the woody aroma is mellow, lingering, and not pungent. The two aromas blend well, providing smokers with a unique aroma experience of "sweetness upon entry and elegant aftertaste." Therefore, the cigar rolling binder of this application has excellent combustion performance. Meanwhile, the lychee peel powder in lychee powder is rich in pectin, which can synergistically work with sodium carboxymethyl cellulose to enhance the adhesive strength of the binder. This improves the adhesion between the wrapper and the filler, reducing the likelihood of white marks on the wrapper and bursting or deformation during rolling, thus increasing the success rate of cigar rolling. Furthermore, the addition of these natural materials can enhance the antibacterial properties of the cigar, improving the local microenvironment of the tobacco and aiding in the natural aging process. During long-term storage, it can continuously nourish the tobacco, slowly reducing its dryness and off-flavors, and promoting a richer, smoother taste. In addition, the natural ingredients also have a moisturizing effect, reducing moisture loss during storage, preventing the tobacco from drying out and developing a different flavor, and extending its shelf life.

[0039] Compared to directly heating the first compound flavor powder, steaming within the temperature range of this application reduces the chance of scorching during heating, minimizing aroma loss, and ensuring the powder is fully cooked and releases its aroma. Furthermore, the aging process eliminates air bubbles in the adhesive, allowing the aroma to fully integrate and disperse evenly with sodium carboxymethyl cellulose in the binder. Therefore, by introducing the above process and controlling the corresponding parameters within the range of this application, it is beneficial to further enhance the aroma profile of the cigar rolling binder and form a binder system with good uniformity.

[0040] In this application, by adjusting the mass ratio of lychee powder, agarwood powder, and sandalwood powder, as well as the mass ratio of sodium carboxymethyl cellulose to the second compound fragrance powder within the above-mentioned range, the adhesive effect of the binder on the cigar rolling process can be optimized. At the same time, it is also beneficial to further harmonize the fusion of fruit and wood aromas and the concentration of aroma, without masking the original aroma of the tobacco, neutralizing the dryness, improving the overall purity of the cigar's aroma, and enhancing the smoker's overall experience.

[0041] Therefore, the cigar rolling adhesive prepared according to the preparation method of this application has the following characteristics: (1) excellent combustion performance, unique aroma layers and high cleanliness of smoking, which is conducive to improving the overall experience of the smoker; (2) excellent adhesion performance, which can improve the forming rate of cigar rolling and reduce the probability of white marks left on the wrapper; (3) can assist the natural aging of tobacco materials and extend the shelf life of cigarettes; (4) it is compatible with various rolling methods such as machine rolling, hand rolling, and semi-hand rolling, reducing the difficulty of production operation.

[0042] In this application, the prepared cigar roll adhesive contains natural ingredients and therefore needs to be sealed and stored at 15°C to 25°C, with a shelf life of 90 to 120 days.

The dried lychee peel and dried lychee pulp can be obtained by purchase or by removing the stems and pits from fresh lychees and then sun-drying them.

[0050] This application does not impose any particular limitation on the mass ratio of lychee peel powder to lychee pulp powder in lychee powder, as long as the purpose of this application can be achieved. For example, the mass ratio of lychee peel powder to lychee pulp powder can be 2:8 to 4:6.

[0051] This application does not impose any particular restrictions on the variety of lychee, as long as it can achieve the purpose of this application. For example, lychee powder prepared from Meishan "Dongpo Red" lychee can be used.

[0052] The sandalwood powder in this application can be obtained by purchasing or by grinding the heartwood of white sandalwood (East Indian sandalwood).

[0053] The agarwood powder in this application can be purchased. Sandalwood powder and agarwood powder of different fineness can be obtained by grinding.

[0054] Sodium carboxymethyl cellulose in this application is commercially available. In some embodiments, in step S2, the grinding temperature is 30°C to 40°C, and the resulting second composite fragrance powder has a fineness of 120 mesh to 150 mesh. By controlling the grinding temperature within the above range, the volatilization of the aroma in the first fragrance powder during preparation can be reduced; by controlling the fineness of the second composite fragrance powder within the above range, it is not only beneficial to the release of fragrance, but also beneficial to improve the subsequent integration of the second fragrance powder with sodium carboxymethyl cellulose, thereby reducing the graininess and improving the fineness of the adhesive, laying the foundation for the subsequent preparation of an adhesive with rich fragrance and good adhesion. Specifically, the grinding temperature includes, but is not limited to: 30°C, 32°C, 34°C, 36°C, 38°C, 40°C, or any two of the above. Specifically, the fineness of the second composite fragrance powder includes, but is not limited to: 120 mesh, 126 mesh, 132 mesh, 138 mesh, 144 mesh, 150 mesh, or any two of the above.

The stirring speed was 300r / min and the stirring time was 25min to obtain the first compound fragrance powder. The mass ratio of lychee powder to agarwood powder and sandalwood powder was 80:20:30.

[0082] S2. Mix 5200g of the first compound incense powder with 6355g of water (the mass ratio of the first compound incense powder to water is 45:55), and steam it at 91℃ for 45 minutes. During the steaming process, keep the mixture mechanically stirred to prevent clumping. After steaming, press it into incense blocks with dimensions of 4cm×3cm×1.5cm. Transfer the incense blocks to a dust-free clean environment at 25℃ and 50% humidity and let them air dry for 72 hours. The moisture content of the dried incense blocks is 4.9%. Grind the dried incense blocks in batches at 35℃ until the fineness is 150 mesh to obtain the second compound incense powder, and store it in a sealed container.

[0083] S3. Under stirring conditions of 580 r / min, add 5200 g of the second compound fragrance powder to a mixing tank containing 8000 g of water and stir for 20 min until no dry powder remains. Add tobacco-grade sodium carboxymethyl cellulose in two portions, with the same mass of sodium carboxymethyl cellulose added each time. Stir for 5 minutes after each addition before adding the next portion of sodium carboxymethyl cellulose. Stir until the sodium carboxymethyl cellulose dissolves to obtain a colloid. Filter the colloid twice using an automated filtration device (200 mesh). The mass ratio of the second compound fragrance powder to water is 1:1.54; the mass ratio of sodium carboxymethyl cellulose to the second compound fragrance powder is 1:4; the amount of sodium carboxymethyl cellulose added at one time is 650 g; and the total amount added is 1300 g.

[0084] S4. Seal the adhesive solution and age it for 24 hours in a constant temperature crystallization environment at 25°C to obtain the cigar rolling adhesive. Comparative Example 1:

[0085] Except for the fact that the raw materials in step S1 do not include lychee powder, the rest is the same as in Example 1.

[0086] Comparative Example 2:

[0087] Except for the fact that the raw materials in step S1 do not include agarwood powder and sandalwood powder, the rest is the same as in Example 1.

[0088] Comparative Example 3:

[0089] Preparation of the first compound fragrance powder: same as in Example 1.

[0090] Add 200g of the first compound flavor powder and 10g of carboxymethyl cellulose to 800g of water, stir at 500r / min for 20min, filter twice with a 200-mesh sterile filter cloth to remove larger impurities and powder lumps to obtain the cigar rolling binder.

[0091] Take the cigar rolling binder prepared in the example or comparative example, and use it on 10 Great Wall Range Rover No. 3 Classic cigars, with 8g of binder used on each cigar. Take 5 of these cigars for sensory evaluation, and prepare cigars of the same specifications as a control. The specific method is as follows:

[0092] Table 1

[0093]

[0094] The sensory quality of smoked cigars was evaluated using a rating system.

[0095] This evaluation standard uses a 10-point scale and comprises 9 core evaluation indicators. It takes into account the characteristics of the cigar rolling adhesive used in this application, and is tailored to the needs of cigar rolling and smoking experiences. The specific scoring criteria are as follows:

[0096] Table 2

[0097]

[0098] The overall performance of cigars is evaluated using a total score. A total score of 80 or above is considered excellent, 60-80 is acceptable, and less than 60 is unacceptable.

[0099] In Example 1, the test evaluation results of the cigar were as follows: total score of 85 points (excellent), including 9.5 points for white mark retention, 9.3 points for viscosity compatibility, 9.2 points for flavor, 10 points for off-flavors, 9.8 points for strength, 9.3 points for aftertaste, 9.5 points for irritation, 9.2 points for harmony, and 9.2 points for ash. The cigar had a fine and particle-free gum, a natural and blended aroma, no cracking during rolling, even burning, and white ash retention.

[0100] In Example 2, the test evaluation results of the cigar were as follows: total score of 81.8 points (excellent), including 9.5 points for white mark retention, 9.0 points for viscosity compatibility, 8.8 points for flavor, 9.5 points for off-flavors, 9.0 points for strength, 8.9 points for aftertaste, 9.5 points for irritation, 8.8 points for harmony, and 8.8 points for ash. The sizing was uniform, the aroma was stable, the hand-rolling was smooth and non-sticky, the cigarette was well-formed, and the combustion performance was good.

[0101] In Example 3, the test evaluation results of the cigar were as follows: total score of 80.3 points (excellent), including 9.1 points for white mark retention, 9.0 points for viscosity compatibility, 9.0 points for taste, 9.5 points for off-flavors, 8.6 points for strength, 8.8 points for aftertaste, 8.9 points for irritation, 8.7 points for harmony, and 8.7 points for ash. The viscosity of the sizing solution was stable, compatible with the machine-made cigar production line, with no sticking to the rollers or cracking at the mouth, and the aroma blended well with the natural aroma of the cigar.

[0102] In Comparative Example 1, the cigar's test evaluation results were as follows: total score 58 points (unqualified), including 6.0 points for white mark retention, 7.5 points for viscosity compatibility, 5.8 points for taste (no sweetness or layering), 6.0 points for off-flavors, 7.5 points for strength, 6.2 points for aftertaste (no lychee fruit aroma, only a single sandalwood aroma, slightly monotonous), 6.0 points for irritation, 5.5 points for harmony (the woody aroma and the tobacco aroma are not harmonious), and 7.5 points for ash. The gum liquid lacked the color of lychee, the aroma was monotonous, and the taste of the cigarette after rolling was dry.

[0103] In Comparative Example 2, the cigar's test evaluation results were as follows: total score 55.8 points (unqualified), including 5.5 points for white residue, 7.3 points for viscosity compatibility, 5.2 points for flavor (poor layering, sweetness masking the natural aroma of the tobacco), 6.5 points for off-flavors (only lychee sweetness, no elegant aroma, obvious sweetness), 7.0 points for strength, 5.5 points for aftertaste (sweetness lingering, no aftertaste), 6.8 points for irritation, 5.0 points for harmony (fruity aroma clashing with the natural aroma of the tobacco), and 7.0 points for ash. The cigar's gum was prominently sweet, had a slight burnt smell after burning, and had poor ash retention.

[0104] In Comparative Example 3, the cigar's test evaluation results were as follows: total score 51.3 points (unqualified), including 5.0 points for white residue, 6.2 points for viscosity compatibility (uneven glue, easy to burst), 4.8 points for taste (no layering, raw material taste), 6.0 points for off-flavors (raw and astringent off-flavors), 6.8 points for strength, 4.5 points for aftertaste (raw and astringent residue), 7.2 points for irritation, 4.8 points for harmony (aroma not released, weak fruit and wood aromas, raw and astringent taste), and 6.0 points for ash (uneven burning); the glue contained undissolved particles, resulting in poor shaping and the inability to release aroma properly.

[0105] As can be seen from Examples 1 to 3 and Comparative Examples 1 to 3, the adhesives prepared in the examples all meet the high-quality standard, proving that the preparation method of this application is scientific and feasible and suitable for different scales of production. Comparative Example 1 lacks the core raw material of lychee powder, Comparative Example 2 lacks the key raw materials of agarwood powder and sandalwood powder, and Comparative Example 3 did not undergo the key processes of water-bath steaming and aging, and all of them failed to meet the qualified standard. This fully verifies the core technical advantages of the preparation method of this application. The prepared adhesive can be used for the production of cigars of different scales, and the cigars obtained have better overall performance.

[0106] The cigar rolling adhesive in the embodiments has the following advantages:

[0107] I. Enhance the sensory experience of the smoker, specifically including: (1) Aroma: The sweet and refreshing aroma of lychee blends naturally with the elegant fragrance of sandalwood, resulting in a pure and authentic flavor without any off-flavors (single item score ≥ 9.0); (2) Aftertaste and Harmony: Pure and comfortable, with a refreshing and sweet aftertaste, and the adhesive is highly integrated with the cigar's natural aroma (total score ≥ 88 points); (3) Room Aroma and Combustion: Even combustion, dense ash, white ash, and a comfortable room aroma without any pungent smell. Thus, the cigar rolling adhesive of this application effectively reduces the generation of off-flavors and impurities, giving high-end Chinese cigars a unique lychee flavor, which can meet the needs of high-end customers for flavor levels.

[0108] II. Optimization of Appearance Quality: Specifically including: (1) Transparency and Gloss: The adhesive is transparent, leaves no white marks after drying, and the wrapper has a uniform and oily sheen (single item score ≥ 8.7); (2) Ash Performance: No black smoke is produced when burning, the ash is fine and does not contaminate the wrapper. Thus, the cigar rolling adhesive of this application effectively solves the problem of white marks left on the wrapper, improves the overall aesthetics of the cigar, and meets the appearance standards of high-end products.

[0109] III. Improved Process Adaptability: Specifically, this includes: (1) Moderate viscosity, smooth application, no sticking to rollers, no bursting, suitable for both manual and machine rolling; (2) Stable forming: flexible film formation, strong adhesion, and rolling efficiency can be increased by more than 30%. Traditional single sodium carboxymethyl cellulose adhesive is easily affected by temperature and humidity, static storage, and open-top operation, resulting in viscosity fluctuations. It has problems such as uneven viscosity of the adhesive, layering and skin formation, unstable adhesion, and easy sticking to rollers, which can easily cause bursting, white marks, and poor forming in cigar rolling, making it difficult to adapt to mass production. Therefore, the cigar rolling adhesive of this application is conducive to solving the above problems of sodium carboxymethyl cellulose adhesive, reducing the difficulty of rolling, and adapting to the dual needs of large-scale production and high-end manual rolling.

[0110] IV. Enhance safety and storage performance, specifically including: (1) Natural and additive-free: mainly natural raw materials, no preservatives or chemical additives, safe and non-irritating to smoke; (2) Natural antibacterial: lychee and agarwood components have antibacterial properties, which help cigars mature.

[0111] Therefore, the cigar rolling adhesive of this application conforms to the modern health consumption trend, helps to extend the cigar maintenance cycle, reduce storage losses, and improve the quality of the product throughout its entire life cycle.

[0112] Therefore, this application, through the compounding of lychee, agarwood, sandalwood, and carboxymethyl cellulose, combined with water-steaming and aging processes, systematically solves the core technical pain points of existing cigar rolling adhesives, such as off-flavors, white marks, process compatibility, and safe storage. It achieves four major technical effects: upgraded sensory experience, optimized appearance quality, enhanced process compatibility, and improved safe storage. This provides crucial technical support and product assurance for the quality improvement and brand differentiation of high-end Chinese cigars. The cigar rolling adhesive of this application can simultaneously improve flavor, appearance, process, and safety, providing a core auxiliary material solution for high-end Chinese cigars.

[0113] 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.

[0114] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
