Description

Technical Field

[0001] This invention belongs to the field of tobacco product maintenance technology, and relates to a cigar aroma-enhancing slow-release system and its preparation method, as well as a cigar maintenance method. Background Technology

[0002] As a high-end tobacco product, the taste, aroma, and aging process of cigars directly determine their quality. The cigar curing process is a core element affecting cigar quality, aiming to remove impurities, improve aroma harmony, and enhance combustion and smoking experience. Improperly cured or uncured cigars often have a spicy, ammonia-like, or grassy taste, resulting in a rough smoke texture and making it difficult to achieve the ideal smoking experience.

[0003] Current cigar preservation methods mainly rely on large-scale constant temperature and humidity humidifiers or natural aging. However, these methods have significant technical flaws and limitations. Large-scale humidifier preservation requires specialized equipment, occupies a large area, and is costly. It is only suitable for cigar collection and bulk preservation scenarios, and the aging process is lengthy, making it unsuitable for the preservation needs of small-batch cigars for home and retail use. Natural aging, on the other hand, requires a long period of 1-5 years, resulting in extremely high time costs. Furthermore, the aging effect is greatly affected by factors such as ambient temperature, humidity, and air circulation, leading to poor cigar quality stability and making standardized preservation difficult. Summary of the Invention

[0004] Therefore, it is necessary to provide a cigar aroma-enhancing slow-release system that can rapidly improve cigar quality and ensure high cigar quality stability, as well as its preparation method and cigar maintenance method.

[0005] In some embodiments, a cigar flavoring sustained-release system is provided, comprising flavoring liquid, sustained-release carrier and additives, wherein the sustained-release carrier comprises β-cyclodextrin, polyethylene glycol, sodium alginate and diatomaceous earth;

The components work synergistically to achieve a stable and slow-release of aroma without affecting the quality of the cigar itself. It can achieve controllable slow release for 30-180 days, and can quickly reduce the spiciness of the cigar and enhance its sweetness within 7-30 days, replacing long-term natural aging. The cigars treated with this system have high quality stability. Attached Figure Description

[0048] In this application, "room temperature" generally refers to 5℃~30℃, and more preferably 25±5℃.

[0049] In this application, "RH" refers to relative humidity, which is the percentage of water vapor content in the current air relative to the maximum saturation water content of the air at the same temperature.

[0050] Although cigarettes commonly use flavor capsules, filter beads, microcapsules, and slow-release filler to enhance the aroma and control the release of flavor, and cigarettes use humidifiers, aroma sticks, and external aroma boxes to enhance flavor, these slow-release flavor enhancers are unstable, prone to leakage and flavor transfer, and have a rapid release and short cycle. They are not compatible with the microenvironment of 18±2℃ / 65±5%RH in the cigar box. They cannot quickly mellow and improve the quality, cannot quickly reduce the spiciness of cigars, cannot enhance sweetness and woody aroma, and cannot replace long-term natural aging.

[0051] In some embodiments, a cigar flavoring sustained-release system is provided, comprising flavoring liquid, sustained-release carrier and additives, wherein the sustained-release carrier comprises β-cyclodextrin, polyethylene glycol, sodium alginate and diatomaceous earth;

[0052] By weight, the cigar flavoring and sustained-release system comprises 10 to 20 parts β-cyclodextrin, 5 to 10 parts polyethylene glycol, 2 to 5 parts sodium alginate, 20 to 40 parts diatomaceous earth, 1.5 to 18 parts flavoring liquid, and 0 to 11.5 parts additives.

[0053] Non-limitingly, β-cyclodextrin is used to encapsulate aroma molecules, enabling a slow release of aroma; polyethylene glycol enhances the formability and stability of the sustained-release agent; sodium alginate forms a breathable membrane to control the release rate; diatomaceous earth absorbs excess moisture, regulates the humidity inside the cigar box, and simultaneously enhances the breathability of the sustained-release agent to prevent leakage. These four components synergistically form a gradient sustained-release system, ensuring uniform and long-lasting aroma release. Through the synergistic effect of carriers such as β-cyclodextrin, sodium alginate, and diatomaceous earth, a gradient sustained-release system is constructed, adapted to the microenvironment of the cigar box at 18±2℃ and 65±5%RH, achieving stable sustained release for 30–180 days, controllable aroma concentration, no leakage or flavor transfer, and a shelf life of over 12 months for the sustained-release agent.

[0054] Using this cigar conditioning and corrosion inhibitor to condition cigars for 7 days will show results, and a high-quality aging effect will be achieved in 30 days. The spiciness will be reduced by ≥30%, and the sweetness and woody aroma will be increased by ≥50%. This will significantly shorten the aging cycle of cigars (from 1-5 years to 1-6 months), reduce maintenance costs, and achieve standardized optimization of cigar taste.

[0055] The provided cigar care corrosion inhibitor can enhance the aroma of cigars, breaking through the existing methods that focus on "moisturizing and temperature control" to quickly optimize the taste of cigars.

[0056] Understandably, the provided cigar flavoring sustained-release system may contain 10 to 20 parts of β-cyclodextrin by weight, or 13 to 16 parts, for example, 10, 12, 14, 16, 18, 20 parts, or any range of the two aforementioned values.

[0057] Understandably, the provided cigar flavor-enhancing sustained-release system may contain 5 to 10 parts, or 7 to 8 parts, of polyethylene glycol by weight, for example, 5, 6, 7, 8, 9, or 10 parts, or any combination of the aforementioned values. In some embodiments, the number-average molecular weight of the polyethylene glycol is 3000 g / mol to 8000 g / mol.

[0058] Understandably, the provided cigar flavor-enhancing slow-release system may contain 2 to 5 parts sodium alginate by weight, or 3 to 4 parts, for example, 2, 3, 4, 5 parts, or any range of the aforementioned two values.

[0059] Understandably, the provided cigar flavoring and slow-release system may contain 20 to 40 parts of diatomaceous earth by weight, or 25 to 35 parts, for example, 20, 25, 30, 35, or 40 parts, or any range of the aforementioned two values.

[0060] Understandably, the provided cigar flavoring and slow-release system may contain 1.5 to 18 parts of flavor liquid, or 9 to 12 parts, for example, 1.5, 3, 6, 9, 12, 15, 18 parts, or any range of the two aforementioned values.

[0061] Understandably, the provided cigar flavoring and sustained-release system may contain 0 to 11.5 parts of additives by weight, or 6 to 8 parts, for example, 0, 1.5, 3, 4.5, 6, 7.5, 8, 9, 10.5, 11.5, etc., or any range of the aforementioned two values.

[0062] In some embodiments, the fragrance liquid contains at least two of agarwood, sandalwood, lychee honey, and lemongrass. In some embodiments, the provided cigar aroma-enhancing sustained-release system contains at least two of the following components in parts by weight: 2 to 5 parts agarwood essential oil, 1 to 3 parts sandalwood essential oil, 3 to 8 parts lychee honey extract, and 0.5 to 2 parts lemongrass essential oil.

[0063] The flavoring liquid used creates a complex Chinese aroma, distinct from the vanilla aroma of Western cigars such as Cuban and Dominican cigars. Chinese cigars tend to have a warm, sweet, and lingering flavor, and the flavoring liquid used is highly compatible with the flavor requirements of Chinese cigars, featuring a rich agarwood aroma, a long-lasting sandalwood aroma, a sweet lychee honey aroma, and a refreshing lemongrass aroma.

[0064] Glycerin and glycerol are used to moisturize and maintain the moisture of the slow-release agent, while also helping to regulate the humidity inside the box to meet the humidity requirements of cigar preservation.

[0065] In some embodiments, the antioxidant includes vitamin E, etc. Non-limitingly, the antioxidant is used to prevent the essential oil from oxidizing and deteriorating, and to extend the shelf life and release period of the sustained-release agent.

[0066] The provided cigar aroma-enhancing sustained-release system is simple to prepare, low in cost, and can be mass-produced; the aroma-enhancing process is easy to operate, requires no professional equipment, and can be used directly by consumers, making it easy to promote and apply; the sustained-release module is detachable and replaceable, and the small box is reusable, making it more environmentally friendly.

[0067] In some embodiments, the provided cigar flavoring sustained-release system, by weight, comprises 3 to 8 parts glycerol, 1 to 3 parts glycerol, and 0.1 to 0.5 parts antioxidant.

[0068] In some embodiments, the provided cigar flavoring sustained-release system includes antioxidants comprising one or more of vitamin E, tea polyphenols, and grape seed extract.

[0069] In some embodiments, a method for preparing the aforementioned cigar flavor sustained-release system is provided, comprising the following steps:

[0070] The sustained-release carrier is prepared by mixing the β-cyclodextrin, the polyethylene glycol, the sodium alginate, and the diatomaceous earth.

[0071] The sustained-release carrier, the flavor liquid, and the additives are stirred and mixed, granulated, dried, and sterilized to prepare the cigar flavor sustained-release system.

[0072] In some embodiments, the method for preparing the cigar flavor sustained-release system involves stirring at a speed of 500 r / min to 800 r / min for a stirring time of 30 min to 60 min.

[0073] In some embodiments, the granulation method for preparing the cigar flavor sustained-release system yields particles with a particle size of 2mm to 5mm.

[0074] In some embodiments, the preparation method of the provided cigar flavor sustained-release system involves drying at a temperature of 50°C to 60°C for 2 hours to 4 hours.

[0075] In some embodiments, the preparation method of the provided cigar flavor sustained-release system uses ultraviolet sterilization or ethylene oxide sterilization for a sterilization time of 15 min to 20 min.

[0076] In some embodiments, the method for preparing the cigar aroma sustained-release system includes the following steps: stirring the aroma liquid at 40°C to 60°C for 15 to 30 minutes at a stirring speed of 300 r / min to 500 r / min.

[0077] In some embodiments, a cigar care method is provided, comprising the following steps:

[0078] The cigars and the aforementioned cigar aroma-slow-release system were left to stand in an environment with a temperature of 16℃~20℃ and a relative humidity of 60%~70%.

[0079] In some embodiments, the provided cigar preservation method involves placing the cigar and the cigar aroma-releasing system in a small box, controlling the temperature inside the small box to be 18±2℃ and the humidity to be 65±5%RH, and then letting it stand.

[0080] In some implementations, the provided cigar preservation method involves a resting period of at least 7 days.

[0081] In some embodiments, the provided cigar care method includes a small box comprising a box body 1 and a box lid 2, wherein the box body and the box lid are connected by a hinge 5.

[0082] The box body 1 is provided with a cigar storage slot 9, a slow-release granule placement hole 7, a hygrometer placement area 6, and a humidifier ventilation slot 8. An airtight strip 4 is provided on the area of ​​the box body 1 that contacts the box lid 2. The opening of the slow-release granule placement hole 7 is covered with a breathable mesh plug.

[0083] Box 1, as the main space for carrying cigars, adopts a regular rectangular structure, providing an installation benchmark and physical protection for the internal components, and is the structural foundation of the entire box.

[0084] The lid 2 and the box body 1 are opened and closed by hinge 5, which, together with the box body, forms a closed microenvironment to protect the cigars from external dust and odors, while also providing a mating surface for the airtight structure.

[0085] The airtight strip 4 is installed at the joint edge of the box body 1 and the box lid 2. It is usually made of wood and can effectively improve the sealing performance after the box is closed, reduce humidity fluctuations, and maintain a stable internal moisture environment.

[0086] The hinge 5 is the hardware that connects the box body 1 and the box cover 2. It adopts a symmetrical double hinge structure to ensure that the box cover opens and closes smoothly and is not easy to loosen. At the same time, it maintains the alignment of the box cover and the box body, and assists the airtight strip to achieve a seal.

[0087] The hygrometer 6 is a high-precision humidity monitoring component integrated inside the box 1. It can display the humidity inside the box in real time, helping users monitor the humidification status and ensure that the humidity of cigar storage is maintained in the ideal range of 65%-75%.

[0088] In some embodiments, 4-8 slow-release particle placement holes are provided inside the cigar box. The opening of the slow-release particle placement hole 7 is covered with a breathable mesh plug. The breathable mesh plug has several breathable mesh holes with a diameter of 0.1mm to 0.5mm. The breathable mesh plug is opened, the aroma and humectant slow-release particles are placed into the holes, and then the mesh plug is closed. The pore structure of the mesh plug can achieve slow and even release of aroma and humectant components, while preventing particles from scattering and contaminating the cigar.

[0089] The humidifier ventilation slot 8 provides a gas exchange channel for the humidification system inside the box, and works with the humidification device to achieve slow release and circulation of moisture, avoiding excessively high or low humidity inside the box, and ensuring a stable aging environment for cigars.

[0090] The cigar slot 9 is a specially designed groove structure inside the box that can accommodate the size of multiple cigars, fix the position of the cigars, prevent them from rolling or bumping during transportation or storage, and protect the appearance and structural integrity of the cigars.

[0091] In some embodiments, the box body 1 is provided with a finger position 3, which is a concave structure on the outside of the box body 1, so that the user can apply force when opening and closing the box lid 2, improving the ease of operation and avoiding wear caused by directly pressing the box lid.

[0092] Place the cigars to be cured into a small cigar box containing the aroma-releasing agent, and tighten the lid to ensure a good seal. Control the environmental parameters inside the box as follows: temperature 18±2℃, humidity 65±5%RH. These parameters are suitable for the optimal microenvironment for cigar curing and match the slow-release characteristics of the agent to ensure stable aroma release. Place the sealed cigar box in a cool, dark, and dry place for aroma-releasing. The release period is 30–180 days (adjusted according to the quality requirements of the cigars; 30–60 days for ordinary cigars and 90–180 days for high-end cigars). During the release process, the aroma concentration follows a pattern of "low at the beginning, stable in the middle, and slow decrease at the end." The first 7 days are the aroma adaptation period, during which the aroma is released slowly. The 10–120 days are the stable release period, during which the aroma concentration is uniform. After 120 days, the aroma gradually weakens, and the aroma-releasing agent module can be replaced at this time.

[0093] This small box achieves constant humidity, airtightness, and protection during cigar storage. The combination of airtight strips, hinges, box body, and lid ensures a sealed environment; the hygrometer, slow-release granule placement hole, and breathable mesh plug create an active humidity and aroma regulation system; and details such as the finger rest and cigar slot balance ease of use with physical protection for the cigars.

[0094] After 7–30 days of aroma conditioning, the spiciness of the cigar decreases by ≥30%, the sweetness increases by ≥50%, and the woody aroma increases by ≥50%. Ammonia and off-flavors are significantly reduced, resulting in a taste close to that of a cigar aged naturally for 3–5 years. After aroma conditioning, the cigar is ready to eat immediately upon opening the box; no additional aging process is required.

[0095] This application enables the aroma preservation of cigars in a small box. The cigar aroma preservation slow-release system can release aromas that match Chinese cigars, breaking the limitations of existing cigar preservation methods that rely on large humidifiers and natural aging. It achieves "preservation in a small box, ready to eat upon opening", suitable for home use, retail, travel and other scenarios, filling the industry gap in small box cigar preservation technology.

[0096] The following are specific embodiments. They are intended to provide a more detailed description of this application to help those skilled in the art and researchers better understand it. The technical conditions described do not constitute any limitation on this application. Any modifications made within the scope of the claims of this application are protected by the claims.

[0097] Unless otherwise stated, all raw materials and reagents used in the following examples are commercially available or can be prepared by known methods. Experimental methods not specifying particular conditions in the examples were performed under conventional conditions, such as those described in literature, books, or methods recommended by the manufacturer.

[0098] High-end Chinese cigars are hand-rolled using carefully selected tobacco leaves that have been aged for many years. They have a rich aroma and require low humidity and low temperature for long-term slow-release maintenance to optimize their flavor. Mid-range Chinese cigars are semi-mechanized and produced using a blend of medium-grade tobacco leaves. They have a moderate level of off-flavors and are suitable for higher humidity and medium-term aging. Regular Chinese cigars use conventional machine-made tobacco leaves as raw materials. They have a stronger fire and off-flavors when they leave the factory and are suitable for short-term aging at normal temperature and humidity. Based on the different characteristics of the raw materials and taste of the three types of cigars, three different slow-release aging systems with different components are specially formulated.

[0141] Comparative Example 4

[0142] This comparative example provides a Chinese-style aroma-enhancing slow-release agent for cigar boxes. The formula and preparation method are similar to those in Example 1.

[0143] The same process as in Example 1 was used to flavor and condition ordinary Chinese cigars.

[0144] Test case

[0145] The aroma conditioning process for each embodiment and comparative example is as described above. Among them, Example 1 and Comparative Examples 1 to 4 used unaged fresh cigar samples from the same batch, grade, and origin, with consistent initial quality.

[0146] The traditional cigar aging process is as follows: Take fresh, unaged cigar samples of the same batch, grade, and origin as in Example 1, and keep them in a static environment for 30 days at a temperature of 18°C, humidity of 65%RH, in the dark, well-ventilated, dust-free, and odor-free conditions, allowing the tobacco leaves to slowly metabolize and complete the spontaneous aging process.

[0147] After the aging period was completed, the cigars' appearance, moisture content, aroma quality, and flavor profile were tested. The specific testing methods and results are as follows:

[0148] (1) Appearance inspection

[0149] The color, smoothness, and integrity of the cigar wrapper were inspected using visual appearance analysis.

[0150] Tests showed that the cigar wrappers, after being maintained, were evenly oily and free of wrinkles and mold.

[0151] (2) Moisture content test

[0152] The moisture content of cured cigars was determined using the oven drying method specified in YC / T 31-2019.

[0153] Tests showed that the moisture content of the cigars stabilized within the optimal range of 11% to 13% after maintenance.

[0154] (3) Aroma quality and taste layering test

[0155] The aroma quality and flavor profile of aged cigars were evaluated using the professional blind sensory evaluation method (YC / T 138-2019). A panel of 10 certified tobacco sensory evaluators conducted blind tastings and scored the cigars, with the average score used as the valid data. Unaged fresh cigars were used as a blank baseline sample, with baseline scores set as follows: 100 points for spiciness, 0 points for sweetness, 0 points for woody notes, and 100 points for off-flavors. Higher scores for spiciness and off-flavors indicated lower quality, while higher scores for sweetness and woody notes indicated higher quality. The definitions of each indicator are as follows:

[0156] Spiciness: Evaluate the spicy and irritating sensation in the mouth, throat, and nasal cavity during inhalation, and score according to the intensity of stimulation (0 points for no stimulation, 100 points for extremely strong stimulation).

[0157] Sweetness: Evaluate the sweetness, smoothness, and mouthfeel of the smoke (0 points for no sweetness, 100 points for rich and sweetness).

[0158] Woody aroma: Evaluate the concentration and comfort of pure woody aroma in the smoke (0 points for no woody aroma, 100 points for pure and rich woody aroma).

[0159] Off-odors: The focus is on determining the degree of residual unpleasant odors such as ammonia, green off-odors, and pungent odors (0 points for no off-odors, 100 points for strong off-odors).

[0160] All improvement / deterioration indicators in this experiment are based on a blank benchmark sample and are calculated using the following formula:

[0161] Spiciness reduction = (Base spiciness score - Spiciness score after maintenance) ÷ Baseline spiciness score × 100%;

[0162] Increase in sweetness / moisture level = (Sweetness / moisture score after maintenance - Baseline sweetness / moisture score) ÷ Maximum score × 100%;

[0163] Increase in woody scent = (Woody scent score after maintenance - Baseline woody scent score) ÷ Maximum score × 100%.

[0164] The improvement of impurities is determined by the evaluation personnel and is divided into five levels according to the degree of impurity residue: basically eliminated, slightly reduced, small amount of residue, obvious residue, and large amount of residue.

[0165] The test results are shown in Table 1.

[0166] (4) Method for determining the equivalent natural aging period

[0167] Using standard cigar samples that have undergone traditional natural aging for 1 year, 1.5 years, 2 years, 3 years, and less than 6 months as control samples, blind evaluations were conducted under uniform environmental conditions. The overall sensory quality (spiciness, sweetness, woodiness, and off-flavors) of each group of aged cigars was matched with the standard samples of different natural aging periods. The aging time with consistent matching was taken as the equivalent natural aging period for that group. The test results are shown in Table 1.

[0168] Table 1

[0169]

[0170] As shown in Table 1 above, the cigar aroma-enhancing slow-release system provided in this application can rapidly reduce the spiciness of cigars and enhance their sweetness. After conditioning, the off-flavors of the cigars are basically eliminated, and the aroma is pure and full, with significantly improved sweetness and smoke delicacy, resulting in a taste close to that of a 3-year naturally aged cigar. In contrast, in Comparative Examples 1 to 4, removing any of the slow-release carriers—β-cyclodextrin, polyethylene glycol, or sodium alginate—or replacing all functional flavoring ingredients significantly reduced the encapsulation, aroma control, and aroma enhancement performance of the slow-release system, and the improvement in various sensory indicators were far lower than those in the embodiments of this application. The traditional 30-day natural conditioning had a negligible effect on improving the taste of cigars. The cigar conditioning method provided in this application, when used to condition cigars, resulted in a significantly superior taste profile compared to traditional conditioning and the comparative examples. This demonstrates that the components of the cigar aroma-enhancing slow-release system provided in this application work synergistically to achieve the technical effect of several years of natural aging in a short-cycle conditioning process, replacing long-term natural aging.

[0171] (5) Testing the stability of cigar quality

[0172] Batch consistency was verified by using the coefficient of variation (CV) of parallel samples, and long-term stability was verified by retesting after 90 days of sealed storage at room temperature.

[0173] The test results show that when using the cigar aroma-enhancing slow-release system provided in this application for cigar preservation, the sample batch variation coefficient is ≤1.32%, and the batch quality difference is minimal; the sensory index decay rate after 90 days of long-term storage is ≤2.3%, and the aroma, taste and moisture content are stable with no obvious deterioration. Compared with traditional preservation and comparative samples, the quality stability is significantly improved.
