Description

Technical Field

[0001] This invention belongs to the field of cigarette technology, specifically, it relates to a flavoring granule for cigarettes, its preparation method and application. Background Technology

[0002] Sensory quality is one of the core indicators for evaluating the quality of tobacco products, and the richness, harmony, and persistence of aroma are key factors determining sensory quality. To improve the flavor of tobacco products and enhance the smoking experience, adding flavorings and fragrances during tobacco processing has become a standard technique in the industry. Among these, flavoring granules for tobacco, as a novel form of flavoring, have been widely used in cigarette production in recent years, particularly in the development of menthol cigarettes, slim cigarettes, and medium-length cigarettes, due to their advantages such as the ability to carry flavorings, control the release rate, and improve the taste of smoke.

[0003] In existing technologies, the preparation of flavor-carrying granules for tobacco mainly employs the following methods:

[0004] The first method is direct adsorption. This involves using porous solid materials such as diatomaceous earth, activated carbon, or porous starch as a carrier to physically adsorb liquid flavorings into the carrier's pores. However, flavor-loaded particles prepared using this method suffer from low flavor encapsulation rates and easy aroma evaporation. During the storage and transportation of tobacco products, the carrier's weak binding force on the flavorings allows highly volatile aroma components to easily dissipate, resulting in poor aroma stability over the product's shelf life. Furthermore, some inorganic porous carriers may produce off-gases during combustion, affecting the purity of the smoke.

[0005] The second method is microencapsulation. This involves encapsulating the fragrance into microcapsule particles using a wall material. While microencapsulation technology improves aroma stability to some extent, existing microcapsule wall materials (such as some synthetic polymers) may produce irritating odors during pyrolysis, and the rupture temperature of the wall material is often difficult to precisely match with the temperature field during smoking. If the rupture temperature is too high, aroma release is delayed, and the smoker cannot perceive the characteristic aroma in the initial stages of inhalation; if the rupture temperature is too low, leakage is likely to occur during storage. Furthermore, the preparation process of microcapsules is usually quite complex, involving emulsification, polymerization, and other steps, resulting in higher production costs and greater difficulty in controlling residual solvents.

[0006] The third method is gel granulation. This involves mixing gelling agents such as sodium alginate and gelatin with flavorings and then dripping the mixture to solidify it into granules. While these granules have good formability, their mechanical strength is usually low, making them prone to breakage during the turning and conveying processes in tobacco processing, leading to premature release of flavorings or contamination of equipment. Furthermore, the moisture content of gel granules is difficult to control; excessive moisture can cause tobacco mold growth, while insufficient moisture makes the granules brittle.

[0007] Existing flavoring technologies for tobacco generally suffer from problems such as low aroma loading, poor storage stability, and insufficient sensory comfort when smoking. Therefore, it is of great significance to develop a flavoring granule for tobacco with high aroma loading, excellent stability, and improved smoking experience. Summary of the Invention

[0008] In order to overcome the problems existing in the background art, the present invention provides a tobacco fragrance-carrying granule, its preparation method and application.

[0009] To achieve the above objectives, the first aspect of the present invention provides a method for preparing flavor-carrying granules for tobacco, comprising the following steps:

[0010] S1. Wash, dry, and crush corn stalks, sugarcane bagasse, and peanut shells. Then, mix the corn stalk powder, sugarcane bagasse, and peanut shell powder in a mass ratio of 35-40:20-25:10-14. Add 8-10% of the total weight of corn flour (corn stalk powder, sugarcane bagasse, and peanut shell powder) and mix evenly to obtain the base material.

[0011] S2, add water to the base material and stir evenly until the moisture content is 60-70%, then pack and sterilize; add Ganoderma lucidum ( Ganoderma lucidum The inoculum was inoculated into the sterilized bagged substrate and cultured at a temperature of 25–30°C and a humidity of 70%–85% until the mycelium filled the bag.

[0012] S3, after removing the uncontaminated substrate covered with mycelium from the bag and dispersing it, dry it at 45-50℃ until the moisture content is less than 13% to obtain dried granules;

[0013] S4. Using a tunnel microwave device, the dried particles are subjected to mycelial inactivation treatment at a microwave power of 50-60kW, and the water content is reduced to below 8% to obtain carrier particles.

[0014] S5. Crush the carrier particles to 30-40 mesh to obtain tobacco fragrance carrier particles.

[0015] Furthermore, the mass ratio of corn stalk cob, sugarcane bagasse, and peanut shell powder is 38:23:12.

[0016] Furthermore, in step S1, the corn stalks, sugarcane bagasse, and peanut shells are washed, dried, and crushed to 20 mesh.

[0017] The second aspect of the present invention provides tobacco flavoring particles prepared by the method described in the first aspect.

[0018] A third aspect of the present invention provides a tobacco filter rod, comprising: an aroma-enhancing substance and tobacco flavor-carrying particles prepared by the method of the first aspect; the aroma-enhancing substance is loaded onto the tobacco flavor-carrying particles and filled into the tobacco filter rod.

[0019] A fourth aspect of the present invention provides a cigarette comprising the filter rod described in the third aspect.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention utilizes the growth of Ganoderma lucidum fungal mycelium inside the substrate. The mycelium naturally extends and intertwines to form a network structure, which not only increases the specific surface area of ​​the carrier, but also achieves dual fixation of flavoring substances through physical adsorption and biological matrix adsorption, significantly enhancing the binding force of the flavor.

[0022] 2. This invention utilizes the growth of Ganoderma lucidum mycelium inside the substrate particles to form a stable biological network; then, through microwave treatment, microorganisms are killed on the one hand, and residual moisture is vaporized by microwave heating and drying on the other hand, which further opens the channels and fixes the mycelial network.

[0023] 3. Traditional carriers rely on external adhesives (such as konjac powder and cactus leaf pulp powder) to enhance particle strength. In this invention, the network structure formed by mycelial growth itself plays a natural role in strengthening the skeleton and bonding, so no external adhesive is needed.

[0024] 4. The flavor-carrying particles for tobacco of the present invention have high flavor loading capacity and excellent flavor stability. Detailed Implementation
