It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] The method for preparing the moisturizing, sweetening and color-changing particles for filter rods provided by the present invention comprises the following steps:

[0034] Step (1): Using a granulation process, functional powder and adhesive are coated on the outside of core particles to obtain basic particles. The core particles are sugar particles or kudzu root particles, the functional powder is one of starch, wheat flour or herbal plant powder, and the adhesive is a sugar solution.

[0035] The granulation process may be, for example, spheronization, shearing, extrusion and fluidized bed granulation.

[0036] The particle size of the base particles can range from 15 to 24 mesh.

[0037] The particle size of the core particles in step (1) can be 30-50 mesh.

[0038] Furthermore, the core particles are granulated sugar with a particle size of 45-50 mesh.

[0039] The mass ratio of the functional powder to the core particles in step (1) may be (1-2):1.

[0040] Furthermore, the functional powder in step (1) is corn starch, and the mass ratio of the functional powder to the core particles is 1.5:1.

[0041] The mass ratio of the solute to the solvent in the adhesive in step (1) is (5-6):(4-5), and the mass ratio of the core particles to the adhesive is (2-3):1.

[0042] Furthermore, the adhesive in step (1) may be a syrup made from white sugar, lactose, and galactose.

[0043] In a specific implementation, the adhesive can be a syrup made from white sugar, and the mass ratio of white sugar to water is 1:1.

[0044] Step (2): Coating the base particles with a thermosensitive coating liquid using a coating process to obtain thermosensitive coated particles. The thermosensitive coating liquid is obtained by dispersing a thermosensitive color-changing material into a dispersion solution, wherein the dispersion solution is one of H-HPC, HPMC, and EC solutions, and the color change temperature of the thermosensitive color-changing material is 30°C-50°C.

[0045] The coating process may be, for example, spray coating, dip coating, or dry press coating.

[0046] The solvent used in the dispersion solution can be water, alcohol, or a mixture of water and alcohol. The amount of solute added to the dispersion solution can be 5wt%-8wt%. The weight gain of the solute in the dispersion solution on the surface of the moisturizing, sweetening, and color-changing granules can be 3wt%-7wt%.

[0047] For example, the solvent used in the dispersion solution is a mixture of water and alcohol, the mass ratio of water to alcohol is 8:2, the solute is HPMC, the solute addition amount of the dispersion solution is 7wt%, and the coating weight gain of the solute of the dispersion solution on the surface of the moisturizing and sweetening color-changing particles is 5wt%.

[0048] The amount of the thermosensitive color-changing material added to the thermosensitive coating solution can be 3wt%-5wt%, and the coating weight gain of the thermosensitive color-changing material on the surface of the moisturizing and sweetening color-changing particles is 4wt%-6wt%.

[0049] The thermochromic material can be a thermochromic material or a thermochromic material. The color of the thermochromic material can change from green to white, red to white, blue to white, or white to green.

[0050] For example, the thermochromic material is a thermochromic powder that changes color from green to white at 35°C. The amount of thermochromic material added to the thermosensitive coating solution is 4wt%. The coating weight gain of the thermochromic material on the surface of the moisturizing and sweetening color-changing granules is 5wt%.

[0051] During specific implementation, a spray coating process is adopted, and a peristaltic pump is used to pump the coating liquid, with a pumping flow rate of 8-12 mL / min, specifically 10 mL / min; the atomization air pressure is set to 0.2-0.24 mPa, specifically 0.22 mPa.

[0052] Step (3): Dry the thermosensitive coated granules at 40°C-60°C for 6-8 hours to obtain moisturizing, sweetening and color-changing granules.

[0053] In specific implementation, the drying temperature can be 50° C. and the drying time can be 6 hours.

[0054] The moisturizing, sweetening and color-changing particles of the present invention can be used for the visible section of the ternary cavity window filter rod, can improve the taste during smoking, and have a certain color-changing effect, thereby increasing the sensory comfort and novelty when smoking the cigarette.

[0055] Unless otherwise specified, the experimental methods used in the following examples are all conventional methods. The materials and reagents used are all commercially available unless otherwise specified. The equipment used in the experiments are all well known to those skilled in the art unless otherwise specified.

[0056] Example 1

[0057] Weigh the materials to a 1:1 weight ratio of granulated sugar to water, heat and dissolve, and continue boiling for 5 minutes after the sugar is completely dissolved, then cool to obtain the adhesive. Weigh the materials to a 1:1.5 weight ratio of granulated sugar to corn starch and a 2:1 weight ratio of granulated sugar to adhesive. First, place the granulated sugar into a centrifugal dusting granulator, where it tumbles on the machine's turntable. Pour the corn starch into the dusting device of the granulator, and pour the adhesive into the spray device of the granulator. The adhesive and corn starch are sprayed simultaneously to obtain the base granules. Prepare the solvent to a 8:2 weight ratio of water to alcohol. Weigh HPMC to a 93:7 weight ratio of solvent to solute (HPMC should be added to the solvent in small, multiple additions to avoid agglomeration of the HPMC powder, making it difficult to dissolve). Stir at 200 rpm for 6 hours at room temperature until completely dissolved, obtaining a dispersion solution. Disperse the thermochromic material in the dispersion solution at a 4 wt% concentration to obtain a thermosensitive coating solution. The base granules were coated with HPMC at a coating weight gain of 5wt% and the thermochromic material at a coating weight gain of 5wt%. The coating pan speed was 25 rpm, the blast temperature was 40°C, and the coating solution was supplied by a peristaltic pump at a pumping rate of 10 mL / min and an atomizing pressure of 0.22 mPa. After coating, the granules were dried at 40°C for 5 minutes to prevent excessive surface moisture content and resulting in sticking. The granules were then dried at 50°C for 6 hours to obtain the moisturizing, sweetening, and color-changing granules.

[0058] Example 2

[0059] The difference from Example 1 is that the mass ratio of granulated sugar to adhesive is 3:1.

[0060] Comparative Example 1

[0061] The difference from Example 1 is that the mass ratio of granulated sugar to adhesive is 1:1.

[0062] Comparative Example 2

[0063] The difference from Example 1 is that the mass ratio of granulated sugar to adhesive is 4:1.

[0064] The moisturizing, sweetening and color-changing particles obtained in Example 1-2 and Comparative Example 1-2 were loaded into the visible section of a ternary cavity window filter rod and evaluated by suction. The results are shown in Table 1.

[0065] Table 1

[0066]

[0067] As shown in Table 1, the oral sweetening effect of the moist-maintaining, sweet-returning, and color-changing granules is related to the ratio of binder to core granules. If the binder ratio is too high, the sweetening effect of the moist-maintaining, sweet-returning, and color-changing granules is not obvious, while if the binder ratio is too low, the granules cannot be prepared properly. The moist-maintaining, sweet-returning, and color-changing granules exhibit a sensitive temperature response. During the middle draw of the cigarette, the granules near the tobacco end begin to turn from green to white. With continued puffs, the color of the granules almost completely changes from green to white due to the relatively high smoke temperature in the last few puffs.

[0068] The moisturizing and sweetening color-changing granules obtained in Example 1 were subjected to temperature testing. Figure 1 As can be seen, when the particles are placed in 50°C hot water, they begin to change color within 3-4 seconds of contact, and the color of the particles changes from green to white within 16 seconds, demonstrating good temperature responsiveness. The image of the particles cooling down shows that when the particles are removed from the 50°C hot water, it takes about 40 seconds for the particles to turn from white to completely green. The color of the particles before heating and after cooling is basically the same, indicating that the color change of the particles is reversible and stable without attenuation.

[0069] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
