Description

Technical Field

[0001] This invention relates to the field of heated cigarette technology, and in particular to a flavored cigarette core material, its preparation method, and its application. Background Technology

[0002] Cigarette blends consist of several to dozens of tobacco leaves. Because the chemical composition of these blends cannot be perfectly balanced, they will exhibit different aspects and degrees of defects when smoked, necessitating flavoring. Even a perfect blend will lack distinctive flavor without flavoring, failing to satisfy the needs of diverse tastes and preferences.

[0003] Currently, the common method of flavoring heated cigarettes is to directly spray flavoring agents into the cigarette core material. The drawbacks of this method are: if too little flavoring agent is applied, the characteristic aroma will be indistinct and fade quickly during smoking, affecting sensory quality; if too much flavoring agent is applied, it will cause the flavoring agent to penetrate the cigarette paper, forming yellow spots and affecting appearance quality.

[0004] CN106010794A discloses a method for preparing a fragrance essence for enhancing the aroma of agarwood in cigarettes and its application. The fragrance essence is prepared by mixing 15-25 parts of jujube oil, 0.1-1 parts of East Indian sandalwood oil, 0.2-2 parts of perilla frutescens, 3-10 parts of ethyl acetate, 0.5-5 parts of fragrant perilla oil, and 25-85 parts of ethanol, stirring, allowing to stand, and then filtering to remove sediment. The fragrance essence is then diluted with a 50-95% (w / w) ethanol solution and sprayed directly onto tobacco shreds to produce cigarettes.

[0005] CN116172241A discloses a method for preparing fragrance-loaded plant particles, comprising: (1) preparing a fragrance solution; (2) uniformly spraying the fragrance solution onto the surface of the core material particles, sealing and balancing, so that the fragrance is adsorbed onto the particles; (3) drying at room temperature, balancing the moisture content, adding talc or magnesium stearate, and sieving to obtain fragrance-loaded plant particles.

[0006] Existing technologies for adding flavorings by spraying cannot simultaneously satisfy both sensory and appearance quality requirements. Therefore, providing a method for preparing flavored cigarette core materials that improves the sensory quality of cigarettes, enhances the persistence, intensity, and consistency of flavor release, and simultaneously meets the appearance quality requirements of cigarettes is a problem that urgently needs to be solved. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a flavored cigarette core material, its preparation method, and its application. The preparation method of this invention combines adsorption flavoring and spray flavoring, reducing the amount of liquid flavoring applied and solving the appearance quality problem of yellow spots caused by excessive application of flavoring penetrating the cigarette paper. Simultaneously, adsorption flavoring compensates for the reduced amount of liquid flavoring and adsorbs the small molecules that contribute most to the aroma, thus jointly improving the appearance and sensory quality of heated cigarettes. To achieve this objective, this invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides a method for preparing flavored cigarette core material, the method comprising the following steps:

[0009] (1) Provide heated cigarette core material;

[0010] (2) The heated cigarette core material obtained in step (1) is adsorbed and flavored to obtain an adsorbed and flavored core material;

[0011] (3) Spray the adsorbent fragrance core material obtained in step (2) to add fragrance, and obtain the sprayed fragrance core material;

[0012] (4) Cut the sprayed flavored core material obtained in step (3) into shreds to obtain the flavored cigarette core material.

[0013] The conventional method of adding flavoring involves spraying the flavoring directly onto the heated cigarette core material. If too little is applied, the characteristic aroma will be indistinct and decay rapidly during smoking, affecting the sensory quality. If too much is applied, the flavoring will penetrate the cigarette paper, forming yellow spots and affecting the appearance quality.

[0014] This invention combines adsorption and spraying flavoring methods. On the one hand, it reduces the amount of liquid flavoring and fragrance applied, solving the appearance quality problem of yellow spots caused by excessive application of flavoring and fragrance penetrating the cigarette paper. On the other hand, it compensates for the reduced amount of liquid flavoring and fragrance applied by adsorption flavoring, and based on the principle of molecular diffusion, it adsorbs the small molecules that contribute the most to the aroma components, giving the heated cigarette its characteristic aroma, thus improving the appearance and sensory quality of the heated cigarette.

[0108] Test Example 1

[0109] Sensory effect evaluation

[0110] Test samples: heated cigarettes provided in Application Examples 1-10 and Comparative Application Examples 1-3.

[0111] Test method: Sensory evaluation of the samples was conducted using a scoring method. The evaluation panel consisted of 10 members, who scored the samples from five aspects: aroma characteristics, smoke characteristics, harmony, taste characteristics, and smoke generation characteristics. The scoring criteria are shown in Table 1.

[0112] Table 1

[0113]

[0114] Sensory evaluations of the heated cigarettes provided in each application example were conducted using the methods described above, and the results are shown in Table 2.

[0115] Table 2

[0116]

[0117] The test results show that:

[0118] (1) As can be seen from Application Examples 1 to 10, the present invention prepares flavored cigarette core material by combining adsorption flavoring and spray flavoring. The resulting heated cigarette has a strong aroma and high smoke characteristics, with better coordination, taste characteristics and smoke generation characteristics, and high overall sensory quality.

[0119] (2) By comparing Application Example 1 with Application Examples 4-8, it can be seen that if any one of pectinase, cellulase and hemicellulase is missing in the biological enzyme, or if the mass ratio of the three is not within the range specified in this invention, the enzymatic hydrolysis effect will be worse, and the overall sensory performance of heated cigarettes will be affected.

[0120] A comparison of Application Example 1 and Application Examples 9-10 shows that the movement of small molecule aroma substances is more easily stimulated at the temperature specified in this invention, thereby increasing the adsorption level of small molecule aroma substances and making the aroma of heated cigarettes more comfortable and natural, thus improving the overall sensory performance of heated cigarettes. If the temperature is too high, the core material will gradually lose water, causing the aroma of the tobacco in the core material to dissipate, which will affect the aroma characteristics of heated cigarettes.

[0121] (3) By comparing Application Example 1 with Comparative Application Example 1-2, it can be seen that using a single spraying method requires a larger amount of flavoring solution to be applied. This not only causes the flavoring to penetrate the cigarette paper and form yellow spots, but also reduces the overall sensory performance of the heated cigarette. Using a single adsorption method, even if the amount of flavoring is controlled to be the same, it is difficult to achieve a certain level of flavoring adsorption, resulting in the characteristic aroma of the heated cigarette not being prominent and the decay being strong, which affects the overall sensory performance of the heated cigarette.

[0122] The comparison between Application Example 1 and Comparative Application Example 3 shows that the material quality of the core material decreases after the fragrance is sprayed first. This not only reduces the processability but also affects the adsorption efficiency of subsequent fragrance adsorption, reduces the adsorption level of small molecule flavor substances, and affects the overall sensory performance of heated cigarettes.

[0123] The applicant declares that the above description is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention fall within the protection and disclosure scope of the present invention.
