Description

Technical Field

[0001] This invention belongs to the field of tobacco flavoring technology, and relates to a tobacco flavoring with a sweet fruity aroma and flavoring adsorption particles and their application in cigarettes. Background Technology

[0002] Bergamot essential oil is rich in limonene, linalool, and linalyl acetate, possessing a fresh, sweet citrus aroma. It can neutralize the harshness of tobacco, mask impurities, and enhance the elegance and complexity of the smoke. However, the effective flavor components in bergamot essential oil are easily volatilized and lost, resulting in poor stability and limited effectiveness when used in cigarette flavoring. Therefore, natural flavorings such as bergamot essential oil often require processing before use.

[0003] CN120130687A discloses a cigarette flavor capsule based on tangerine peel and its application. The cigarette flavor capsule adopts a three-layer microencapsulation structure, including an inner layer, a middle layer and an outer layer. The three-layer microencapsulation structure design allows the tangerine peel flavor, fruit aroma and floral aroma to continuously blend in the oral cavity and nasal cavity, greatly prolonging the flavor persistence. It can remain in the oral cavity for a period of time after smoking, bringing a long-lasting aftertaste.

[0004] CN109645555A discloses a method for preparing and applying fruit-flavored tobacco fibers for novel heated tobacco products. The method involves uniformly mixing flavored microcapsules, polylactic acid, blended materials, and a plasticizer, followed by melt spinning. The flavor is encapsulated within microcapsules using a complex coagulation method. These microcapsules are then melt-spun with a fiber-forming substrate. During the spinning process, the flavoring is not directly heated, which inhibits thermal decomposition and reduces flavor loss. As smoke passes through, the micropores in the microcapsule walls allow for the slow release of the flavor, resulting in a long-lasting aroma in the heated tobacco.

[0005] However, bergamot essential oil is a multi-component mixture. Directly slow-release processing of the fragrance will change the original proportions of the components during the extraction process, resulting in a change in the original flavor of the fragrance. Therefore, it is necessary to adjust the components of slow-release fragrances to maintain their necessary sensory characteristics. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a tobacco flavoring and flavoring adsorbent particles that present a sweet and fruity flavor, and their application in cigarettes.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides a tobacco flavoring that presents a sweet and fruity aroma, wherein the components of the tobacco flavoring include bergamot peel essential oil, ocimene, linalool, β-phellandrene, limonene, cyclohexene and β-caryophyllene.

[0009] This invention creatively combines bergamot peel essential oil with six specific flavoring components—ocimene, linalool, β-phellandrene, limonene, cyclohexene, and β-caryophyllene—to form a mixed flavoring. Compared to using bergamot peel essential oil alone, the components in this flavoring work synergistically to provide a sweet fruity flavor when smoking cigarettes, significantly enhancing the fruity, sweet, and fresh aroma characteristics of cigarettes with good aroma harmony and improving the smoke characteristics of cigarettes. Furthermore, when this flavoring is used in a slow-release process, it maintains the stability of the sweet fruity flavor and does not change due to changes in the original proportions of the components during the slow-release process, thus achieving stability in sensory performance and comprehensively improving the sensory quality of tobacco products.

[0010] Preferably, the components of the tobacco flavoring include, by mass parts, 100 parts of bergamot peel essential oil, 3-5 parts of ocimene, 6-7 parts of linalool, 2-4 parts of β-phellandrene, 1-2.5 parts of limonene, 1-2 parts of cyclohexene, and 1-2 parts of β-caryophyllene.

[0032] Fourthly, the present invention provides the use of the tobacco flavoring according to the first aspect or the tobacco flavoring adsorbent particles according to the second aspect in the preparation of cigarettes.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] This invention creatively combines bergamot peel essential oil with six specific flavoring components—ocimene, linalool, β-phellandrene, limonene, cyclohexene, and β-caryophyllene—to form a mixed flavoring. Compared to using bergamot peel essential oil alone, the components in this flavoring work synergistically to provide a sweet fruity flavor when smoking cigarettes, significantly enhancing the fruity, sweet, and fresh aroma characteristics of cigarettes with good aroma harmony and improving the smoke characteristics of cigarettes. Furthermore, when this flavoring is used in a slow-release process, it maintains the stability of the sweet fruity flavor and does not change due to changes in the original proportions of the components during the slow-release process, thus achieving stability in sensory performance and comprehensively improving the sensory quality of tobacco products.

[0105] Experimental Example

[0106] In this experiment, cigarettes prepared using Examples 1-5 and Comparative Examples 1-8 were used as sample cigarettes, while blank cigarettes were mixed with an equal amount of solvent to serve as reference cigarettes. All cigarettes were sealed and stored at (22±1)℃ and 60%±2% relative humidity for at least 48 hours. The smoke characteristics and aroma features of the sample and reference cigarettes were sensorily evaluated according to the methods in YC / T 497-2014, "Sensory Evaluation Method for Chinese-style Cigarettes".

[0109] Table 2

[0110]

[0111] As can be seen from the data in Tables 1 and 2, compared with blank cigarettes, adding the tobacco flavoring adsorbent particles involved in this invention to cigarettes not only provides a sweet fruity flavor when smoking the cigarettes, but also gives the cigarettes superior smoke characteristics and aroma features, resulting in a comprehensive improvement in sensory evaluation.

[0112] Comparing Application Example 1 with Comparative Application Example 8, it can be seen that loading the tobacco blend flavoring involved in this invention onto silica gel adsorbent particles and adding it to cigarettes can further improve the smoke characteristics and aroma features of cigarettes during smoking, thereby improving the sensory performance of cigarettes.

[0113] Comparing Application Example 1 with Comparative Application Example 7, it can be seen that, compared with using only bergamot peel essential oil as a flavoring agent, the tobacco flavoring agent involved in this invention, after being used in a slow-release process, can maintain the stability of the sweet fruity flavor and will not change the flavoring agent due to the change in the original proportion of the components during the slow-release process, thereby achieving the stability of sensory performance and comprehensively improving the sensory quality of tobacco products.

[0114] Comparing Application Example 1 with Comparative Application Examples 1-6, it can be seen that the components in the tobacco flavoring involved in this invention work together to enhance the smoke characteristics and aroma features of cigarettes, resulting in a synergistic effect and a comprehensive improvement in the sensory quality of tobacco products.
