Description

Technical Field

[0001] This invention belongs to the field of tobacco flavoring technology, and relates to a tobacco flavoring with passion fruit flavor and adsorbent particles and their application in cigarettes. Background Technology

[0002] Fruity flavorings are a common type of natural flavoring in cigarettes, providing aromas such as fruit, sweetness, and acidity, and enhancing the smoothness and roundness of the smoke. However, the effective flavor components in fruity flavorings are relatively more prone to volatilization and loss, resulting in poor stability and limited effectiveness in cigarette flavoring. Therefore, fruity flavorings 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, fruit flavorings are a multi-component mixture. Directly applying slow-release processing to flavorings during the extraction process will change the original proportions of the components, leading to an alteration in the original flavor. Therefore, it is necessary to adjust the components of slow-release flavorings to maintain their essential 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 adsorbent particles with passion fruit flavor and their application in cigarettes.

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

[0008] In a first aspect, the present invention provides a tobacco flavoring with passion fruit flavor, wherein the components of the tobacco flavoring include passion fruit peel essential oil, hexanoate, benzaldehyde, methyl farnesylbutyrate, geraniol, nerolidol and β-bisabolene.

[0009] This invention creatively combines passion fruit peel essential oil with six specific flavoring components: hexyl hexanoate, benzaldehyde, methyl farnesylbutyrate, geraniol, nerolidol, and β-bisabolene, to form a mixed flavoring. Compared to using passion fruit peel essential oil alone, the components in this flavoring work synergistically to provide a passion fruit-like flavor when smoking cigarettes, significantly enhancing the fruity aroma characteristics and aroma harmony of cigarettes, and improving the smoke characteristics of cigarettes. Furthermore, when this flavoring is used in a slow-release process, it maintains the stability of the passion fruit-like flavor, preventing changes in the original component ratios 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, by mass parts, include 100 parts passion fruit peel essential oil, 3-5 parts hexanoate, 0.5-1 part benzaldehyde, 0.5-1 part farnesylbutyrate, 1-2.5 parts geraniol, 2-2.5 parts nerolidol, and 1-2 parts β-bisabolene.

Other specific values ​​not listed above within the above range are also acceptable and will not be elaborated further here.

[0017] Preferably, the mass ratio of the extract to ethanol is 1:(8-12), such as 1:8, 1:9, 1:10, 1:11, 1:12, etc. Other specific values ​​not listed in this range can be selected, and will not be elaborated here.

[0020] Loading the tobacco blend flavoring involved in this invention into starch-based adsorbent particles can achieve the slow release of flavoring. When added to cigarettes, it can further enhance the aroma, richness, delicacy / smoothness / roundness and fruity characteristics of cigarettes during smoking, thereby improving the sensory performance of cigarettes.

[0023] Preferably, the diameter of the starch-based adsorbent particles is 0.5-1 mm, such as 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc. Other specific values ​​not listed in this range can be selected, and will not be elaborated here.

[0024] Preferably, the starch-based adsorbent particles are prepared by a method comprising the following steps:

[0025] Plant starch is dispersed in water to form a starch suspension. The starch suspension is then subjected to high-temperature gelatinization and cooled. The gelatinized liquid is dripped into vegetable oil to form spherical particles. The spherical particles are washed and dried to obtain the starch-based adsorbent particles.

[0026] Preferably, the concentration of the starch suspension is 8-12 wt%, such as 8 wt%, 9 wt%, 10 wt%, 11 wt%, 12 wt%, etc. Other specific values ​​not listed in this range can be selected, and will not be elaborated here.

[0027] Preferably, the high-temperature gelatinization treatment is carried out in a high-pressure reactor at a temperature of 115-125°C, such as 115°C, 120°C, 125°C, etc., and for a time of 15-25 min, such as 15 min, 18 min, 20 min, 22 min, 25 min, etc. Other specific values ​​not listed within this range can be selected, and will not be elaborated here.

[0028] Preferably, the washing is performed using ethanol.

[0033] This invention creatively combines passion fruit peel essential oil with six specific flavoring components: hexyl hexanoate, benzaldehyde, methyl farnesylbutyrate, geraniol, nerolidol, and β-bisabolene, to form a mixed flavoring. The components in this flavoring work synergistically to provide a passion fruit-like flavor when smoking cigarettes, significantly enhancing the fruity aroma characteristics and aroma harmony, and also improving the smoke characteristics of cigarettes.

[0104] Experimental Example
