Description

Technical Field

[0001] The present application relates to the technical field of electronic cigarettes, and in particular to passion fruit flavor essence and electronic cigarette oil and applications thereof. Background Art

[0002] In recent years, with the development of the global tobacco control movement and consumers' increasing health awareness, new tobacco products such as e-cigarettes have emerged. The smoke produced by e-cigarette oil can simulate the throat hit of real tobacco gas, and does not contain harmful substances such as tar and carbon monoxide. Therefore, e-cigarettes have become popular all over the world. In addition, the taste of e-cigarette oil is another major selling point. At present, there are many flavors of e-cigarette oils on the market, but most of them are mainly tobacco flavor and mint, which is still relatively monotonous and difficult to meet the needs of more users for the taste and taste of e-cigarettes.

[0003] The current passion fruit flavor is usually added with passion fruit extract, and the aroma substances in it are easy to escape or degrade during the processing, which leads to a huge change in the aroma components, seriously affecting the quality and flavor of the passion fruit flavor. In addition, the aroma of ordinary flavors is monotonous and cannot be coordinated with tobacco smoke, and cannot be directly applied to electronic cigarette oil. Therefore, it is necessary to provide a passion fruit flavor that can be used in the field of electronic cigarettes and an electronic cigarette oil containing the same. Summary of the invention

[0004] In view of this, the present application provides a passion fruit flavor essence and an electronic cigarette oil comprising the same. The passion fruit flavor essence can be used to prepare electronic cigarette oil to produce smoke with a coordinated tobacco and passion fruit composite aroma.

[0077] Comparative Example 4

[0078] The only difference from Example 1 is that (2) Preparation of passion fruit flavor: The following components in parts by weight are added to 5 parts by weight of propylene glycol: 0.12 parts of methoxyacetone, 0.18 parts of ethyl butyrate, 0.02 parts of cyclohexane, 0.14 parts of isoamyl acetate, 0.02 parts of 2-methylbutyric acid, 0.02 parts of leaf alcohol, 0.02 parts of butenone, 0.12 parts of ethyl n-hexanoate, 0.04 parts of D-limonene, 0.12 parts of isoamyl butyrate, 0.02 parts of dicyclopropane, 0.12 parts of allyl hexanoate, 0.02 parts of linalool, 0.06 parts of styroyl acetate, 0.02 parts of γ-decanoyl lactone and 0.02 parts of peach aldehyde.

[0079] Comparative Example 5

[0080] The only difference from Example 1 is that (2) Preparation of passion fruit flavor: The following components in parts by weight are added to 8 parts by weight of propylene glycol: 0.12 parts of methoxyacetone, 0.05 parts of cyclohexane, 0.05 parts of 2-methylbutyric acid, 0.05 parts of leaf alcohol, 0.05 parts of butenone, 0.1 parts of D-limonene, 0.05 parts of dicyclopropane, 0.05 parts of linalool and 0.05 parts of peach aldehyde.

[0081] The electronic cigarette liquids in the above embodiments and comparative examples were added to the electronic cigarette device, and 10 tobacco tasters conducted sensory evaluation on the prepared liquids from multiple aspects including flavor restoration (taste), flavor richness, flavor refinement, flavor naturalness, flavor coordination, aftertaste perception, coolness, throat hit, flavor persistence (smell), smoke volume, dryness, and experience stability in the scoring dimensions and scoring criteria in Table 1. The full score was 5 points (please see Table 1 for the scoring criteria), and the average score given by the 10 tobacco tasters was taken into the result. The results are shown in Table 2 for details.

[0082] Table 1 Sensory quality evaluation of electronic cigarette liquids corresponding to the aroma standards of each scale value of each item

[0083]

[0084] Table 2 Scoring table of electronic cigarette oils in various embodiments and comparative examples

[0085]

[0086] The scores of Examples 1-6 show that the passion fruit flavored electronic cigarette oil produces satisfactory results in terms of flavor reduction (taste), flavor richness, flavor delicacy, flavor naturalness, flavor coordination, aftertaste, coolness, throat hit, aroma persistence (smell), smoke volume, dryness, experience stability, etc. After adding an appropriate amount of tobacco extract, cooling agent, sweetener, taste improver and other substances to the oil, the performance of the oil can be further improved. Among them, the passion fruit flavored electronic cigarette oil of Examples 3-6 contains appropriate tobacco flavor and nicotine, which can bring a better throat hit and is more suitable for users with high smoking needs.

[0087] Compared with Example 6, the electronic cigarette oils of Comparative Examples 1-3 lack tobacco flavor and / or passion fruit flavor, and the results show that the fragrance coordination, aftertaste perception, etc. are not as good as the passion fruit flavor electronic cigarette oil of the present application. It can be seen from the comparative data that when tobacco flavor is missing, the throat hit score of the electronic cigarette oil is low, and when passion fruit flavor is missing, the electronic cigarette oil has a strong fragrance and a single taste, which will lead to problems such as too low aroma score and poor aftertaste perception. It can be seen that the electronic cigarette oil lacks tobacco flavor and / or passion fruit flavor and cannot provide users with a good sensory experience.

[0088] Comparative Example 4: C 2-9The content of low-level esters is not within the range described in the application. Compared with Examples 1-6, Comparative Example 4 performs poorly in terms of aroma intensity and experience stability. This may be because the excessive content of low-level esters causes the overall aroma to be too strong and pungent, covering up the passion fruit aroma, thereby affecting the aroma reduction, naturalness and delicacy, and the sustainability is poor. The passion fruit flavor prepared in Comparative Example 5 lacks the lipid substances described in the application, resulting in a low overall score for the e-cigarette oil, especially in terms of throat hit and experience stability.

[0089] The above is an exemplary embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made thereto without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
