[0059] In some embodiments, the first mass ratio in step S100 is 1:(0.1%-0.5%). Specifically, the mass ratio of the tobacco raw material to the complex enzyme solution can be set to any one of 1:0.1%, 1:0.2%, 1:0.3%, 1:0.4%, 1:0.5% or a range between any two values.

[0060] In some embodiments, the tobacco raw material in step S100 is selected from one or more of Yunnan tobacco or Zimbabwe tobacco leaves. The selection of tobacco raw materials can optimize the aroma of refined tobacco, and can provide users with an ideal taste without adding nicotine salt to the atomized liquid, thereby improving the user's experience.

[0061] In some embodiments, the composite enzyme solution in step S100 includes amylase, saccharifying enzyme and protease mixed in a fifth mass ratio, wherein the fifth mass ratio is (1-2): (1-2): (1-3). Specifically, in the composite enzyme solution, the mass ratio of the amylase, saccharifying enzyme and protease can be set to any one of 1:1:1, 1:2:1, 1:2:3, 1:1:3, 2:1:1, 2:2:1, 2:2:3 or a range formed between any two values.

[0072] The first treatment of the present application removes the insoluble substances in the first mixed solution through filtration treatment. Since the average free path of light molecules in the tobacco raw materials is large and the average free path of heavy molecules is small, further molecular distillation treatment is used to make the light molecules fall on the condensation surface, and the heavy molecules return to the original liquid surface because they cannot reach the condensation surface, thereby realizing the separation of light components and heavy components in the tobacco raw materials, and then realizing the separation of the middle and front aroma and the middle and back aroma of the tobacco refined product, so as to facilitate the subsequent combination and adjustment of the overall aroma of the tobacco refined product and improve the user experience.

[0081] In the embodiment of the present application, the second mixed solution is centrifuged to fully separate the wax component in the heavy component, thereby eliminating the residual oily substance in the tobacco refined product and improving the quality of the tobacco refined product.

[0082] In some embodiments, the fourth mass ratio in step S600 is (0.5-5):1. Specifically, the mass ratio of the first extract to the third extract in the tobacco refined product can be set to any value of 0.5:1, 1:1, 2:1, 3:1, 4:1, 5:1 or a range between any two values.

[0128] Step (2), mixing 4% nicotine salt, 15% tobacco flavor, 40% vegetable glycerin and 35% propylene glycol to obtain an atomized liquid.

[0129] Comparative Example 6

[0130] The difference between this comparative example and Example 1 is that in step (1), Yuyan tobacco extract is used instead of Yunyan 97 tobacco extract.

[0131] In order to further illustrate the beneficial effects of the tobacco refined product provided by the embodiment of the present invention, the following is further described in detail in conjunction with specific test examples:

[0132] Experiment 1: Sensory evaluation effect

[0133] A panel of 20 professional electronic cigarette smokers evaluated the above Examples 1 to 3, Comparative Examples 1 to 6, and commercially available products as samples, and the overall test results are shown in the following table. For sensory evaluation of e-liquid, each index option is scored from 0 to 100 points. The higher the score, the stronger the reaction to the index option. The test results are shown in Table 1.

[0134]

[0135] Table 1

[0136] According to the records in Table 1, by comparing the experimental data of Examples 1 to 3 and Comparative Examples 1 to 6 with the commercially available products, it can be known that the atomized liquid prepared by using the tobacco refined product provided in the examples of the present application as the tobacco flavor is better than the sensory evaluation of Comparative Examples 1 to 6 and the commercially available products in all aspects of sensory evaluation. The atomized liquid prepared in the examples of the present application has good aroma, coordination and reducibility. The treatment of the composite enzyme has a positive effect on the flavor enhancement of the light-fragrant tobacco. The molecular distillation treatment is conducive to enhancing the aroma and reducing the impurities; the high-speed centrifugal treatment is conducive to enhancing the taste and aftertaste of the treated part.

[0137] Test 2: Carbon deposition evaluation

[0138] The atomizer core is filled with the corresponding atomizer liquid, and the corresponding number of puffs are inhaled through external equipment. Professional electronic atomizer equipment tasters evaluate the consistency of flavor before and after the corresponding number of puffs, and disassemble the atomizer core to observe the surface of the heating element to judge the carbon deposition (+ indicates carbon deposition and poor flavor consistency, - indicates no carbon deposition and good flavor consistency). The test results are shown in Table 2:

[0139]

[0140]

[0141] Table 2

[0142] According to the records in Table 2, by comparing the experimental data of Examples 1 to 3 and Comparative Examples 1 to 6 with the commercially available products, it can be learned that the treatment with the composite enzyme is beneficial to the enzymatic hydrolysis of macromolecules, alleviates carbon deposition, and reduces the attenuation of flavor. The treatment with molecular distillation and high-speed centrifugation is beneficial to further separate the macromolecules, reduce carbon deposition, and maintain the consistency of flavor. Compared with the embodiments of the present application, the commercially available products are more prone to carbon deposition and have poor flavor consistency.

[0143] To sum up, the embodiment of the present application adopts the tobacco flavor as described above, which can improve the overall aroma of the atomized liquid and further improve the user experience; at the same time, since the macromolecular substances of the tobacco refined products in the tobacco flavor are all hydrolyzed, the atomized liquid is prevented from causing the atomizer core to stick during the heating and atomization process, and there is no burnt smell that affects the overall taste of the atomized liquid, thereby improving the user experience and the service life of the electronic atomization device.
