Embodiment 1

[0043] The high-aroma tobacco extract provided by this application is prepared through the following steps:

[0044] (1) Take 1 kg of flue-cured tobacco raw material, put it in a tobacco processing machine, spray propylene glycol evenly according to the proportion of 10% of the mass of tobacco raw material, seal it and place it for 12 h to make it fully absorbed; then heat it to 80 °C and bake it for 1.5 h ;

[0045] (2) Grinding the material after the baking in step (1), adding the extract to carry out low-temperature extraction; after the extraction, separate the mixture to obtain the extract;

[0046] When separating and obtaining the extract, specifically use a 400-mesh filter cloth to filter out the extract;

[0047]95% ethanol is used for the extract; the mass ratio of solid to liquid during extraction is 1:10 (that is, in terms of mass ratio, tobacco raw material:extract = 1:10);

[0048] For the low-temperature extraction, the extraction temperature is -20°C, and the...

Embodiment 2

[0055] The preparation method of the high-aroma tobacco extract provided in this example is the same as in Example 1, and only some parameters are adjusted as follows:

[0056] In step (1), the amount of propylene glycol sprayed is 5% of the tobacco mass, and after being sealed and placed for 6 hours, it is heated to 120°C and baked for 0.5 hours;

[0057] In step (2), the ratio of solid to liquid is 1:10, the extraction temperature is 40 °C, the extraction time is 3 h, and the extraction is performed twice;

[0058] In step (3), the ultrafiltration membrane filtration parameter is: 10 kD;

[0059] In step (4), during molecular distillation, the pressure was set at 0.01 mbar, and the distillation temperature was 20 °C.

[0060] The e-cigarette liquid prepared by using the high-aroma tobacco extract in this example uses propylene glycol as a solvent, dilutes the high-aroma tobacco extract to a mass concentration of 5%, and can be used directly.

Embodiment 3

[0062] The preparation method of the high-aroma tobacco extract provided in this example is the same as in Example 1, and only some parameters are adjusted as follows:

[0063] In step (1), the amount of propylene glycol sprayed is 20% of the tobacco mass, and after being sealed for 8 hours, it is heated to 140°C and baked for 1 hour;

[0064] In step (2), the ratio of solid to liquid is 1:8, the extraction temperature is 20 °C, the extraction time is 6 h, and the extraction is performed twice;

[0065] In step (3), the ultrafiltration membrane filtration parameter is: 8 kD;

[0066] In step (4), during molecular distillation, the pressure is set to 0.05mbar, and the distillation temperature is 30°C.

[0067] The e-cigarette liquid prepared by using the high-aroma tobacco extract in this example uses propylene glycol as a solvent, dilutes the high-aroma tobacco extract to a mass concentration of 3%, and can be used directly.

Abstract

The invention belongs to the technical field of electronic cigarette liquid, and in particular relates to a high-aroma tobacco extract and its application. The extract is prepared through the steps of heating and baking, low temperature extraction, ultrafiltration membrane filtration, molecular distillation and the like. In this application, through the increase of the baking procedure, the concentration of aroma substances is better increased; and the adoption of low-temperature extraction technology better maintains the original aroma characteristics of tobacco, and at the same time better protects heat-sensitive substances; further, membrane separation ‑The adoption of the molecular distillation process enables better enrichment of the aromatizers, and better removal of sugars, proteins, resins and other macromolecular substances and long-chain aliphatic hydrocarbons and other high-boiling substances in the tobacco extract. Adding an appropriate amount of the high-aroma tobacco extract provided by this application to the e-cigarette liquid can make the e-cigarette have a strong smoke aroma, no burnt smell, and a good aftertaste and tonality. A good application effect has a good promotion and application prospect.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarette liquid, and in particular relates to a high-aroma tobacco extract and its application. Background technique [0002] E-cigarettes are electronic devices that deliver nicotine to the respiratory system through heating. When smoking, they can produce a feeling of "smoking" similar to traditional smoking. Compared with traditional cigarettes, because electronic cigarettes do not undergo combustion, do not contain harmful components such as tar, CO, and hydrocyanic acid, and do not produce second-hand smoke, soot and cigarette butts, they have become a substitute for traditional cigarettes in recent years in Europe and the United States. and other countries develop rapidly. [0003] In the prior art, the e-cigarette liquid used when smoking e-cigarettes mainly uses propylene glycol and glycerin as solvents. In order to improve the taste, it is supplemented with various flavors, such as c...
