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 cigarette liquid of an electronic cigarette, and particularly relates to a high-fragrance tobacco extract and application thereof. The extract is prepared through the steps of heating baking, low-temperature extraction, ultrafiltration membrane filtering, molecular distillation and the like. Through the increase of baking procedures, the aroma substance concentration is well increased; by using a low-temperature extraction technology, the original fragrance features of the tobacco are well maintained; meanwhile, thermosensitive substances are well protected; further, a membrane separation-molecular distillation process is used, so that the aroma substances are well enriched; meanwhile, macromolecular substances such as sugar, protein and resin and high-boiling-point substances of long-chain aliphatic hydrocarbon and the like in the tobacco extract can be well removed. After a proper number of high-fragrance tobacco extract provided by the invention is added into the cigarette liquid of the electronic cigarette, the cigarette fragrance of the electronic cigarette is intense; no burnt smell exists; in addition, the aftertaste harmony is good; the fragrance transmission performance is good; a well application effect is shown; good popularization and application prospects are realized.

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...
