Problems solved by technology

This traditional method, 1. The extraction efficiency is not high, because a certain solvent is easy to reach saturation, and the required aroma components can no longer be extracted from the tobacco; 2. In order to improve the extraction efficiency, it will be heated until reflux, and the temperature will rise to the solvent. The boiling point will also bring unnecessary miscellaneous gases to the extracted product; 3. It needs to be filtered after extraction, especially for the filtration after soot extraction, which is very time-consuming
[0004] At present, a common problem with e-cigarette products is that e-cigarette liquids lack or have weak tobacco flavor characteristics, and some are even closer to food such as chewing gum. There is a large deviation in style from smoking cigarettes, and the overall style is close to food

Embodiment 1

[0032] Soak 110g of Zimbabwean L10F shredded tobacco in 200mL of absolute ethanol for 4h, and extract it with the improved Soxhlet extraction device of the present invention for 3h, the vacuum degree is 40mmHg, the heating temperature of the water bath is 50°C, the extract is concentrated under reduced pressure until the solvent is dry, and the concentrate is obtained by (5mL water + 5mL absolute ethanol + 20mL glycerin) was dissolved, flavored as e-cigarette liquid, and prepared as a test sample. The e-cigarette produced in the comparative example was used as a control, and the sensory evaluation was carried out. The result of the evaluation and evaluation was: it has obvious characteristics of Zimbabwean smoke, and the smoke is fuller and more mellow. Compared with the control, the flue gas of the test sample is purer. The GC-MS picture of the flue-cured tobacco extract obtained figure 2 As shown, because the peak of nicotine is too large, in order to clearly show other co...

Embodiment 2

[0034] Soak 10g of Zimbabwe L10F with 200mL of n-hexane for 4h, extract with the improved Soxhlet extraction device of the present invention for 3h, the vacuum degree is 80mmHg, the water bath heating temperature is 45°C, the extract is concentrated under reduced pressure until the solvent is dry, and the concentrate is extracted with (5mL Water + 5mL absolute ethanol + 20mL glycerin) dissolved, flavored as e-cigarette liquid, and tested. Taking the e-liquid prepared in Example 1 as a control, the sensory evaluation and smoking evaluation results are as follows: Compared with the control, the test sample has more energy, a stronger sense of satisfaction, and a little miscellaneous gas.

[0035] image 3 It is the GC-MS figure and figure 2 superposition. From image 3 It can be seen that ethanol is a polar solvent, while n-hexane is used as a non-polar solvent, and the aroma components extracted by the non-polar solvent n-hexane are densely distributed in the area with a sh...

Embodiment 3

[0037] Soak Sangzhi B3F Zimbabwe L10F in 200mL of n-hexane for 4h, extract for 3h with the improved Soxhlet extraction device of the present invention, vacuum degree is 80mmHg, water bath heating temperature is 45°C, the extract is concentrated under reduced pressure until the solvent is dry, and the concentrate is (5mL water + 5mL absolute ethanol + 20mL glycerin) is dissolved and used as the e-cigarette liquid for flavoring. Make two samples, one with 0.5ml of commercially available e-cigarette liquid as a control sample; the other as an experimental sample, add 0.5ml of the same commercially available e-cigarette liquid as the control sample, and add another 0.25ml prepared in this example The smoke liquid was extracted from the flue-cured tobacco, and the results of the comparative evaluation and smoking evaluation are as follows: Compared with the control sample, the experimental sample has obvious characteristics of tobacco aroma, strong vigor and strong sense of satisfac...

Abstract

The invention discloses flue-cured tobacco extract and electronic cigarette liquid. Tobacco leaves, tobacco shreds, tobacco powder and / or tobacco ash of flue-cured tobacco serve as raw materials for the flue-cured tobacco extract, and extract solvent is added into a Soxhlet extractor so that Soxhlet extraction can be conducted on the raw materials; as an improvement, a vacuum pump is connected to a condensation pipe of the Soxhlet extractor so that the vacuum degree in the Soxhlet extractor can be kept within the range of 20 mmHg to 80 mmHg; the temperature of condensate in the condensation pipe is 5 DEG C below zero or lower; after Soxhlet extraction is completed, the condensate is collected and concentrated into the flue-cured tobacco extract. A whole Soxhlet extraction system is in a negative pressure state, the boiling point of the extract solvent is reduced, the extraction temperature is reduced, the solvent circulation in the extraction process is accelerated, the extraction frequency is increased, and efficiency is higher. Meanwhile, the solvent heating temperature is lower, and therefore the extraction condition is more moderate, the excessive chemical reaction, caused by solvent high-temperature heating, between aroma components in the extract is avoided, and the extract contains less offensive odor.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, in particular to a flue-cured tobacco extract and electronic cigarette liquid. Background technique [0002] As a new type of tobacco product, electronic cigarette liquid determines the sensory style characteristics of electronic cigarette, so the preparation of electronic cigarette liquid becomes the key to electronic cigarette products. The basic technical principle of the electronic cigarette is that when smoking the electronic cigarette, the battery of the electronic cigarette supplies power to the atomizer of the electronic cigarette, the atomizer starts to work, and atomizes the liquid stored in the electronic cigarette to generate smoke. The smoke liquid in electronic cigarettes, also known as "smoke oil", is stored in absorbent materials, commonly known as "adsorbent cotton". The liquid in the e-cigarette is actually a formula essence, which is atomized into "smoke" when sm...
