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 prod...

Embodiment 1

[0034] Take 10g of Burley tobacco S-B3F shredded tobacco and use 200mL of absolute ethanol as the extraction solvent to extract for 3 hours with the improved Soxhlet extraction device of the present invention, the vacuum degree is 40mmHg, the heating temperature of the water bath is 50°C, and the extract is concentrated under reduced pressure When the solvent is completely dry, the concentrate is dissolved with 5mL water + 5mL absolute ethanol + 20mL glycerin to obtain e-cigarette liquid. The e-cigarette produced in the comparative example was used as the control sample, and the sensory evaluation was carried out. The result of the smoking evaluation was as follows: the test sample had obvious characteristics of Burley tobacco aroma and was strong. Compared with the comparative example, the smoke fragrance is more pure. The GC-MS picture of gained Burley tobacco extract figure 2 As shown, because the peak of nicotine is too large, in order to clearly show other components, t...

Embodiment 2

[0036] Soak 10g of American Burley tobacco S-B3F tobacco powder in 200mL of n-hexane for 4h, extract for 3h with the improved Soxhlet extraction device of the present invention, the vacuum degree is 80mmHg, the heating temperature of the water bath is 45°C, and the extract is concentrated under reduced pressure to The solvent was completely dried, and the concentrate was dissolved in 5mL water + 5mL absolute ethanol + 20mL glycerin to obtain e-cigarette liquid. Taking the e-cigarette liquid produced in Example 1 as a comparison, the sensory evaluation results are as follows: greater energy, stronger sense of satisfaction, and a little miscellaneous smell.

[0037] image 3 The GC-MS figure and figure 1 contrast. 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 short retention time, that is, the left end o...

Embodiment 3

[0039] Soak 10g of American Burley tobacco S-C3F powdered tobacco in 200mL of ethanol for 4h, extract 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, and the extract is concentrated under reduced pressure until the solvent is completely dissolved. After drying, the concentrate was dissolved with 5mL water + 5mL absolute ethanol + 20mL glycerin to obtain electronic cigarette liquid. Make two samples, add 0.5ml of commercially available e-liquid to one as a control sample; add 0.5ml of the same commercially available e-liquid as the control sample to the other as an experimental sample, and add 0.25ml of the preparation prepared in this example Burley tobacco extract smoke liquid, comparative evaluation and evaluation results: Compared with the control sample, the Burley smoke smoke characteristics of the experimental sample are obvious, strong and satisfying.

Abstract

The invention relates to burley tobacco extractive, electronic tobacco juice and a tobacco extraction method. The raw materials of the burley tobacco extractive are tobacco leaves, cut tobacco leaves, tobacco powder and/or tobacco ash of burley tobacco, and Soxhlet extraction is carried out on the raw materials by adding an extraction solvent in a Soxhlet extraction device. The tobacco extraction method is characterized in that a condensation pipe of the Soxhlet extraction device is connected with a vacuum pump, and the vacuum degree of the Soxhlet extraction device keeps at 20-80 mmHg; the temperature of condensate in the condensation pipe is below minus 5 DEG C; after Soxhlet extraction, an extraction solution is collected and concentrated to obtain the burley tobacco extractive. The whole Soxhlet extraction system is in a negative pressure state, the boiling point of the extraction solvent is lowered, the extraction temperature is lowered, circulation of the solvent is accelerated in the extraction process, the extraction frequency is improved, and efficiency is higher. As the heating temperature of the solvent is lower, the extraction conditions are milder, extreme chemical reaction among aroma components in the extractive caused by high-temperature heating of the solvent is avoided, and less impurity gas in the extractive is generated.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a Burley tobacco extract, an electronic cigarette liquid and a method for extracting tobacco. 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 ess...
