Problems solved by technology

However, most e-cigarette liquids are directly added with tobacco extracts used in traditional cigarettes. These extracts often contain a large amount of reducing sugars such as glucose and fructose. These substances are difficult to vaporize under the heating conditions of e-cigarettes and are easy to deposit on Carbonization on the heating wire produces a burnt smell, which affects the heating and atomization effect of the electronic cigarette, and also affects the smoking taste of the electronic cigarette and the service life of the atomizer

preparation example Construction

[0023] The invention provides a kind of preparation method of tobacco absolute, comprising the following steps:

[0024] a) fermenting tobacco stems, water and Hansenula yeast mixed to obtain a fermented product;

[0025] b) adjusting the pH value of the fermented product to 10-13, and then extracting with a hydrophobic organic solvent to obtain an extract;

[0026] c) After removing the hydrophobic organic solvent in the extract, adding alcohols to redissolve and cool to obtain a cooled product;

[0027] d) Separating the cooled product into solid and liquid, and removing the alcohols in the separated liquid to obtain tobacco absolute.

[0028] According to the present invention, tobacco stems, water and Hansenula yeast are mixed and fermented to obtain fermented products.

[0029] In the present invention, the tobacco stem is the discarded shredded tobacco stem. The tobacco stems are preferably tobacco stem powders, that is, the waste tobacco stems are crushed into powder...

Embodiment 1

[0052] 1.1 Preparation of absolute oil

[0053] Weigh 1000g of crushed waste tobacco stems and put them into a reaction tank, add 3000g of water and 10g of Hansenula anomaly 31399 dry powder, heat to 28°C, stir at 20rpm, and anaerobically ferment for 72h to obtain a fermented product. After the pH of the obtained fermented product was adjusted to 12 with sodium hydroxide, 3000 mL of petroleum ether was added for extraction, and the extraction was performed three times, and the extracts were combined to obtain the total extract. After the obtained extract was heated under reduced pressure to remove petroleum ether, 95% ethanol was added to redissolve it, and then put into a refrigerator, refrigerated at -10°C for 12 hours, then taken out, filtered to remove the precipitate, and heated under reduced pressure to recover ethanol to obtain tobacco net Oil (denoted as S1).

[0071] 1.1 Preparation of absolute oil

[0072] Weigh 1000g of crushed discarded tobacco stems and put them into a reaction tank, add 2000g of water and 5g of Hansenula anomaly 31399 dry powder, heat to 28°C, stir at 50rpm, and anaerobically ferment for 96h to obtain a fermented product. After the pH of the obtained fermented product was adjusted to 13 with sodium hydroxide, 2000 mL of ethyl acetate was added for extraction, and the extraction was performed 5 times, and the extracts were combined to obtain the total extract. After removing the ethyl acetate by heating the obtained extract under reduced pressure, add 95% ethanol to redissolve it, then put it into the refrigerator, refrigerate at -10°C for 12 hours, take it out, filter to remove the precipitate, and recycle the ethanol by heating under reduced pressure to obtain tobacco Absolute oil (denoted as S2).

Abstract

The invention provides tobacco absolute, a preparation method thereof and E-liquid. The preparation method of the tobacco absolute comprises the steps that 1, tobacco stems, water and Hansenula polymorpha are mixed and fermented, and yeast is obtained; 2, the PH value of the yeast is adjusted to be 10-13, extraction is conducted with a hydrophobic organic solvent, and an extracting solution is obtained; 3, after the hydrophobic organic solvent in the extracting solution is removed, alcohols are added for redissolution and cooling, and refrigerant is obtained; 4, the refrigerant is subjected tosolid-liquid separation, the alcohols in obtained separation liquid are removed, and the tobacco absolute is obtained. Accordingly, waste tobacco stems serve as the raw materials, by means of the special preparation method, a large amount of reducing sugar is removed, carbonization and gelatinization problems in electronic cigarettes are solved, the obtained absolute generates fresh and mellow aroma components, the tobacco aroma is enriched, and the smoking quality is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a tobacco absolute, a preparation method thereof and electronic cigarette oil. Background technique [0002] In recent years, domestic and foreign tobacco companies have continuously promoted the development of new tobacco products. Among them, electronic cigarettes, as an important form of new tobacco products, have achieved explosive development. E-cigarettes are usually composed of two parts: e-cigarettes and e-liquid (or called e-liquid). Among them, the main component of e-cigarette is propylene glycol, glycerin or polyethylene glycol containing nicotine, and various flavors are prepared by adding various flavors. , to meet the needs of different smokers. However, the use of a large number of artificial flavors and fragrances makes electronic cigarettes very different from cigarette products in terms of aroma and taste, and the smoke taste is weak, lacks natural aroma and f...
