preparation example Construction

[0070] The present invention provides a method for preparing a tobacco component (i.e. tobacco flavoring substance) applied to an electronic cigarette liquid, comprising the following steps:

[0071] (1) Step-by-step extraction of tobacco raw materials:

[0072] The first extraction: the raw material of mixed extractant 1 is prepared by mixing high-concentration ethanol (ethanol: water mass ratio = 90:10-99:1) and propylene glycol at a mass ratio of 95:5-100:0. Put the tobacco raw material into the extraction tank with a reflux device, add the mixed extractant 1 for heating and stirring extraction, the extraction temperature is 60-80°C, the mass ratio of the tobacco raw material to the extractant 1 is 1:5-1:7, and the extraction time is 0.5 ~1.5 hours. After extraction, the extract is separated from the raw material by methods including natural sedimentation, suction filtration, centrifugation and the like; the obtained first extraction liquid is used for future use, and the ...

Embodiment I-II、 comparative example I

[0090] Comparative example I

[0091] For the first extraction, 9.8kg of 95% ethanol (mass percentage of ethanol and water) was mixed with 0.2kg of propylene glycol to prepare mixed extractant 1. Weigh 1 kg of pulverized mixed tobacco flakes, add 5 kg of mixed extractant 1, heat and stir in a constant temperature oil bath, and extract for 1 hour at a temperature of 65°C, then seal the bottle mouth with a 300-mesh filter cloth, pour it out and collect Extract 1.

[0092] For the second extraction, 5kg of distilled water, 3.5kg of 95% ethanol (mass percentage of ethanol and water) and 1.5kg of propylene glycol were mixed to prepare mixed extractant 2. Add 5kg of mixed extractant 2 to the tobacco raw material flask after the first extraction, heat and stir in a constant temperature oil bath, and extract at a temperature of 80°C for 1 hour, then seal the bottle mouth with a 300-mesh filter cloth, pour it out and collect Extract 2.

[0093] For the third extraction, 1 kg of dist...

Embodiment I

[0096] According to the method of comparative example 1, obtain 5kg of extracting solution, use supercritical carbon dioxide extraction equipment, use 40kg carbon dioxide gas altogether, 2kg ethanol is as entrainer, under the condition of 40 ℃ of extraction kettle pressure, dynamic extraction 2 hours, divide Extraction until all 5kg extracts are used for extraction. The tobacco components were collected and combined in the separatory kettle to obtain about 4.5 kg of tobacco components.

Abstract

The invention relates to a tobacco component suitable for electronic cigarette liquid and its processing and application method, and specifically provides a method for preparing tobacco aroma substances. The method uses a mixed solvent to extract tobacco raw materials in stages; and then mixes the extracts in stages , Concentration, freezing and alcohol precipitation to obtain a clearer extract; finally, purification and separation by supercritical carbon dioxide extraction, finally effectively removing macromolecules such as sugars, enriching the volatile aroma components and latent aroma components of tobacco, the greatest possible Obtained a complete tobacco aroma composition.

Description

technical field [0001] The invention belongs to the technical field of flavoring liquid for electronic smog, and in particular relates to a tobacco component suitable for liquid for electronic smog and a processing and application method thereof. Background technique [0002] With the increasing emphasis on smoking and health issues and the continuous strengthening of tobacco control efforts, the development environment of tobacco products has undergone major and profound changes. New tobacco products such as e-cigarettes and heat-not-burn cigarettes have developed rapidly due to their low harm and environmental impact. According to statistics, in 2017, the global new tobacco product market size was about 17.1 billion US dollars, a year-on-year increase of 38.7%. [0003] In the prior art, propylene glycol and glycerin (glycerol) are mainly used as solvents for the e-cigarette liquid used when smoking e-cigarettes. Traditional cigarette tobacco extract products are used as...
