Problems solved by technology

However, while the amount of tar in cigarettes is reduced, the amount of aroma in the smoke is also reduced, resulting in insufficient "taste" and "aroma" of cigarettes.

Embodiment 1

[0020] Process for the preparation of tobacco extracts, including pretreatment, supercritical CO 2 Extraction, cellulose extraction, fermentation and vacuum freeze drying. The fermentation step is in supercritical CO 2 Add potato liquid and active protein to the extracted nicotine, stir evenly, and inoculate yeast Saccharomyces fornicata, ferment for 2 hours with oxygen, ferment with anaerobic for 24 hours, microfiltration and ultrafiltration, and take the filtrate. The content of solanesol in the nicotine extract increased significantly after aerobic and anaerobic fermentation by Saccharomyces fornicatus, but the specific fermentation mechanism was not clear. Dilute the tobacco extract with ethanol and isopropanol, and add it to cigarettes at a mass fraction of 0.002%, which can significantly improve the aroma of the cigarette, making the smoke pure and round, and the aroma of the cigarette refreshing.

[0021] The pretreatment step is to take tobacco with a particle size o...

Embodiment 2

[0030] The most preferred preparation method of tobacco extract, comprises the following steps:

[0031] 1) Pretreatment: Take tobacco with a particle size of 70 mesh, soak it in an aqueous medium for 10 hours, perform steam explosion treatment, and dry it to obtain a tobacco pretreatment material. The moisture content of the tobacco pretreatment material is 4%;

[0032] 2) Supercritical CO 2 Extraction: Carry out supercritical extraction treatment on the tobacco pretreatment material, the extraction temperature is 46°C, the extraction pressure is 34MPa, and the extraction time is 2.7h; the pressure of the separation tank I is 7MPa, and the temperature is 47°C; the pressure of the separation tank II is 5MPa, and the temperature is 21°C. The entraining agent is methanol and 3% ethyl acetate with a mass fraction of 4.5%;

[0033] 3) Cellulose extraction: in supercritical CO 2 Add 1-butyl-3-methylimidazolium chloride salt equivalent to 17 times the mass of tobacco residue to th...

Embodiment 3

[0037] The preparation method of tobacco extract comprises the following steps:

[0038] 1) Pretreatment: Take tobacco with a particle size of 60 mesh, soak it in an aqueous medium for 12 hours, perform steam explosion treatment, and dry it to obtain a tobacco pretreatment material, and the moisture content of the tobacco pretreatment material is 5%;

[0039] 2) Supercritical CO 2 Extraction: Tobacco pretreatment material is subjected to supercritical extraction treatment, the extraction temperature is 45°C, the extraction pressure is 33MPa, and the extraction time is 3h; the pressure of the separation kettle I is 6.7MPa, and the temperature is 46°C; the pressure of the separation kettle II is 4.3MPa, and the temperature is 22°C. The entrainer is methanol and 3.8% ethyl acetate with a mass fraction of 4.8%;

[0040] 3) Cellulose extraction: in supercritical CO 2 Add 1-butyl-3-methylimidazolium chloride salt equivalent to 18 times the mass of tobacco residue to the tobacco re...

Abstract

The invention discloses a preparing method of a tobacco extract. The preparing method comprises the steps of pretreatment, supercritical CO2 extraction, cellulose extraction, fermentation and vacuum freezing and drying. The preparing method of the tobacco extract has the advantages that nicotine extracted through the method is high in purity and high in extracting rate and doped with few volatilearomatic components, and the finally obtained tobacco extract is very low in tar content and has characteristic aroma of tobacco. After aerobic and anaerobic fermentation through saccharomycopsis fibuligera, the content of solanesol in the nicotine extract is obviously increased, but the specific fermentation mechanism is not explicit. Ethyl alcohol and isopropyl alcohol are utilized to dilute thetobacco extract and are added into cigarettes according to the mass percentage of 0.001%-0.003%, the tobacco aroma can be obviously improved, so that smoke is pure and tender, and the tobacco aroma is good.

Description

technical field [0001] The invention relates to the field of extraction of plant components, in particular to a preparation method of tobacco extract. Background technique [0002] my country is a big tobacco-producing country. Not only a large amount of tobacco waste such as tobacco dust, tobacco residue, tobacco stems, polluted or moldy tobacco leaves is produced during the storage and transportation of tobacco leaves and cigarette production, but also the low-grade tobacco leaves that tobacco farmers discard in the fields every year The number is also considerable. Tobacco leaves contain a variety of valuable chemical components. If they are used comprehensively, it will not only improve the pollution of waste to the environment, but also create wealth for the country. However, due to the backward technological conditions and high product cost, the market competitiveness is not high and the comprehensive utilization efficiency is low. [0003] tobacco( Nicotianatobaculn...
