Embodiment 1

[0021] The tobacco extract comprises the following components and parts by weight: 6.6 parts of nicotine, 1.0 part of volatile aromatic components and 80 parts of cellulose powder.

[0022] 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 i...

Embodiment 2

[0032] The tobacco extract comprises the following components and their most preferred parts by weight: 7.5 parts of nicotine, 0.2-1.3 parts of volatile aromatic components and 90 parts of cellulose powder.

[0033] The most preferred preparation method of tobacco extract, comprises the following steps:

[0034] 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%;

[0035] 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 a...

Embodiment 3

[0040] The tobacco extract comprises the following components and parts by weight: 8.0 parts of nicotine, 0.2-1.3 parts of volatile aromatic components and 96 parts of cellulose powder.

[0041] The preparation method of tobacco extract comprises the following steps:

[0042] 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%;

[0043] 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 f...

Abstract

The invention discloses a preparation method of a tobacco extract. The method comprises the steps of preprocessing, supercritical CO2 extracting, cellulose extracting, fermenting and vacuum freeze drying. The tobacco extract has the advantages that by adopting the method, the extracted nicotine purity is high, the extracting rate is high, only a small number of volatile aroma constituents are mixed, and finally the obtained tobacco extract is quite low in tar content and has the characteristic aroma. After aerobic and anaerobic fermentation of saccharomycopsis fibuligera is performed, the content of solanesol in the nicotine extract is obviously increased, and the specific fermentation mechanism is not clear. Ethyl alcohol and isopropanol are used for diluting the tobacco extract and added into cigarettes according to the mass fraction of 0.001-0.003%, the cigarette fragrance can be obviously improved, the smoke is pure, mellow and full, and the cigarette fragrance is tasty and refreshing.

Description

technical field [0001] The invention relates to the field of extraction of plant components, in particular 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 ) is a plant of the genus ...
