Problems solved by technology

Among them, the commonly used solvent for the capsule method is medium-chain triglyceride (MCT), which has low polarity, and the commercially available tobacco extract has complex components, including a large amount of macromolecular substances such as sugars and proteins, so it is difficult to extract Soluble in MCT, thus prone to loss of some aroma components
Moreover, these macromolecular substances may affect the plasticity of the tow, make the fibers bond and block the mainstream smoke passage, and affect the fragrance penetration.
[0004] At present, commercially available tobacco extracts are mostly extracted with different concentrations of ethanol as a solvent, but this method has two major disadvantages: ① Some natural aroma components are lost during the extraction process, and the aroma of the product is weak; ② In addition to the aroma components in the product, , as well as pectin, protein,

Embodiment 1

[0031] In this embodiment, the high nicotine tobacco extract is prepared by the following steps:

[0032] 1) Pretreatment: Weigh 1 kg of flue-cured tobacco raw material, place the raw material in a SY-III-A experimental tobacco processor, spray commercially available ammonia water with 2% of the raw material mass, and place it in a sealed place for 12 hours to fully absorb the tobacco leaves, then heat Bake at 60°C for 4 hours;

[0033]2) Pulverize the baked material to 10 meshes, and roll it through a rolling-type wall breaking machine for 3 times to obtain powder;

[0034] Subcritical extraction: add butane (mass ratio 1:8) to the powder, extract at a temperature of 25°C and saturated vapor pressure for 2 hours to obtain an extract;

[0035] The extract is placed in a separation tank, and the solvent is separated by the principle of vacuum evaporation to obtain a crude extract;

[0036] Add 5 times the mass of 95% ethanol to the crude extract while stirring, heat to 50°C a...

Embodiment 2

[0041] In this embodiment, the high nicotine tobacco extract is prepared by the following steps:

[0042] 1) Pretreatment: Weigh 1 kg of flue-cured tobacco raw material, place the raw material in a SY-III-A type experimental tobacco processor, spray a saturated aqueous solution of histidine with a mass of 25% of the raw material, and seal it for 6 hours to make the tobacco leaves fully absorbed. Then heat to 70°C and bake for 5h;

[0043] 2) Pulverize the baked material to 100 mesh, and roll it through a rolling-type wall breaking machine for 3 times to obtain powder;

[0044] Subcritical extraction: add dimethyl ether (mass ratio 1:12) to the powder, extract at a temperature of 45°C and saturated vapor pressure for 0.5h to obtain an extract;

[0045] The extract is placed in a separation tank, and the solvent is separated by the principle of vacuum evaporation to obtain a crude extract;

[0046] Add 10 times the mass of 95% ethanol to the crude extract while stirring, heat ...

Embodiment 3

[0051] In this embodiment, the high nicotine tobacco extract is prepared by the following steps:

[0052] 1) Pretreatment: Weigh 1 kg of flue-cured tobacco raw material, place the raw material in a SY-III-A type experimental tobacco processor, spray 2% lysine saturated aqueous solution of the raw material quality, seal and place for 10 hours, so that the tobacco leaves can be fully absorbed, Then heat to 50°C and bake for 2h;

[0053] 2) Pulverize the baked material to 50 mesh, and roll it through a roller-type wall breaking machine for 3 times to obtain powder;

[0054] Subcritical extraction: add butane (mass ratio 1:10) to the powder, extract at a temperature of 45°C and saturated vapor pressure for 1.5 hours to obtain an extract;

[0055] The extract is placed in a separation tank, and the solvent is separated by the principle of vacuum evaporation to obtain a crude extract;

[0056] Add 8 times the mass of 95% ethanol to the crude extract while stirring, heat to 40°C an...

Abstract

The invention discloses a high-nicotine tobacco extract and application thereof, and belongs to the field of tobacco additives. The extract is rich in aroma components such as megastigmatrienone, damascone, pyrones and furanones in tobacco, can provide tobacco aroma and roasting aroma, further contains certain nicotine, can cater for physiological needs of consumers, and improves satisfaction. Content of macromolecular substances such as proteins, pectin and polysaccharides in the extract is extremely low, solubleness is good, the high-nicotine tobacco extract can be completely dissolved into MCT (medium chain triglyceride), and can be used for perfuming a filter tip. Besides, the high-nicotine tobacco extract is added into cut stems or reconstituted tobaccos, so that stimulus can be reduced, strength is improved, a blending rate, in a tobacco group, of the cut stems or reconstituted tobaccos is increased, and content of cigarette tar is reduced while fragrance is invigorated and impurities are covered.

Description

technical field [0001] The invention relates to a high-nicotine tobacco extract and the application of the extract, belonging to the field of tobacco additives. Background technique [0002] Tobacco stems, the main veins of tobacco leaves, account for about 25% to 30% of the weight of tobacco leaves. my country is a big tobacco producing country, producing about hundreds of thousands of tons of tobacco stems every year. Among them, some tobacco stems are manufactured by expansion technology into expanded stems and added to the leaf group formula, and some tobacco stems and waste tobacco leaves (fragments, tobacco powder) are added with wood pulp as raw materials to make reconstituted tobacco leaves. Using a certain proportion of expanded cut stems and reconstituted tobacco leaves in the cigarette leaf group formula can reduce the tar release and increase the filling value of cigarettes. However, shredded stems and reconstituted tobacco leaves have heavy miscellaneous gases...
