Description
Technical field
The invention belongs to Field of Tobacco, and in particular to a kind of preparation method of tobacco curing straw-made articles again and contain tobacco curing grass system again
The composition of product.
Background technique
Chewing tobacco, buccal cigarette, snuff, electric heating type tobacco product, fuel hot type tobacco product, tobacco spray product at present
And electronic cigarette etc. includes the product of tobacco material, there is common, i.e. a taste and traditional cigarette or cigar
Taste differs greatly, it is difficult to consumer be allowed to approve.Simultaneously tobacco extract fragrance also with the cigarette of extracting combustion or cigar
Taste differ greatly, it is difficult to chewing tobacco, buccal cigarette, snuff, electric heating tobacco product, fuel hot type tobacco product, cigarette
The products such as careless spray product and electronic cigarette provide the fragrance such as sufficient burnt odor, Jiao Tianxiang, faint scent, fresh and sweet perfume, radix aucklandiae.
Currently, the approach that the taste of each research team's solution taste and cigarette or cigar differs greatly, it is each to concentrate on addition
Kind natural flavor substance, it is expected the taste for achieving the purpose that imitate cigarette or cigar, but the side of addition fragrance matter at present
Method is still difficult to the taste for achieving the purpose that imitate cigarette or cigar.In addition, there is some tobacco products flavor component to be difficult to hold
Long defect.
Summary of the invention
For the deficiency of this field research aspect, the purpose of the present invention is to propose to a kind of preparation methods of tobacco extract.
It is another object of the present invention to propose tobacco extract made from the preparation method.
Third object of the present invention is the composition for proposing to contain the tobacco extract.
Realize the technical solution of the object of the invention are as follows:
A kind of preparation method of tobacco extract, comprising the following steps:

One of carbon dioxide of state is a variety of；
2) step 1) products therefrom is to heat at a temperature of between 100~500 DEG C in temperature, and the heating is to contain nitrogen
It is carried out in the atmosphere of gas, the atmosphere is that 100 nitrogen and 0~10 part of air and/or oxygen form by volume parts.
Wherein, the tobacco material be tobacco crude extract, pipe tobacco, tobacco leaf, tobacco extract, vacuum distillation tobacco extract obtain
Distillate, the difficult volatile materials that vacuum distillation tobacco extract obtains, short-path distillation tobacco extract distillate, short
Journey distills one of difficult volatile materials of tobacco extract or a variety of.
Specifically, the tobacco crude extract is that Tobacco Leaf and/or stem shred after 50-180 DEG C of drying, and ethyl alcohol, water is added
One of or it is a variety of, additional amount is 1~10 times of Tobacco Leaf and/or stem quality, and institute is concentrated under reduced pressure after impregnating 0.5-50 hours
?.The tobacco leaf can be tobacco leaf powder and/or sheet tobacco leaf.
Wherein, in the step 1), tobacco material is placed in the ethyl alcohol that mass fraction is 40~98% and extracts under room temperature, cigarette
The mass volume ratio of grassland material and ethyl alcohol is 1g:1~10mL；Extraction time is 2.5-3.5 hours preferred, tobacco material and ethyl alcohol
Mass volume ratio is preferably 1g:4~8mL.
Or: tobacco material is first placed in the hydrochloric acid solution that mass fraction is 1~2% 0.5~2 hour, is washed out, then set
Extracted under room temperature in the ethyl alcohol that mass fraction is 40~98%, the mass volume ratio of tobacco material and ethyl alcohol be 1g:1~
10mL；Preferably, it is extracted 2.5-3.5 hours under room temperature, the mass volume ratio of tobacco material and ethyl alcohol is 1g:4~8mL.
Or, tobacco material is placed in the ethyl alcohol that mass fraction is 90~98% ultrasonic extraction under room temperature in the step 1),
The mass volume ratio of tobacco material and ethyl alcohol is 1g:1~10mL；Preferably ultrasonic extraction 2.5-3.5 hours, tobacco material and second
The mass volume ratio of alcohol is 1g:4~8mL.
Or, the ethyl alcohol that mass fraction is 90~98% is added in tobacco material in the step 1), extracted in 38~45MPa
Carbon dioxide draw is used under pressure, 48~55 DEG C of extraction temperatures；The mass volume ratio of tobacco material and ethyl alcohol be 100g:1~
15mL；Preferably 100g:4~8mL.The time extracted with carbon dioxide (being supercritical carbon dioxide under the state)
Preferably 0.5-3.5 hours.
Preferably, in the step 2), step 1) products therefrom is initial temperature is 100~200 DEG C, final temperature is
It is heated at a temperature of 400~500 DEG C, heating rate is 0.1~6 DEG C/min.Preferably heating rate is 4~6 DEG C/min

Cigarette, snuff, electric heating type tobacco product, fuel hot type tobacco product, tobacco spray product, chewing gum, reconstituted tobacoo and electricity
One of sub- cigarette.
Tobacco extract proposed by the present invention, application mode is including but not limited to perfuming cigarette, cigarette filter flavoring, again
The charging of tobacco is made, material with slow-release function is prepared into using porous material absorption, not burning perfuming cigarette and is used as electricity
Sub- cigarette raw material.
Wherein, the reconstituted tobacco feeds, and refers in the process for preparing reconstituted tobacco using rolled-on method or paper process,
Tobacco extract is added or is applied to finished product or semi-finished product reconstituted tobacco；The reconstituted tobacco, application comprising but it is unlimited
In the tobacco-containing material for being used as cigarette composition, electric heating type tobacco product and fuel hot type tobacco product.
Wherein, the composition further include porous-starch, titanium dioxide, calgon, expanded cut tobacco, expanded cut stem,
One of ethyl alcohol, water, ethylene glycol, glycerol, rapeseed oil, palm oil, corn oil, calcium carbonate, surfactant are a variety of.
Specifically, the surfactant is selected from sorbierite, potassium citrate and guar gum, Sodium Polyacrylate, polypropylene
One of sour ammonium, polyvinylpyrrolidone and sodium alginate or two or more mixtures.
Further, tobacco extract and glycerol, propylene glycol, water are mixed according to mass ratio 0.2~0.4:4:5:0.5~0.8
Close uniformly to get arrive tobacco juice for electronic smoke.
Tobacco extract by mass fraction 4~6% addition obtain coating fluid, further include in coating fluid mass content be 20~
50% calcium carbonate, 0.3~0.6% calgon, 0.1~0.3% Sodium Polyacrylate and surplus water.
Tobacco extract and porous-starch are uniformly mixed according to mass ratio 3:6~8, and are sealed 2 days to get to having
The material of slow-release function；The obtained material with slow-release function is added in 20g chewing gum base rubber, chewing gum is made.
The beneficial effects of the present invention are:
The present invention can be well solved current chewing tobacco, buccal cigarette, snuff, electric heating type tobacco product, fuel hot type cigarette
The taste problem of the products such as straw-made articles, tobacco spray product and electronic cigarette, and the fragrance of some products can also be improved well
Unendurable defect.
The preparation method and application of tobacco extract provided by the invention, by by tobacco material under gas atmosphere,
Processing in certain temperature range, obtained tobacco extract have the characteristic richer compared with fragrance before handling, apply it to and chew
Cigarette, buccal cigarette, snuff, electric heating type tobacco product, fuel hot type tobacco product, tobacco spray product and electronic cigarette etc., can
So that these products are largely close with traditional cigarette taste.It is right when the tobacco extract matter is used as perfuming cigarette
Flue gas has the effects that increase solid sense, fine and smooth flue gas, abundant cigarette perfume.
The time that different tobacco materials are kept is generally at 1 minute to 5 hours, and the preferred time of different tobacco materials is not
Together, it is slightly different with the tobacco material after different heating temperatures, sequence, time-triggered protocol, but characteristic chicken flavor is almost the same, thus
The diversity of product can be enriched.
