Description
?
Technical field
The invention belongs to technical field of tobacco, be specifically related to a kind of tobacco-containing material preparation method who is applicable to heat non-burning type tobacco product.
Background technology
Heat non-burning type tobacco product and originate from the eighties in last century, from product, emerge and have so far the history of nearly 30 years.Through continuous technological innovation and product promotion, become one of important kind of novel tobacco goods.Flue gas and traditional cigarette that this series products produces are comparatively approaching, and side-stream smoke and part harmful components obviously reduce, and make it have certain market potential, thereby correlation technique have become the focus that foreign tobacco company is studied at present.In the last few years, along with continuing to increase of Tobacco Control dynamics, foreign tobacco company will heat non-burning type tobacco product and continue to increase R&D intensity as the substituting product of traditional cigarette, and start to promote to publilc health department and worldwide consumer, this has also caused that international Field of Tobacco is to heating the extensive concern of non-burning type tobacco product, and it is defined as to " real harm reduction product ".
The technological core that heats non-burning type tobacco product mainly concentrates on thermal source and two aspects of cigarette core.According to the characteristics of correlation technique, the thermal source type is divided into electric heating type, thermal source hot type and chemical reaction hot type, and wherein the first two thermal source has been applied to product, as " Accord " of Fei Mo tobacco company and " Eclipse " of company of R. J. Reynolds Tobacco.The cigarette core is as one of core technology that heats non-burning type tobacco product, the tobacco-containing material that its design adopts at present mainly contains pipe tobacco, offal, reconstituted tobacoo, tobacco extract etc., and what relevant patent related generally to is combination and the corresponding product structure design mode of multi-form tobacco-containing material.Yet, for the cigarette core, the preparation of tobacco-containing material processing is very crucial, directly affects the cigarette core and heat the flue gas release characteristic under non-fired state, and then determine cigarette core and the design feature of heating element heater and the quality of product.But may be for the reason of technical know-how, relevant research and concrete technology rarely have report abroad.By the anatomy to existing product, find, this series products heating is lower can effectively discharge the flue gas with tobacco characteristic chicken flavor, after heating, obvious charing phenomenon has appearred in tobacco-containing material, but burning has to a certain degree also occurred, illustrate that existing product also need further optimize aspect fire-retardant, could really accomplish that tobacco-containing material is to discharge flue gas under the on-fuel state of heating.Therefore, inventing and a kind ofly can effectively improve the preparation method that tobacco-containing material heats the flue gas release performance under non-fired state, is very significant for the exploitation of the non-burning type tobacco product of heating.
Summary of the invention
Purpose of the present invention provides a kind of tobacco-containing material preparation method who is applicable to heat non-burning type tobacco product for the existing problem of above-mentioned prior art just, and the tobacco-containing material that adopts the present invention to prepare can effectively discharge the flue gas with tobacco characteristic chicken flavor under the non-fired state of heating.
The objective of the invention is to be achieved through the following technical solutions
A kind of tobacco-containing material preparation method who is applicable to heat non-burning type tobacco product comprises the following steps successively:
(1) raw tobacco material (can be blade, pipe tobacco or powder) is carried out to lixiviate with ethanol water, prepare tobacco extract.The mass ratio of tobacco leaf and ethanol water is 1:5～1:20, and the concentration of ethanol water is 40 %～90 %, and extraction temperature is 20 ℃～80 ℃, and extraction time is 12 h～72 h.
(2) after lixiviate finishes, solution is separated with tobacco leaf, obtain tobacco extract.After this extract evaporation under reduced pressure is removed to ethanol, freeze drying obtains the solid tobacco extract, and the productive rate that the raw tobacco material butt of take calculates is 30 %～70 %.This solid tobacco extract is mainly volatilization in tobacco leaf and half volatile ingredient and water-soluble sugar, amino acid etc.
(3) by the solid tobacco extract with after thering is the metal hydroxide particle mixing of fire retardation, add appropriate solvent fully to disperse to form mixture of viscous form.Adopt cylinder drying to carry out drying resulting mixture of viscous form, material drying obtains being applicable to heat the tobacco-containing material of non-burning type tobacco product after pulverizing.The mass ratio of solid tobacco extract and metal oxide is 1:0.3～1:5, and solvent is water, ethanol or ethanol water, and the mass ratio of solvent and solid material is 0.5:1～3:1, and the particle diameter of metal hydroxide particle is 1 μ m～200 μ m.
According to the requirement to prepared tobacco-containing material sense organ style and features, raw tobacco material of the present invention can be one or more mixing of the dissimilar tobacco leaves such as flue-cured tobacco, burley tobaccos, Turkish tobaccos.Metal hydroxides with fire retardation of the present invention can be Mg (OH)
2, Al (OH)
3, Fe (OH)
3, Cu (OH)
2deng one or more mixing.
Advantage of the present invention:
The present invention by the ethanol water extraction get, the treatment step such as ethanol removal, freeze drying, the cellulose in the tobacco leaf, hemicellulose, lignin etc. have effectively been removed flammable and produce the macromolecular substances of bad breath under heating condition, the flavor precursors such as the volatilization that the solid tobacco extract obtained is mainly and half volatile ingredient and water-soluble sugar, amino acid, under heating condition, can directly volatilize or be subject to thermal response after discharge the flavor characteristics of tobacco flue gas.
2. the tobacco-containing material that prepared by the present invention can effectively discharge flue gas under the non-fired state of heating.Thermogravimetric analysis shows, the thermal weight loss rate of tobacco-containing material under 300 ℃ that adopts the present invention to prepare is 20 %～70 %, possesses the ability of effective release flue gas.Sensory evaluation shows, the tobacco-containing material that adopts the present invention to prepare heats the flue gas discharged and all has good satisfaction aspect concentration and strength under 200 ℃～400 ℃, and flavouring essence quality and the sense organ comfortableness also better.
3. Mg of the present invention (OH)
2, Al (OH)
3, Fe (OH)
3, Cu (OH)
2there is good fire retardation Deng metal hydroxides, be subject to can effectively absorb heat in thermal process at tobacco-containing material, thereby guarantee that prepared material is to discharge flue gas under the on-fuel state of heating.The metal hydroxides adopted will dewater after absorbing heat, therefore by the release of moisture, will be conducive to the release of tobacco-containing material flue gas under the on-fuel state of heating, and the organoleptic quality of discharged flue gas is also had to positive effect.In addition, for Cu (OH)
2, due to Cu
2+there is good complexing with cyanide ion, carbonyl, therefore, Cu (OH)
2the burst size to reducing the harmful components such as hydrogen cyanide, volatility carbonyl compound in flue gas that adds certain effect is also arranged.
4. preparation technology of the present invention is simple, cost is low, has good industrial prospect.
