Description
Technical field
The invention belongs to technical field of tobacco, be specifically related to a kind of tobacco-containing material preparation method being applicable to heat non-combustion-type tobacco goods.
Background technology
Heating non-combustion-type tobacco goods originate from the eighties in last century, the history emerged from product existing nearly 30 years so far.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 close, and side-stream smoke and part harmful components obviously reduce, and make it have certain market potential, thus correlation technique has 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 continues to increase R&D intensity using heating the substituting product of non-combustion-type tobacco goods as traditional cigarette, and start to promote to publilc health department and worldwide consumer, this also result in the extensive concern of international Field of Tobacco to heating non-combustion-type tobacco goods, and is defined as " real harm reduction product ".
The technological core of heating non-combustion-type tobacco goods mainly concentrates on thermal source and cigarette core two aspects.According to the feature of correlation technique, heat source is divided into electric heating type, heat source type and chemical reaction hot type, and wherein first two thermal source is applied to product, as " Accord " of Fei Mo tobacco company and " Eclipse " of Reynolds Tobacco Company.Cigarette core is as one of core technology heating non-combustion-type tobacco goods, it designs the tobacco-containing material adopted and mainly contains pipe tobacco, offal, reconstituted tobacoo, tobacco extract etc. at present, and what RELATED APPLICATIONS related generally to is the combination of multi-form tobacco-containing material and corresponding product structure design mode.But for cigarette core, the preparation of tobacco-containing material processing is very crucial, directly affect cigarette core heat non-burning state under flue gas release characteristic, and then decision cigarette core and the design feature of heating element heater and the quality of product.But may for the reason of technical know-how, relevant research and concrete technology rarely have report abroad.By finding the anatomy of existing product, the heating of this series products is lower effectively can discharge the flue gas with tobacco characteristic chicken flavor, after heating there is obvious charing phenomenon in tobacco-containing material, but the burning that also there occurs to a certain degree, illustrate that existing product also need be optimized further in fire-retardant, really could accomplish that tobacco-containing material discharges flue gas under the on-fuel state of heating.Therefore, invent a kind of preparation method of the flue gas release performance that can effectively improve under tobacco-containing material heating non-burning state, the exploitation for heating non-combustion-type tobacco goods is significantly.
Summary of the invention
Object of the present invention provides a kind of tobacco-containing material preparation method being applicable to heat non-combustion-type tobacco goods just for problem existing for above-mentioned prior art, the tobacco-containing material adopting the present invention to prepare can effectively discharge the flue gas with tobacco characteristic chicken flavor under heating non-burning state.
The object of the invention is to be achieved through the following technical solutions
Be applicable to the tobacco-containing material preparation method heating non-combustion-type tobacco goods, comprise the following steps successively:
(1) raw tobacco material (can be blade, pipe tobacco or powder) is carried out 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 DEG C ~ 80 DEG C, and extraction time is 12 h ~ 72 h.
(2) after lixiviate terminates, solution is separated with tobacco leaf, obtains tobacco extract.After this extract evaporation under reduced pressure removing ethanol, freeze drying obtains solid tobacco extract, is 30 % ~ 70 % with the productive rate that raw tobacco material butt calculates.This solid tobacco extract is mainly volatilization in tobacco leaf and half volatile ingredient and water-soluble sugar, amino acid etc.
(3), after solid tobacco extract and the metal hydroxide particle with fire retardation being mixed, add appropriate solvent and fully disperse to form mixture of viscous form.Adopt cylinder drying to carry out drying obtained mixture of viscous form, material drying obtains the tobacco-containing material being applicable to heat non-combustion-type tobacco goods after pulverizing.The mass ratio of solid tobacco extract and metal hydroxides 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 μm ~ 200 μm.
According to the requirement to prepared tobacco-containing material sense organ style and features, raw tobacco material of the present invention can be the mixing of one or more of the dissimilar tobacco leaves such as flue-cured tobacco, burley tobaccos, Turkish tobaccos.The metal hydroxides with fire retardation of the present invention can be Mg (OH)
2, Al (OH)
3, Fe (OH)
3, Cu (OH)
2deng the mixing of one or more.
Advantage of the present invention:
1. the present invention got by ethanol water extraction, ethanol removal, the treatment step such as freeze drying, effectively eliminate the cellulose in tobacco leaf, hemicellulose, lignin etc. flammable in a heated condition and produce the macromolecular substances of bad breath, the solid tobacco extract obtained volatilization mainly and half volatile ingredient and the flavor precursor such as water-soluble sugar, amino acid, directly can volatilize in a heated condition or discharge the flavor characteristics of tobacco flue gas by after thermal response.
2. the tobacco-containing material that prepared by the present invention effectively can discharge flue gas under heating non-burning state.Thermogravimetric analysis shows, the thermal weight loss rate of tobacco-containing material at 300 DEG C adopting the present invention to prepare is 20 % ~ 70 %, possesses the ability of effectively release flue gas.Sensory evaluation shows, adopts the tobacco-containing material prepared of the present invention at 200 DEG C ~ 400 DEG C, heat the flue gas discharged and all have good satisfaction in concentration and strength, and flavouring essence quality and sensory comfort also better.
3. Mg of the present invention (OH)
2, Al (OH)
3, Fe (OH)
3, Cu (OH)
2deng metal hydroxides, there is good fire retardation, effectively can absorb heat in tobacco-containing material thermal histories, thus the material prepared by ensureing discharges flue gas under the on-fuel state of heating.The metal hydroxides adopted will dewater after absorbing heat, therefore will be conducive to the release of tobacco-containing material flue gas under the on-fuel state of heating by the release of moisture, and also has positive effect to the organoleptic quality of discharged flue gas.In addition, for Cu (OH)
2, due to Cu
2+with cyanide ion, carbonyl, there is good complexing, therefore, Cu (OH)
2add and also have certain effect to reducing the burst size of the harmful components such as hydrogen cyanide, volatile carbonyl thing in flue gas.
4. preparation technology of the present invention is simple, cost is low, has good industrial prospect.
