Description
Technical field
The invention belongs to technical field of tobacco, specifically the preparation method of a kind of low albumen tobacco extract for novel tobacco and application.
Background technology
In recent years, along with the propelling of level on Medicated cigarette, reducing the coke tar in cigarette amount of releasing and put the jealous deficiency of the Nicotiana tabacum L. brought, it is tobacco business problem demanding prompt solution that gratification weakens.
Tobacco extract is a kind of dark brown viscous mastic, can be used for increase Nicotiana tabacum L. nature fragrance in tobacco essence, improves Nicotiana tabacum L. suction quality.At present, traditional method be by tobacco material through polar solvent extract after be condensed into cream or by Aqueous extracts through precipitate with ethanol process after take clear liquid concentration obtain prepared opium paste, it is general that similar technique extracts the general quality of prepared opium paste obtained, there is contained aroma component relative amount in prepared opium paste not high, solvent consumption is relatively big and has the problems such as residual, it is impossible to meet the demand that tobacco industry develops further.Can provide for the highly desirable related researcher of this tobacco business that more can to improve Nicotiana tabacum L. jealous, increase the tobacco extract product of Nicotiana tabacum L. inherent feature fragrance, promote the sustainable development of tobacco industry.
Protein tobacco is as what the growth promoter of Nicotiana tabacum L. built up, and as the exploitation of edible protein resource, tobacco protein has its positive role, and the impact for Nicotiana tabacum L. sucking quality then needs to should be regarded as a different matter.Cured tobacco leaf protein content after ovennodulation is typically in about 8%.In tobacco product, focus on tobacco aroma and inhale taste, and protein content is too high, then fragrance and jealous variation, produces acid, bitterness and zest.
Summary of the invention
For the deficiencies in the prior art, it is jealous that the present invention provides one to improve Nicotiana tabacum L., increases the tobacco extract of Nicotiana tabacum L. inherent feature fragrance, further isolates the tobacco extract of low-protein from tobacco extract.
Technical scheme provided by the invention: the preparation method of a kind of low albumen tobacco extract for novel tobacco, comprises the steps:
(1) with Nicotiana tabacum L. for raw material, carry out pulverization process, add mass fraction 60%～95% ethanol, heating in water bath reflux, extract, 2～4h at 65 DEG C～85 DEG C according to the ratio of feed liquid mass ratio 1:4～1:8, after filtration, solvent is removed in filtrate concentration, obtain Nicotiana tabacum L. concentrate；
(2) the Nicotiana tabacum L. concentrate of step (1) gained sodium hydroxide solution is regulated pH value 7.0, add 5.0g/L neutral protease and at 40 DEG C～55 DEG C water-bath 3～4h, after concentration, prepare the tobacco extract after neutral protease enzymolysis；
(3) being positioned in vacuum distillation equipment by the tobacco extract of step (2) gained, tobacco extract carries out decompression distillation, is slowly heated, system pressure is 1～5mmHg, collects the fraction B of less than 200 DEG C fraction A and 200 DEG C～300 DEG C respectively.
Further, described tobacco material is flue-cured tobacco, Turkish tobaccos, dry in the sun cigarette, burley tobaccos, cigar, Nicotiniana rustica.
Another kind of technical scheme provided by the invention: the application of a kind of low albumen tobacco extract, the fraction A prepared according to above-mentioned preparation method and fraction B are taken mass ratio is 5:2～5:7, after adding the propylene glycol dissolving of distillation weight 6～8 times, add in new cigarette tobacco product.
Further, described new cigarette tobacco product includes electrical heating new cigarette, carbon heating new cigarette, electronic cigarette, Folium Nicotianae preparatum and Nicotiana tabacum L. spray product.
Beneficial effects of the present invention: (1) adopts enzymatic isolation method can remove the protein in Nicotiana tabacum L. comparatively up hill and dale, reduces the protein impact on tobacco extract perfuming effect, and protein content is low, the good tobacco extract of perfuming effect thus obtaining；(2) tobacco extract being undertaken extracting by distillation of reducing pressure, reduces the impact of Nicotiana tabacum extract macromolecular substances；(3) characteristic according to kinds of cigarettes goods, will extract tobacco extract and be applied to novel tobacco goods, and the characteristic perfume making Nicotiana tabacum L. is more readily apparent, improve the acceptable degree of novel tobacco goods.
Detailed description of the invention
Below in conjunction with specific embodiment, the technical scheme in the present invention is clearly and completely described.Should be appreciated that the specific embodiment described by this part can only be used to explain the present invention, be not intended to limit the present invention.
Embodiment one
Take the burley tobaccos Nicotiana tabacum L. after 500g pulverizes, the ethanol 2000mL of addition 75% is heated to reflux 3h at 80 DEG C and extracts, after filtration, solvent is removed in filtrate concentration, burley tobaccos Nicotiana tabacum L. concentrate is obtained after concentration, after burley tobaccos extract is regulated pH value 7.0 with sodium hydroxide, it is added thereto to 5.0g/L neutral protease and at 40 DEG C of water-bath 4h, after concentration, prepares the Bailei tobacco extract after neutral protease enzymolysis.
Taking Bailei tobacco extract, be positioned in vacuum distillation equipment, concentrate carries out decompression distillation, is slowly heated, system pressure is 1mmHg, collects the fraction B of less than 200 DEG C fraction A and 200 DEG C～300 DEG C respectively.Taking mass ratio is fraction A: the distillation 1g of fraction B=5:4, with 6g propylene glycol dissolve after, add in electrical heating new cigarette tobacco product prepared by thin slice, it is possible to reduce to the stimulation of throat, miscellaneous QI reduce, cigarette perfume (or spice) more rich.
