Above-mentioned purpose of the present invention is achieved by following scheme:
The invention provides a kind of preparation method of reconstituted tobacoo, this method adopts existing traditional paper process, with tobacco (as offal, the offal etc.) extraction that is soaked in water, through squeeze and filter, after the Separation of Solid and Liquid, solid is made sheets of fibres sheet base, liquid concentration is made coating fluid, and coating fluid is applied on the sheets of fibres sheet base, and the section of oven dry back prepares reconstituted tobacoo, but be that with existing traditional paper process difference preparation method of the present invention also comprises following two steps operation:
(1) enzyme is joined in the tobacco soak, tobacco is carried out enzyme handle;
(2) with after the liquid concentration, in concentrate, add reduced sugar and amino acid earlier, make concentrate generation Maillard reaction, prepare coating fluid, again this coating fluid is applied to sheets of fibres sheet base.
Above-mentioned employing enzyme is handled tobacco, mainly be the consumption of selecting suitable enzyme and definite enzyme suitable, by enzymolysis the macromolecular compound in the tobacco transformed as much as possible and be degraded to micromolecular compound, can reduce the assorted gas content of reconstituted tobacoo, thereby improve the interior quality of reconstituted tobacoo; Described complex enzyme can be selected a kind of or two or more arbitrarily in compound protease, compound pectinase, neutral cellulase, zytase or the carbohydrase; Described compound protease, compound pectinase, neutral cellulase, zytase or carbohydrase all have sale of finished goods, can buy from market to obtain.
Maillard reaction is a kind of carbonyl-amino reaction, this reaction can cause the change of material color and luster, produce fragrance simultaneously, but prior art is not seen the technology report that utilizes Maillard reaction to improve tobacco aroma or obtain the different flavor reconstituted tobacoo by change Maillard reaction condition, the present invention introduces Maillard reaction among the tobacco sheets by paper making method preparation technology, utilizes the fragrance that enzyme is handled and Maillard reaction is produced to give reconstituted tobacoo strong fragrance.And sum up suitable and accurate Maillard reaction condition by long-term a large amount of experimental study, obtain more excellent product quality; By determining that adding different reaction material (different reduced sugars and amino acid) in concentrate carries out the technical scheme that Maillard reaction produces expection fragrance, adapts to the requirement of different-style cigarette product.
Among the above-mentioned preparation method, the mixture of preferred offal of tobacco and offal is by the be improved good result of qualities such as reconstituted tobacoo fibre plate base and fragrance of the different processing scheme of offal and offal collocation.
The main component that comprises in the tobacco that the present invention adopts is offal and offal, offal mainly contains fibrous matter and pectin, sugar, starch and a small amount of aroma component, contain a large amount of aroma components and fibrous matter in the offal, in present tobacco production plant, because offal and offal go out of use need not, so cause that fibrous matter, aroma component etc. can not be fully utilized in the tobacco leaf; Simultaneously, because offal and offal institute fibrous substance, aroma component are different, so the present invention separately handles two kinds of materials, determines different processing schemes, pointedly the utility in two kinds of materials is fully extract, and search out the blend proportion of the two comparative optimization.
Preparation method of the present invention specifically comprises the steps:
(1) with being soaked in water after the offal polishing peeling, obtains the offal soak, in this offal soak, add enzyme, extract after the enzymolysis processing;
Offal is soaked in water, obtains the offal soak, in this offal soak, add enzyme, extract after the enzymolysis processing;
(2) step (1) extract is carried out successively squeeze and filter, Separation of Solid and Liquid processing respectively;
(3) step (2) offal is handled separating obtained solid, offal is handled separating obtained solid and is scattered in respectively in the water, fibre is separated in making beating, separates to remerge behind the fibre and joins slurry, fiber brooming gets baccy fiber, makes sheets of fibres sheet base after baccy fiber dehydrates;
The separating obtained liquid of combining step (2), concentrate concentrate, in concentrate, add reduced sugar and amino acid, make concentrate carry out Maillard reaction, prepare coating fluid;
(4) step (3) preparation gained coating fluid is applied on the sheets of fibres sheet base, obtains reconstituted tobacoo after the drying.
Among the above-mentioned preparation method, the polishing of described offal peeling is soaked in water, offal is soaked in water, extraction, squeeze and filter extract, Separation of Solid and Liquid is handled and baccy fiber made basic operation such as sheets of fibres sheet base can be with reference to conventional producing tobacco flake in method similar to papermaking method, for example extraction can adopt the extraction of common process single, routine repeatedly to extract and Continuous Countercurrent Extraction.But as preferred, three stage countercurrent pot type extraction processes are adopted in extraction of the present invention, each part tobacco (offal or offal) is carried out three times extract, and use secondary raffinate, extract and water as extractant successively; Each portion extractant extracts three parts of stalks; be respectively second extraction stalk or end, once extract stalk or end and new stalk or end; promptly water soluble ingredient in the material is extracted fully, can not propose new specific (special) requirements again, the recovery rate of single-stage extraction technology 35% can be brought up to 50% equipment.Extraction temperature is preferably 50 ℃～80 ℃, and the extraction time is 30～60min, can guarantee the extraction of solable matter, reduces energy resource consumption again, and effectively avoids the loss of fragrance component, keeps the quality of papermaking-method reconstituted tobaccos product.In order to screen the proportioning of determining tobacco and aqueous solvent, we have done a large amount of experimental studies, sum up and both guarantee that the raw material solable matter extracts fully, the optimal proportion that helps energy savings again is: will be soaked in water after the offal polishing peeling, offal directly is soaked in water, and the solid-to-liquid ratio of employing is 1: 5～1: 15 (Kg: L).Add enzyme in this offal soak, the addition of enzyme is 0.05%～5% of an offal gross mass, and hydrolysis temperature is 20～50 ℃, and mixing speed is 5～60rmp, and enzymolysis time is 1～8 hour.
In the above-mentioned steps (1), offal is soaked in water, the solid-to-liquid ratio of gained offal soak is 1: 5～1: 15 (Kg: L), in this offal soak, add enzyme, the addition of enzyme is 0.05%～5% of an offal gross mass, temperature is 20～50 ℃ during enzymolysis processing, and mixing speed is 5～60rmp, and enzymolysis time is 1～8 hour.
In the above-mentioned steps (1), because offal contains a large amount of fibers and a spot of aroma component, therefore after offal being carried out the processing of step (1), its fibre composition is extract is used for follow-up sheets of fibres sheet base preparation, and the pectin that contains in the offal, sugar, starch and a small amount of aroma component then are used to follow-up coating fluid preparation; Though the fibre composition that offal contains is less, but offal contains a large amount of aroma components, after the processing through step (1), its aroma component is extract is used for follow-up coating fluid preparation, and the small amount of fibers composition that contains also can be used for the preparation of sheets of fibres sheet base; The present invention obtains by a large amount of experimental summaries, and the mass ratio of offal and offal is preferably 3: 1～and 1: 3, can obtain well to cause fragrant effect and sheet matrix amount.
The absorbent properties of reconstituted tobacoo sheet base are directly connected to the size of coating weight and the stability of product.After vanes extracted, broken especially easily, if the making beating degree is too high, blade was in small, broken bits, just might reduce the loose performance of sheet base to a great extent, reduced the absorbent properties of sheet base.The present invention is in above-mentioned steps (3), offal is handled separating obtained solid takes three grades to separate fine the processing, once separating fine beating degree is 10～25 ° of SR, and it is 13～26 ° of SR that secondary is separated fine beating degree, and the beating degree that enters finished product slurry tobacco stalk fibre at last is 14～35 ° of SR; Take secondary to separate fine the processing to the separating obtained solid of offal processing and get final product, once separating fine beating degree is 10～25 ° of SR, and it is 13～26 ° of SR that secondary is separated fine beating degree.Separate respectively to mix after fine the processing and carry out the operation of fiber brooming according to routine and obtain baccy fiber sheet base, preferred sheet base moisture is 25～35%; In order to improve the physical property of reconstituted tobacoo, common employing adds pin wood wood pulp fiber, and (it is long that this fibrid has fiber, the assorted less characteristics of gas) method realizes, the addition of wood pulp cellulose is generally 2～10% (dry matter percentage), the high more then physical property of addition is good more, but assorted gas can be big more, and the inventor finds that by practice the addition of wood pulp cellulose is controlled at 3～5% and can reaches than balance.
In the above-mentioned steps (3), the separating obtained liquid of combining step (2) before this liquid is concentrated, can add ethanol earlier, and the effect of ethanol is that precipitation merges the macromolecular substances in the gained liquid, and the addition of ethanol is 1～3 times of merging gained liquid volume.
In the above-mentioned steps (3), concentrating and can adopt existing direct heating atmospheric evaporation concentration method, indirect atmospheric evaporation concentration method, indirect vacuum concentration method that extract is concentrated, is 10～50% to get final product with liquid concentration to solid content.The present invention preferably adopts the vacuum concentration method to concentrate, and does not heat.Add reduced sugar and amino acid in concentrate, heating makes concentrate generation Maillard reaction; The Maillard reaction condition is: the addition of reduced sugar is 2.5%～10% of a concentrate quality, and reduced sugar is the wherein a kind of or any two or more mixture of wood sugar, ribose, arabinose, glucose, fructose, mannose, galactolipin; Amino acid whose addition is 2.5%～10% of a concentrate quality, and amino acid is the wherein a kind of or any two or more mixture of glycine, leucine, glutamic acid, proline, arginine, asparatate, phenylalanine; Regulating the total system pH of Maillard reaction is 6～8, and the Maillard reaction temperature is 85 ℃～130 ℃, mechanical agitation reaction 1～2 hour; The vitamin C (Vc) or the propane diols that can also add trace in the described Maillard reaction system, addition preferred 0.1%.
In the above-mentioned steps (4), the coating fluid temperature that is applied on the sheets of fibres sheet base is 50～60 ℃, and density is 1.200g/cm during 20 ℃ of coating fluids
3, viscosity is 0.01Pa.s during 20 ℃ of coating fluids.
According to actual needs, but repeating step (4) with the reconstituted tobacoo that obtains application step (3) gained coating fluid once more at every turn, preferably repeat 3 times, the reconstituted tobacoo that will obtain at last then section, the packing warehouse-in gets final product.
By enzymolysis the macromolecular compound in the tobacco is fully transformed and to be degraded to micromolecular compound, the fibre stuff of gained contains impurity components such as protein, pectin seldom after Separation of Solid and Liquid is handled, so the bulkiness that can improve thin slice sheet base effectively can reduce the assorted gas content of sheet base again, thereby provide good basis for the interior quality of improving reconstituted tobacoo; Gained liquid can be that Maillard reaction is created good sugared ammonia react basic condition for Maillard reaction provides more reduced sugar and amino acid, through the obtained coating fluid of Maillard reaction, has more fragrance of generation and gives reconstituted tobacoo strong fragrance.
Needs according to the practical application of reconstituted tobacoo in above-mentioned production of cigarettes, can adjust technical recipe of the present invention, for example utilize the Maillard reaction under the different condition to produce different fragrance components, prepare the thin slice of different aromas type, produce the cigarette of different flavor.Particularly, as adopting proline and fructose,, make and have puffed rice odor type thin slice in 150 ℃ of reactions 2 hours; Adopt asparatate and glucose,, produce roasting fragrant and sweet type thin slice in 105 ℃ of reactions 1.2 hours; Adopt asparatate, proline and fructose, glucose,, produce nut odor type thin slice in 105 ℃ of reactions 1 hour; Adopt phenylalanine and fructose, in 120 ℃ of reactions 1 hour, generation had the delicate fragrance type thin slice; Or the like.
The reconstituted tobacoo that above-mentioned preparation technology obtains can be used for production of cigarettes, this reconstituted tobacoo is added in the tobacco leaf formulation of cigarette, then can improve, adjust the physical property and the chemical composition of cigarette; According to a large amount of experimental summaries of the applicant, the addition of described reconstituted tobacoo can select to account for 2～50% of cigarette gross mass, can effectively reduce assorted gas content, the optimization mouthfeel of papermaking-method reconstituted tobaccos, enrichment cigarette perfume (or spice).

The specific embodiment
The present invention will be further described in detail below in conjunction with specific embodiment.
The selection experiment of embodiment 1 reconstituted tobacoo preparation condition
1, the selection of extraction conditions
The method of extracting tobacco waste can have multiple, as adds suitable chemicals method or hot water or cold water's direct method etc., is damaged less and realizes recycling as much as possible for the quality that guarantees tobacco active ingredient, and the selection of extracting method is very important.The present invention adopts extraction, is actually to adopt a kind of three stage countercurrent extraction processes.
Each part stalk carries out three times and extracts, and uses secondary raffinate, extract and water as extractant successively; Each portion extractant extracts three parts of stalks, is respectively the second extraction stalk, once extracts stalk and new the stalk.
Each part stalk and each step recovery rate of each portion extractant are studied, and be contrast with an extract.The recovery rate that same raw material extracts for three times reduces successively, the results are shown in Table shown in 1:
Table 1 recovery rate relatively
Average tendency from total recovery rate, there is the over dry material about 50% to be extracted out through the stalk after three extractions, and the extract solid content that extracted three stalks also reaches about 50%, so can think that the recovery rate that obstructs under these process conditions is about 50%, improve a lot compared with the recovery rate about 35% of existing common process.Each part stalk will extract through 3 times, extraction time increases, first order extraction time is 30 minutes, second level extraction time is 25 minutes, third level extraction time is 25 minutes, but because the improper stage when just bringing into operation is carried out in three grades of extractions simultaneously, each part stalk actual extracting is consuming time less, has shortened general 20% than existing common process.Mix reconstituted tobacoo cigarette smoking result from embodiment preparation hereinafter described, its suction quality and existing common process gained thin slice are slightly improving aspect assorted gas, the stimulation, can not influence the suction quality of papermaking-method reconstituted tobaccos product, but the inventive method can guarantee the high efficiency extraction of solable matter, also is the most effective energy saving and consumption reduction method simultaneously.
The selected different temperatures of present embodiment is investigated the optimum temperature of extraction.A large amount of experimental summaries obtain, the too low extraction that can not guarantee solable matter of temperature, and also temperature must prolong extraction time when low, could guarantee the yield of extraction; Temperature is too high, can not obviously improve the yield of extract, increases the loss of thermal energy consumption and aroma substance on the contrary.The result shows that under 50 ℃～80 ℃ temperature, extraction 30～60min can guarantee the extraction of solable matter, reduces energy resource consumption, avoids the loss of fragrance component again, keeps the quality of papermaking-method reconstituted tobaccos product.
2, the selection of method for concentration
Adopt direct heating atmospheric evaporation concentration method, vacuum concentration method that extract has been carried out concentration to the offal extract, listed the main chemical compositions of direct heating atmospheric evaporation concentration method and vacuum concentration method gained concentrate in the table 2.
Table 2 concentrates the chemical composition of the concentrate under the condition in difference
| Test item | Directly heat the normal pressure concentration method | The vacuum concentration method |
| Extracting liquid volume (ml) | ??5000 | ??5000 |
| Total reducing sugar % | ??5.10 | ??4.76 |
| Total nicotine % | ??0.767 | ??0.706 |
| Volatility total amount (%) | ??78 | ??80 |
| Concentration time (min) | ??120 | ??45 |
| Concentrate density (g/m 3) | ??1.20 | ??1.20 |
When the data from table 2 adopt the vacuum concentration method as can be seen, the concentration of total reducing sugar and total nicotine is low than other two kinds of methods in the concentrate, and when reaching normal concentration the needed time shorter, simultaneously, when adopting vacuum to concentrate, can suitably reduce thickening temperature, carry out low-temperature evaporation and have positive meaning for the fragrant quality that keeps tobacco active ingredient.
3, the selection of methods of beating
According to the strong and weak difference of pulping process, design four processes to the offal mechanism:
(1) light beating is discongested tobacco stalk fibre with light cutter and to be come, and beating time is longer.
(2) heavy beating is broken up tobacco stalk fibre with heavy cutter, and beating time is shorter.
(3) with heavy cutter tobacco stalk fibre is cut to a certain degree earlier, uses light cutter again instead tobacco stalk fibre is discongested out.
(4) with heavy cutter tobacco stalk fibre is cut to a certain degree earlier, uses light cutter again instead tobacco stalk fibre is discongested out, the beating degree raising of leaf.
(1), 15 ° of SR of leaf beating degree are adopted in (2), the experiment of (3) group, and the pulping process of stalk is the same with the 3rd group of test in (4) the group test, just the beating degree of leaf has been brought up to 25 ° of SR by 15 ° of SR.Each group is tested made slurry, (presses dry matter percentage, add 4～10% pin wood wood pulp cellulose) base in flakes of manufacturing paper with pulp, every physical property of detection lug base, and the relation of analysis pulping process and sheet base performance according to a certain percentage with plus fiber respectively.The experimental technique parameter the results are shown in Table 3, (detection method is a GB).
Table 3 stalk beating process parameter experimental result
The experimental result that concerns of sheet base tensile strength and making beating degree sees Table 4 and accompanying drawing 2 (among Fig. 2, four curves are respectively the sheet base tensile strength and making beating degree relation curve of offal numbering 1～4):
The relation of table 4 tensile strength and making beating degree
| The offal numbering | (1) group test | (2) group test | (3) group test | (4) group test |
| ??1# | ??0.424 | ??0.423 | ??0.489 | ??0.563 |
| ??2# | ??0.490 | ??0.487 | ??0.62 | ??0.71 |
| ??3# | ??0.557 | ??0.555 | ??0.665 | ??0.733 |
| ??4# | ??0.691 | ??0.653 | ??0.696 | ??0.800 |
By experiment as can be known, sheet base tensile strength not only has relation with beating degree, and is also very close with the pulping process relation.Beating degree improves, and tensile strength raises.Beating degree improves fiber size and reduces, and the interfibrous space that interweaves reduces, the also corresponding increase of intensity.But this reduces as cost with sheet base sponginess.The tensile strength of (1) group test and (2) group test is almost equal.This explanation is with the long-time defibrination of light cutter and with weighing cutter short time defibrination, the bond strength of pulping is suitable.(3) group test is with heavy cutter tobacco stalk fibre to be cut to a certain degree earlier, with light cutter fiber is discongested then and comes.The sheet base tensile strength maximum that the slurry of testing with this group is ferreted out, stock quality is more satisfactory.
The experimental result that concerns of air permeability and making beating degree sees Table 5 and accompanying drawing 3 (among Fig. 3, four curves are respectively the sheet base air permeability and making beating degree relation curve of offal numbering 1～4).
The relation of table 5 air permeability and making beating degree
| The offal numbering | (1) group test | (2) group test | (3) group test | (4) group test |
| ??1# | ??0.2835 | ??0.1652 | ??0.2278 | ??0.13075 |
| ??2# | ??0.166 | ??0.11546 | ??0.10218 | ??0.06726 |
| ??3# | ??0.1098 | ??0.09736 | ??0.07258 | ??0.05642 |
| ??4# | ??0.0876 | ??0.06262 | ??0.05544 | ??0.04676 |
The combustibility of air permeability and papermaking-method reconstituted tobaccos is in close relations, and air permeability large-scale combustion performance is better relatively.Show that from accompanying drawing 3 air permeability of (1) group test is best, the permeability of (4) group test is relatively poor, and the leaf slurry is under big beating degree, and that is beaten is in small, broken bits, has clogged the slit between the stalk pulp fibres, and permeability reduces.
Sheet base absorbent properties and making beating degree concern that experimental result sees Table 6, table 7 and accompanying drawing 4 be (among Fig. 4, article four, curve is respectively the sheet base water absorption rate and making beating degree relation curve of offal numbering 1～4), accompanying drawing 5 (among Fig. 5, four curves are respectively the sheet primary surface absorbent properties and making beating degree relation curve of offal numbering 1～4):
The absorbent properties of sheet base water absorption rate and two index expressions of water absorbent surface performance.What water absorption rate was represented is the climbing speed of water on paper slip, and unit is mm/second (mm/S).The water absorbent surface performance is the time that drop is absorbed fully by the sheet primary surface, and unit is second (S).Consider the absorbent properties of sheet base with these two index comprehensives to the coating feed liquid.
The relation of table 6 water absorption rate and making beating degree
| The offal numbering | (1) group test | (2) group test | (3) group test | (4) group test |
| ??1# | ??0.04665 | ??0.0337 | ??0.0417 | ??0.0367 |
| ??2# | ??0.03918 | ??0.0353 | ??0.0337 | ??0.0290 |
| ??3# | ??0.03868 | ??0.0348 | ??0.0297 | ??0.0297 |
| ??4# | ??0.034 | ??0.0292 | ??0.0275 | ??0.0287 |
Table 7 surface absorption can with the making beating degree relation
| The offal numbering | (1) group test | (2) group test | (3) group test | (4) |
| 1# water absorbent surface (S) | ??31.045 | ??29.898 | ??20.924 | ??32.988 |
| 2# water absorbent surface (S) | ??24.804 | ??32.354 | ??31.28 | ??37.032 |
