Description
Technical Field
The invention belongs to the technical field of tobacco preparation, and particularly relates to recombinant tobacco and a preparation method of the recombinant tobacco.
Background
Through the development of over ten years, the reconstituted tobacco is slowly developed from the rapid quality improvement to the present stage, and the quality of the reconstituted tobacco is in the bottleneck period at present, which is specifically shown in the following steps: the hot water soluble matter of the nationwide reconstituted tobacco is 34-40%, the hot water soluble matter content of the natural tobacco is more than 55%, the hot water soluble matter reflects the coating rate and directly influences the sensory quality of the reconstituted tobacco, the hot water soluble matter contains a large amount of aroma components, and the total amount of the aroma components of the reconstituted tobacco shreds is only about 30% of the total amount of the aroma components of the natural tobacco. The difference between the sensory quality of the reconstituted tobacco and the natural tobacco is the most direct, and the main reason is the difference between the sensory quality of the reconstituted tobacco and the natural tobacco in hot water soluble substances; however, the sheet base manufactured and molded by the traditional paper-making method has the defects of poor absorptivity and permeability due to low bulk and compact surface of the sheet base due to the limitation of the traditional paper-making method reconstituted tobacco production process, the coating liquid is difficult to permeate into the sheet base, when the coating rate exceeds 40%, the coating liquid remained on the surface of the sheet base forms a crystalline coating layer, and after extrusion, the adhesion between the sheet and the sheet is formed, and finally the finished product is hardened and agglomerated, thereby causing great influence on the production and use of subsequent cigarettes. In addition, the extraction and pulping processes of the diversification and the nonhomogeneity of the source of the paper-making reconstituted tobacco raw materials face the problems of insufficient extraction and nonuniform pulping, so that the base sheets manufactured by paper making show the basic characteristics of rough surface, unstable transverse width quantification, poor uniformity, large physical index fluctuation, poor base sheet absorption performance and difficult coating liquid loading, and the prepared finished products also show the basic characteristics of rough surface, nonuniform coating, large processing resistance index fluctuation, large quality fluctuation and the like. Therefore, how to break through and improve the low spreading rate of the reconstituted tobacco at present and improve the stability and uniformity of finished products becomes a key means for greatly improving the quality of the reconstituted tobacco.
As can be seen by looking up the current literature data, the technical research on how to improve the spreading rate of the reconstituted tobacco leaves has been reported. For example, the invention patent (application number: CN201610572948.3) adopts a mode of separately pulping softwood fibers and hardwood fibers, thereby avoiding the problems of increased mixed pulping fine fibers and lower substrate bulk, increasing the coating rate of reconstituted tobacco, and the process of the method can bring influence on the physical properties of the reconstituted tobacco, is not beneficial to production control and has unobvious application effect; the invention patent (application number: CN201110152311.6) adopts the method that the paper base after the slurry forming is punched and then is coated with the coating liquid, thereby obviously improving the absorption performance of the paper base to the coating liquid and finally improving the coating rate; the invention patent (application number: CN201910967732.0) utilizes the mechanical effect, cavitation and thermal effect of ultrasonic wave to improve the adsorption and penetration performance of macromolecular substances in the coating liquid on the surface of a substrate, so that chemical components in the coating liquid can rapidly enter the substrate, the condition that the coating liquid is only accumulated on the surface of the substrate and cannot penetrate into the substrate is avoided, and the coating rate can be effectively improved.
Disclosure of Invention
The invention aims to provide the reconstituted tobacco capable of replacing natural tobacco raw materials, the product has the same or similar quality of the natural tobacco raw materials, and the problems of low raw material extraction yield, poor film base absorption performance, low coating rate of the finished reconstituted tobacco products, low hot water soluble matter, product agglomeration after the coating rate is improved and the like in the production process of the reconstituted tobacco by the traditional paper-making method are solved; the product has stronger plasticity of style characteristics in the preparation process, can highly restore the inherent quality characteristics of the tobacco raw materials, retains the advantages of the smoke, aroma and style characteristics of the tobacco raw materials, and can improve the negative influence on sensory quality caused by the defects of the tobacco raw materials. The invention provides a recombinant tobacco and a preparation method of the recombinant tobacco.
In order to achieve the above objects and to overcome the above deficiencies of the prior art, the present invention is implemented as follows.
The recombined tobacco comprises the following raw materials in parts by weight:
70-92 parts of superfine tobacco powder
8-30 parts of cellulose fiber
0.2-1.0 part of assistant
1-5.0 parts of humectant
0-5.0 parts of perfume raw material
Wherein the auxiliary agent is one or more of tamarind polysaccharide gum, cationic starch, guar gum and chitosan;
the superfine tobacco powder is characterized in that: the median particle diameter D50 is 139.20 um-31.34 um, the content of particle diameter less than 20um is 16.64% -33.88%.
Further, the superfine tobacco powder is one or a combination of a plurality of crushed tobacco raw materials, tobacco fragments, tobacco stems, tobacco powder and the like.
Further, the cellulose fiber is one or more of wood pulp (softwood pulp, hardwood pulp), hemp pulp (flax pulp or hemp pulp), cotton pulp, bamboo pulp, straw pulp and fluff pulp.
Further, the humectant is one or more of glycerol, propylene glycol, ethylene glycol, sorbitol, butylene glycol and honey.
Further, the fragrant raw material is one or a combination of more of alcohol extract, water extract, essential oil and absolute oil of tobacco and fragrant plants.
Further, the preparation method of the recombinant tobacco comprises the following steps:
s1, crushing tobacco raw materials by adopting crushing equipment to prepare superfine tobacco powder;
s2, mixing the superfine tobacco powder prepared in the step S1 with water for extraction, and filtering to obtain an extracting solution and filter residues after the extraction is finished;
s3, concentrating the extracting solution prepared in the step S2 to prepare a concentrated solution, and adding a fragrant raw material into the concentrated solution to prepare a coating liquid for later use;
s4, mixing cellulose fibers with water, pulping according to a pulping process, and preparing cellulose fiber slurry for later use after pulping is completed;
s5, mixing the filter residue obtained in the step S2 with the cellulose fiber slurry obtained in the step S4, adding an auxiliary agent, and fully and uniformly mixing to obtain a mixed slurry;
s6, manufacturing the mixed slurry prepared in the step S5 according to a paper-making reconstituted tobacco sheet base manufacturing and forming process to prepare a sheet base;
s7, coating the coating liquid prepared in the step S3 and the film base prepared in the step S6 according to a paper-making reconstituted tobacco coating process to prepare a coating sample;
and S8, drying and cutting the coating sample prepared in the step S7 to obtain the recombined tobacco product.
Further, the ultra-fine tobacco powder in the step S1 is characterized by: the median particle size (D50) is 139.20 um-31.34 um, the content of particle size smaller than 20um is 16.64% -33.88%. Further, in the step S2, the mixing weight ratio of the superfine tobacco powder to the water is 1: 4.6-8, the extraction temperature is 50-80 ℃, and the extraction time is 15-70 min.
Further, in the step S4, in the pulping process, the slurry has a Shore beating degree of 20-50 SR degrees.
Further, the oven dry basis weight of the sheet base prepared by paper making in the step S6 is 40g/m2～60g/m2；
The oven dry basis weight of the coating sample prepared in the step S7 is 72.5g/m2～150g/m2. The working principle of the invention is as follows:
crushing the raw materials by using crushing equipment to prepare superfine powder with median diameter D50 of 139.20 um-31.34 um and particle size content of less than 20um of 16.64% -33.88%, adding water, mixing, and separating to obtain an extracting solution and filter residue; adding filter residue extracted from raw materials and an auxiliary agent into the slurry prepared by the cellulose fiber pulping to prepare mixed slurry, and then manufacturing and forming the mixed slurry to obtain the film base.
Because the raw material is ultra-fine powder, if the average diameter of the plant cells is 20um (the grain diameter of most plant cells is between 10um and 30 um), when the grain diameter content of 20um is between 16.64 percent and 33.88 percent, the tobacco cells accounting for 16.64 percent to 33.88 percent have been broken, the degree of broken cell walls is different, and the prepared film base has different quantitative, thickness, bulk, air permeability, tensile strength, tensile rate, moisture absorption rate and other indexes which are important factors influencing the coating rate, smoothness, uniformity, physicochemical indexes, sensory quality and the like of finished products.
Tamarind gum, on the other hand, is a water-soluble xyloglucan, a water-soluble polymeric polysaccharide with glucose as the backbone and galactose and xylose as side chains. Xyloglucan is a polysaccharide present in the cell walls of higher plants, in particular the wall (main wall) fraction in which many plant cells grow. In addition, xyloglucan has a network-forming crosslinked microfibril, and therefore, the polysaccharide molecule has a strong hydrophilicity and is capable of binding many water molecules (i.e., hydration) and generating a certain viscosity, and the viscosity of the polysaccharide solution is not so high, but it is characterized by having a thickening effect in the presence of a sugar and inducing gelation.
