Abstract
The invention relates to a method for adjusting and controlling the content of nicotine in a tobacco extract. The invention aims at solving the problems of complicated technique, relatively high cost, easily damaged original aromatic components in tobacco and chemical agent residue in the extract in adjusting and controlling the content of the nicotine in the tobacco extract during the production of reconstituted tobacco leaves in the existing paper-process. The technical keys are as follows: the method is characterized in that a tobacco raw material extract used in the production of the reconstituted tobacco leaves in the paper-process is selected, a solvent is used for diluting the extract to a set concentration, the diluent obtained is put into an ultrafiltration membrane circulating device for circulation and filtration to obtain a trapped liquid which is low in nicotine content and trapped by a ultrafiltration membrane and a dialyzate which is high in nicotine content and permeates the ultrafiltration membrane, wherein, the trapped liquid is used as a material which is coated on and refilled into a substrate during the production of the reconstituted tobacco leaves in the paper-process and the dialyzate is used as a material with special usage.
Description
Technical field
The present invention relates to change the technology of nicotine content in the tobacco, particularly a kind of method of utilizing nicotine content in the milipore filter isolation technics regulation and control tobacco extract.Be applicable to the production of papermaking-method reconstituted tobaccos.
Background technology
Generally contain 1～3% nicotine in the natural tobacco leaf.Nicotine is commonly called as nicotine, an amount of take in can excited spirit, eliminate tired, increase thinking ability, increase work efficiency, also have certain anesthetic effect, this is the why places of smoking of many smokers.But nicotine is toxic, and excessive absorption can damage health, as bringing out nervous system disorders such as chronic pharyngitis, breathing problem, angiocardiopathy, some disease of digestive tract and headache, insomnia, inpairment of vision.Under the reality that can't give up smoking fully at present, the nicotine content that regulation and control reduce in the common cigarette has become the target that the tobacco curing industry is pursued.In addition, in order to adapt to different smokers' different requirements, the tobacco curing industry is generally produced the tobacco product of different nicotine contents by the papermaking-method reconstituted tobaccos technology, so also often need the nicotine content in extraction of regulation and control tobacco or the extract in papermaking-method reconstituted tobaccos is produced.
The prior art of nicotine content in the present existing change cigarette, a kind of medicament and application that reduces nicotine just like No. the 02159036.2nd, Chinese patent, be that liquid preparation with a kind of degrading nicotine is sprayed directly on the pipe tobacco or with the medicament powder and directly mixes in pipe tobacco, but this method can change the taste of conventional cigarette, also can cause the suction of non-cigarette material, not easy for consumers to accept.The Processes and apparatus of the producing tobacco flake in method similar to papermaking of Chinese patent No. No. 93120477.1 and for example, be after tobacco material (tobacco leaf, offal, fragment and offal) is extracted or extracts by solution, through solid-liquid separation process, substrate is used to manufacture paper with pulp with solid (fiber, half fiber, lignin etc.), to extract or extract partly through concentrating, the coating of modulation back is backfilling on the substrate, makes the papermaking-method reconstituted tobaccos product after operation such as toast, cut.During papermaking-method reconstituted tobaccos is produced, when needing the regulation and control nicotine content, generally can take out partial nicotinic by processes such as phase-splitting precipitation, chemisorbed, but complex process, cost are higher, the original aroma component of tobacco is damaged easily, also exist chemical agent extract or extract in residual problem.
Summary of the invention
In order to overcome in the existing papermaking-method reconstituted tobaccos production, the regulation and control tobacco extract or extract in higher, the original aroma component of tobacco of the existing complex process of nicotine content, cost be damaged easily, exist chemical agent extract or extract in residual defective, the purpose of this invention is to provide that a kind of improved regulation and control tobacco is extracted or extract in the method for nicotine content, can overcome the defective of prior art.
The present invention solves the technical scheme that its technical problem takes: a kind of regulate and control that tobacco is extracted or extract in the method for nicotine content, it is characterized in that: the tobacco material of getting in the papermaking-method reconstituted tobaccos production extracts or extract, with solvent dilution to concentration is 1～50%, dilution put in milipore filter (MWCO) EGR that a specification is molecular weight cut off 2000～5000 dalton (Dalton) carry out circulating filtration, obtain the trapped fluid of the low nicotine content held back by milipore filter and see through the dislysate of the high-nicotine content of milipore filter, trapped fluid is backfilling into usefulness on the substrate as coating in the papermaking-method reconstituted tobaccos production, and dislysate is used as specific use.
The so-called specific use of technique scheme be meant as the nicotine content of trapped fluid adjust compatibility agent, with doing have the substrate of specific (special) requirements to be coated with backfill liquid or to be used to make pure nicotine etc. to nicotine content.
The milipore filter EGR of technique scheme can be made of batch can, liquid pump and membrane module, be provided with milipore filter (MWCO) in the membrane module, the infusion port of batch can is connected with the inlet of liquid pump by pipeline, the liquid outlet of liquid pump is connected with membrane module by pipeline, the liquid outlet of holding back of membrane module is connected with the inlet of batch can by pipeline, the dialysis liquid outlet of membrane module is used to export dislysate, also is provided with charging aperture and valve control liquid outlet on the batch can, and the valve control liquid outlet of batch can is used to export trapped fluid.
The solvent of technique scheme is that water or concentration are lower than 30% alcoholic solution.
The so-called height of the trapped fluid nicotine content of technique scheme and dislysate nicotine content is that both compare.
Beneficial effect of the present invention: because by a milipore filter EGR, just tobacco material extraction or extract can be isolated low nicotine content part and high-nicotine content part, use its low nicotine content partly to be coated with and be backfilling on the substrate of papermaking-method reconstituted tobaccos production, just can reach the nicotine content of direct reduction papermaking-method reconstituted tobaccos; Simultaneously available high-nicotine content is partly adjusted compatibility low nicotine content part, and the nicotine content that reaches papermaking-method reconstituted tobaccos is controlled, is convenient to produce the tobacco product of different nicotine contents; The method technology of nicotine content is simple in extraction of this regulation and control tobacco or the extract, cost is low, can not destroy the original aroma component of tobacco, do not have chemical agent residual problem in extraction or extract, is a kind of desirable process that is suitable for applying.The dislysate of high-nicotine content part also can be used for producing needs the extra high special cigarettes product of nicotine content, be used to make pure nicotine or other needs the field of nicotine, and the range of application of tobacco material extraction or extract is enlarged.
For a more detailed description below in conjunction with drawings and Examples to the present invention.
