Description
Technical field
The invention belongs to technical field of tobacco processing, relate to the improvement of cabo quality.Specifically, relate to a kind ofly utilize Threshing Re-dry Product Line to press stalk, storage stalk and carry out enzymolysis, thereby realize improving the preprocess method of cabo quality.
Background technology
Offal is the main accessory substance of cigarette industry enterprise, accounts for about 25%～30% of tobacco leaf gross weight.Present stage, tobacco business was generally with adding to behind the cabo expansion in the cigarette composition, in addition, also had offal is prepared into granule peduncle and thin slice is used.But because the main component of offal is a cell wall substance; The cracking meeting of these materials produces more low-grade aldehydes, catechol etc., and the application of its elaboration products in cigarette will influence quality of cigarette, and generally the consumption of its elaboration products is all less; Therefore; How to promote offal elaboration products quality, effectively promote the use amount of offal elaboration products, the most basic research direction is exactly the quality that promotes offal.
The researcher is through having done more research to the offal preliminary treatment with the purpose that promotes cabo quality.Peng Cheng etc. have studied the influence of Co-γ irradiation to the offal main chemical compositions, find that this kind radiation mode can increase the content of polyphenol in the offal; People such as Zhou Yuanqing utilize lignin degradation microorganism and lignin-degrading enzymes to handle offal, can obviously remove xylon gas, the excitant of offal, and its filling value has increased by 35.2～42.8% simultaneously; Lin Xiang etc. utilize complex enzyme to carry out improving the research of cabo quality, and in the offal after finding to handle, total sugar content is increased to 22.8%, and the total amount of main fragrance component has promoted 27%, has improved the content and the ratio of aroma substance; Xiao Ruiyun has studied the processing of different composite enzyme to offal, and the result shows the harmony that complex enzyme is handled can increase offal; People such as Tao Hong have carried out the alkali treatment research of offal, adopt NaOH and H
2O
2The Combined Treatment offal can make cell wall substance, lignin, total nitrogen and the total reducing sugar of offal descend 12.71,2.14,1.24 and 10.28% respectively, and the filling value has increased 10.34%; People such as Mao Yao have developed the imitative enzyme of Fe-CA on the basis of biology enzyme effect, said preparation can efficiently remove the lignin in the offal; People such as Li Jun have adopted different solvents to handle offal, after process stem, find solvent processing after, the filling value of stem has increased by 11.4%, its chemical composition and aroma component content have bigger variation simultaneously, the stem interior quality is had preferably improve; People such as Zhu Junzhao have carried out improving research to tobacco stalk pretreatment process, have adopted the pretreating process that soaks stalk and the combination of microwave profit stalk, find that this treatment process can save the production time, make the filling value of stem be greatly improved.
In addition, the pretreated related patent U.S. Patent No. of offal is also more.Introduced employing microwave solids media particle in the patent 03117228.8 and done media,, can reduce the xylon gas of offal, improved quality with the offal Hybrid Heating; Patent 201010239039.0 discloses and has utilized removal of impurities, steamed the pretreating process that obstructs, cuts stalk; Patent 20101025022.4 has been introduced the tobacco stalk pretreatment process that soaks stalk, heating using microwave, buffer feeding, metering, pressure stalk, chopping, has shortened the production cycle, has improved quality; Patent 200710054816.2 discloses the pretreating process that washing, storage, medium soak, expand, feed in raw material, and stem color that obtains and shape and pipe tobacco are approaching, mix different substances together the uniformity height, and interior quality is good; Patent 201010039155.8 discloses a kind of preprocess method of tobacco stalk raw material, adopts ammonium salt and quick lime that offal is handled, and pile 20～40 days can improve offal physics and chemistry structure, and has improved the interior quality of offal; Patent 201010252392.2 discloses the technology that a kind of applying steam explosion and enzyme treatment technique improve tobacco stalk quality, has solved the long processing period that exists in the existing stem treatment process and the problem of moisture regain weak effect, has optimized existing stem treatment process; Patent 200510104443.6 has been introduced a kind of complex enzyme formulation and has been used for the technology that offal is produced, and can significantly improve the assorted gas and the excitant of offal.In addition, United States Patent (USP) 5564444 has been introduced a kind of method of growing stalk and short stalk mixing application; United States Patent (USP) 4388933 has also been introduced the method that adopts weak base and hydrogen peroxide to reduce the content of lignin in the offal.United States Patent (USP) 5873372A has also introduced the method for steam blasting, can improve the interior quality of offal.
In general; Although present stage handles offal more research has been arranged, and obtained different effects, because the particular tissues structure of offal; The periphery is wrapped up by one deck wax material; General macromolecular substances is difficult to directly penetrate into pair cell wall material effect in the institutional framework, must destroy the institutional framework of offal through the mode of chemistry or physics after, just help post-processed.There is the researcher to adopt chemical mode such as NaOH and H
2O
2Mode handle, but chemical substance is easy to generate pollution, causes subsequent treatment cost to increase; Also the someone adopts the physics mode effect, and like steam blasting, but institute's energy requirement is higher; And the adding of other various biologic products owing to be macromolecular substances, is difficult to directly touch the offal interior tissue, and functioning efficiency is not high, therefore at first need destroy the offal institutional framework.
Summary of the invention
The objective of the invention is to the deficiency to prior art, a kind of existing equipment, easy and simple to handle, preprocess method that can effectively improve cabo quality of making full use of is provided.
The object of the invention is achieved through following technical scheme.
* except as otherwise noted, the percentage that is adopted among the present invention is mass percent.
A kind of preprocess method that improves cabo quality may further comprise the steps:
(1) the stalk leaf separates: obtain offal after tobacco leaf economy-combat leaf, the screening, control offal moisture content is 16～19%;
(2) press stalk, enzyme preparation to add and the storage stalk: to place tobacco stem flattener to be pressed into the stalk sheet offal; Add enzyme preparation according to the ratio of stalk tablet quality 3～5% again, the stalk sheet after the interpolation enzyme preparation places the sealing warehouse of 40～50 ℃ of temperature, humidity 50%～60% to store 24h; Described enzyme preparation is made up of pectase, laccase and cellulase, and its mass ratio is 5: 2: 3;
(3) roasting stalk: the stalk sheet after the storage is baked 140～150 ℃ of stalk temperature with the roasting stalk of cylinder, and control stalk sheet moisture content is 11～13%, and boxing for later use is accomplished the preliminary treatment of obstructing sheet.
The thickness of said stalk sheet is that 1～2mm, moisture content are 16～19%.
Adopt the mode of air compression to add enzyme preparation.
Compared with prior art, the present invention has the following advantages:
