Abstract
The method discloses a method for improving tobacco leaf quality on an upper part of flue-cured tobacco by applying steam explosion technology, and relates to the technical field of tobacco processing. The method comprises the following steps of: performing steam explosion on the upper tobacco leaf of flue-cured tobacco, wherein the working medium for steam explosion is saturated steam, the steam explosion time is less than 0.01 second, the steam pressure is between 0.4 and 0.8 MPa, and the pressure preserving time is between 10 and 60 seconds; drying the upper tobacco leaf subjected to steam explosion, and reducing the moisture to 10-25 percent; and making the dried upper tobacco leaf enter a shredding and expanding process, and using the upper tobacco leaf in a cigarette formula. The method for improving the tobacco leaf quality effectively reduces the total plant alkaloid content in the tobacco leaf on the upper part of flue-cured tobacco, increases the content of reducing sugar, lightens the irritation and strength of the upper tobacco leaf, increases the aroma, effectively improves the combustibility of the tobacco leaf, makes the ratio of the upper tobacco leaf of the flue-cured tobacco to the cigarette formula increased from 10 percent to 15 percent, and effectively improves the utilization rate of the tobacco leaf on the upper part.
Description
Technical field
The present invention relates to a kind of applying steam explosion technology the flue-cured tobacco upper tobacco leaf is handled the method for improving its quality, belong to technical field of tobacco processing.
Background technology
The steam blasting technology is invented by Mason the earliest and is used for pulping process, is called the Masonite method.On this technology basis, people have carried out a large amount of research and improvement to steam explosion pulping subsequently, have produced Stake and Kokta method and some other important blasting technology, as Iotech and Siropulper.At present, the steam blasting technology has been successfully applied to fields such as sugaring, building materials, animal feed processing, leavening and lignocellulosic material preliminary treatment.For example stalk is through after the steam blasting, and its enzymatic hydrolyzation can reach 80%～90%, than having improved 60%～70% without the quick-fried stalk enzymatic hydrolyzation of vapour.In addition, Chen Hongzhang etc. discover that wheat straw waste is after vapour is quick-fried, and its hemicellulose and part lignin degradation are molecular substance, and make fiber loose, have porous (2009 years o. 11ths of intercalation army etc. " modern agriculture science and technology ").
Steam blasting can with infilter the inner compressed gas short time of plant tissue, sudden release finishes, because its action time is short, energy density is high and concentrated, and steam molecule can be penetrated between the big molecule such as cellulose and lignin, can on big molecular level material fully decomposed.A kind of method of raw material of steam blasting cellulose-containing is disclosed in Cofco Group Co., Ltd.'s patent application (200710121557.0), can make the continuous abundant aqueous vapor that absorbs under stable condition of raw material of fibre-bearing element, when pressure release, water vapour is gone out, the lignin sheath of embedding cellulose and hemicellulose in the raw material of abundant destruction fibre-bearing element, with the cellulose ratios that can contact with enzyme in the raw material that has increased the fibre-bearing element, its objective is that steam explosion products that raising is obtained by this method prepares the monose productive rate and the alcohol yied of monose and ethanol.
The flue-cured tobacco upper tobacco leaf is leaf narrower and identity is thicker, color is dark partially, oil content is lower, and tobacco tissue is closeer, and the nicotine content height, burning is slow, sucking property is low, and fillibility is general, big, the assorted gas of the dense strength of flavor is heavy, excitant is big; Usage ratio is lower in cigarette composition, generally can not be fully used as main material.
The present invention utilizes steam blasting technical finesse flue-cured tobacco upper tobacco leaf, high-pressure high-temperature environment condition by steam blasting promotes that material transforms in the upper tobacco leaf, by the total alkaloid content in the formation reduction cured tobacco leaf of the medium and small molecule acid of blasting process, alleviate the excitant and the strength of upper tobacco leaf, increase fragrance, and can effectively improve the flammability of tobacco leaf, improve the usage ratio of flue-cured tobacco upper leaf in prescription.
Summary of the invention
The objective of the invention is to adopt a kind of new tobacco leaf processing method, promptly utilize steam explosion that the flue-cured tobacco upper tobacco leaf is carried out explosion treatment, improve flue-cured tobacco upper tobacco leaf quality by the steam blasting technology.
The technical measures of realization the present invention's purpose are as follows:
A kind of method of improving tobacco leaf quality on upper part of flue-cured tobacco by applying steam explosion technology may further comprise the steps:
(1) the flue-cured tobacco upper tobacco leaf is carried out steam blasting, the steam blasting working media is a saturated vapor;
(2) upper tobacco leaf after quick-fried carries out drying to vapour, and its moisture content is reduced to 10%～25%;
(3) after being entered the chopping expansion process, dried upper tobacco leaf is used for cigarette composition.
The above-mentioned method of improving flue-cured tobacco upper tobacco leaf quality is used steam blasting that the tobacco leaf upper smoke is continued to twist and is handled, by the high temperature high pressure process process promote material in the tobacco leaf chemical change, improve sucking quality.
The above-mentioned method of improving flue-cured tobacco upper tobacco leaf quality, steam blasting use saturated vapor as working media, and its operating pressure is between 0.4MPa～0.8MPa, and the pressure retention time is between 10～60 seconds, and the steam blasting time was less than 0.01 second.
The reduced sugar of flue-cured tobacco upper tobacco leaf and total alkaloid are the main chemical compositions that influences the smoking property of cigarette mouthfeel, reduced sugar and total alkaloid situation of change such as following table before and after the test specimen steam blasting:
Reduced sugar and total alkaloid situation of change table before and after the upper smoke steam blasting
| Index | Content of reducing sugar (%) | Total alkaloid content (%) |
| Tobacco sample before the explosion | 16.77 | 2.31 |
| Tobacco sample after the explosion | 24.39 | 1.78 |
| Rate of change (%) | +45.44 | -22.94 |
Simultaneously, steam blasting upper smoke and unprocessed upper smoke are carried out expert's comparison of smokeing panel test according to the cigarette of existing prescription processing, the result shows, sample fragrance after steam blasting is handled is sent out thoroughly, excitant and strength obviously reduce, and flammability is good, and sucking quality is whole to be promoted.
Simultaneously, a certain high-grade cigarette experimental production that applies the present invention to shows that the usage ratio of original prescription upper tobacco leaf is 10%, the new prescription that the quick-fried processing of the vapour upper back tobacco leaf of application 15% is formed, and aesthetic quality and original formulation are consistent.
Compared with prior art, the invention has the beneficial effects as follows:
(1) proposes the processing method that the steam blasting technology is carried out upgrading to the flue-cured tobacco upper tobacco leaf, can shorten the tobacco mellowing time;
(2) by the invention process, effectively reduce the total alkaloid content in the flue-cured tobacco upper tobacco leaf, alleviated the excitant and the strength of upper tobacco leaf, increased fragrance, and effectively improved the flammability of tobacco leaf;
(3) the present invention has increased the usage ratio of flue-cured tobacco upper tobacco leaf in cigarette composition and has been increased to 15% from 10%, has effectively improved the utilization rate of upper tobacco leaf.
