Abstract
The invention discloses a method for improving the quality of the tobacco shreds of cigarettes. The method comprises the following steps of: dissolving malate into water or the mixed solution of ethanol and the water according to 0.1 to 25 percent and regulating the acidity of the mixture to 6.0 to 6.8AV by adopting malic acid; alcoholizing tobacco leaves according to the addition proportion of 0.01 to 5 percent for 180 to 360 days; and preparing the alcoholized tobacco leaves into tobacco shreds, baking at the temperature of 120 to 140 DEG C for 4 to 6 minutes, storing the shreds for 3 to 5 hours and controlling the water content of the tobacco shreds to be 10 to 16 percent so as to obtain the required tobacco shreds of cigarettes. The system test data of different leaf combination formulae show that the invention can effectively improve the quality of the tobacco shreds and further enhances the smoking quality of the cigarettes.
Description
Technical field
The present invention relates to the processing method of pipe tobacco and tobacco leaf, more particularly, the present invention relates to a kind of method of improving quality of tobacco shreds of cigarettes.
Background technology
The control of the tar in the cigarette mainstream flue gas, nicotine and other harmful components is great research topics that whole world tobacco business is faced.Along with " (Framework Convention on Tobacco Control " in 2005 formally effective in China, it is increasing that China's tobacco business faces the pressure that the criterion of " tobacco component control and disclosure " brings.
At present, the method that reduces harmful components in the cigarette mainstream flue gas mainly adopts filter tip aeration technology and composite tip stick technology.These technology are with strong points, and use is extensive and effect is obvious, and still, the problem that also can bring simultaneously is the loss of tobacco flavor material, and the flue gas abundance is decreased.
Malic acid is a kind of natural organic acids, has the important physical function, has antifatigue, protects liver, kidney, heart effect, can it be developed as health drink.Be widely used in industries such as food, medicine, chemical industry, building materials at present, become the acid condiment that after citric acid, lactic acid consumption ranked third the position.At present, consume in U.S.'s year more than 1,500 ten thousand pounds, wherein 90% is used for Food & Drink processing.And Japanese scholar successfully is applied to malate to subtract in sugar, the salt-decreasing food in recent years, simultaneously can be as the salt substitute (Liu Jianjun, Food Additives Used in China, 2003) of nephritis patient.Usually, the method for extraction malic acid is the milk of lime precipitation method from natural plants.And the method for oxidation fumaric acid is mainly adopted in chemical synthesis, but the product that obtains is DL type mixture (Wang Boyan, fermentation organic acid production and an application manual).Also can adopt microbe fermentation method through a step or multistep fermentation gained.
In 92 kinds of elements that nature exists, known tobacco growing is grown essential unit and is have 17 kinds.Wherein the more unit of content have 9 kinds of C, H, O, N, S, P, K, Ca, Mg etc. in the tobacco, and trace element has 8 kinds of Fe, B, Cu, Zn, Mn, Cl, Mo, Ni etc.Indispensable element is grown with the formation ten minutes of quality important to tobacco growing, it not only influences growing of tobacco and output, and can change the correlation of attributes indexs such as flammability, color and luster, elasticity, suction flavor, filling power of tobacco.The content of trace element in tobacco leaf generally maintains tens ng/g between the hundreds of μ g/g.But its trace element of the tobacco leaf of different regions growth is formed and is varied, and causes using the fluctuation of the cigarette quality that these raw materials produce to a certain extent.Big quantity research shows: trace element as: lithium, beryllium, calcium, copper, zinc, manganese, molybdenum, nickel etc. have more significantly influence to cigarette odor-absorbing.Therefore, how improving the quality of cigarette shreds targetedly, is the technical barrier that this area waits to solve.
Summary of the invention
The objective of the invention is weak point, especially, a kind of method of improving quality of tobacco shreds of cigarettes is provided to suction quality problems such as the flue gas drying sense that is faced in the smoking property of cigarette process, burr senses to prior art.Simultaneously, said method also has the effect that reduces harmful components such as tar, nicotine, ammonia in the cigarette mainstream flue gas.
The object of the invention is achieved through following technical proposals.
* except as otherwise noted, the percentage that is adopted among the present invention is mass percent.
A. the invention provides a kind of method of improving quality of tobacco shreds of cigarettes, described method adopts following steps:
1. malate 0.1%～25% is dissolved in the mixed solution of water or second alcohol and water, and the employing malic acid is 6.0～6.8AV with its acidity adjustment;
With the described solution of step 1 by 0.01%～5% adding proportion, tobacco leaf is refined processing, the alcoholization time is 180～360 days;
3. the tobacco leaf after will refining is processed pipe tobacco, and baking temperature is 120 ℃～140 ℃, and stoving time is 4～6 minutes, and the storage silk time is 3～5 hours, and the pipe tobacco moisture content is controlled to be 10%～16%, is required cigarette shreds.
Wherein, the described alcoholization processing of step 2 is to tobacco leaf surface with described spray solution; Described tobacco leaf comprises C4F, B2R, B3F, B3F, B2L, B2V, B3R, B4F, C4L, B3L, B3V, B1K, B2K, B3K, GY1, GY2 or B4L; The described cigarette of step 3 is fire-cured tobacco type or blended type cigarette.
B. the malate that the present invention adopted, chemical name are the 2-malate, and chemical structural formula is:
Wherein, the configuration of its 2 carbon atoms can be the R type, the S type, and M can independently choose wantonly from following element or functional group, or the combination of following element or functional group, or the combination of its stereoisomer, enantiomter, diastereoisomer, racemic modification.M is selected from following element:
Hydrogen (H), ammonium (NH4), sodium (Na), potassium (K), lithium (Li), beryllium (Be), magnesium (Mg), aluminium (Al), calcium (Ca), iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), molybdenum (Mo), nickel (Ni).
Compared with prior art, the present invention has following beneficial effect:
System test data of different leaf combination formulae shows that described method can be improved the quality of cigarette shreds effectively, reduces the not mature sense that tobacco leaf brought, and the burr sense increases throat's moisture feeling.Make in the cigarette mainstream flue gas nicotine burst size reduce 5%～10% than blank sample, NH
3Burst size reduces 10%～13% than blank sample, and releasing content of coke tar reduces 5%～8% than blank sample, and flue gas moisture increases by 1%～9% than blank sample.Simultaneously, the moderate-element and the trace element that can replenish in the tobacco leaf to be lacked improve the soften and the fine and smooth degree of flue gas, have further improved the suction quality of cigarette.
The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
