Description
Technical field
The invention belongs to technical field of cigarettes, the preparation method of a kind of enzymolysis specifically-carboxymethylated starch matter humectant for smoke and application thereof, this humectant environmental protection, with low cost, and there is the effect simultaneously improving the humectation of tobacco physics and sense organ humectation.
Background technology
Humectant is a kind of indispensable auxiliary agent in production of cigarettes process, in production of cigarettes, transport, storage, sale and sucking process, humectant can keep moisture content in leaves effectively, increase the flexibility of tobacco leaf, improve the degrading resistance property of tobacco, reduce tobacco leaf making in the course of processing broken, reduce the tobacco leaf consumption of cigarette.Meanwhile, humectant also has reduction flue gas stimulates, improves effect that is jealous and mouthfeel.
The humectant that current domestic tobacco productive corporation uses mainly contains the polyalcohols such as propylene glycol, glycerine and sorbyl alcohol.Propylene glycol and glycerine are mainly the petroleum chemicals of raw material with oil and gas, expensive, though sorbyl alcohol low price humectation effect and aesthetic quality slightly poor.Because propylene glycol has certain volatility, therefore there is quite a few propylene glycol to enter flue gas during cigarette burning and form tar, burnt unfavorable to falling.Study pyrolysis product mainly acetaldehyde and the acetone also showing propylene glycol in addition, pyrolysis product mainly acetaldehyde and the propenal of glycerine, the use of these traditional humectants to cause in flue gas the harmful substance contents such as acetaldehyde to raise.In addition, propylene glycol, glycerine and sorbyl alcohol consumption also can bring pungent odour to flue gas slightly greatly, unfavorable to cigarette taste.
Therefore, the important directions that development of new is efficient, green safety, natural baccy humectant with low cost become cigaret additive research field.Chinese patent CN200910273418.9 discloses a kind of phoenix caudal lobe volatile oil cigarette sense organ humectant extracted from phoenix caudal lobe.Chinese patent CN200910061990.9 discloses a kind of konjac humectant and the application in cigarette thereof, and konjac humectant is prepared by extraction using alcohol.Chinese patent CN200910273359.5 discloses a kind of mango alcohol extract cigarette sense organ humectant.Chinese patent CN201010155428.5 discloses a kind of preparation of compound polyose humectant and the application in cigarette thereof, and its preparation flow mainly Chinese medicine extract concentrates obtain polysaccharide humectant through enzymolysis, macroporous resin column adsorption filtration, Rotary Evaporators.But it is complicated that these natural plant extracts humectant ubiquities above-mentioned preparation flow, the problems such as cost is higher, raw material sources are few, therefore not yet obtain popularity application.
Summary of the invention
For the deficiencies in the prior art, the present invention take starch as raw material, successively by enzymolysis modified and carboxymethyl-modification, prepares a kind of new and effective, environmental protection, starchiness humectant for smoke with low cost.
Invention mechanism of the present invention is: from molecular structure, and containing three hydroxyls in each glucose unit of composition starch polymer, a large amount of hydroxyls imparts the good water-retentivity of starch.The enzymolysis modified molecular weight reducing starch in the present invention, enhances water-soluble, and is conducive to the content improving solids in humectant, thus strengthens its water suction and water retention capacity; The carboxymethyl (sodium) with more strongly hydrophilic is incorporated in starch molecule by the carboxymethyl-modification in the present invention, greatly improves its water suction and water retention capacity.
The object of the invention is to be achieved through the following technical solutions:
The preparation method of a kind of enzymolysis-carboxymethylated starch matter humectant for smoke, be prepared from through enzymolysis, carboxymethyl-modification by following raw material, add in every 350g starch: α-amylase 5-120mg, ethanol/water solution 400-1200g, sodium hydroxide 30-120g, sodium chloroacetate 50-230g, concrete grammar is as follows:
(1) 350g starch is added to the water, the starch milk of furnishing 30%-40%, about regulation system pH=6, then 5-120mg α-amylase is added, after 70 DEG C-105 DEG C reaction 10min-200min, carry out going out enzyme, and carry out successively cooling, dewater, dry, pulverize and screening, obtain enzymatic starch;
(2) enzymatic starch is joined in ethanol/water solution, be made into the starch milk of 30%-44%, then 30-120g sodium hydroxide and 50-230g sodium chloroacetate is added successively, 40 DEG C-60 DEG C reactions after 3-10 hour, neutrality is neutralized to concentrated hydrochloric acid, then carry out successively dewatering, wash, dry, pulverize and screening, obtain enzymolysis-carboxymethylated starch;
(3) above-mentioned enzymolysis-carboxymethylated starch is dissolved in water, is made into the solution of 10%-60%, and add the sanitas of 0.1%-0.5%, the defoamer of 0.1%-0.5% can obtain starchiness humectant for smoke.
In the present invention, described starch is W-Gum, Starch rice, wheat starch, barley starch, sorghum starch, yam starch, tapioca (flour), sweet potato starch, green starch, pea starch, bajiao banana starch, sago starch and waxy starch as any one or its mixing in waxy corn starch, Waxy Rice Starch, wax sorghum starch.
Sodium chloroacetate can carry out equivalent substitution with Mono Chloro Acetic Acid.
In ethanol/water solution, the mass ratio of ethanol and water is 60:40-90:10.
Humectant of the present invention is evenly sprayed on tobacco leaf in tobacco feeding operation, the degrading resistance property of tobacco can be improved, reduce tobacco leaf making in the course of processing broken, reduce the tobacco leaf consumption of cigarette, and the jealous and effect such as mouthfeel, the stimulation of reduction flue gas can also be improved, serve the effect simultaneously improving the humectation of tobacco physics and sense organ humectation.
The consumption of humectant is the 0.1%-1.5% of quality of tobacco.
Advantage of the present invention is raw materials used for starch, and starch belongs to renewable resources, and wide material sources, cheap; By carrying out enzymolysis modified and carboxymethyl-modification to starch, make it have extremely strong water suction and water retention capacity, and environmental protection, with low cost.By adding the starchiness humectant for smoke in the present invention, the degrading resistance property of tobacco can not only be improved, reduce tobacco leaf making in the course of processing broken, reduce the tobacco leaf consumption of cigarette, and the jealous and effect such as mouthfeel, the stimulation of reduction flue gas can also be improved, serve the effect simultaneously improving the humectation of tobacco physics and sense organ humectation.
