Description

A kind of preparation method and application thereof of pyrolysis-oxidized starch matter humectant for smoke

 

Technical field

The invention belongs to technical field of cigarettes, a kind of preparation method and application thereof of pyrolysis-oxidized starch matter humectant for smoke specifically, this humectant environmental protection, with low cost, and there is the effect of 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, transportation, storage, sale and sucking process, humectant can keep moisture content in leaves effectively, increase the flexibility of tobacco leaf, improve the resistance to processing characteristics of tobacco, reduce tobacco leaf making in process broken, reduce the tobacco leaf consumption of cigarette.Meanwhile, humectant also has the effect that reduces flue gas stimulation, improves jealous and mouthfeel.

The humectant that current domestic tobacco productive corporation uses mainly contains the polyalcohols such as propane diols, glycerine and sorbierite.Propane diols and glycerine are mainly the petroleum chemicals take petroleum gas as raw material, expensive, though sorbierite low price humectation effect and aesthetic quality are slightly poor.Because propane diols has certain volatility, therefore there is when cigarette burning quite a few propane diols to enter flue gas and form tar, burnt unfavorable to falling.Research also shows that the thermal decomposition product of propane diols is mainly acetaldehyde and acetone in addition, and the thermal decomposition product of glycerine is mainly acetaldehyde and methacrylaldehyde, and the use of these traditional humectants can cause in flue gas the harmful substance contents such as acetaldehyde to raise.In addition, propane diols, glycerine and sorbierite consumption slightly greatly also can bring penetrating odor to flue gas, unfavorable to cigarette mouthfeel.

Therefore, efficient, the green safety of development of new, natural baccy humectant with low cost become an important directions of cigarette additive research field.Chinese patent CN200910273418.9 discloses a kind of phoenix caudal lobe volatile oil cigarette sense organ humectant extracting 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 alcohol extract.Chinese patent CN 200910273359.5 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 is mainly that Chinese medicine extract is through enzymolysis, macroporous resin column adsorption filtration, the concentrated polysaccharide humectant that obtains of Rotary Evaporators.But the problem such as above-mentioned these natural plant extracts humectant ubiquities preparation flow complexity, and cost is higher, raw material sources are few, is therefore not yet generally applied.

Summary of the invention

For the deficiencies in the prior art, the present invention is take starch as raw material, successively by pyrolysis modification and oxidation modification, prepared 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, in each glucose unit of composition starch polymer, contain three hydroxyls, a large amount of hydroxyls has given starch good water-retaining property.Pyrolysis modification in the present invention has reduced the molecular weight of starch, has strengthened water-solublely, and is conducive to improve the content of solids in humectant, thereby strengthens its water suction and water holding capacity; Oxidation modification in the present invention mainly changes into the hydroxyl oxygen in starch molecule and has the more carboxyl of strongly hydrophilic, improved greatly its water suction and water holding capacity, thus simultaneous oxidation modification also played to a certain extent reduce starch molecule amount, strengthen water-soluble, provide solid contents in humectant also to strengthen the effect of its water suction and water holding capacity.

The object of the invention is to be achieved through the following technical solutions:

A preparation method for pyrolysis-oxidized starch matter humectant for smoke, is to be prepared from through pyrolysis, oxidation modification by following raw material, in every 350g starch, adds: 65% red fuming nitric acid (RFNA) 2-20g, and ethanol/water solution 400-1200g, clorox 5-60g, concrete steps are:

(1) take 350g starch as raw material, add 2-20g 65% red fuming nitric acid (RFNA), after mixing, put in baking oven or other dry process reaction device, at 110 ℃-150 ℃ reaction 3-10 hour, then cooling, and neutralize, be dried, pulverize and sieve by 10% NaOH ethanol/water solution, obtain pyrolysis dextrin.

(2) pyrolysis dextrin is joined in ethanol/water solution, be made into the starch milk of 30%-44%, then regulate the pH value of starch milk to 8-10 with 5% sodium hydrate aqueous solution, in 1-2 hour, add 5-60g clorox, at 45 ℃-60 ℃ reaction 5-10 hour, in this external course of reaction, should constantly drip 5% sodium hydrate aqueous solution so that pH value stabilization at 8-10, after reaction finishes, the ethanol/water solution of the hydrochloric acid with 20% is neutralized to neutrality, and reduce excessive clorox with sodium sulfite, finally dewater successively, washing, dry, pulverize and screening, obtain pyrolysis-oxidized starch.

(3) pyrolysis-oxidized starch is dissolved in water, is made into the solution of 10%-60%, and add the anticorrisive agent of 0.1%-0.5%, the defoamer of 0.1%-0.5% can obtain starchiness humectant for smoke.

In the present invention, the mass ratio of described ethanol/water solution is 50:50-80:20.

Described starch is cornstarch, rice starch, wheaten starch, barley starch, sorghum starch, farina, tapioca, starch from sweet potato, 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.

65% red fuming nitric acid (RFNA) can carry out equivalent replacement with the concentrated sulfuric acid, SPA etc.

Clorox can carry out equivalent replacement with hydrogen peroxide, potassium permanganate etc.

Humectant of the present invention is evenly sprayed on tobacco leaf in tobacco feeding operation, can improve the resistance to processing characteristics of tobacco, reduce tobacco leaf making in process broken, reduce the tobacco leaf consumption of cigarette, and can also improve the effects such as jealous and mouthfeel, the stimulation of reduction flue gas, play the effect of 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 resource, and wide material sources, cheap; By starch is carried out to pyrolysis modification and oxidation modification, make it have extremely strong water suction and water holding capacity, and environmental protection, with low cost.By adding the starchiness humectant for smoke in the present invention, can not only improve the resistance to processing characteristics of tobacco, reduce tobacco leaf making in process broken, reduce the tobacco leaf consumption of cigarette, and can also improve the effects such as jealous and mouthfeel, the stimulation of reduction flue gas, play the effect of simultaneously improving the humectation of tobacco physics and sense organ humectation.
