Abstract
The invention relates to a humectant for tobaccos and a preparation method thereof. The humectant is obtained by carrying out carboxymethylation on starch. The preparation method of the humectant comprises the following steps of: (1) adding 1,000g of starch into a hydrochloric acid solution, mixing and stirring for 10 min, reacting for 2-4h at a temperature of 100-120 DEG C to obtain white solids, and neutralizing the excessive acid to obtain dextrin; (2) adding the dextrin into 50% ethanol so that the concentration of the dextrin reaches up to 0.2-0.5g/mL, adding a mixture after being stirred evenly into a sealed flask, and stirring for 1h at a temperature of 40 DEG C; (3) adding a chloroacetic acid solution into the flask, heating up to 45-55 DEG C, and then reacting for 4-6h; and (4) filtering and drying to obtain the humectant. The starch can be derived from corn, potatoes, wheat and the like. The humectant for tobaccos and the preparation method thereof have the beneficial effects of improving the wettability of the tobaccos and being free from toxicity.
Description
Relate to the field: the present invention relates to a kind of humectant preparation field, be specifically related to a kind of humectant for smoke preparation field.
Technical background:
In production of cigarettes, transportation, storage, sale and sucking process, humectant has the maintenance moisture content in leaves, increases pliability, reduce make broken, reduce excitant and improve jealous effect.Therefore, very early before, the tobacco worker of various countries just begins to study on the humectation effect of various materials and on the impact that the jealous and smoke chemistry of cigarette forms, wherein most study is polyalcohols.
Nowadays, propane diols, glycerine and sorbierite are modal traditional tobacco humectants.But the humid keeping performance to tobacco is not high, and, certain toxicity is arranged.
Summary of the invention:
The purpose of this patent is exactly that deficiency for traditional tobacco humectant prepares a kind of humectant for smoke, improves the humid keeping performance of tobacco, and, avirulence.
The technical scheme of this patent is with the starch carboxy methylation, namely gets tobacco humectant, and preparation method's step is: (1) is with starch 1000 g, add hydrochloric acid solution, mix and blend 10 min obtain white solid at 100-120 ℃ of lower reaction 2-4 h, the excessive acid that neutralizes gets dextrin; (2) will add dextrin in 50% ethanol, make dextrin concentration reach 0.2-0.5g/mL, mix well in the airtight flask of rear adding, 40 ℃, stir 1 h; (3) chloroacetic acid solution is added in the flask, be warmed up to 45-55 ℃ of reaction 4-6 h, filter (4), drying, and get final product.Starch can be corn, potato, the starch in the multiple source such as wheat.
The invention has the beneficial effects as follows:
The present invention improves the humid keeping performance of tobacco, and, avirulence.Experimental result shows that the water imbibition of tobacco humectant of the present invention is 13.4%,, pipe tobacco under the condition of constant temperature and humidity, place 48 h after, its moisture content can remain on the relatively constant numerical value, corresponds to actual needs.
Specific implementation method:
Embodiment 1: with cornstarch 1000 g, add hydrochloric acid solution, mix and blend 10 min obtain white solid at 100-120 ℃ of lower reaction 2 h, and the excessive acid that neutralizes gets dextrin; To add dextrin in 50% ethanol, make dextrin concentration reach 0.2g/mL, mix well in the airtight flask of rear adding, 40 ℃, stir 1 h; Chloroacetic acid solution is added in the flask, be warmed up to 45 ℃ of reaction 4 h, filter, drying, and get final product.
Embodiment 2: with farina 1000 g, add hydrochloric acid solution, mix and blend 10 min obtain white solid at 120 ℃ of lower reaction 2 h, and the excessive acid that neutralizes gets dextrin; To add dextrin in 50% ethanol, make dextrin concentration reach 0.4g/mL, mix well in the airtight flask of rear adding, 40 ℃, stir 1 h; Chloroacetic acid solution is added in the flask, be warmed up to 55 ℃ of reaction 4 h, filter, drying, and get final product.
Embodiment 3: with wheaten starch 1000 g, add hydrochloric acid solution, mix and blend 10 min obtain white solid at 100 ℃ of lower reaction 4h, and the excessive acid that neutralizes gets dextrin; To add dextrin in 50% ethanol, make dextrin concentration reach 0.3g/mL, mix well in the airtight flask of rear adding, 40 ℃, stir 1 h; Chloroacetic acid solution is added in the flask, be warmed up to 45 ℃ of reaction 6 h, filter, drying, and get final product.
Claims (3)
1. a humectant for smoke is characterized in that: with the starch carboxy methylation, and get final product.
2. a humectant for smoke preparation method step, it is characterized in that: (1) adds hydrochloric acid solution with starch 1000 g, and mix and blend 10 min obtain white solid at 100-120 ℃ of lower reaction 2-4 h, and the excessive acid that neutralizes gets dextrin; (2) will add dextrin in 50% ethanol, make dextrin concentration reach 0.2-0.5g/mL, mix well in the airtight flask of rear adding, 40 ℃, stir 1 h; (3) chloroacetic acid solution is added in the flask, be warmed up to 45-55 ℃ of reaction 4-6 h; (4) filter, drying, and get final product.
3. according to claims 1 described starch, it is characterized in that: can be corn, potato, the starch in the multiple source such as wheat.
