Embodiment 1

[0020] Embodiment 1. 350g of sweet potato starch is added into water, adjusted into 38% starch milk, then add 40g37% concentrated hydrochloric acid, after mixing evenly, react at 50 ℃ for 9 hours, then cool, and carry out with 5% sodium hydroxide aqueous solution Neutralization, and finally dehydration, washing, drying, crushing and sieving in sequence to obtain acid-thinned starch. Add acid-thinned starch to ethanol / water (V / V=75:25) solution to make 37% starch milk, then add 80g sodium hydroxide and 65g chloroacetic acid in turn, react at 45°C for 5 hours, use 37% concentrated hydrochloric acid is neutralized to neutral, and then dehydrated, washed, dried, crushed and sieved in sequence to obtain pyrolysis-carboxymethylated starch. Dissolve the acid-hydrolyzed-carboxymethylated starch in water to make a 40% solution, and add 0.3% preservative and 0.3% defoamer to obtain the starchy tobacco humectant.

Embodiment 2

[0021] Embodiment 2. 350g sweet potato starch is added into water, adjusted into 38% starch milk, then add 70g37% concentrated hydrochloric acid, after mixing, react at 50 ℃ for 10 hours, then cool, and carry out with 5% sodium hydroxide aqueous solution Neutralization, and finally dehydration, washing, drying, crushing and sieving in sequence to obtain acid-thinned starch. Add acid-thinned starch to ethanol / water (V / V=75:25) solution to make 37% starch milk, then add 65g sodium hydroxide and 135g sodium chloroacetate in sequence, and react at 45°C for 6 hours, Neutralize to neutral with 37% concentrated hydrochloric acid, then dehydrate, wash, dry, pulverize and sieve in sequence to obtain acid-hydrolyzed-carboxymethylated starch. Dissolve the acid-hydrolyzed-carboxymethylated starch in water to make a 40% solution, and add 0.3% preservative and 0.3% defoamer to obtain the starchy tobacco humectant.

Embodiment 3

[0022] Embodiment 3. 350g of barley starch is added to water, adjusted to 38% starch milk, then add 90g of concentrated nitric acid, after mixing evenly, react at 53°C for 12 hours, then cool, and carry out neutralization with 5% sodium hydroxide aqueous solution and, finally dehydrating, washing, drying, pulverizing and sieving in sequence to obtain acid-thinned starch. Add acid-thinned starch to ethanol / water (V / V=75:25) solution to make 38% starch milk, then add 80g sodium hydroxide and 170g sodium chloroacetate in turn, react at 45°C for 9 hours, Neutralize to neutral with 37% concentrated hydrochloric acid, then dehydrate, wash, dry, pulverize and sieve in sequence to obtain acid-hydrolyzed-carboxymethylated starch. Dissolve acid-hydrolyzed-carboxymethylated starch in water to make a 40% solution, and add 0.2% preservative and 0.2% defoamer to obtain starchy tobacco humectant.

Abstract

The invention relates to a preparation method and an application of an acidolyzed-carboxymethylated amyloid cigarette humectant. The humectant is prepared through acidolysis and carboxymethylation modifications and by using the following raw materials: based on every 350 g of starch, 10-150 g of 37% concentrated hydrochloric acid, 400-1,200 g of an ethanol / water solution, 20-110 g of sodium hydroxide and 40-210 g of sodium chloroacetate. The preparation method is advantageous in that the starch is used as a raw material; the starch belongs to renewable resources, is widely available and has low cost; the starch is subjected to some acidolysis modification and carboxymethylation modification, so that the modified starch has very strong water absorption and water retention capacities. The preparation method is environment-friendly and is low in cost. By spraying the humectants provided by the invention on tobacco leaves uniformly during a tobacco leaf-adding process, processing resistance of the tobacco can be increased; crushing of the tobacco leaves in the processing process can be reduced; tobacco leaf consumption of the cigarette is reduced; taste and flavor of the cigarette can be improved; stimulation of smoke can be alleviated; and effects for improving physical moisture preservation and sense moisture preservation can be achieved at the same time.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and specifically relates to a preparation method and application of an acidolysis-carboxymethylated starchy tobacco humectant. Moisturizing and sensual moisturizing effect. Background technique [0002] Humectants are an indispensable additive in the production process of cigarettes. During the production, transportation, storage, sales and smoking of cigarettes, humectants can effectively maintain the moisture of tobacco leaves, increase the softness of tobacco leaves, and improve the durability of tobacco leaves. Processing performance, reduce the crushing of tobacco leaves during processing, and reduce the consumption of tobacco leaves in cigarettes. At the same time, the humectant also has the effect of reducing smoke irritation and improving taste and taste. [0003] At present, the humectants used by domestic cigarette manufacturers mainly include polyols such as propylene glycol, glyc...
