Embodiment 1

[0020] Embodiment 1. 350g of rice starch is added into water, adjusted into 38% starch milk, then add 50g37% concentrated hydrochloric acid, after mixing evenly, react at 50 ℃ for 8 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=60:40) solution to make 37% starch milk, then use 2% sodium hydroxide aqueous solution to adjust the pH value of starch milk to 8-10. Add 22g sodium hypochlorite within 1-2 hours, and react at 52°C for 7 hours. In addition, during the reaction process, 2% sodium hydroxide aqueous solution should be added dropwise to stabilize the pH value at 8-10. After the reaction, use 10 % hydrochloric acid ethanol / water solution to neutralize to neutral, and reduce excess sodium hypochlorite with sodium sulfite, and finally dehydrate, wash, dry, crush and sieve in sequence ...

Embodiment 2

[0021] Embodiment 2. 350g of rice starch is added into water to make 38% starch milk, then add 60g of concentrated sulfuric acid, mix well, react at 50°C for 8 hours, then cool, and use 5% sodium hydroxide aqueous solution to neutralize and, finally dehydrating, washing, drying, pulverizing and sieving in sequence to obtain acid-thinned starch. Add acid-thinned starch to ethanol / water (V / V=60:40) solution to make 37% starch milk, then use 2% sodium hydroxide aqueous solution to adjust the pH value of starch milk to 8-10. Add 35g of sodium hypochlorite within 1-2 hours, and react at 52°C for 8 hours. In addition, during the reaction process, 2% aqueous sodium hydroxide solution should be added dropwise to stabilize the pH value at 8-10. After the reaction, use 10 % hydrochloric acid ethanol / water solution to neutralize to neutral, and reduce excess sodium hypochlorite with sodium sulfite, and finally dehydrate, wash, dry, crush and sieve in sequence to obtain acid-hydrolyzed-ox...

Embodiment 3

[0022] Embodiment 3. 350g of wheat starch is added to water, adjusted into 38% starch milk, then add 100g37% concentrated hydrochloric acid, after mixing evenly, react at 53 ℃ 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=60:40) solution to make 38% starch milk, then use 2% sodium hydroxide aqueous solution to adjust the pH value of starch milk to 8-10. Add 60g of hydrogen peroxide within 1-2 hours, and react at 53°C for 11 hours. In addition, during the reaction process, 2% sodium hydroxide aqueous solution should be added dropwise to stabilize the pH value at 8-10. After the reaction, use 10 % hydrochloric acid ethanol / water solution to neutralize to neutral, and reduce excess hydrogen peroxide with sodium sulfite, and finally dehydrate, wash, dry, crush and sieve in sequence...

Abstract

The invention relates to a preparation method and an application of an acidolyzed-oxidized amyloid cigarette humectant. The humectant is prepared through acidolysis and oxidation 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 a water solution and 20-70 g of sodium hypochlorite. 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 oxidation 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 acid-hydrolyzed-oxidized starch-based humectant for tobacco. Moisturizing effect for the senses. 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, glycerin ...
