Embodiment 1

[0024] Example 1. Add 350g of waxy cornstarch to ethanol / water (V / V=70:30) solution to make 37% starch milk, add 35g of sodium hypochlorite within 1-2 hours, and react at 50°C for 6 hours. In addition, during the reaction process, 2% sodium hydroxide aqueous solution should be continuously added dropwise to stabilize the pH value at neutral. After the reaction is over, reduce the excess sodium hypochlorite with sodium sulfite, and finally dehydrate, wash, dry, pulverize and sieve. points to obtain oxidized starch. Add g of oxidized starch to ethanol / water (V / V=80:20) solution to make 37% starch milk, then add 36g of sodium hydroxide and 70g of sodium chloroacetate in sequence, and react at 45°C for 7 hours, Neutralize to neutral with concentrated hydrochloric acid, then dehydrate, wash, dry, pulverize and sieve in sequence to obtain oxidized-carboxymethylated starch. Dissolve oxidized-carboxymethylated starch in water to prepare a 40% solution, and add 0.2% preservative and ...

Embodiment 2

[0025] Example 2. Add 350g of waxy corn starch to ethanol / water (V / V=70:30) solution to make 37% starch milk, add 48g of potassium permanganate within 1-2 hours, and react at 50°C 8 hours. In addition, during the reaction process, 2% sodium hydroxide aqueous solution should be continuously added dropwise to stabilize the pH value at neutral. After the reaction, the excess potassium permanganate was reduced with sodium sulfite, and finally dehydration and washing were carried out respectively. , drying, pulverizing and sieving to obtain oxidized starch. Add oxidized starch to ethanol / water (V / V=80:20) solution to make 37% starch milk, then add 108g sodium hydroxide and 130g chloroacetic acid in turn, react at 45°C for 7 hours, and use concentrated The hydrochloric acid is neutralized to neutrality, and then dehydration, washing, drying, crushing and sieving are carried out in sequence to obtain oxidized-carboxymethylated starch. Dissolve oxidized-carboxymethylated starch in w...

Embodiment 3

[0026] Example 3. Add 350g waxy corn and rice starch to ethanol / water (V / V=70:30) solution to make 38% starch milk, add 73g sodium hypochlorite within 1-2 hours, and react at 53°C for 10 hours In addition, during the reaction process, 2% aqueous sodium hydroxide solution should be continuously added dropwise to stabilize the pH value at neutral. After the reaction is over, reduce the excess sodium hypochlorite with sodium sulfite, and finally dehydrate, wash, dry, pulverize and Sieve to obtain oxidized starch. Add oxidized starch to ethanol / water (V / V=80:20) solution to make 38% starch milk, then add 90g sodium hydroxide and 178g sodium chloroacetate in sequence, react at 45°C for 9 hours, use Concentrated hydrochloric acid is neutralized to neutral, followed by dehydration, washing, drying, crushing and sieving to obtain oxidized-carboxymethylated starch. Dissolve oxidized-carboxymethylated starch in water to prepare a 40% solution, and add 0.2% preservative and 0.2% defoam...

Abstract

The invention relates to a preparation method and an application of an oxidized-carboxymethylated amyloid cigarette humectant. The humectant is prepared through oxidization and carboxymethylation modifications and by using the following raw materials: based on every 350 g of starch, 30-90 g of sodium hypochlorite, 800-2,400 g of an ethanol / water solution, 10-100 g of sodium hydroxide and 20-210 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 oxidization 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

[0001] technical field [0002] The invention belongs to the technical field of cigarettes, and specifically relates to a preparation method and application of an oxidized-carboxymethylated starchy tobacco humectant. Moisturizing and sensory moisturizing effect. [0003] Background technique [0004] 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. [0005] At present, the humectants used by domestic cigarette manufacturers mainly include polyols such as propy...
