Embodiment 1

[0019] Example 1. Add 350g of tapioca starch into water to make 30% starch milk, adjust the pH of the system to about 6, then add 6.2mg of medium-temperature α-amylase (enzyme activity is 100,000U / g), and react at 75°C After 100 minutes, the enzyme was inactivated, followed by cooling, dehydration, drying, crushing and sieving to obtain the enzymatic starch. Add enzymatic starch to ethanol / water (V / V=65:35) solution to make 36% starch milk, then add 35g sodium hydroxide and 60g sodium chloroacetate in sequence, and react at 45°C for 6 hours, Neutralize to neutral with concentrated hydrochloric acid, then dehydrate, wash, dry, pulverize and sieve in sequence to obtain enzymatic hydrolysis-carboxymethylated starch. Dissolve enzymatic-carboxymethylated starch in water to prepare a 40% solution, and add 0.2% preservative and 0.3% defoamer to obtain starchy tobacco humectant.

Embodiment 2

[0020] Example 2. Add 350g of potato starch into water to make 30% starch milk, adjust the pH of the system to about 6, then add 6mg of medium-temperature α-amylase (enzyme activity is 100,000U / g), and react at 75°C for 150min Finally, the enzyme is inactivated, followed by cooling, dehydration, drying, crushing and sieving to obtain enzymatic starch. Add enzymatic starch to ethanol / water (V / V=65:35) solution to make 36% starch milk, then add 120g sodium hydroxide and 120g chloroacetic acid in turn, react at 45°C for 6 hours, use Concentrated hydrochloric acid is neutralized to neutral, followed by dehydration, washing, drying, crushing and sieving to obtain enzymatic hydrolysis-carboxymethylated starch. Dissolve enzymatic-carboxymethylated starch in water to prepare a 40% solution, and add 0.15% preservative and 0.2% defoamer to obtain starchy tobacco humectant.

Embodiment 3

[0021] Example 3. Add 350g of cassava starch into water to make 30% starch milk, adjust the pH of the system to about 6, then add 40mg of high temperature-resistant α-amylase (enzyme activity is 10000U / g), and react at 100°C After 120 minutes, the enzyme was inactivated, followed by cooling, dehydration, drying, crushing and sieving to obtain enzymatic starch. Add enzymatic starch to ethanol / water (V / V=80:20) solution to make 37% starch milk, then add 70g sodium hydroxide and 150g sodium chloroacetate in sequence, and react at 45°C for 8 hours, Neutralize to neutral with concentrated hydrochloric acid, then dehydrate, wash, dry, pulverize and sieve in sequence to obtain enzymatic hydrolysis-carboxymethylated starch. Dissolve enzymatic-carboxymethylated starch in water, prepare a 40% solution, and add 0.2% preservative and 0.2% defoamer to obtain starchy tobacco humectant.

Abstract

The invention discloses a method for preparing a starchy cigarette humectant by enzymatic hydrolysis and carboxymethylation and a use of the starchy cigarette humectant. The starchy cigarette humectant is prepared from 350g of starch, 5-120mg of alpha-amylase, 400-1200g of an ethanol / aqueous solution, 30-120g of sodium hydroxide and 50-230g of sodium chloroacetate by enzymatic hydrolysis and carboxymethylation. The method utilizes starch as the raw material and starch is a renewable resource and has a wide resource and a low price. Through enzymatic hydrolysis modification and carboxymethylation modification of starch, the modified starch has very strong water absorption and water retention capability, is environmentally friendly and has a low cost. The starchy cigarette humectant is uniformly sprinkled on the tobacco leaf in a tobacco leaf processing process so that tobacco leaf processing resistance is improved, crushed tobacco leaves in the processing process are reduced, cigarette tobacco leaf consumption is reduced, a taste and mouth feel are improved, smoke irritation is reduced and physical moisture retention and sensorial moisture retention effects on tobacco are improved simultaneously.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and specifically relates to a preparation method and application of an enzymolysis-carboxymethylated starchy humectant for tobacco. 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,...
