Embodiment 1

[0020] Example 1 .Add 350g of potato starch into water to make 30% starch milk, adjust the pH of the system to about 6, then add 5.5mg of medium-temperature α-amylase (enzyme activity is 100,000U / g), react at 75°C for 100min, Enzyme inactivation is carried out, followed by cooling, dehydration, drying, crushing and sieving to obtain enzymatic starch. Add enzymatic starch to ethanol / water (V / V=70:30) solution to make 36% starch milk, then use 2% sodium hydroxide aqueous solution to adjust the pH value of starch milk to 8-10. Add 19g of sodium hypochlorite within 1-2 hours, and react at 50°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, pulverize and sieve to obtain enzymatic-oxidized sta...

Embodiment 2

[0021] 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 7mg of medium-temperature α-amylase (enzyme activity is 100,000U / g), react at 75°C for 150min, and carry out Enzyme inactivation, followed by cooling, dehydration, drying, crushing and sieving to obtain enzymatic starch. Add enzymatic starch to ethanol / water (V / V=70:30) solution to make 36% starch milk, then use 2% sodium hydroxide aqueous solution to adjust the pH value of starch milk to 8-10. Add 30g of sodium hypochlorite within 1-2 hours and react at 50°C for 8 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, pulverize and sieve to obtain enzymatic-oxidized starch...

Embodiment 3

[0022] Example 3 .Add 350g of sorghum 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 / mL, react at 100°C for 120min, then carry out Inactivate the enzyme, and perform cooling, dehydration, drying, crushing and sieving in sequence to obtain the enzymatic starch.Add the enzymatic starch to the ethanol / water (V / V=75:25) solution to make 37% starch milk , and then use 2% sodium hydroxide aqueous solution to adjust the pH value of starch milk to 8-10, add 45g potassium permanganate within 1-2 hours, and react at 50°C for 10 hours. In addition, during the reaction process, it should be continuously Add 2% aqueous sodium hydroxide solution dropwise to stabilize the pH value at 8-10. After the reaction, neutralize to neutral with 10% ethanol / water solution of hydrochloric acid, and reduce excess potassium permanganate with sodium sulfite, and finally Carry out dehydrat...

Abstract

A preparation method and application of an enzymolysis-oxidized starch-based humectant for tobacco, characterized in that: the humectant is prepared from the following raw materials through enzymolysis and oxidation modification, and is added to every 350g of starch: α- Amylase 5-120mg, ethanol / water solution 400-1200g, sodium hypochlorite 15-65g. The advantage of the present invention is that the raw material used is starch, which is a renewable resource, and has a wide range of sources and low price; through enzymatic modification and oxidative modification of starch, it has strong water absorption and water retention capabilities, and is environmentally friendly ,low cost. The humectant of the present invention is evenly sprayed on the tobacco leaves in the tobacco leaf feeding process, which can improve the processing resistance of the tobacco, reduce the crushing of the tobacco leaves in the processing process, reduce the consumption of the tobacco leaves of the cigarette, and improve the taste and mouthfeel, Reduce smoke stimulation and other effects, and play the effect of simultaneously improving the physical moisture retention and sensory moisture retention of tobacco.

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-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 and ...
