Embodiment 1

[0019] Example 1. Weigh 350g of wheat starch, add 4g of concentrated sulfuric acid dropwise, stir and mix evenly, put it into a self-made dry reactor, react at 130°C for 5 hours, and neutralize it with 10% sodium hydroxide ethanol aqueous solution after cooling , and then dried, crushed and sieved to obtain pyrolytic dextrin. Add pyrolytic dextrin to ethanol / water (V / V=60:40) solution to make 37% starch milk, then add 20g sodium hydroxide and 40g sodium chloroacetate in sequence, and react at 45°C for 5 hours , neutralized to neutral with concentrated hydrochloric acid, and then dehydrated, washed, dried, crushed and sieved in sequence to obtain pyrolysis-carboxymethylated starch. Dissolving the pyrolyzed-carboxymethylated starch in water to form a 40% aqueous solution, adding 0.2% preservative and 0.2% defoamer to obtain the starchy humectant for cigarettes.

Embodiment 2

[0020] Example 2. Weigh 350g of potato starch, add 9g of concentrated sulfuric acid dropwise, stir and mix evenly, put it into a self-made dry reactor, react at 140°C for 7 hours, and neutralize it with 10% sodium hydroxide ethanol aqueous solution after cooling , and then dried, crushed and sieved to obtain pyrolytic dextrin. Add pyrolytic dextrin to ethanol / water (V / V=60:40) solution to make 37% starch milk, then add 50g sodium hydroxide and 80g sodium chloroacetate in sequence, and react at 45°C for 5 hours , neutralized to neutral with concentrated hydrochloric acid, and then dehydrated, washed, dried, crushed and sieved in sequence to obtain pyrolysis-carboxymethylated starch. Dissolving the pyrolyzed-carboxymethylated starch in water to form a 40% aqueous solution, adding 0.2% preservative and 0.2% defoamer to obtain the starchy humectant for cigarettes.

Embodiment 3

[0021] Example 3. Weigh 350g of wheat starch, add 15g of concentrated phosphoric acid dropwise, stir and mix evenly, put it into a self-made dry reactor, react at 150°C for 10 hours, and neutralize it with 10% sodium hydroxide ethanol aqueous solution after cooling , and then dried, crushed and sieved to obtain pyrolytic dextrin. Add 300g of pyrolytic dextrin into ethanol / water (V / V=70:30) solution to make 37% starch milk, then add 80g of sodium hydroxide and 150g of sodium chloroacetate in turn, and react at 45°C After 5 hours, it was neutralized to neutral with concentrated hydrochloric acid, and then dehydrated, washed, dried, crushed and sieved in sequence to obtain pyrolysis-carboxymethylated starch. Dissolving the pyrolyzed-carboxymethylated starch in water to form a 40% aqueous solution, adding 0.2% preservative and 0.2% defoamer to obtain the starchy humectant for cigarettes.

Abstract

A preparation method and application of a pyrolysis-carboxymethylated starch-based humectant for cigarettes, characterized in that: the humectant is prepared from the following raw materials through pyrolysis and carboxymethylation modification, each 350g Add to starch: concentrated sulfuric acid 2-25g, ethanol / water solution 400-1200g, sodium hydroxide 10-110g, sodium chloroacetate 20-220g. 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 certain pyrolysis modification and carboxymethylation modification of starch, it has extremely strong water absorption and water retention capacity, and green environmental protection, low cost. Evenly spraying the humectant of the present invention on the tobacco leaves in the tobacco leaf feeding process can improve the processing resistance of the tobacco, reduce the crushing of the tobacco leaves during processing, reduce the tobacco leaf consumption of cigarettes, 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 method for preparing a pyrolysis-carboxymethylated starchy tobacco humectant and its application. 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, gly...
