Embodiment 1

[0012] Example 1: Add 500g of cornstarch to hydrochloric acid solution, mix and stir for 6min, react at 120°C for 1h to obtain a white solid, neutralize excess acid to obtain dextrin; mix dextrin and deionized water to form a 40% emulsion , adjust the pH to 10.0~11.0; raise the temperature to 40°C, add H2O2 dropwise, and react at constant temperature for 1 hour; adjust the pH to neutral; filter and dry to obtain the product.

Embodiment 2

[0013] Example 2: Add 500g of potato starch to hydrochloric acid solution, mix and stir for 6min, react at 150°C for 2h to obtain a white solid, neutralize excess acid to obtain dextrin; mix dextrin and deionized water to form a 70% emulsion , adjust the pH to 10.0~11.0; raise the temperature to 60 ℃, add H2O2 dropwise, and react at constant temperature for 1-2h; adjust the pH to neutral; filter, dry, and obtain.

Abstract

The invention relates to a preparation method of modified dextrin cigarette humectants. The preparation method includes steps of: (1) adding hydrochloric acid solution in 500g starch, mixing for 6 minutes, then reacting for 1-2 hours under 120-150 DEG C to obtain white solid, neutralizing excess acid to obtain dextrin, (2) blending the dextrin and deionized water into emulsion in 40%-70% concentration, regulating a pH value to 10.0-11.0, (3) heating up the emulsion to 40-60 DEG C, adding hydrogen peroxide dropwisely, and then reacting for 1-2 hours under constant temperature, (4) regulating the pH value to be neutral, (5) filtering, drying, and then obtaining the modified dextrin cigarette humectants. The starch can be starch of corn, potato, wheat and the like. The preparation method has the advantages that humidity preservation performance of tobacco is improved, and moreover the modified dextrin cigarette humectants are non-toxic.

Description

[0001] Related field: The present invention relates to the field of preparation of humectant, in particular to the field of preparation of modified dextrin humectant for tobacco. technical background: [0002] In the process of cigarette production, transportation, storage, sale and smoking, humectants can maintain the moisture of tobacco leaves, increase flexibility, reduce crushing, reduce irritation and improve taste. Therefore, a long time ago, tobacco workers in various countries began to study the moisturizing effect of various substances and their influence on the taste of cigarettes and the chemical composition of smoke, among which polyols are the most studied. [0003] Today, propylene glycol, glycerin, and sorbitol are the most common traditional tobacco humectants. But the moisture retention property to tobacco is not high, moreover, has certain toxicity. Invention content: [0004] The purpose of this patent is to prepare a modified dextrin humectant for tob...
