Preparation method of degraded starch tobacco humectant with mixed hydrolysis degrees

Abstract

The invention discloses a preparation method of degraded starch tobacco humectant with mixed hydrolysis degrees. The preparation method comprises the following steps of (1) adding starch into water with 4-times mass, stirring and mixing the starch and water, heating the mixture to 70 to 100 DEG C, and maintaining the temperature for 1h to 2h so as to enable the starch to be adequately gelatinized; (2) adding hydrochloric acid solution, uniformly stirring, heating the mixture to 60 to 90 DEG C to be reacted for 0.5h to 5h, cooling the mixture, adding alkali to neutralize the excessive acid to be neutral to obtain a starch degradation product with different hydrolysis degrees; (3) compounding the short-time hydrolyzed starch, the appropriately-hydrolyzed starch and the long-time hydrolyzed starch according to a ratio to obtain the mixed degraded starch tobacco humectant. The prepared humectant is rich in polyol and good in moistening effect; by containing polysaccharide molecules of different sizes, the prepared humectant can be better affined with pores in different sizes on the surface of tobacco, the film forming property is good, and the moistening and dampproof effect can be better realized.

Description

Technical field: [0001] The invention relates to a preparation method of a degraded starch tobacco moisturizer mixed with different hydrolysis degrees. Background technique: [0002] The moisture content of tobacco is an important factor related to tobacco quality. When the moisture content in the cut tobacco is too low, the irritation of the cigarette will increase, the dry mouth will be obvious, the impact on the throat will increase, and the tobacco aroma will decrease, the mouth residue will increase, and the tobacco quality will be somewhat different. decline. When the moisture content of the tobacco is too high, the material liquid will easily penetrate into the surface of the cigarette paper, and the cigarette will undergo color change and mildew, which will also cause the aroma to become stuffy, the permeability decreases, and the smoking quality decreases. Therefore, cigarette moisturizers need to play two functions of moisturizing and moisture-proof, which play an impo...

AI Technical Summary

Problems solved by technology

[0004] Starch, especially degraded starch, has been used in tobacco humectant. In the patent application with publication number CN103099308A, starch is hydrolyzed with acid and hydrogen peroxide, and starch is degraded into small molecule dextrin, which is then added to cigarettes as Tobacco moisturizer, but its moisturizing effect is not very ideal
