Problems solved by technology

If the molecular weight of the humectant is too small, it will be difficult to form a film on the surface of the cut tobacco. If the molecular weight of the humectant is too large, it will be difficult for the humectant to infiltrate into the micropores of the shredded tobacco, which will affect the moisturizing effect of the humectant.
Conventional tobacco humectants are usually small molecule humectants or starch-modified humectants, and these humectants can only meet the moisturizing needs of shredded tobacco to a certain extent

Embodiment

[0018] Example: The tobacco humectant with molecular weight gradient distribution in this example, its formulation is calculated by weight percentage, and includes the following substances: 20 wt% of propylene glycol with a molecular weight ranging from 100 to 1000, 10% of glycerin, and 0.2 wt% of dextran with a molecular weight of 50000D , with a molecular weight in the range of 10 5 ~10 6 The guar gum is 0.01wt%, and the balance is water and accounts for 69.79wt%.

[0019] Dissolve guar gum and dextran in water in sequence, then add corresponding amount of propylene glycol and glycerin, stir and dissolve to obtain humectant BR-01.

[0020] Add BR-01 to the cigarette material liquid at a ratio of 50%, and add it to the cigarette according to the method of addition to make a cigarette sample. The results are shown in Table 1 under different conditions compared with the cigarette products added with normal feed liquid and supplemented with corresponding amounts of propylene g...

Embodiment 2

[0025] The tobacco humectant with molecular weight gradient distribution in this embodiment, its formula is calculated by weight percentage, and includes the following substances: 20 wt% of propylene glycol with a molecular weight range of 100-1000, 10% of glycerin, 0.2 wt% of starch with a molecular weight range of 1000-100000, molecular weight in the range of 10 5 ~10 6 Potassium alginate is 0.005wt%, and the balance is water, accounting for 69.795wt%.

[0026] Dissolve potassium alginate and starch in water in turn, add propylene glycol and glycerin, stir and dissolve until homogeneous, and obtain humectant BR-02.

[0027] Add BR-02 to the cigarette material liquid at a ratio of 50%, and add it to the cigarette according to the method of addition to make a cigarette sample. The results are shown in Table 2 for comparison under different conditions with the cigarette products added with normal feed liquid and supplemented with corresponding amounts of propylene glycol and ...

Abstract

The invention discloses a tobacco humectant achieving gradient distribution of molecular weights. Raw materials of the tobacco humectant are distributed in a gradient mode according to the magnitudes of the molecular weights, and the tobacco humectant is composed of, by weight, 10%-40% of micromolecule humectants, 0.01%-2% of medium-molecular-weight humectants, 0.001%-0.05% of high-molecular-weight humectants and 57.95%-89.98% of water. According to the sequence from high molecular weights to low molecular weights, the raw materials of the tobacco humectant are sequentially dissolved in the water so as to form a homogeneous phase solution, and the tobacco humectant is obtained. The tobacco humectant is added to cigarette feeding liquid or expanded cut tobacco feeding liquid or cut stem feeding liquid or papermaking-method slice coating liquid according to the ratio of 1%-50%, the tobacco humectant is applied to cigarettes in a fed mode, and functions of the tobacco humectant are given into play.

Description

Technical field: [0001] The invention relates to a tobacco humectant with molecular weight gradient distribution. Background technique: [0002] Tobacco moisture is an important factor related to tobacco quality. When the moisture content of cut tobacco is too low, the irritation of cigarettes will increase, the mouth will feel dry, and the impact on the throat will increase, while the tobacco aroma will decrease, the residue in the mouth will increase, and the quality of tobacco will decline. . When the moisture content of the tobacco is too high, the feed liquid will easily seep into the surface of the cigarette paper, causing discoloration and mildew of the cigarette, which will also cause the defects of dull aroma, decreased permeability, and reduced smoking quality. Therefore, the humectant for cigarettes can perform two functions of moisturizing and moisture-proofing, and plays an important role in promoting the improvement of tobacco quality. [0003] Studies have s...
