Problems solved by technology

For example, in Xu Ruanyuan's paper "Optimization of Rice Porous Starch Preparation Process and Its Application in Cigarette Filters", under the action of glucoamylase, by adjusting the enzyme activity, pH value, reaction time and reaction temperature in the reaction process The rice starch was hydrolyzed and modified under various conditions, and then a cross-linked esterified rice porous starch additive was prepared by cross-linking. The additive was added to the cigarette filter in an amount of 10 mg / stick, and the g filter could reduce the Ammonia content in cigarette mainstream smoke, but the preparation process of this method is cumbersome, the conditions for controlling the reaction are harsh, and industrial application is difficult

Embodiment 1

[0028] A preparation method and application of an additive for reducing ammonia content in cigarette mainstream smoke:

[0029] Weigh 1.5g of sodium alginate and 0.8g of calcium chloride and mix evenly, measure 10ml of absolute ethanol, heat and reflux for 1 hour, cool, filter, dry, grind and sieve, and take particles between 40 meshes to obtain a compound filter additives, sealed and protected from light.

[0030] Add the above filter additives to the cellulose acetate filter for compounding, the addition amount is 5mg / cig, 10mg / cig, 30mg / cig respectively, take the cellulose acetate filter without adding any additives as the blank control sample, and suck according to the standard Conditions The smoking experiment was carried out on a smoking machine, and the content of ammonia in the mainstream smoke of cigarettes was measured according to the standard method. The test results are shown in Table 1.

Embodiment 2

[0035] A preparation method and application of an additive for reducing ammonia content in cigarette mainstream smoke:

[0036] Weigh 1.5g sodium alginate, 0.3g D-galactopyranuronic acid and 0.2g calcium chloride and mix evenly, add 5ml deionized water, heat and reflux for 2 hours, cool, filter, dry, grind and sieve, The particles between 60 meshes are taken to obtain the filter tip additive, which is sealed and protected from light for preservation.

[0037] Add the above filter additives to the cellulose acetate filter for compounding, the addition amount is 5mg / cig, 10mg / cig, 30mg / cig respectively, take the cellulose acetate filter without any additive as the blank control sample, and follow the standard suction conditions The smoking experiment was carried out on the smoking machine, and the content of ammonia in the mainstream smoke of cigarettes was measured respectively according to the standard method, and the test results are shown in Table 2.

Embodiment 3

[0042] A preparation method and application of an additive for reducing ammonia content in cigarette mainstream smoke:

[0043] 1) Weigh alginic acid and humectant, and mix them evenly according to the mass ratio of 1:2 to obtain a mixture;

[0044] 2) Add water and ethanol mixed solvent (ratio 1:1) to the mixture obtained in step 1), and heat to reflux for 1 hour to obtain the additive;

[0045] The humectant is a mixture of potassium acetate, potassium oxalate and potassium lactate (ratio 1:1:1).

[0046] The amount of water and ethanol is sufficient to dissolve the moisturizing agent and immerse the mixture, and the specific amount is not limited.

[0047] After heating to reflux, the product can be cooled, filtered, dried, ground, sieved and so on. Afterwards, the additive is added into a cigarette filter rod for use. The additives are 20 mesh particles. The added amount of the additive is 5mg per bottle.

Abstract

The invention discloses a preparation method of an additive for reducing content of ammonia in mainstream smoke of cigarette. The preparation method comprises steps as follows: weighing alginic acid or alginate and humectant; uniformly mixing to obtain mixture; adding a solvent to the mixture; and heating and reflowing to obtain the additive. The invention also discloses application of the additive. According to the preparation method, raw materials are lower in cost, simple and convenient and easy to obtain; and the preparation method is safe and reliable, simple and convenient to operate, and easy for industrial mass production.

Description

technical field [0001] The invention belongs to the field of cigarettes, and in particular relates to a preparation method and application of an additive for reducing ammonia content in mainstream smoke of cigarettes. Background technique [0002] On the basis of the "Cigarette Hazard Index System Research", China has determined for the first time 7 indicators of the most harmful harmful components in mainstream cigarette smoke: CO, HCN, NNK, NH3, B[a]P, phenol, and crotonaldehyde. Among them, ammonia will not only shrink the smoker's throat and weaken the body's resistance to diseases, but also increase the intensity of the taste of cigarettes, resulting in stimulation and spicy taste, affecting the sensory quality of cigarettes. [0003] At present, there is no detailed research on the mechanism of ammonia in cigarette smoke at home and abroad. "Tobacco-Production, Chemistry and Technology" (Davis D L, Nielsen M T, Chemical Industry Press) mentioned that Johnson et al. fou...
