Technical Field

The invention relates to a functional additive for a cigarette filter stick, in particular to a functional additive prepared from lauryl sodium sulfate and rosin active components, and also relates to application of the functional additive in reducing ammonia release amount in main stream smoke of a cigarette in the cigarette filter stick, belonging to the technical field of cigarette preparation.

Background

Ammonia, colorless and having a strong pungent odor, can burn the skin, eyes, mucous membranes of respiratory organs, and cause lung swelling and death due to excessive inhalation. Is a toxic substance, and the damage of the blood ammonia increase to the cranial nerve tissue is most obvious. Is one of the main harmful substances in the smoke. The content of ammonia in fresh tobacco leaves is low, and the content of ammonia is increased due to the metabolism (oxidation, deoxidation and other reactions) of protein and amino acid after the tobacco leaves are prepared and fermented. Amino acids, proteins, nitrates and ammonium salts in tobacco leaves are precursors of ammonia in cigarette smoke. In cigarettes, a moderate amount of ammonia is necessary for cigarettes with a high content of carbohydrates and organic acids, which, together with other nitrogen-containing compounds, participate in the development of a strong draught of the smoke. The ammonia content is too low, so that the smoke strength is reduced, and the fullness is not enough; however, excessive ammonia can cause strong irritation, which can cause the throat of smokers to shrink, which makes them feel choked and have hard to feel spicy in the nasal cavity and tongue. Therefore, the ammonia plays an important role in controlling the smoking taste of the cigarette. Therefore, the reduction of the ammonia content in the mainstream smoke of cigarettes and the improvement of smoking safety have become the targets of international consensus and pursuit at present, and are also one of the important research subjects to be solved in the development of the tobacco industry.

Currently, there is less literature on reducing ammonia in mainstream smoke of cigarettes as the only target of selectivity. Chinese patent (application No. 201010288157.0) discloses a cigarette processing method for reducing ammonia content, which is realized by mainly changing cigarette filament making process by utilizing microwave. Chinese patent application No. 201210041550.9, which is incorporated herein by reference, deals with the treatment of finished cigarettes or tobacco leaves by means of electron beam/X-ray irradiation. And Chinese patent (application No. 201210197501.4) adopts the method that an active component protoporphyrin compound is added into a filter stick. The tar and other harmful substances can be simultaneously reduced through the blocking and adsorption of the solid substances, but the effect is not as obvious as that reported when the solid substances are applied to the medium and low tar cigarettes, the reduction range of the tar is higher than that of the harmful substances, and the requirement of reducing the harmful components in the cigarette smoke with high selectivity cannot be met. Moreover, the patent technologies relate to the problems of complex process or high safety and high cost of active components, so that the application prospect has certain difficulty.

It can be shown that the two have obvious synergistic effect on the action of ammonia. And when the mass ratio of the sodium dodecyl sulfate to the rosin reaches about 1:9, the effect of selectively reducing the ammonia release amount is particularly outstanding.

The full dissolution and dispersion of the sodium dodecyl sulfate and the rosin in the solution can be ensured in the preferable temperature range, and the uniform loading on the calcium alginate particles is facilitated.

In a preferred embodiment, the calcium alginate particles are prepared by the following method: and (3) dropwise adding the sodium alginate solution into the calcium chloride solution, and standing for reaction to obtain the calcium alginate-calcium chloride composite.

In a preferable scheme, the mass ratio of the sodium alginate to the calcium chloride is 1: 4-8.

In the preferable scheme, the standing reaction time is 1-2 hours. The reaction is carried out for a long enough time to ensure the reaction is complete.

The preparation method of the calcium alginate granules comprises the following steps: uniformly scattering a certain amount of sodium alginate into distilled water, stirring at the temperature of 55 ℃ for 45min in a water bath at 300r/min to form a sodium alginate aqueous solution, dripping the sodium alginate aqueous solution into a calcium chloride aqueous solution by using a syringe with a needle head with the diameter of 2.5mm, standing for 1h, taking out solid particles, performing suction filtration, and washing with water to obtain the newly-prepared calcium alginate.

In a preferred scheme, the preparation method of the mixed solution containing the sodium dodecyl sulfate and the rosin comprises the following steps: mixing a rosin solution with the mass percentage concentration of 15-25% with a sodium dodecyl sulfate solution with the mass percentage concentration of 5-15%, and reacting for 3-5 hours at the temperature of 35-45 ℃.

The drying process of the invention adopts an infrared lamp for drying for 4 hours.

The invention also provides application of the cigarette filter stick additive with the function of reducing the ammonia release amount in the main stream smoke of the cigarette, and the cigarette filter stick additive is used as the functional additive with the function of reducing the ammonia content in the main stream smoke of the cigarette for a cigarette filter stick.

According to the preferable scheme, the additive amount of the cigarette filter stick additive in the cigarette filter stick tow is measured according to 20-40 mg per cigarette filter stick.

Compared with the prior art, the technical scheme of the invention has the following beneficial technical effects:

1) according to the invention, the lauryl sodium sulfate and the rosin are used as active components for adsorbing ammonia in smoke and can selectively react with the ammonia in the mainstream smoke, so that the harmful substances in the cigarettes are reduced, and the harm to smokers is reduced.

2) The invention utilizes calcium alginate particles to load sodium dodecyl sulfate and rosin, and has the advantages of stable load, good active component dispersibility and high safety.

3) The sodium dodecyl sulfate and the rosin adopted by the invention have good stability, and the selection range of harm-reducing materials is widened.

4) The preparation method of the cigarette filter stick additive is simple, has low cost and meets the requirement of industrial production.
