Example Embodiment

[0019] Example one:

[0020] Configure the retention agent according to the ratio listed in Table 1.

[0021] Table 1 Retaining agent ratio

[0022] Ingredients

[0023] Dissolve the prepared retention agent in the triacetin at a ratio of 6% (retention agent: triacetin = 6:100—mass ratio), and spray the retention agent into the filter rod according to the addition amount of 0.01mg , Adopting universal filter rod forming technology to form the filter rod at one time. During cigarette smoking, the retention agent reacts with crotonaldehyde, which effectively retains crotonaldehyde and reduces the harm of cigarette smoke. At the same time, the smoke becomes delicate and soft, and the smoking quality of the cigarette is improved. The changes of tar, crotonaldehyde and other components in the flue gas are shown in Table 2 and Table 3.

Example Embodiment

[0028] Embodiment two:

[0029] Configure the retention agent according to the ratio listed in Table 4.

[0030] Table 4 Proportion of retention agent

[0031] Ingredients

[0032] Dissolve the prepared retention agent in the triacetin according to a ratio of 10% (retention agent: triacetin=10:100—mass ratio), spray and add the retention agent to the filter rod according to the addition amount of 0.25mg , Adopting universal filter rod forming technology to form the filter rod at one time. During cigarette smoking, the retention agent reacts with crotonaldehyde, which effectively retains crotonaldehyde and reduces the harm of cigarette smoke. At the same time, the smoke becomes delicate and soft, and the smoking quality of the cigarette is improved. The changes of tar and crotonaldehyde in the flue gas are shown in Table 5 and Table 6.

[0040] Ingredients

[0041] Dissolve the prepared retention agent in the triacetin according to the ratio of 18% (retention agent: triacetin=18:100—mass ratio), spray and add the retention agent to the filter rod according to the addition amount of 0.5mg , Adopting universal filter rod forming technology to form the filter rod at one time. During cigarette smoking, the retention agent reacts with crotonaldehyde to effectively retain crotonaldehyde and reduce the smoke hazard of cigarettes. At the same time, the smoke becomes delicate and soft, and the smoking quality of the cigarette is improved. The changes of tar and crotonaldehyde in flue gas are shown in Table 8 and Table 9.

Abstract

The invention discloses an entrapment agent for selectively lowering crotonaldehyde content in cigarette smoke, which is obtained by mixing propylene glycol and glycerol at the volume ratio of 1:3 to 3:1 and then uniformly stirring. Meanwhile, the invention also discloses a filter stick with the entrapment agent, and the filter stick is prepared by adopting the following steps: (1) the entrapment agent is dissolved in plasticizer glycerol triacetate for forming tows, and during dissolution, the entrapment agent is 6-18% of the glycerol triacetate by mass percent to obtain an entrapment agent and glycerol triacetate mixed solution; and (2) in the tow forming process, the entrapment agent and glycerol triacetate mixed solution is sprayed to be added into a filter stick, and the additive amount of the entrapment agent is 0.01-0.5 mg so as to obtain the required filter stick. According to the invention, the crotonaldehyde content in the cigarette smoke can be remarkably lowered, meanwhile, the cigarette smoke moisture can be maintained, the smoke humidification is enhanced, the smoke quantity and the smoke quality are both improved and a cigarette is endowed with a better smoking feeling. The method and the formula are simple, the raw material source is wide and the cost is low.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to an intercepting agent and a filter rod for selectively reducing the content of crotonaldehyde in cigarette smoke. Background technique [0002] Aldehydes are one of the main gas phase components in cigarette smoke. Among them, the lower aldehydes have a strong irritating odor, and with the increase of the molecular weight, the irritating odor decreases, and the aroma is gradually produced. Studies have shown that the low-level aldehydes in cigarettes (mainly formaldehyde, acetaldehyde, acrolein and crotonaldehyde, etc.) have the toxicity of cilia, and will stimulate the sensory organs and respiratory system of the human body to varying degrees during cigarette smoking. cause serious harm to the human body. [0003] A portion of the aldehydes and ketones in the smoke vapor phase appear to be the result of direct transfer from tobacco, however, most of these volatile compounds...
