Problems solved by technology

However, these patented technologies involve issues such as complex processes or the safety of active components, and are difficult to scale industrial production, so they basically have no application prospects
[0004] Chinese patent CN1612699 discloses a "cigarette and cigarette filter", claiming that injecting basic amino acid into the cigarette filter in the form of aqueous solution can be used to reduce the content of aldehydes in cigarette smoke, but there are many problems in this way: Adding a large amount of water in the filter will make the drying time too long, which is not conducive to large-scale industrial production; after 48 hours of conditioning and drying, the moisture content in the filter is still much higher than the level allowed by the tobacco industry, which will lead to cigarettes during the placement process. Mildew occurs. On the other hand, water is added to the filter to reduce harm (including aldehydes). This is well known in the tobacco industry. There are good reasons to believe that the moisture that is not completely dried in this patent is reducing smoke aldehydes. At the same time, during the drying process, amino acids can react with triacetin in the filter to produce odorous substances, which are not allowed as cigarette additives
Therefore, it basically has no application value

Embodiment 1

[0019] Prepare 10% glutamic acid solution with distilled water, weigh 50g of coarse-porous silica gel, slowly add glutamic acid solution into silica gel, stir evenly at the same time, soak in equal volume for 1 hour to make it fully infiltrated; Initiate a thermal reaction at ℃ and bake under this condition for 24 hours to fully react and dry the material, then cool to room temperature naturally, sieve to remove fine powder and take 40-60 mesh particles for use.

[0020] Add the prepared additive to the cigarette filter tip at 40 mg / stick, and the smoke test results show that the material can effectively reduce hydrocyanic acid (HCN) in smoke by 42.0%, formaldehyde by 39.7%, acetaldehyde by 10.0%, and crotonaldehyde by 15.4%. %, the specific detection data are shown in Table 1:

Embodiment 2

[0024] Prepare a 20% glycine solution with distilled water, weigh 50 g of activated carbon, slowly add the glycine solution to the activated carbon, stir evenly, and soak in equal volume for 2 hours to make it fully infiltrated; move the wet particles into an oven, and dry them for 10 hours at 150 ° C. The material is fully dried, cooled naturally to room temperature, sieved to remove fine powder and 40-60 mesh granules are used for later use.

[0025] Add the prepared additive to the cigarette filter at 40mg / piece, and the smoke test results show that the material can effectively reduce 24.6% of hydrocyanic acid (HCN) in the smoke, 29.3% of formaldehyde, 16.1% of acetaldehyde, and 26.2% of crotonaldehyde. %, the specific detection data are shown in Table 2:

Embodiment 3

[0029] Prepare 5% glutamine solution with distilled water, weigh 50g of alumina, slowly add glutamine solution to alumina, stir evenly at the same time, soak in equal volume for 2 hours to fully infiltrate; move the wet particles into an oven at 100°C Bake for 24 hours to make the material fully dry, cool to room temperature naturally, sieve to remove fine powder and take 40-60 mesh particles for use.

[0030] Add the prepared additive to the cigarette filter at 40 mg / piece, and the smoke test results show that the material can effectively reduce hydrocyanic acid (HCN) in smoke by 24.8%, formaldehyde by 43.2%, acetaldehyde by 8.1%, and crotonaldehyde by 14.7%. %, the specific detection data are shown in Table 3:

Abstract

The invention discloses an additive with a harm reducing function for a cigarette filter tip as well as preparation method and application method of the additive. According to the invention, one or more amino acids serve as active components, silica gel, active carbon, alumina, molecular sieve and the like serve as carriers, the active components are loaded on surfaces of the carriers through a surface chemical reaction to obtain a load-type amino acid material, the prepared load-type amino acid material is added into the cigarette filter tip to prepare a composite filter rod, and the composite filter rod is connected to a cigarette. Smoke analysis indicates that the cigarette containing the load-type amino acid material can effectively reduce 20-40% of hydrocyanic acid (HCN) and volatile carbonyl compounds in smoke; and the additive with the harm reducing function for the cigarette filter tip has the characteristics of safety, stability, simple preparation method, convenience for industrial production, capability of substantially no influence to the taste of the cigarette, and the like.

Description

technical field [0001] The invention belongs to the field of cigarette manufacturing, and in particular relates to a cigarette mouthpiece additive with harm reduction effect and a preparation and application method thereof. Background technique [0002] Hydrocyanic acid (HCN) and volatile carbonyl compounds are one of the main harmful substances in smoke, and also one of the important sources of environmental pollution. In severe cases, it may kill people within a few minutes, which is extremely harmful. Cigarette smoke contains aldehydes and ketones. It has been proved that aldehydes and ketones in the atmosphere have a strong stimulating effect on human eyes, skin and respiratory tract. Among them, formaldehyde and acrolein are carcinogenic to animals, and some other aldehydes Ketones are also very harmful to human health. Therefore, it is necessary to reduce these two types of harmful substances in the flue gas, and the data show that a large number of scientific and tec...
