Description

Filter tip additive for increasing filtering capacity of cigarette filter tip and preparation method and application thereof

Technical Field

The invention belongs to the technical field of tobacco, and particularly relates to a filter tip additive for increasing the filtering capacity of a cigarette filter tip, and a preparation method and application thereof.

Background

In recent years, with the progress of tar and harm reduction of tobacco, research on tobacco filters has been continuously conducted. The filter tip is used as a direct and effective physical tar and harm reducing means, and part of particulate matters and tar generated by burning tobacco are filtered on the filter tip through filtration. In order to seek better filtering effect, the effects of further reducing tar and harm are achieved by increasing the length of the filter tip, adding an adsorbent into the filter tip and the like.

At present, the domestic cigarette industry mainly adopts single substances such as activated carbon and the like as cigarette filter tip additives, and the effect is common. For example, patent CN2015104215702 discloses a preparation method and application of an embedded activated carbon filter adsorption additive, which is obtained by pretreating activated carbon, colloidal solution and sodium stearate, and can effectively and selectively reduce the content of various components in cigarette smoke without bringing about the negative effect of active component migration, but the effect is general. In addition, the adsorption capacity of the conventional additive to the filter tip can not be changed along with the smoking of the cigarette, and the adsorption capacity can be reduced in some cases, but the filtering effect of the tobacco shreds is reduced along with the burning of the cigarette, and meanwhile, the enrichment of harmful substances can cause the relative increase of the harmful substances.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the filter tip additive for increasing the filtering capacity of the cigarette filter tip, and the filter tip additive can better reduce the contents of total particulate matters and tar in cigarettes, thereby more effectively reducing tar and harm.

The invention also provides a preparation method and application of the filter tip additive for increasing the filtering capacity of the cigarette filter tip.

In order to achieve the purpose, the invention adopts the following technical scheme:

a filter tip additive for increasing the filtering capacity of a cigarette filter tip is composed of the following raw materials in percentage by mass: 5 to 10 percent of carrageenan, 5 to 12 percent of xanthan gum, 10 to 20 percent of guar gum, 10 to 19 percent of sodium alginate, 20 to 30 percent of agar and 18 to 50 percent of active carbon.

A preparation method of the filter tip additive for increasing the filtering capacity of the cigarette filter tip specifically comprises the following steps: weighing the raw materials according to the proportion, fully and uniformly mixing to obtain the product, sealing, drying and storing in dark place.

The invention also provides application of the filter tip additive for increasing the filtering capacity of the cigarette filter tip in cigarettes.

Specifically, the filter additive for increasing the filtering capacity of the cigarette filter can be added into a two-section filter or a three-section filter by 0.1-0.3% of the mass of the filter in the section.

Specifically, above-mentioned increase cigarette filter tip filter ability's application in the cigarette can add this filter tip additive at the interlude that is close to tobacco shred section or syllogic filter of two segmentation filters.

In the invention, the carrageenan has strong stability, and the dry powder is not easy to degrade after being placed for a long time. It is also stable in neutral and alkaline solutions and does not hydrolyze even when heated, and is commonly used in the food industry as a thickener, gelling agent, suspending agent, emulsifier, stabilizer, and the like. Xanthan gum is white or light yellow powder, has excellent thickening property, suspension property, emulsifying property and water solubility, and has good heat and acid-base stability, so that the xanthan gum is widely applied to various foods. Guar gum and its derivatives have better water solubility and exhibit very high viscosity at low mass fractions. Sodium alginate belongs to natural polysaccharide, and has the stability, solubility, viscosity and safety required by pharmaceutical preparation auxiliary materials. Sodium alginate is also used in some liquid drugs to increase viscosity and improve suspension of solids. Agar is a hydrophilic colloid extracted from red seaweed, and belongs to food additive. The activated carbon has the characteristics of large surface area, strong adsorption force, high purity, high filtration speed, stable quality, flocculation effect, filtration assisting effect and the like.

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

1) the cigarette filter additive can better reduce the contents of total particulate matters and tar in cigarettes;

2) the additive of the cigarette filter tip of the invention shortens with the burning of the cigarette, the humidity in the filter tip becomes large, wherein the additive gradually increases the adsorption capacity to substances such as tar and the like after absorbing water, and more effectively plays a role in reducing tar and harm;

3) the filter additive can be directly added on the basis of a two-section filter or a three-section filter, and the adopted filter additive raw materials are nontoxic and pollution-free;

4) the filter tip additive has the advantages of simple preparation method, strong practicability and good application prospect.

Detailed Description

The technical solution of the present invention is further described in detail with reference to the following examples, but the scope of the present invention is not limited thereto.

The concrete implementation is carried out according to the conventional technology in the field by people who are not specially noted, and the raw materials are all common products which can be purchased.
