Filter additive for reducing content of hydrocyanic acid in smoke of cigarette and preparation method thereof

Abstract

The invention discloses a filter additive for reducing the content of hydrocyanic acid in the smoke of a cigarette and a preparation method thereof. The preparation method comprises the following steps: mixing starch and transitional metallic salts, dipping the mixture with buffer solution of acetic acid, carrying out enzymolysis with diastatic enzyme, drying, crushing and screening to obtain metal dipping modified porous starch particles, namely the needed filter additive. When being applied to the filter of the cigarette, the particles not only have better selective removing for HCN, but also have no adverse influence on reduction of other harmful gases. As the amount of added metal is little, the filter additive has less influence on the flavor of the cigarette. The adsorption efficiency of the product is not reduced obviously after being stored for six months, even longer time. The invention has simple and convenient preparation technique, reliable quality and very stable attachment of transitional metallic ions, and can be applied to all the filters of the cigarettes with known forms.

Description

technical field [0001] The invention belongs to the technical field of cigarette additives, in particular to a filter tip additive capable of significantly reducing the content of hydrocyanic acid in cigarette smoke. At the same time, the invention also relates to a preparation method of the filter tip additive. Background technique [0002] It is an indisputable fact that smoking is harmful to health. In recent years, more and more attention has been paid to the research on how to reduce the harmful components in cigarette smoke in our country. The State Tobacco Monopoly Administration organized the research on 29 harmful substances and 4 toxicological indicators of 163 kinds of domestic and foreign cigarettes, using data mining techniques such as genetic algorithm and non-informative variable deletion method, and found that only CO, HCN, NNK, NH3, The seven most important harmful components including B[a]P, phenol and crotonaldehyde can represent the harmfulness of cigar...

Problems solved by technology

However, the mouth sticks made of activated carbon also have shortcomings, because the adsorption degree of activated carbon to these gas phase compounds is similar, and it does not show better HCN selective adsorption capacity, so activated carbon is also described as "total adsorbent".

In addition, a large number of research data show that the use of activated carbon added to the mouth stick will lead to a decline in the smoking quality of flue-cured cigarettes
