Composite filter tip containing biological composition

Abstract

The invention relates to a composite filter tip containing a biological composition. A filament bundle filter stick of the filter tip comprises the biological composition, and after the biological composition is stuck to a carrier, when the filament bundle filter stick is formed, the carrier to which the biological composition is stuck is added into the filament bundle filter stick, wherein the biological composition comprises cobalt porphyrin and ginkgo leaf extract with the mass ratio being 1:1-80. The filter tip can not only obviously reduce the release amounts of harmful ingredients such as free radical, benzo[a]pyrene, peculiar nitrosamines of tobacco, and the like in smoke of cigarettes but also can enable the acute toxicity, subchronic toxicity, cytotoxicity and mutagenicity of the cigarettes to be lower as compared with comparison cigarettes, and at the same time has no adverse effects on the smoking quality of the cigarettes.

Description

technical field [0001] The invention relates to a composite filter containing a biological composition, in particular to the application of the biological composition formed of cobalt porphyrin and ginkgo biloba extract in a cigarette filter, which belongs to the cigarette filter additive and filter processing technology. Background technique [0002] Cigarette filters are used to filter harmful substances in cigarette smoke, and the interception rate of tar is about 35%. Existing fiber filter rods are mainly made of acetate fiber tow or polypropylene fiber tow, and their filtering effect depends on their molecular structure and physical and chemical properties. Due to the limitations of its structure and physical and chemical properties, there are deficiencies in terms of filtering effect. The cellulose acetate tow filter material has a negative charge, and many particles in cigarette smoke also have a negative charge. There are about 2×10 in the flue gas 9 Due to the rep...

AI Technical Summary

Problems solved by technology

Its hydrophobic group is a non-polar structure, and there is no polar structure with high affinity with polar smoke components. The change of pressure drop does not affect the selective filtration of the polar components of the smoke, so it has no effect on the polar components in the smoke. The interception rate of substance molecules is low, and the interception performance of the molecules of pungent and irritating impurities with low boiling point in cigarette smoke is poor

[0003] As we all know, cigarette smoke contains a variety of harmful components, especially free radicals that may cause cancer, condensed aromatic hydrocarbons, tobacco-specific nitrosamines, etc., and the above-mentioned traditional cigarette filters cannot effectively filter out these substances
