Problems solved by technology

Scholars at home and abroad have also done a lot of research in this regard, such as using tea polyphenols, pycnogenol, apocynum and other substances to be adsorbed by activated carbon to make a composite filter to remove free radicals, or to add Chinese herbal medicine ingredients to shredded tobacco to remove free radicals. Free radicals, such as the patent of invention published by the Chinese Patent Application No. 95116865.7, using apocynum to add in shredded tobacco can reduce cigarette free radicals by 11.5%. Tea polyphenols and vitamin C are mixed in equal proportions and added to activated carbon to make a composite filter. Mouth can reduce cigarette free radicals by 23.5%, and the processing technology is relatively complicated

specific Embodiment 1

[0016] 1. Dissolve tea polyphenols (95% purity) with 70% alcohol to make the proportion of tea polyphenols reach 10%;

[0017] 2. Compound the above solution with a mouth stick forming agent (glycerol triacetate) to form a mouth stick forming agent containing 4% tea polyphenols;

[0018] 3. Utilize the above-mentioned mouth stick forming agent to produce biological filter in filter forming machine;

[0019] 4. After the above-mentioned filter tip is attached to a cigarette, the free radical scavenging rate reaches 11.3% through a comparison test.

specific Embodiment 2

[0020] 1. Dissolve ginkgo ketone (24% purity) with 60% alcohol to make the ratio of ginkgo ketone reach 20%;

[0021] 2. Compounding 5% ginkgo ketone solution and glycerol triacetate to form a mouth stick forming agent containing 8% ginkgo ketone;

[0022] 3. Utilize the above-mentioned tip forming agent to produce filter tips in a filter forming machine;

[0023] 4. After the above-mentioned filter tip is attached to a cigarette, the free radical scavenging rate reaches 8.9% through a comparative test.

specific Embodiment 3

[0024] 1. Mix ginkgo ketone (24% purity), tea polyphenols (95% purity), and tanshinone in a ratio of 1:1:1, and dissolve them in 70% alcohol, so that the ratio of the three in the solvent reaches 30%;

Abstract

The biological harm reducing cigarette filter tip of the present invention features that the forming agent in the cigarette filter tip contains free radical eliminating agent ginkgetin, tea polyphenol, tanshinone or their combination in 0.1-10 wt%. Experiment shows that the filter tip of the present invention can eliminate free radical in cigarette with the eliminating rate as high as 25 %. The present invention can raise the safety of smoking and increase the content of health care components in smoke. Compared with other measures, the present invention has the advantages of easy industrial realization and low cost.

Description

Technical field: [0001] The invention relates to a cigarette filter in the field of tobacco, in particular to a biological harm reduction cigarette filter. Background technique: [0002] Smoking and health problems have become one of the key research contents of the tobacco industry, and scientists from all over the world are trying to find ways to reduce the harm of cigarettes. At present, various attempts are mainly focused on the use of cigarette filter technology, through the use of cellulose acetate or activated carbon composite filters to enhance the interception efficiency, to achieve the purpose of removing harmful components in cigarettes, and some components such as apocynum are directly added to shredded tobacco To achieve focus reduction and harm reduction. Free radicals are defined in chemistry as atoms or atomic groups containing at least one unpaired electron. Recent studies have shown that free radicals are one of the most harmful products in cigarettes. Uns...
