Cigarette tip for effectively scavenging radicals in cigarette smoke

Abstract

The present invention provides ciagarette filter tip capable of effectively removing free radical and reducing smoke toxicity, said filter tip two contains proanthocyanidin and said material at low concentration can effectively removing gaseous phase free radical in cigarette smoke. At the same time, when proanthocyanidin and vitamin C are mixed and used, it also possesses rather good eliminating action of gaseous phase free radical. The present invention also provides method of making said cigarette filter tip. Said filter tip can be produced in bulk and needs no large equipment investment.

Description

1. Technical Field [0001] The invention relates to a cigarette filter which can effectively remove gas-phase free radicals in cigarette smoke and a manufacturing method thereof. 2. Background technology [0002] It has been understood that a large number of gas phase and solid phase free radicals are produced when cigarettes are burned. After these substances are inhaled into the human body, they attack cells and cause toxicity and cause disease. Among them, gas phase free radicals are the most harmful substances. [0003] Epidemiological investigations have shown that smoking can not only cause bronchitis and lung damage, but also cause cancer and cardiovascular and cerebrovascular diseases with the highest mortality rate. Now the whole world has set off a campaign to boycott tobacco, and signs that smoking is not allowed can be seen everywhere in public places. People used to think that the toxicity of smoking comes from nicotine, but in fact it is not the only toxic substance....

AI Technical Summary

Problems solved by technology

But these two technologies have not been applied and promoted by the majority of tobacco companies

Mainly because there are two problems: 1. Compared with ordinary filters, the doses of additives in these two filters are relatively large, which makes the smoke smell like cigarette smoke after passing through this filter. If it is changed, it will destroy the consumer's suction experience, so it will not be recognized and accepted by consumers; 2. Since these two types of filters are composite filters, manufacturing such filters requires huge equipment transformation investment, which is unacceptable for general tobacco companies

Therefore, tobacco factories dare not blindly produce cigarettes using this technology, which is also the main reason why low-toxic and low-free radical cigarettes could not be promoted and used to reduce the toxicity of cigarettes to smokers.
