Super low free radical cigarette

Abstract

The cigarette with super low free radical content features its delayed released plant polyphenol microcapsule content of 0.02-0.6 wt% of shredded tobacco. The plant polyphenol microcapsule is first dissolved in water, alcohol, mixture of water and alcohol or water solution of propylene glycol and the solution is then sprayed to shredded tobacco. The delayed released plant polyphenol microcapsule may be catechin microcapsule, gallic acid microcapsule as degraded product of tannin or grape polyphenol microcapsule. The added plant polyphenol has stability raised by 9-12 times, extraneous antioxidant performance raised by 5-6 times and intracorporal antioxidant performance raised by about 10 times. Its effective component may be absorbed by oral cavity and respiratory system to eliminate free radical in body while meeting the need of smokers.

Description

Technical field: [0001] The patent of the present invention relates to tobacco products, that is, a cigarette with ultra-low free radicals. Background technique: [0002] Cigarette smoke contains hundreds of free radicals, which can directly damage cell membranes and biological macromolecules (such as proteins, nucleic acids), and can also cause the consumption of antioxidant enzymes (such as SOD enzymes, GSH-PX enzymes, CAT enzymes, etc.) in the human body , causing the disorder of the antioxidant enzyme system in the body and the reduction of enzyme activity, which is the main reason for the increase in the incidence of respiratory diseases, cardiovascular diseases, oral diseases and tumors caused by smoking. In addition, the free radicals produced by smoking and discharged into the ambient air have adverse effects on the health of passive smokers. At present, the main technology used to reduce free radicals in cigarettes is to add antioxidants in cigarettes, such as tea ...

AI Technical Summary

Problems solved by technology

However, the direct addition of antioxidants mainly has the following defects: ① poor stability and easy to be oxidized naturally; ② directly adding antioxidants to shredded tobacco, most of them are directly burned, which affects the smoking taste of cigarettes on the one hand, and reduces the antioxidant capacity on the other hand. Effective utilization of oxidants; ③In the technology of directly adding antioxidants to the chewing stick, there is insufficient contact between antioxidants and free radicals in the flue gas, which affects the removal effect, and the process cost is high, which increases by more than 300 yuan per large box , which is not conducive to the promotion of this technology; ④ No matter whether antioxidants are directly added to shredded tobacco or added to the stick, it is impossible to completely remove the free radicals in the smoke, and the remaining free radicals can still lead to increased free radicals in the body and Antioxidant enzyme system disorder, causing body damage

[0003] In recent years, studies have been conducted on adding common plant polyphenol microcapsules to shredded tobacco to reduce the bad breath (mainly H 2 S and mercapto compounds), but the availability of antioxidants is not high, and the microcapsules used do not have sustained-release characteristics (the sustained-release characteristics of microcapsules are determined by the type of microcapsule wall material, the molar ratio of wall film to capsule core material, and the formation of wall material. It depends on high temperature (600°C) to melt the wall to release plant polyphenols. Some plant polyphenols are oxidized at high temperature, so the effect on free radical scavenging in flue gas is limited.

[0004] Slow-release plant polyphenol microcapsules, that is, microcapsules that release plant polyphenols at 230-300°C, have been developed and produced by domestic scientific research institutions, but there are no reports of their application in cigarette production
