Description
Technical Field
The invention belongs to the technical field of tar and harm reduction of cigarettes, and particularly relates to a composite additive for reducing the release amount of phenol in smoke, a preparation method and application thereof.
Background
Smoking and health problems continue to be highly appreciated by the government, tobacco industry, and medical community. Tobacco contains a number of phenolic compounds, and currently identified phenolic compounds have been up to 280 or more [Baker RR,Massey ED,Smith G.An overview of the effects of tobacco ingredients on smoke chemistry andtoxicity[J].Food and Chemical Toxicology,2004,42:53-83], and are structurally classified into simple phenols and polyphenols. The simple phenol has strong volatility, enters a human body along with main stream smoke, and is a kind of harmful components needing to be focused in the main stream smoke of cigarettes. Wherein phenol has been listed by the Canadian government under 46 harmful components list and the WHO "tobacco products control research group" recommended control components list [Hoffmann D,Hoffmann I.The less harmfull cigarette:A controversial issue.A tribute to Ernst L.Wynder[J].Chemical Research in Toxicology,2001,14(7):761-791].
At present, the tobacco industry in China is actively advancing the harm-reducing and tar-reducing engineering, and phenol is also listed as a main harm-reducing object. A great deal of literature reports on a technical means for reducing phenol, mainly researches and develops a functional material of a filter tip, and selectively reduces harmful components in cigarette smoke. For example Xu Jianrong et al disclose the addition of glycin glycerides in cigarette filters to reduce the amount of phenol released in cigarette smoke [ use of amino acid glycerides to reduce the amount of phenol released in cigarette smoke, CN201610541856.9,20160712]. Xie Lanying et al discloses a forming paper composed of cellulose forming paper and a perfume-carrying substance doped polyvinylpyrrolidone micro-nano superfine fiber film layer on the surface of the cellulose forming paper, wherein the forming paper can selectively reduce the content of smoke phenol [ the superfine fiber functionalized cellulose forming paper with perfume-carrying and smoke phenol content selective reduction functions, and preparation and application thereof, CN201811324094.2,2018.11.08]. Wang Jin et al disclose a built-up additive (polyvinylpyrrolidone and vinylpyrrolidone-maleic acid copolymer) which can reduce the amount of released phenol in the smoke by adding to the filter tow [ a built-up additive and application for reducing the amount of released phenol in the smoke, CN201810237096.1,2018.03.21].
In the cigarette burning and smoking process, the time of smoke passing through the filter tip is very short, and meanwhile, the smoke of the cigarette is complex aerosol composed of thousands of components, and when the smoke passes through the filter tip, the adsorption effect of the disclosed functional material is influenced, so that the effect of reducing the release amount of phenol in the smoke is influenced.
The present invention has been made to solve the above problems.
