Abstract
The invention provides a method for reducing polyphenol content in paper-making process sheet tobacco extract liquid. The method for reducing the polyphenol content in the paper-making process sheet tobacco extract liquid comprises the following steps of 1 adding an absorbent into the tobacco extract liquid, and 2 removing the absorbent centrifugally, wherein the adding amount of the absorbent is 0.1-10% of the mass of the tobacco extract liquid. By means of the technical scheme, the chlorogenic acid, rutin and scopoletin content in the tobacco extract liquid can be effectively reduced, improvement of smoking quality of tobacco is facilitated with reduction of the polyphenol content, and offensive odor and stimulating problems of cigarettes are well solved.
Description
Technical field
The invention belongs to papermaking-method reconstituted tobaccos field, be specifically related to a kind of method reducing polyphenol content in papermaking-method reconstituted tobaccos extract.
Background technology
Chlorogenic acid, rutin sophorin and scopoletin are topmost polyphenols in tobacco.Its Content of Chlorogenic Acid accounts for the 75%-90% of total polyphenols.Containing the chlorogenic acid of 3% or higher, the rutin sophorin of about 1% and a small amount of scopoletin in flue-cured tobacco.Polyphenol in tobacco is the main producers of simple phenols in flue gas.A large amount of aldehydes matters is created during chlorogenic acid pyrolysis, comprising: the cigarette smoke harmful substances such as phenol, catechol, resorcinol, hydroquinones.Also the cigarette smoke such as phenol and catechol harmful substance is created during rutin sophorin pyrolysis.The cigarette smoke harmful substances such as a small amount of phenol, resorcinol, hydroquinones are then created during scopoletin pyrolysis.Evidence suggests that the existence of aldehydes matter can significantly improve the carcinogenic activity of polycyclic aromatic hydrocarbon.In cigarette mainstream flue gas, the number of the content of aldehydes matter directly has influence on the security of cigarette.Some aldehydes matter may be the mouthfeel affecting cigarette in addition, causes the sordid a kind of factor of astringent taste, pungent, pleasant impression.Therefore, polyphenol content in reconstituted tobacco extract is reduced extremely important for the quality improving reconstituted tobacco.
