Method for effectively improving quality of reconstituted tobaccos

Abstract

The invention discloses a method for effectively improving the quality of reconstituted tobaccos. A tobacco raw material extracting solution is firstly filtered through a tubular microfiltration membrane, wherein the filtration pore diameter of the tubular microfiltration membrane is 100-500 nm; filtrate is filtered through a nanofiltration membrane, wherein the pore diameter of the nanofiltrationmembrane is 1-2 nm; and filtrate is obtained. According to the method, the tobacco raw material extracting solution used in the coating process is filtered through the tubular microfiltration membrane, so that suspended matter impurities in the extracting solution can be effectively removed, the sensory smoking quality of the finished reconstituted tobaccos is improved, the smoke clearness of reconstituted products is improved, and impurity gas of the reconstituted tobacco products is reduced; chloride ions and nitrate ions in tobacco raw materials can be effectively rejected by the nanofiltration membrane, so that the combustibility of the finished reconstituted tobaccos is improved, the taste quality of the reconstituted tobacco products is improved, and the content of strong carcinogenic tobacco-specific nitrosamine precursors is effectively reduced; and the method meets the requirements of reconstituted tobacco coating, and effectively retains aroma components and volatile components in the tobacco raw material extracting solution.

Description

technical field [0001] The invention relates to a method for improving the quality of tobacco leaves, in particular to a method for effectively improving the quality of reconstituted tobacco leaves, and belongs to the technical field of reconstituted tobacco leaves. Background technique [0002] Reconstituted tobacco leaves have incomparable advantages over natural tobacco leaves in terms of harm reduction, tar reduction, and regulation of the chemical components of cigarettes. It is currently the focus of research and attention in the tobacco industry at home and abroad. During the processing of the reconstituted tobacco leaves, the coating solution needs to be coated on the sheet base through a coating process. Although the sensory smoking quality of the reconstituted tobacco leaf products processed by the coating process will be improved, the reconstituted tobacco leaf products made by the prior art still have the problems of high miscellaneous gas, poor definition and po...

AI Technical Summary

Problems solved by technology

Although the sensory smoking quality of the reconstituted tobacco leaf products processed by the coating process will be improved, the reconstituted tobacco leaf products made by the prior art still have the problems of high miscellaneous gas, poor definition and poor taste quality, and some It has the disadvantage of poor combustibility, which leads to poor sensory smoking quality, and the content of tobacco-specific nitrosamine precursors in the reconstituted tobacco products of the prior art is high, and the risk of carcinogenicity is high
