Abstract:This paper studied beating performance, sheet forming performance of tobacco stem(a kind of reconstituted tobacco raw material)which was extracted with water, ethanol water solution and alkaline ionic liquid ［MMIM］DMP and the smoking performance of the reconstituted tobacco sheet. The results showed that the removal rate of lignin in tobacco stems extracted by ［MMIM］DMP was the highest, which was about 5 times of that extracted by water and even much higher than ethanol aqueous solution. Compared with the water and ethanol aqueous solution, the beating and sheet forming performances of tobacco stem extracted with ［MMIM］DMP were upgraded significantly the tensile strength and bulk as well as permeability of the treated sheet were improved. After the massive delignification in tobacco stem extracted by ［MMIM］DMP, the contents of the smoke compositions and the scores of the sensory quality index were optimized, and the smoking performance was improved obviously, which improved the quality of the reconstituted tobacco product.
