| Abstract: | Objective To improve the quality of reconstituted tobacco sheet, it is of great importance to reduce the lignin content of the tobacco stem and to enhance the smoke agent load at the same time. Methods Smashed tobacco stem was treated with different concentrations of smoke agents (propylene glycol and glycerol). The fresh and treated tobacco stem samples were characterized by GC-FID, FTIR, TG and SEM. The lignin content of the tobacco stem samples before and after the reaction was determined by Klason method. Result the lignin content was reduced by 33%~37% after the treatment. The loading capacity of propylene glycol and glycerol in the samples ranged from 0.52% to 2.57% and 24.84% to 54.10%, respectively. The loading capacity of glycerol in tobacco stem could be significantly improved enhanced due to the presence of propyl glycol Conclusion The method significantly reduced the lignin content and improved the loading capacity of smoking agent in the tobacco stem at the same time, which can be applied as a promising technology for production of heated tobacco products. |
