| Abstract: | In order to improve the utilization of tobacco stems,tobacco stem was treated by steam explosion at the pressure of 0.6,0.8,1.0 MPa,respectively lasting 20 s.The changes on cellulose and hemicellulose contents of the tobacco stem were studied as well as the microstructures.It indicated that cellulose and hemicellulose contents of tobacco stems decreased by 16.86% and 52.54%,respectively.It proved that steam explosion could degrade lignocellulose of tobacco stems and improved the quality of tobacco stems sig... |
