摘要:利用蒸汽爆破技术对烟梗进行预处理，研究不同蒸汽爆破预处理条件下烟梗的微观结构、化学成分以及抄造基片的物理性能和感官品质。结果表明，蒸汽爆破维压压力对烟梗微观结构及烟草薄片基片物理性能影响较大，随着蒸汽爆破维压压力的增加，烟梗的微观结构膨胀，空洞间隙扩大增多，磨浆后烟梗浆打浆度增加，相比于未处理样品，烟草薄片基片的抗张指数最高可提升至1.65倍，匀度提升60%，柔软度提升22%，但对松厚度影响较小。当蒸汽爆破维压压力为0.6 MPa时，烟梗微观结构破坏不明显，水溶性总糖含量相比原料提升11.6%，能够显著改善烟草薄片感官质量。适当的蒸汽爆破处理烟梗能显著改善基片物理性能和烟草薄片感官质量，工业应用时蒸汽爆破维压压力应低于0.6 MPa。

Abstract:Steam blasting technology was used to pretreat tobacco stems， and the microstructure and chemical composition of tobacco stems， as well as the physical properties of the reconstituted tobacco base sheets and the organoleptic quality of reconstituted tobacco sheets under different steam blasting pretreatment conditions were studied. The results showed that the maintained steam blasting pressure exerted considerable effects on the microstructure of tobacco stems and the physical properties of the reconstituted tobacco sheets. As the maintained steam blasting pressure rising， the microstructure of tobacco stems expanded， the void and gap spaces enlarged and increased. After beating， the beating degree of tobacco stem pulp increased， compared with untreated sample， the tensile index of the reconstituted tobacco base sheets could be increased by up to 1.65 times， the uniformity was increased by 60%， and the softness was increased by 22%， but it had a relatively small effect on bulk. When the maintained steam blasting pressure was 0.6 MPa， the microstructural damage of the tobacco stem was not obvious， and the water-soluble total sugar content was increased by 11.6% compared with that of the raw material， which could significantly improve the organoleptic quality of the reconstituted tobacco sheets. Appropriate steam blasting treatment of tobacco stems could significantly improve the physical properties of the reconstituted tobacco base sheets and organoleptic quality of reconstituted tobacco sheets， and the maintained steam blasting pressure should be lower than 0.6 MPa in industrial application.
