摘要:利用蒸汽爆破技术对烟梗进行预处理,研究不同水蒸汽压力条件下烟梗的微观结构、化学成分以及抄造的烟草基片的物理性能和烟叶的感官品质,结果表明:蒸汽爆破压力对烟梗结构及烟草基片物理性能影响较大,随着蒸汽压力的增加,烟梗结构膨胀,空洞间隙扩大增多,磨浆后烟梗浆打浆度增加,烟草基片的抗张强度、柔软度和匀度提升明显,但对松厚度影响较小。当蒸汽压力为0.6 MPa时烟梗结构破坏不明显,总糖含量增加达到最大值,能够显著改善再造烟叶感官质量。适当的蒸汽爆破处理烟梗能显著改善烟草基片物理性能和再造烟叶感官质量,工业应用时蒸汽爆破压力应低于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 tobacco substrate and the organoleptic quality of reconstituted tobaccos under different water vapor pressure conditions were studied. The results showed that the steam explosion pressure exerts a considerable influence on the structure of tobacco stems and the physical properties of tobacco substrate. As the steam pressure rises, the structure of tobacco stems expands, the void and gap spaces enlarge and increase. After pulping, the beating degree of tobacco stem pulp increases. The tensile strength, flexibility and uniformity of the tobacco substrate are enhanced significantly, but it has a relatively small effect on the bulkiness. When the steam pressure was 0.6 MPa, the structural damage of tobacco stem was not obvious, and the total sugar content increased to the maximum, which could significantly improve the organoleptic quality of reconstituted tobaccos. Proper steam blasting treatment of tobacco stems can significantly improve the physical properties of tobacco substrates and organoleptic quality of reconstituted tobaccos, and the steam blasting pressure should be lower than 0.6 MPa in industrial application.
