| 摘要:本研究利用高温蒸汽对烟梗进行预处理，系统考察了蒸汽预处理时间对烟梗提取效率、提取液水溶性糖含量、微观结构及所制烟草薄片烟气释放特性的影响。结果表明，蒸汽预处理时间显著影响烟梗的提取率及提取液中糖类物质含量；相较于未处理烟梗（提取率为34.1%），蒸汽预处理8 min后（提取率为41.3%）提取率增幅达21%；同时，提取液中水溶性总糖和还原糖含量增幅均超过69%；微观结构分析显示，蒸汽预处理会导致烟梗组织结构膨胀、孔洞尺寸增大；烟气成分分析表明，蒸汽预处理能有效降低烟草薄片烟气中尼古丁、甲醛、甲醇、糠醛、氯甲烷等有害成分的含量，并能显著增加酸类、醛类、酚类等香气成分的含量。 |
| Abstract:In this study， high-temperature steam was used to pretreat tobacco stems， and the effects of steam pretreatment time on the extraction efficiency of tobacco stems， water-soluble sugar content in the extract， microstructure， and smoke release characteristics of the produced reconstituted tobacco sheets were systematically investigated. The results showed that the steam pretreatment time significantly influenced the extraction rate of tobacco stems and the sugar content in the extract. Compared to untreated tobacco stems (with an extraction rate of 34.1%)， the extraction rate increased by 21% after 8 min of steam pretreatment (with an extraction rate of 41.3%). Meanwhile， the increases in the content of water-soluble total sugars and reducing sugars in the extract both exceeded 69%. Microstructural analysis revealed that steam pretreatment caused the tissue structure of tobacco stems to expand and the pore sizes to increase. Smoke component analysis demonstrated that steam pretreatment effectively reduced the content of harmful components such as nicotine， formaldehyde， methanol， furfural， and chloromethane in the smoke of reconstituted tobacco sheets， and significantly increased the content of aromatic components such as acids， aldehydes， and phenols. |
