为了解烟丝组织结构与保润性能的关系,应用扫描电子显微镜(SEM)观察了烤烟、白肋烟、香料烟3种烟丝表面和切面结构,光学显微镜观察烟丝下表皮气孔,比表面积测试仪测定烟丝毛细管比表面积大小.结果表明:①香料烟结构最为紧密,切面含有很多空隙结构,国产烤烟和津巴布韦烤烟的切面较疏松.②白肋烟气孔数目在烤烟与香料烟之间,同一品种烤烟不同部位烟丝样品比表面积大小:中部>下部>上部.③低湿度(RH=30%)环境条件下烟丝组织结构与平衡含水率正相关;高湿度(RH=60%)环境条件下,烟丝组织结构与平衡含水率负相关,随着相对湿度的增加,烟丝表面化学成分对含水率的影响程度逐渐加强.

To Study the relationship between tissue structure of cut shreds and moisture retentivity thereof, the surface and sectional structures of flue-cured, burley and oriental tobacco shreds were observed by a scanning electron microscope, the stomas of under epidermis were observed by an optical microscope, and the capillary specific surface area was measured by a specific surface area tester. The results showed that:1) The structure of oriental tobacco was the closest and its section was of porous structure, the section of domestic and Zimbabwean flue-cured tobacco was opener. 2) The stoma number of burley tobacco was higher than that of flue-cured tobacco, while lower than that of oriental tobacco. The stalk positions of flue-cured tobacco of the same variety in the order of specific surface area were middle > lower > upper. 3) The tissue structure positively correlated to equilibrium moisture content of tobacco shreds in low humidity (RH=30%) environment, while their correlation became negative in high humidity environment (RH=60%); and the influence of surface chemical composition in tobacco shreds on moisture content increased gradually with the rise of relative humidity.
