摘　　要：利用动态水分吸附分析系统对不同烟草原料(上中下部叶丝、膨胀烟丝和膨胀梗丝)进行了等温吸湿-解湿行为的研究。结果表明:①烟丝的等温吸湿-解湿曲线呈III型吸附曲线,解湿时伴有较明显的滞后现象;②不同部位叶丝的等温吸湿-解湿性质基本一致;③叶丝、膨胀烟丝和膨胀梗丝之间的等温吸湿-解湿差别很大:当相对湿度不小于60%时,膨胀梗丝吸水最多,叶丝其次,膨胀烟丝最少;当相对湿度不大于40%时,膨胀梗丝失水最多,膨胀烟丝其次,叶丝失水最少。The isothermal sorption and desorption behavior of various tobacco materials, including cut rags of upper, middle and lower leaves, expanded tobacco and expanded stem, was studied by dynamic moisture sorption analyzer. The results showed that： 1） The isothermal sorption and desorption curves assumed the form of adsorption curve type III and obvious time lag was found in a desorption process; 2） The isothermal sorption and desorption behavior of cut rags of upper, middle and lower leaves was basically the same; 3） The isothermal sorption and desorption behavior of cut rags of strips, expanded tobacco and expanded stem differed significantly. At the relative humidity of ≥ 60%, expanded stem absorbed more moisture, and expanded tobacco absorbed less. While at the relative humidity of ≤ 40%, expanded stem lost more moisture, but cut tobacco lost less.
