摘　　要：以魔芋葡甘聚糖(KGM)及其衍生物魔芋超强吸水剂(KSAP)为对象,考察在烟草薄片中的保润效果,并与甘油、丙二醇进行了对比。同时采用回归方程建立KSAP在烟草薄片中的保润模型。结果表明:KGM、KSAP的保润效果优于甘油和丙二醇,且KSAP的保润效果最好。烟草薄片的水分比率(MR)与KSAP浓度(c)和保润时间(t)的相关性模型为MR=exp[(0.0036Ln(c)-0.0199)t]。The effect of konjac glucomannan and its derivative konjac superabsorbent polymer on moisture retention of tobacco sheets were investigated by contrasting with glycerin and propylene glycol.The moisture retention model of KSAP in tobacco sheets was established by fitting regression analysis.It was found that the moisture retention effect of KGM, KSAP were better than those of glycerin and propylene glycol,and KSAP was the best.The equation of tobacco sheet moisture ratio with KSAP concentration and moisture retention time was MR = exp [ （0.0036Ln（c） -0.0199） t].
