摘　　要：以添加蒸馏水和丙二醇的烟丝为对照,比较具有代表性的微生物多糖和海藻多糖在烟丝中的热力学保润效果,并选取3种常见的烟丝动力学模型对烟丝的吸湿和解吸过程进行拟合。结果表明,海带多糖及螺旋藻多糖的保润效果优于丙二醇;Page模型拟合效果最好。根据保润指数综合考虑热力学与动力学因素,螺旋藻多糖、海带多糖和猴头菇多糖具有较优的保润效果。低场核磁表明,与添加蒸馏水和丙二醇的烟丝相比,添加3种较优保润剂的烟丝化学结合水含量大幅增加,烟丝中的水分更不易失去。Thermodynamic moisture retention properties of microbial polysaccharides and seaweed polysaccharides were investigated as compared with water and propylene glycol.Then three common dynamic models of tobacco were selected to fit the hygroscopic and desorption processes of tobacco.The results showed that the moisture retention of Laminaria japonica polysaccharides and Spirulina platensis polysaccharides was significantly better than that of propylene glycol,and page model was the best.Considering the thermodynamic and kinetic factors according to the moisturizing index,Laminaria japonica,Spirulina platensis and Hericium erinaceus polysaccharides were considered to have better moisturizing effect.Low field nuclear magnetic results showed that the addition of aforementioned three polysaccharides increased the chemically bound water content in tobacco as compared with the addition of water and propylene glycol,thus the moisture in the tobacco is less likely to be lost.
