摘　　要：卷烟烟气中的含水率直接影响卷烟评吸的感官舒适度,而卷烟在贮藏过程中其含水率极易受到环境影响。为了提高卷烟烟丝中的水分稳定性,亟待开发在高湿、低湿环境中均有效的双向阻水添加剂。通过对脂肪烃类物质和多糖类物质的复配添加,利用两者的协同效应,可以达到良好的保润目的。通过在35℃下模拟高湿、低湿环境,对烟丝进行加速贮藏试验,证明脂肪烃类和多糖类化合物均对烟丝的双向阻水有一定效果,当类脂GY/多糖B按烟丝总重量的(1.0%/0.1%)复配添加时能达到很好的协同作用。通过环境扫描电镜(ESEM)观测,发现烟丝表面阻湿剂涂层结构能有效减少烟丝暴露在环境中的表面积,可以证明双向阻湿剂的效果及其作用原理。The water content of mainstream smoke components is closely associated with the sensory comfort of smoking, and it was also susceptible to the environment. In order to improve the stability of the water content in cigarette tobacco, the effective two-way wa- ter-blocking additive was developed of aliphatic hydrocarbons and compound sugars, the synergy of both additives made the water con tent of tobacco under a good control. The function of the additive was proved by testing in the simulation environment （RH=32% and RH=84%） in 35 ℃. Finally, proved that when added 1. 0% all phatic hydrocarbon （GY） and 0. 1% polysaccharose （B）, a good two-way water blocking effect can be achieved, effectively delaying either the tobacco moisture absorption or desorption time. Through using the environmental scanning electron microscopy （ESEM）, studied the surface of the tobacco and found the coating material iso- lating the tobacco from the environment, which would be a convinc-ing evidence to show the additive does work.
