The edible wax, AJ polysaccharide monomer and recombination samples were selected for the moisture retention test to evaluate the moisturizing property of tobacco in low humidity environment. The results showed that the edible wax and AJ polysaccharide monomer both had certain effect on the moisture of tobacco. The moisturizing property of plant wax 1 was better than that of other edible wax. When the edible wax and AJ polysaccharide monomer were compounded, the moisturizing performance of the tobacco was further improved by the coordination effect of the two samples. Scanning electron microscopy (SEM) revealed that besides the effect of traditional humectant, the edible wax-polysaccharide recombination humectant could change the surface structure of the tobacco and form a compact protective film on the surface of the tobacco leaf, while filling and blocking the tobacco surface and cut surface. Thus increasing the mass transfer resistance of water inside and outside the tobacco, confirmed the moisturizing effect and principle of action of edible wax-polysaccharide recombination humectant. The sensory evaluation results showed that edible wax-polysaccharide recombination humectant was applied to cigarette to increase cigarette comfort performance, reduce smoke irritation, and the quality of smoking was better than that of controlled cigarette.
