摘　　要：以灵芝为原料提取灵芝多糖GLP,并制备了其羧甲基化产物(CM-GLP),以羧甲基化取代度为指标,采用正交试验对灵芝多糖羧甲基化修饰条件进行优化.以空白烟丝为对照,以烟丝含水率为指标对CM-GLP,GLP,丙二醇和甘油的物理保润性能进行测试,并以感官舒适度验证其在卷烟中的应用效果.结果表明:1)羧甲基化的最佳工艺条件为氯乙酸用量85 g,Na OH溶液浓度4.5 mol/L,反应温度60℃,反应时间2 h,在此条件下取代度均值为1.36;2)在低湿条件下,CM-GLP的保湿性能优于丙二醇和甘油,GLP的保湿性能略差于丙二醇,在高湿条件下,四者差异不明显;3)CM-GLP可使卷烟烟气柔和、圆润,减少刺激性,具有提升感官舒适性的作用.Using Ganoderma as raw material,one kind of Ganoderma lucidem polysaccharide（ abbreviated GLP） was extracted and the carboxymethyl product（ CM-GLP） was prepared. Using the carboxymethylated degree of substitution（ DS） as an indicator,the carboxymethyl modification conditions of GLP were optimized by using the orthogonal test. Using blank tobacco shred as control and the moisture content of tobacco shred as an indicator,the physical moisture retention properties of CM-GLP,GLP,propylene glycol（ PG）and glycerol were measured,and the effects of these two samples and two traditional humectants on the sensory comfort levels in cigarettes were investigated. The results showed that： 1） the optimum technological condition was 85 g of chloroacetic acid,4. 5 mol / L of Na OH solution concentration,60 ℃ of reaction temperature,and 2 h of reaction time,and the mean value of DS under this condition was 1. 36; 2） under low humidity conditions the moisture retention property of CM-GLP was superior to PG and glycerol,and the moisture retention property of GLP was slightly worse than PG,under high humidity conditions,four differ-ence was not obvious; 3） CM-GLP possesses the roles of making cigarette smoke mellow and full,reducing irritation and elevating comfortable mouthfeel.
