Abstract: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 opti-mized 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 sen-sory 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 NaOH solution concentration,60 ℃ of reaction tem-perature,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.
