  • 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 NaOH 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 difference was not obvious; 3) CM-GLP possesses the roles of making cigarette smoke mellow and full, reducing irritation and elevating comfortable mouthfeel.
