Abstract: In order to investigate the effect of moisture content in cigarette smoke on sensory coziness, glycerol was added to cut tobacco to regulate smoke moisture content, the sensory quality of experimental samples was evaluated, the relation between sensory coziness and moisture content in smoke was analyzed by pattern recognition.The results showed that:1) sensory coziness was greatly affected by moisture content in smoke, the appropriate moisture content ranged from 3.77% to 4.58%, and the corresponding glycerol addition rate was from 0.50% to 2.00%;2) the moisture content in cigarette smoke could be regulated by adding glycerol, while sensory coziness would be negatively affected when glycerol addition rate was over 3.00%.Therefore, controlling moisture content in smoke in cigarette design can improve sensory quality, and glycerol is an additive that can increase moisture content in smoke.
