为了提高烟梗的利用率,在梗丝生产线的不同工序顺序取样进行蒸汽爆破试验,研究了爆破前后各工序梗丝中的木质素、纤维素含量变化及添加爆破梗丝对卷烟的感官品质影响.结果表明:①原梗丝生产线对烟梗中的纤维素、半纤维素和木质素含量无显著影响,但蒸汽爆破后烟梗中的纤维素、半纤维素和木质素含量显著降低.半纤维素的含量降低最多,切梗后含量降低了49.5％.纤维素和木质素的含量变化没有半纤维素明显,但其最大降幅也分别达到了26.5％(润梗后)和26.0％(闪蒸后).②蒸汽爆破梗丝在卷烟中的添加量从5％增加到30％时,试验卷烟样品仍保持较好的感官品质.%In order to improve the utilization of tobacco stem, steam blasting experiment was conducted by sampling at each step in cut stem processing. The changes of lignocellulose content in cut stem before and after blasting were compared, and the effects of steam-blasted stem inclusion on the sensory quality of cigarette were investigated. The results showed that: 1) the original cut stem processing line had no obvious effect on the contents of cellulose, hemicellulose and lignin in stem, while which were significantly reduced by steam blasting. Particularly, the hemicelluloses, which reduced by 49.5% after stem cutting. The contents of cellulose and lignin decreased by 26.5% (after stem moistening) and 26.0% (after flashing steaming), respectively. 2) The sensory quality of cigarette samples was maintained pretty well when the addition rate of steam-blasted cut stem increased from 5% to 30%.
