摘　　要：为改善再造梗丝产品香气平淡、杂气较多的问题,对其原有制备工艺进行优化调整,具体为以组合酶萃取代替温水萃取,辅以组氨酸Heyns化合物(His-H)进行回填加香,并采用核磁共振波谱(NMR)技术、气相色谱-质谱联用法等对工艺调整前后再造梗丝中试产品常规化学成分、细胞壁主要组分和感官品质的变化进行探讨。结果表明:萃取时使用的最优溶液应为质量分数0.8%E_(c)和质量分数0.4%E_(p)的组合酶溶液,萃取后产品质软色浅;回填阶段添加质量分数0.25%的His-H后,再造梗丝香气质提升,杂气减少,刺激性下降,感官品质整体优于对照梗丝;工艺调整后再造梗丝中试产品的常规化学成分保持协调,中性香气物质总含量提升约27.0%,细胞壁主要组分(纤维素、果胶和木质素)含量降低率超过15.0%,所制卷烟烟气透发性优于对照品,木质气下降,香气量明显增加,吸食品质明显提升。To address the issues of high cell wall content and inadequate aroma in the reconstruction tobacco stem(RTS)products,the original preparation process was optimized and adjusted.Specifically,a combination of enzyme extraction replaced warm water extraction,supplemented with histidine Heyns compound(His-H)for backfilling and flavoring.The contents of cell wall materials and neutral flavor substances of RTS products were analyzed by NMR technology and GC/MS,respectively.The effects of new preparation process of RTS on the quality of last products were evaluated through sensory evaluation in RTS cigarettes.The results showed that the optimal enzyme extraction concentration was complex enzyme solution(0.8%E_(c)+0.4%E_(p))and the product was getting“soft”and“faded”after extraction.With the addition of 0.25% histidine Heyns compound during the back-filling stage the sensory quality of RTS product was better than that of the control RTS with less off-flavors and irritation.After process adjustment,the conventional chemical composition of two new reconstructed products remains coordinated.The contents of neutral flavor substances were increased by 27.0% and the contents of cell wall materials of them were all decreased above 15.0%.The aroma volume of the new product increased significantly after process adjustment,which was better than the control product in terms of the permeability of the smoke,and therefore could significantly reduce the wood gas and improve the smoking quality.
