Effects of Different Processing Modes of Reconstituted Tobacco on Cigarette Quality

再造烟叶不同加工方式对卷烟品质的影响（英文）

In order to explore the most suitable mode for the primary processing model of reconstituted tobacco, another two kinds of conditioning process schemes for reconstituted tobacco were designed based on the existing reconstituted tobacco processing method. Comparative analysis and evaluation were conducted for moisture content uniformity, intrinsic chemical compositions, casing uniformity, blending uniformity and sensory quality of the samples from the three kind of processing modes. The results showed that loosing and conditioning or the vacuum conditioning pretreatment of the reconstituted tobacco could effectively reduce the difference in moisture content during the blending, and improve the casing uniformity and blending uniformity. Moreover, the samples with the loosing and conditioning pretreatment had higher total sugar and reducing sugar contents, which indicated that the loosing and conditioning pretreatment method was more favorable for the improvement of the intrinsic quality of cigarettes. In addition, the three kinds of aromatic components contents of cigarettes using the loosing and conditioning pretreatment were higher,and the casing uniformity, blending uniformity and overall sensory quality of this pretreatment were all superior to that of the other two kinds of reconstituted tobacco pretreatment methods. The contents of total sugar, reducing sugar as well as the three kinds of aromatic components of cigarettes processed with vacuum conditioning pretreatment were all slightly lower than those of the existing methods, but the casing uniformity and blending uniformity were improved, while it showed small difference in the sensory quality with the existing processing method.

为探索更适宜再造烟叶的制丝加工工艺模式,在现有再造烟叶加工方式的基础上,设计了另外两种再造烟叶回潮预处理加工方案,并对3种加工方式样品的含水率一致性、内在化学成分、加料均匀性、掺配均匀性和感官质量进行了比较分析和评价。结果表明:再造烟叶松散回潮或真空回潮预处理加工方式,掺配时可有效降低与片烟的含水率差异,提高后端的加料均匀性和掺配均匀性。其中,松散回潮预处理加工方式卷烟的总糖和还原糖含量较高,表明该加工方式更有利于卷烟内在品质的提升。此外,松散回潮预处理加工方式卷烟的三类致香物质含量均较高,且加料均匀性、掺配均匀性和整体感官质量优于其他两种再造烟叶加工方式。再造烟叶真空回潮预处理加工方式卷烟的总糖、还原糖及三类致香物质总量略低于现有加工方式,加料均匀性和掺配均匀性有所提高,整体感官质量与现有加工方式差异较小。
