不同润叶模式对初烤烟叶化学成分的影响

Effects of Different Moistening Modes on Chemical Components of Flue-cured Tobacco

【目的】探索不同等级烟叶原料的适宜打叶复烤润叶模式,为卷烟品牌核心原料差异化润叶加工提供技术依据。【方法】以红河弥勒K326中桔一(C1F)和曲靖红花大金元上桔一(B1F)2种初烤烟叶为材料,在二级润叶模式(蒸汽+湿热风)保持不变的情况下,一级润叶模式设置蒸汽+水、干热风+水、蒸汽+湿热风+水、蒸汽+干热风+水共4种处理,分析不同润叶模式下烟叶常规化学指标、挥发性致香物质、淀粉、果胶、石油醚提取物、总多酚、质体色素含量和化学成分可用性指数(chemical components usability index,CCUI)的差异。【结果】(1)不同润叶模式下,同一烟叶原料的出料温度及多项化学成分含量存在较大差异。(2)K326 C1F初烤烟叶一级润叶适宜采用蒸汽+湿热风+水的润叶模式,红花大金元B1F初烤烟叶一级润叶适宜采用蒸汽+干热风+水的润叶模式。【结论】不同润叶模式对相同烟叶原料化学成分的影响较大,且不同烟叶原料适宜采用不同润叶模式。本研究为不同烟叶原料的差异化润叶加工提供了技术依据。

[Purpose]To explore suitable moistening modes for flue-cured tobacco leaves of different grades,providing a technical basis for differential moistening of core raw materials for cigarette brands.[Methods]Two kinds of flue-cured tobacco leaves(Honghe Mile K326 C1F and Qujing Honghuadajinyuan B1F)were selected as test materials.Under the condition that the secondary moistening mode(steam+damp hot wind)remains unchanged,four primary moistening modes were set as follows:steam+water,dry hot wind+water,steam+damp hot wind+water,and steam+dry hot wind+water.The differences in routine chemical indexes,volatile aromatic components,starch,pectin,petroleum ether extract,total polyphenols,plastid pigments,and the chemical components usability index(CCUI)of tobacco leaves under different moistening modes were analyzed.[Results]1)There were obvious differences in the outlet temperature and the contents of many chemical components in the same flue-cured tobacco under different moistening modes.2)The primary moistening of K326 C1F flue-cured tobacco was more suitable for the steam+damp hot wind+water mode,while the primary moistening of Honghuadajinyuan B1F flue-cured tobacco was more suitable for the steam+dry hot wind+water mode.[Conclusion]Different moistening modes have varied effects on the chemical components of the same tobacco raw materials,and different moistening modes are suitable for different tobacco raw materials.This study provides a technical basis for the differential moistening mode of different tobacco materials.
