摘要
【目的】探讨打叶复烤生产工艺对上部烟叶常规化学成分的动态影响规律,为优化复烤工艺参数以提升上部烟叶品质提供理论依据。【方法】以云产品牌黄金叶上部烟叶为研究材料,通过动态检测一润、二润、打叶、复烤干燥、回潮等关键工段的常规化学成分变化,结合方差分析、相关性分析和主成分分析,系统评估不同工艺环节对总糖、还原糖、烟碱、总氮、石油醚提取物、钾离子和氯离子的调控作用。【结果】在打叶复烤生产过程中,各常规化学成分含量呈先升高后降低的动态变化趋势,在打叶工段达到峰值,经复烤干燥处理后各指标显著下降。方差分析表明:不同工段对总糖、烟碱、总氮、钾和石油醚提取物的调控作用达到极显著水平(P<0.01),氯含量在润叶及复烤工段中未发生显著波动。相关性分析表明:复烤工段与总糖、还原糖、烟碱、总氮和钾含量呈显著或极显著负相关。主成分分析进一步证实:复烤工段对化学成分的影响显著高于润叶工段,其中,干燥处理导致主成分得分急剧下降,而回潮工段仅能部分逆转该化学变化。【结论】复烤工段对上部烟叶常规化学成分的影响强于润叶工段,建议根据风格需求重点调控复烤工段的工艺参数,以提升烟叶质量。研究结果为改善云产黄金叶上部烟叶的工业可用性提供了关键数据支撑。
[Purpose]To investigate the dynamic effects of the leaf-threshing and re-baking pro-cesses on the conventional chemical components of upper tobacco leaves,providing a theoretical basis for optimizing re-baking parameters to improve tobacco quality.[Methods]Using upper leaves of Yunnan-produced Golden Leaf tobacco as research material,changes in conventional chemical com-ponents were monitored throughout key processing sections,including primary conditioning,second-ary conditioning,leaf-threshing,re-baking and drying,and dampening.Combined with variance ana-lysis,correlation analysis,and principal component analysis(PCA),the regulatory effects of different process sections on total sugar,reducing sugar,nicotine,total nitrogen,petroleum ether extract,po-tassium ions,and chloride ions were systematically evaluated.[Results]During the leaf-threshing and re-baking process,the content of each conventional chemical component showed a dynamic pat-tern of first increasing and then decreasing,peaking at the threshing section.After treatment of re-bak-ing and drying,these indicators decreased significantly.Variance analysis showed that different pro-cessing sections had extremely significant regulatory effects on total sugar,nicotine,total nitrogen,potassium and petroleum ether extract(P<0.01),while chloride content did not fluctuate significantly during conditioning and re-baking sections.Correlation analysis revealed that the re-baking section was significantly or extremely significantly negatively correlated with the contents of total sugar,re-ducing sugar,nicotine,total nitrogen,and potassium.PCA further confirmed that the re-baking sec-tion had a more substantial effect on chemical components than the conditioning section,with drying treatment causing a sharp decline,while the dampening section only partially reversed these chemical changes.[Conclusions]The re-baking section has a stronger effect on conventional chemical com-ponents of upper tobacco leaves than the conditioning section.It is recommended to focus on optimiz-ing re-baking process parameters according to style requirements to improve tobacco quality.The res-ults provide critical data support for enhancing the industrial usability of Yunnan-produced Gold Leaf upper tobacco leaves.
