摘要
【目的】明确影响上部烟叶感官质量最主要的化学成分。【方法】测定国内外6个产地共107份上部烟叶样品主要化学成分,评价其感官质量,分析化学成分指标与感官质量总分的关系;对比分析了国内外主产烟区8032份上部烟叶样品的3项主要化学成分。【结果】①简单相关分析显示,总糖、还原糖含量与感官质量呈显著或极显著的正相关关系,总氮、烟碱含量与感官质量呈显著或极显著的负相关关系;②逐步回归和通径分析显示,影响上部烟叶感官质量的最主要化学成分为总氮、总糖、烟碱。③国内多数主产烟区上部烟叶总氮含量均高于国外上部烟叶,总糖、烟碱含量接近于或者高于国外上部烟叶。【结论】要提高上部烟叶感官质量,应着重控制总氮含量,协同控制烟碱含量和提高总糖含量。
[Objective] To clarify main chemical components affecting the sensory quality of the upper tobacco leaves. [Method] The main chemical constituents of 107 upper tobacco leaf samples from 6 producing areas at home and abroad were determined, and their sensory quality was evaluated. The relationship between chemical composition index and sensory quality total score was analyzed. The three main chemical components of 8032 upper tobacco leaves from main tobacco producing areas at home and abroad were compared and analyzed. [Results] ① Simple correlation analysis showed that there was a significant or extremely significant positive correlation between total sugar or reducing sugar content and sensory quality. There was a significant or extremely significant negative correlation between total nitrogen & nicotine content and sensory quality. ②Path analysis showed that the most important three chemical components affecting the sensory quality of the upper tobacco leaves were total nitrogen, total sugar, and nicotine. ③Compared with the upper leaves of tobacco from foreign producing areas, the upper leaves of tobacco from major domestic tobacco producing areas have a higher total nitrogen content, and a similar or higher total sugar and nicotine content. [Conclusion] To improve the sensory quality of the upper tobacco leaves, we should focus on controlling the total nitrogen content, synergistically control the nicotine content and increase the total sugar content.
