河南省烤烟常规化学成分与烟叶有机酸含量关系分析
选取了河南省不同产区的353个烤烟样品为供试材料，测定了18种有机酸和8种常规化学成分，并分析了其相关关系。结果表明：不同种类有机酸的含量差异较大，以苹果酸的含量最高，柠檬酸次之，十五酸含量最小；富马酸的变异系数最高，软脂酸的变异系数最小；氯的变异系数最大，淀粉次之，总氮最小，为14％。烟碱和钾含量偏低，总糖和还原糖含量偏高；总氮、淀粉、氯和石油醚提取物含量都存在过高或过低的现象。常规化学成分与有机酸之间存在较强的相关性，其中，K＋属于与有机酸关系非常密切的指标；总氮、烟碱、还原糖、淀粉、总糖和石油醚提取物属于关系密切的指标；氯属于关系不密切的指标。...

Hongyunhonghe Tobacco （Group） Limited Company, Kunming 650202, China; 3. China Tobacco Hubei Industrial Corporation Limited, Wuhan 430512, China） Eighteen different organic acid contents and 8 different conventional chemical compositions were analyzed in 353 flue - cured tobacco samples from Henan province. Correlations were also studied between them. Results showed that the great difference existed among different kinds of organic acid. Malic acid had the highest content and citric acid took＇the second place, and pentadecanoic acid had the lowest content. Fumaric acid had the biggest coefficient of variation and palmitie acid took the minimum among the or- ganic acids. Chlorine had the biggest coefficient of variation and starch took the second place. The content of total nitrogen, which was only 14 percent, took the minimum among the conventional chemical c |
