烤烟烟叶理化指标与浓香型风格程度的关系

检测评价了河南省驻马店烟区60个C3F烟叶样品的理化指标与浓香型风格程度,并采用相关分析、逐步回归分析等方法研究了烟叶理化指标与浓香型风格程度的关系。结果表明:①烟叶厚度、钾、巨豆三烯酮A,巨豆三烯酮B,巨豆三烯酮C与浓香型风格程度显著正相关,挥发性碱、山奈酚糖苷、糠醛、糠醇、5-甲基糠醛、巨豆三烯酮D与浓香型风格程度极显著正相关,还原糖与浓香型风格程度显著负相关,芳樟醇、金合欢基丙酮、香叶基丙酮、β-紫罗兰酮、2-乙酰呋喃与浓香型风格程度极显著负相关;②糠醛、5-甲基糠醛、2-乙酰呋喃、香叶基丙酮与烟叶浓香型风格程度存在极显著回归关系,共同决定了烟叶浓香型风格程度变化的88.7%,是影响烟叶浓香型风格程度的主要指标。

Relationship Between Physical-chemical Indexes and Full Flavor Style Degree of Flue-cured Tobacco Leaves

Sixty C3F samples of flue-cured tobacco leaves were collected from Zhumadian to analyze the relationship between physical-chemical indexes and full flavor style degree of leaves with correlation analysis and stepwise regression analysis.The results showed that: 1) the full flavor style degree of leaves significantly positively correlated with leaf thickness,potassium,megastigmatrienone A,megastigmatrienone B,and megastigmatrienone C;extremely significantly positively correlated with volatile base,kaempferol-3-rutinoside,furfural,furfural alcohol,5-methyl furfural,and megastigmatrienone D;while significantly negatively correlated with reducing sugar;extremely significantly negatively correlated with linalool,farnesylacetone,geranyl acetone,β-ionone,2-acetyl furan;2) there was an extremely significant regression relationship between full flavor style degree of leaves and furfural,5-methyl furfural,2-acetyl furan,geranyl acetone,which were the major components affecting the full flavor style degree of leaves,and determined about 88.7% of the changes of full flavor style degree of leaves.
