摘要
以西南烟区4个市的C3F烟叶样品为研究对象,分析了烤烟色度与中性香气成分含量关系。结果表明:色度与多数中性香气成分呈二次曲线关系,其中色度与6-甲基-5-庚烯-2-酮呈显著二次曲线关系,当色度分值为6.12时,6-甲基-5-庚烯-2-酮含量达到最大,为0.76μg/g。色度与苯乙醛、苯乙醇呈极显著的二次曲线关系,当色度分值为3.75和6.15时,苯乙醛和苯乙醇达到各自的最大值0.60μg/g和2.24μg/g。
The relationships between the chroma and neutral aroma component contents in the C3F tobacco leaf samples from four cities of southwest tobacco area were studied.A conic relationship was found between the chroma and most neutral aroma component contents.There was a significant conic relationship between the chroma and 6-methyl-5-hepten-2-ketone content,when the score of chroma was 6.12,the content of 6-methyl-5-hepten-2-ketone reached the maximum value 0.76 μg/g.There were extremely significant conic relationships between the chroma and phenylacetaldehyde,benzeneethanol contents,when the score of chroma was 3.75 and 6.15,the contents of phenylacetaldehyde and benzeneethanol reached the maximum value 0.60 μg/g and 2.24 μg/g respectively.
