雪茄烟种质常规化学成分、多酚与感官质量的相关性分析

为便于雪茄烟种质资源品质性状的评价,采用DPS(Data Processing System)对50份雪茄烟种质资源的烟叶化学成分、多酚与感官质量进行简单相关和典型相关分析。结果表明:雪茄烟种质资源的烟叶化学成分与多酚及感官质量之间均存在显著典型相关关系。烟叶化学成分与感官质量关系最密切,与多酚的关系较密切;多酚与感官质量的关系密切。还原糖、总氮、钾、总植物碱等化学成分与多酚物质(隐绿原酸、新绿原酸、莨菪亭、绿原酸)密切相关;还原糖、总糖等化学成分与感官质量(浓度、余味、刺激性、香气质、灰色、杂气)密切相关,多酚(新绿原酸、隐绿原酸、莨菪亭)与感官质量(香气质、香气量、刺激性)相关性较密切。由此可见,雪茄烟种质资源的化学成分、多酚和感官质量之间有一定的相关性。

Correlation Analysis of Routine Chemical Components,Polyphenol and Sensory Quality of Cigar Germplasm Resources

In order to facilitate the evaluation of quality traits of cigar germplasm resources, this paper conducted simple correlation and typical correlation analysis on the chemical components, polyphenol and sensory quality of 50 cigar germplasm resources by DPS (data processing system). The results showed that there were significant typical correlations between the chemical components and polyphenol, sensory quality of cigar germplasm resources. The relation between the chemical component and sensory quality was the closest, that with polyphenol was closer, and that between polyphenol and sensory quality was close. The results also revealed that the reducing sugar, total nitrogen content, potassium, nicotine had close correlation with the polyphenol (cryptochlorogenic acid, neochlorogenic acid, chrysatropic acid, chlorogenic acid); and chemical components (reducing sugar, total sugar,etc.) also had close correlation with sensory quality (concentration, aftertaste, irritation, aroma quality, gray, offensive odor) ; while the polyphenol (neochlorogenic acid, cryptochlorogenin acid, chrysatropic acid) had closer correlation with sensory quality (aroma quality, aroma quantity, irritation). These results showed that there were certain correlations between chemical components, polyphenol and sensory quality of cigar germplasm resources.
