云南省新烟区烟叶与津巴布韦烟叶致香成分比较分析

摘要

对云南省新烟区(文山、保山、临沧、普洱)与津巴布韦(马龙德拉、宾杜拉、奇诺伊)烟区生产的KRK26烟叶的致香成分进行了比较分析.结果表明,新烟区上部烟叶新植二烯含量高于津巴布韦烟叶,津巴布韦烟叶挥发性酮类、挥发性醛类、杂环类含量高于新烟区烟叶.新烟区中部烟叶新植二烯含量高于津巴布韦烟叶,津巴布韦烟叶挥发性酮类、挥发性醛类、挥发性醇类、杂环类含量明显高于新烟区烟叶.新烟区下部烟叶多元酸及高级脂肪酸、新植二烯含量高于津巴布韦烟叶,津巴布韦烟叶挥发性酮类、挥发性醇类含量高于新烟区烟叶.主成分分析结果表明,上部烟叶普洱烟叶与马龙德拉、奇诺伊烟叶更加相似,中部烟叶临沧烟叶与马龙德拉烟叶更加相似,下部烟叶新烟区烟叶与马龙德拉烟叶更加相似.%Comparison of flavor related compounds between Yunnan new tabacco growing areas ( Wenshan , Baoshan , Lincang , Pu ' er) and Zimbabwe( Marondera, Chinoy, Bindura) flue-cured tobacco KRK26 was carried out in our study. The results showed that the neophytadiene content of Yunnan new tobacco growing areas upper leaf ia higher than that of Zimbabwe leaf, while the content of volatile ketones . volatije aldehydea and heterocyclic compounds are lower than Zimbabwe leaf. The neophyladiene content of Yunnan new tobacco growing areas cutter leaf is higher than Zimbabwe leaf and the content of volatile ketones, volatile aldehydes, volatile alcohola and heterocyclic compounds aue lower than Zimbabwe. The content of polyatomic acids, higher fatty acids and neophytadiene are higher in Yunnan new tohacco growing areas lower leaf than Zimbabwe leaf, while the content of volatile ketones and volatile alcohols are lower than Zimbabwe leaf. Principal component analysis ahowed thst Pu ’ er leaf had higher aimilarity with Marondera and Chinoy leaf in upper leaf, Lincang leaf had higher similarity with Marondera leaf in cutter leaf, Yunnan new tobacco growing areas and Marondera had higher similarity in lower leaf.
