摘要
为了区分贵州香禾糯不同品种所具有的香味特征,利用电子鼻PEN3系统对贵州香禾糯高供鬼、苟央当、沟担当、苟岑高、从江香禾糯、苟高千的香味主成分进行采集和分析,同时利用主成分分析法和线性判别法对香味特征响应值进行数据分析并利用GC-MS对比苟高千和来陇的香味成分,结果证明电子鼻PEN3可以有效区分贵州香禾糯不同品种的香味特征。
For distinguishing and classifying the fragrant character among the aromatic glutinous rice which were the Gao Gonggui, Gou Yangdang, Gou Dandang, Gou Cengao, Congjiang Xianghenuo and Gou Gaoqian from Guizhou province, we analyzed the major aromatic components by using the electronic nose （PEN3）. The fragrant response value were obtained and analyzed by the principal component analysis （PCA） and linear diserimination analysis （LDA） of PEN3 systems. The fragrant components of Gou Gaoqian and Lai long were compared by the GC-MS. The results showed that electronic nose identify effectively the difference among the aromatic glutinous rice.
