Abstract:The flavor of Moringa seeds of Indian traditional varieties，African varieties，and improved varieties in Yunnan，China in 10 producing areas was analyzed based on the electronic nose and the electronic tongue technologies.The extraction and detection conditions of odor components and taste substances were optimized.The odor and taste intensities were detected by electronic nose and electronic tongue respectively.Principal component analysis（PCA），discriminant factor analysis（DFA），radar chart and flavor profile analysis were employed for data analysis.The results of PCA and DFA showed that Moringa seeds of the same variety from different origins had the similar flavor，and the flavor of different varieties was quite different.The radar chart could directly reflect the differences in the odor and taste intensities of Moringa seeds of different varieties.As revealed by the results of flavor profile analysis，the Moringa seeds are bitter，salty，and fresh for Indian traditional varieties，sweet and sour for improved varieties in Yunnan，China，and moderate for African varieties.Electronic nose and electronic tongue can quickly and easily distinguish the flavor characteristics of different varieties of Moringa seeds，and provide new technical support for their variety identification.
