In order to explore the influence of lotus rhizome varieties on the quality of lotus seed, six main varieties of lotus root were selected to prepare lotus seed, and their surface color, texture characteristics, water content and fat content were measured. The volatile flavor components of lotus seed were analyzed by electronic nose and headspace solid phase microextraction coupled with gas chromatography mass spectrometry (HS-SPME-GC-MS). Finally, combined with sensory score, comprehensive evaluation was carried out. The results showed that the brightness values L* and b* of 'Lulinhu' rhizome balls were significantly higher than that of the others (P
