In this study, 20 Yanbian yellow cattles (350±20) kg about 30 months’ age were randomly divided into four groups: the control group A (basal diet); test group B (0.1% yeast enriched selenium-germanium supplemented in basal diet); test group C (0.2% yeast enriched selenium-germanium supplemented in basal diet); test group D (0.3% yeast enriched selenium-germanium supplemented in basal diet). After the test cattle were feed for 100 days, they were standardized slaughtered and then stored at (4±1) ℃ for 48 h for acid discharge. The rump and striploin were picked for follow-up index measurement. In this experiment, the flavor changes of Yanbian beef were analyzed by electronic nose and electronic tongueusing principal component analysis, linear discriminant analysis and Sensor contribution rate to explore the effect of different selenium and germanium content on the flavor of yanbian beef. The results showed that the yeast enriched selenium and germanium affected beef odor, and the differences between the control group and the test group were mainly from nitrogen, oxygen compounds and sulfide. The yeast enriched selenium and germanium affected beef taste, compared with the control group, the rump and striploin from test groups had a higher output value.
