Abstract In this study, the differences in the contents of inosine acid, inosine, hypoxanthine and glutamic acid, aspartic acid and equivalent umami concentration (EUC) were investigated in pork Longissimus dorsi muscles from four commercial breeds, Northeastern indigenous pigs, Beijing black pigs, Wuzhishan pigs and Duroc × Landrace × Yorkshire crossbred pigs (DLY). The results showed that the content of inosine acid in meat of Northeastern indigenous pigs was the highest, which was significantly higher than that in the other three breeds (P < 0.05), while the content of hypoxanthine was the lowest (P < 0.01). The content of aspartic acid in meat of Beijing black pigs was higher than that in any other breed (P < 0.05), and the content of glutamic acid was significantly higher than that in Northeastern indigenous pigs and Wuzhishan pigs (P < 0.01). The contents of glutamic acid and aspartic acid in meat of Wuzhishan pig were significantly lower than those in the other breeds (P < 0.05). EUC in meat of Northeastern indigenous pigs, Beijing black pigs and DLY pigs was significantly higher than in Wuzhishan pigs (P < 0.01).
