NMR-based comparison of the metabolome of beef from Simmental and black-and-white young bulls during wet- and dry-aging

Abstract Taste as an eating quality factor of beef can be influenced by the selection raw material and aging method. The metabolic changes different breeds during were analyzed in wet-aged dry-aged up to 28 days using samples from M. longissimus thoracis et lumborum Simmental Black-and-White 1 H NMR spectroscopy. Breed affected metabolome before beef. concentration 24 30 metabolites differed significantly ( P < 0.05) unaged both breeds. In addition, time type showed partially effects on caused breed. Aging Aspartate, betaine, creatinine, glycine, niacinamide correlated with only Five (carnitine, creatine, inosine 5’ monophosphate, lactic acid O-acetyl- l -carnitine) varied between
