NMR-based metabolomics for simultaneously evaluating multiple determinants of primary beef quality in Japanese Black cattle.

ABSTRACT: Analytical methodologies to comprehensively evaluate beef quality are increasingly needed to accelerate improvement in both breeding and post-mortem processing. Consumer palatability towards beef is generally attributed to tenderness, flavor, and/or juiciness. These primary qualities are modified by post-mortem aging and the crude content and fatty acid composition of intramuscular fat. In this study, we report a nuclear magnetic resonance (NMR)-based metabolic profiles of Japanese Black cattle to evaluate the compositional attributes of intramuscular fat and the long-term post-mortem aging. The unsaturation degree of triacylglycerol was estimated by the ¹H NMR spectra and was correlated with the content ratio of unsaturated fatty acids (R ² = 0.944) and the melting p
