“…While metabolomic analyses are generally used to explain changes in the physicochemical properties of various meat products and rely on various chemometric analyses ( Kim et al, 2020a ; Kim et al, 2020b ; Simmler et al, 2014 ), there has been an increase in the number of nuclear magnetic resonance (NMR)-based studies used to evaluate the metabolic profile of these meat samples without evaluating the chemical characteristics of the target metabolites ( Simmler et al, 2014 ). NMR-based analysis combined with multivariate analysis was used to understand and/or to elucidate metabolic changes of meat samples ( Kim et al, 2020a ; Kim et al, 2020b ). Several studies have used NMR-based analysis of meat samples to determine their metabolic profiles, and many of these profiles have been used to differentiate meat samples based on breed, age, geographical origin, and metabolic fingerprint as determined by one-dimensional 1 H NMR (1D 1 H NMR) analysis ( Beauclercq et al, 2016 ; Jung et al, 2010 ; Kodani et al, 2017 ; Straadt et al., 2014 ).…”
