Abstract
The growth of NMR foodomics is described in the context of a study of beef storage. Thirty samples of three meat cuts (chuck, sirloin, and tenderloin) were analyzed using 1H NMR spectroscopy to determine the influence of storage period and temperature. 1H showed signals belonging to metabolites namely: acetate, adenosine, adenine, ADP, alanine, betaine, creatine, creatinine, carnosine, fumarate, glycerol, glycine, glutamine, isoleucine, lactate, leucine, methionine, and valine. The score plots (PCA) separated the samples of different storage time, reflecting possible meat degradation. Samples of no storage time (time zero) were grouped in the PC1 and PC2 negatives axis. The score plots suggest that the temperature has a huge influence on the degradation extent and possible influences the growth of the microbial populations.
期刊介绍：
Concepts in Magnetic Resonance Part A brings together clinicians, chemists, and physicists involved in the application of magnetic resonance techniques. The journal welcomes contributions predominantly from the fields of magnetic resonance imaging (MRI), nuclear magnetic resonance (NMR), and electron paramagnetic resonance (EPR), but also encourages submissions relating to less common magnetic resonance imaging and analytical methods.
Contributors come from academic, governmental, and clinical communities, to disseminate the latest important experimental results from medical, non-medical, and analytical magnetic resonance methods, as well as related computational and theoretical advances.
Subject areas include (but are by no means limited to):
-Fundamental advances in the understanding of magnetic resonance
-Experimental results from magnetic resonance imaging (including MRI and its specialized applications)
-Experimental results from magnetic resonance spectroscopy (including NMR, EPR, and their specialized applications)
-Computational and theoretical support and prediction for experimental results
-Focused reviews providing commentary and discussion on recent results and developments in topical areas of investigation
-Reviews of magnetic resonance approaches with a tutorial or educational approach
