Technical Abstract: Meat quality is a function of many different processes that occur during the growth of the animal and after slaughter. It is important for the meat industry to be able to adequately assess the quality of meat before it is presented to consumers. The NMR properties of the chemical components of meat can be used to evaluate a number of parameters related to meat quality, including: the fat content and distribution, water content, water holding capacity, collagen content, pH, and metabolites such as lactate, glycogen, phosphocreatine and ATP. Both MRI and NMR spectroscopy have been used extensively to evaluate the composition and quality meat. NMR spectroscopy has been particularly useful in studying post-mortem metabolism and the resulting quality factors of pH and water distribution (water holding capacity). Advances in MRI techniques show promise for the application of MRI for determining the fat and lean content of certain cuts of meat and to assess meat quality in terms of intramuscular fat and collagen content.
