There are different ways to define meat quality and various compounds may be employed as indicators of its quality. Progress observed in biological sciences, especially in proteomics, indicates that proteins building meat structures as well as those taking part in metabolic processes, by being a constituent part of enzymes, can provide indicators of meat quality. Meat quality, from the practical point...
