Development of a methodology to categorize poultry meat affected by deep pectoral myopathy

The growth of poultry production has led to an increase in the incidence internal defects chicken and turkey broilers, such as Deep Pectoral Myopathy (DPM). DPM is ischemic hemorrhage or necrosis caused by inadequate blood supply Pectoralis minor major muscles. Currently, visual appearance only parameter used categorize damage level. aim this research was develop a scientific methodology determine level breast tenders affected myopathy. For purpose, microstructure, pH, protein ion contents, color were studied. Results allowed identifying three levels: normal, hemorrhagic samples with hematomas clots, necrotic tissues, based on significant variables (p < .05) measured (pH, L* a*), where muscles myopathy presented values lower than 47, pH higher 6.05. Practical applications meat growing problem due intensive genetic selection fast rate that industry demands. This provides methodology, biochemical physicochemical parameters muscle tissue metabolism, develops validates categorization for deep pectoral broilers damage. work, objective coupled work published Traffano-Schiffo et al. (2018) patented, will allow detecting, identifying, characterizing chickens have suffered degree
