ResumoThe objective of this study was to report the incidence of pale, soft, and exudative (PSE) turkey breast meat at a commercial plant in southern Brazil and the consequences on the quality of meat processing. This study was subdivided into 2 experiments: I) incidence of PSE meat and II) effects on meat processing. Experiment I: A total of 2610 breast filets were collected, and pH and color were tested. A value of 53.0 was determined using a Minolta lightness test (L*) as the cutoff value for PSE meat characterization. The incidence of PSE meat was 41.7%. Experiment II: A total of 16 filets in natura, 8 PSE and 8 normal samples, were analyzed for pH, color, and water holding capacity (WHC); they were processed into smoked products and yield, color, pH, texture, and moisture were evaluated. Functional properties were compared between PSE and normal meat samples; a 5.5% lower WHC was identified as the consequence of color abnormality. Finally, these PSE meat samples were processed into smoked meat, and the product was 31.3% harder than processed normal meat. The results showed approximately 5%–10% weight loss in PSE meat, with a risk of serious some economic losses for the poultry industry.
