Effect of trisodium phosphate solutions washing on the sensory evaluation of poultry meat

The effect of trisodium phosphate (TSP) solutions treatments on the sensory evaluation of poultry meat has been explored since TSP was recently approved by USDA for its usage in poultry processing to eliminate Salmonella contamination. In the present study, fresh chicken thighs were dipped in water (control sample) and in 8, 10 and 12% TSP solutions (treated samples) for 15 min. Raw samplesʹ color, smell and overall acceptability and cooked thighsʹ color, smell, flavor, texture and overall acceptability were evaluated by consumer panelists. The evaluation of raw pieces after treatment or after 7 days storage at 2°C revealed that, with the exception of 12% TSP solutions treatment, sensory quality was not adversely affected by TSP. The color, smell and overall acceptability hedonic scores for the boiled thigh meat were not different between the treated samples and the control ones. Only the color, flavor and overall acceptability of thighs dipped in 12% TSP were rated significantly lower than the control sample. These results suggested that TSP solutions have good potential as dips to sanitize chickens carcasses
