Implication

Experimental study reveals intramuscular variation in Warner-Bratzler shear force in broiler fillets, indicating measurement stability depends on location, aging, and storage.

Key Points

To evaluate intramuscular variation and Pearson correlation coefficients of Warner-Bratzler shear force measurements within early deboned broiler breast fillets under different deboning and cold storage conditions.
Broiler breast fillets were harvested at early (2 h) or late (24 h) postmortem intervals.
Early deboned fillets were subjected to four storage treatments: 0 d, 7 d at 3 °C, 7 d at -20 °C, or 6 d at -20 °C followed by 1 d at 3 °C.
Cooked fillet tenderness was quantified across distinct anatomical locations using a texture analyzer equipped with a Warner-Bratzler shear blade.
Warner-Bratzler shear force differed among locations within individual fillets, but within-fillet variation was notably smaller than variation observed between separate fillets.
Pearson correlation coefficients between measurement locations were statistically significant, although the strength of correlation depended on the specific paired locations.
Postmortem deboning interval and cold storage conditions significantly altered location-specific shear force values and their inter-location correlation coefficients.
