Effect of Woody Breast Condition on Instrumental Texture Characteristics of Poultry Deli Loaves

Abstract

The use of broiler breast fillets affected by the woody breast (WB) condition in processed poultry products couldbe a feasible solution to this meat quality problem. This study assessed the impact of utilizing broiler breast fillets at differ-ent degrees of WB severity and percentages on instrumental texture characteristics of deli loaves. Breast fillets (n = 270) were collected from broiler carcasses and sorted based on palpation assessment in 3 WB categories (normal [NOR], mild [MIL], and severe [SEV]). Nine treatments of deli loaves were prepared from cubed portions in each of 3 replications: 100% NOR (T1), 67% NOR + 33% MIL (T2), 67% NOR + 33% SEV (T3), 33% NOR + 67% MIL (T4), 33% NOR + 67% SEV (T5), 100% MIL (T6), 67% MIL + 33% SEV (T7), 33% MIL + 67% SEV (T8), and 100% SEV (T9). Cooked deli loaves were subjected to texture profile analysis, cook loss, instrumental color, and dimensional modifications. Hardness of deli loaves increased (P < 0.05), whereas cohesiveness values decreased (P < 0.05), as WB severity increased in the meat added into the product formulation when compared with NOR samples and excluding treatments T2 through T4. The use of SEV fillets at 100% (T9) or mixtures of MIL and SEV fillets (T7 and T8) yielded nonuniform deli loaves with different color parameters and higher levels of cook loss (>13%), coupled with reductions in diameter (>8%) and length (>5%), comparedto NOR samples (P < 0.05). These results suggest that the negative effects of WB on quality and yield characteristics are not minimized by the preparation of this formed product when using high proportions of WB meat. Thus, broiler breast fillets affected by the WB condition may be used at relatively low percentages combined with NOR fillets as an option in commercial chicken deli loaf formulations.
