The woody breast (WB) condition negatively influences the texture characteristics and quality of intact broiler breast fillets (Pectoralis major). But the impact of WB on ground meat is unknown. The objective of this study was to evaluate the effects of WB on the texture and cook loss of ground meat made of broiler breast fillets. Broiler breasts (deboned 3 h postmortem) were collected on 3 separate trial d from the commercial deboning line and classified into normal and severe WB fillet categories. Individual fillets were either ground and formed into patties or left intact prior to being stored for 7 d at -20°C. Samples were then cooked directly from the frozen state to an endpoint temperature of 76 °C for cook loss, instrumental (patties: Allo-Kramer shear; fillets: Warner-Bratzler shear), and descriptive sensory analysis of texture. Cook loss was greater (P < 0.05) in intact WB fillets compared to that in intact normal fillets, but there was no difference (P > 0.05) between WB and normal patties. There was no difference (P > 0.05) in shear force between normal and WB samples regardless of meat type. Sensory analysis showed that average scores of springiness and hardness of intact WB fillets were greater than those of normal fillets (P < 0.05). However, there were no significant differences (P > 0.05) in average scores for sensory attributes cohesiveness, hardness, juiciness, fibrous, and rate of breakdown between WB and normal patties. WB patties exhibited lower springiness and chewiness scores (P < 0.05) than normal patties. Data suggest that undesirable differences in sensory texture characteristics between cooked intact WB and normal breast meat can be minimized in a ground product.
木质胸肉(WB)状况会对完整鸡胸肉片(胸大肌)的质地特性和品质产生负面影响。但是,WB 对绞碎肉的影响尚不清楚。本研究的目的是评估 WB 对由鸡胸肉片制成的绞碎肉的质地和煮失率的影响。在 3 个不同的试验日,从商业去骨线上收集去骨后 3 小时的鸡胸肉,并将其分为正常和严重 WB 鸡胸肉类别。将单个鸡胸肉片进行绞碎并成型为肉饼,或者在 -20°C 下储存 7 天之前保持完整。然后,将样品直接从冷冻状态烹饪至 76°C 的终点温度,以进行煮失率、仪器(肉饼:Allo-Kramer 剪切;鸡胸肉片:华纳-布拉茨勒剪切)和质地描述性感官分析。与完整的正常鸡胸肉片相比,完整的 WB 鸡胸肉片的煮失率更高(P<0.05),但 WB 和正常肉饼之间没有差异(P>0.05)。无论肉类类型如何,正常和 WB 样品之间的剪切力均无差异(P>0.05)。感官分析表明,完整 WB 鸡胸肉片的弹性和硬度的平均得分均高于正常鸡胸肉片(P<0.05)。然而,WB 和正常肉饼之间的感官属性的凝聚性、硬度、多汁性、纤维状和分解率的平均得分没有显著差异(P>0.05)。WB 肉饼的弹性和咀嚼性得分低于正常肉饼(P<0.05)。数据表明,在绞碎产品中,可以最小化煮后 WB 鸡胸肉和正常鸡胸肉之间感官质地特性的不良差异。
