Abstract

Abstract In this study, 206 breast fillets were purchased from grocery stores in the province of Quebec and evaluated for the presence of different quality defects. Of these fillets, 48.5% showed breast muscle myopathies (BMM), 19.4% showed pale, soft, and exudative (PSE), and 6.8% showed dark, firm, and dry (DFD) attributes. BMM were equally present (P > 0.05) in fillets of economical, commercial, and high-quality brands, while PSE-like fillets were more present in economical brands (P < 0.0001). The combined effect of BMM and DFD induced significantly higher counts of Salmonella (P = 0.03) and Enterobacteriaceae (P = 0.03) in myopathic than in unaffected fillets. These quality defects also altered the nutritional quality of breast meat: BMM-affected fillets had greater fat content (P < 0.0001) and DFD fillets had lower protein content (P = 0.041) than normal fillets. The technological quality was only slightly impacted by BMM, while PSE-like fillets had higher cooking loss (P = 0.009) and a tougher texture after cooking (P < 0.0001) than DFD fillets. For the first time, this study confirmed the presence of multiple quality issues in the Quebec poultry supply chain, and provided valuable data to support future research efforts.
魁北克零售市场肉鸡胸肉品质调查
摘要在这项研究中,从魁北克省的杂货店购买了206块胸脯肉,并对其是否存在不同的质量缺陷进行了评估。在这些鱼片中,48.5%表现为胸肌肌病(BMM),19.4%表现为苍白、柔软和渗出性(PSE),6.8%表现为深色、坚硬和干燥(DFD)。BMM在经济、商业和优质品牌的鱼片中同样存在(P>0.05),而PSE样鱼片在经济品牌中更为常见(P<0.0001)。BMM和DFD的联合作用导致肌病鱼片中沙门氏菌(P=0.03)和肠杆菌科细菌(P=0.03)的计数显著高于未受影响的鱼片。这些质量缺陷也改变了胸肉的营养质量:与正常鱼片相比,BMM影响的鱼片脂肪含量更高(P<0.0001),DFD鱼片蛋白质含量更低(P=0.041)。BMM对工艺质量的影响很小,而PSE样鱼片的烹饪损失更高(P=0.009),烹饪后质地更硬(P<0.0001)。这项研究首次证实了魁北克家禽供应链中存在多种质量问题,并为支持未来的研究工作提供了宝贵的数据。
