摘要
DFD(dark,firm,dry)牛肉与正常牛肉品质差异明显,其较高的发生率每年都会给全球鲜肉市场造成巨大的经济损失。该文综述了DFD牛肉较正常牛肉的异常理化特征及其产生原因,并采用基因组学和蛋白组学从细胞骨架与肌肉收缩、线粒体和代谢、糖酵解和糖异生、热休克蛋白等方面详细探究了DFD牛肉形成机理,进一步总结分析了根据肉色、极限pH、糖原含量或糖酵解潜力鉴定DFD牛肉的方法,提出了添加有机酸、气调包装等宰后控制措施,旨在为DFD牛肉控制研究和实践提供参考。
The quality of DFD(dark,firm,dry)beef is different from that of normal beef,and its occurrence causes significant financial losses globally to the fresh meat market.This review analyzes the abnormal characteristics of DFD beef compared with normal beef and its mechanism using genomics and proteomics from the cytoskeleton and muscle contraction,mitochondria and metabolism,glycolysis and gluconeogenesis,heat shock protein and other aspects.This review summarizes and analyzes methods of identifying DFD beef based on meat color,ultimate pH,glycogen or glycolytic potential.It also proposes post-mortem control measures such as adding organic acid and using modified atmosphere package on beef,to provide references for DFD beef control research and practice.
