Differences in phosphatidylcholine profiles and identification of characteristic phosphatidylcholine molecules in meat animal species and meat cut locations

Phosphatidylcholine (PC) is an essential component of the plasma membrane. Its profile varies with species and tissues. However, the PC profiles in meat have not been explored in depth. This study aimed to investigate the differences in PC profiles between various meat animal species and meat cut sites, along with the identification of characteristic PC molecules. The results demonstrated that the PC profiles of chicken meat differed from those of other species. Significant differences were also observed between the PC profiles of pork meat and the meat obtained from other species. The amount of PCs containing ether bonds was high in pork meat. PCs containing an odd number of carbon atoms were characteristic of beef and lamb meats. Furthermore, PC profiles differed based on the muscle location in chicken and pork. These results suggest that the PC profiles of skeletal muscles are indicators of animal species and muscle location. [GRAPHICS] .

Automated summary

The study found significant differences in PC profiles between different meat animal species and cut sites, with pork meat having high amounts of PCs containing ether bonds and beef and lamb meats containing PCs with an odd number of carbon atoms. Additionally, PC profiles varied based on muscle location in chicken and pork, suggesting that skeletal muscle PC profiles can be indicators of animal species and muscle location.
