After slaughter, the muscle undergoes several post-mortem changes that impact its physical properties. The most significant change is the conversion of muscle to meat, which begins immediately after death. One of the first changes is the cessation of blood circulation, leading to the depletion of oxygen in the muscle tissue. This causes the muscle cells to switch from aerobic to anaerobic metabolism, leading to the accumulation of lactic acid. The pH of the muscle drops from its normal value of around 7.0 to a more acidic range of 5.3 to 5.7. As the pH decreases, the muscle proteins, particularly myofibrillar proteins
