Why Meat Sometimes Twitches After Slaughter

when an animal is slaughtered, the electrical signals that control muscle contractions cease. However, there can still be stored electrical energy within the muscle tissue. This energy may cause the muscles to contract spontaneously, resulting in the twitching or jumping movements observed in the meat. This phenomenon is known as muscle memory.

Muscle memory is a temporary condition that occurs immediately after death and lasts for a short period of time, typically a few minutes or hours. It is caused by the release of calcium ions from the sarcoplasmic reticulum, which is a network of tubules and sacs within muscle cells that stores calcium ions. When calcium ions are released, they bind to troponin, which is a protein that helps to regulate muscle contractions. This binding of calcium ions to troponin causes the muscle fibers to contract.

The twitching or jumping movements observed in meat are caused by the spontaneous release of calcium ions from the sarcoplasmic reticulum. This release of calcium ions can be triggered by a variety of factors, such as changes in temperature, pH, or the presence of certain chemicals.

Muscle memory is a natural phenomenon that occurs in all animals, including humans. It is not a sign of life, but rather a result of the body's natural processes after death
