What is meat rigor mortis?

Rigor mortis is a loss of muscle extensibility marking the conversion of muscle to meat. In other words, living muscles can be stretched and they return to their resting length when released. Meat cannot be stretched and has very little elasticity. A strong attempt to stretch a length of meat will merely rip it.

What is post rigor aging?

Rigor mortis in muscle tissue is usually resolved 2–3 days post mortem. By this time, the meat again becomes soft and tender (in case of beef especially). Further aging of the meat to improve tenderness and to form aroma requires various amounts of time, depending on the temperature.

What is rigor mortis in food microbiology?

Rigor mortis is defined by the decline of ATP to zero, 0% extensibility, an ultimate pH that is reached, and the production of lactic acid that has plateaued. From: Encyclopedia of Food and Health, 2016.

What is pre rigor meat?

“Pre-Rigor sausage” or “whole hog” pork sausage are names for fresh pork sausage made from pork carcasses immediately (within one hour) after slaughter. Hot boning allows the processor to salt the meat before the muscle has gone into rigor mortis.
