ACID RIGOR Meaning and
Definition
-
Acid rigor refers to a phenomenon that occurs in the muscle tissue of animals shortly after they have been slaughtered. It is a biochemical process that involves the accumulation of lactic acid in the muscles, resulting in a drop in pH and a subsequent stiffening of the muscle fibers. The decrease in pH occurs due to the anaerobic metabolism of glucose within the muscle tissue, leading to the formation of lactic acid as a byproduct.
This condition is usually observed in meat from animals that have experienced stressful conditions before slaughter, such as transportation or confinement, as well as those that have engaged in intense physical activity. These factors can contribute to an increase in glycogen breakdown and subsequent lactic acid production within the muscles.
The consequence of acid rigor is a reduction in the quality and tenderness of the meat, as the stiffening of the muscle fibers makes it more difficult for water to bind to the protein molecules. This can lead to a tougher texture and diminished flavor in the end product. However, acid rigor can be mitigated through various post-slaughter practices such as prompt chilling of the carcass, electrical stimulation, or the addition of certain additives.
In summary, acid rigor is a condition that occurs in meat due to the excess accumulation of lactic acid in the muscle tissue, resulting in a drop in pH and subsequent stiffness. It is influenced by the animal's physical activity levels and the presence of stressors prior to slaughter.

Etymology of ACID RIGOR
The term "acid rigor" does not have a specific etymology on its own because it is not a commonly used or recognized term. It appears to be a combination of two separate words: "acid" and "rigor". Here is the etymology of each word:
1. Acid:
The word "acid" comes from the Latin term "acidus" meaning "sour". It was first used in English in the 1620s to refer to a substance with a sour taste. The Latin "acidus" is derived from the Proto-Indo-European root "ak-", which means "sharp" or "pointed".
2. Rigor:
The word "rigor" comes from the Latin "rigor" meaning "stiffness" or "rigidity". It was originally used in English during the 16th century to describe physical stiffness or the severity of something.
