How does the process of rigor mortis impact the water-holding capacity of meat?

Answer

It lowers water-holding capacity, potentially causing toughness and weeping.

Rigor mortis is the stiffening of the muscle that occurs after death due to the depletion of ATP and the interaction of muscle proteins in the absence of energy reserves. A critical consequence of this chemical state is that the contracted muscle fibers lose their ability to retain moisture effectively. When meat is cooked while in this rigid state, the diminished water-holding capacity leads to moisture loss, resulting in meat that feels tough to chew and may appear 'weepy' as the retained liquid is expelled during heating.
