Notes:
Electron microscopy was used to follow changes in porcine muscle during the 24-hr post-mortem chilling period. Ante-mortem subjection to elevated temperatures or to elevated temperatures and then chilling was used to produce different rates and magnitudes of change in post-mortem muscle color, texture, and water binding. Normal muscle exhibited a gradual disruption of sarcoplasmic components, with little if any change in the myofibrils. Muscle that went into rigor rapidly at a low pH and high temperature ultimately appeared soft, pale, and watery, and electron micrographs revealed a rapid disruption of sarcoplasmic components and some disorganization of the myo-filaments. Muscle that went into rigor rapidly at a high pH and a reduced temperature ultimately appeared dark, firm, and dry, and electron micrographs revealed a high degree of organization and preservation of myofibrillar structure.
