To examine structural and biochemical changes in the endomysium and perimysium during semitendinosus muscle development and determine how they relate to pork toughness as pigs age.
Evaluated semitendinosus muscle samples from pigs spanning from neonates up to 55 months of age.
Measured meat toughness via shear force values and assessed connective tissue structural changes and collagen solubility across developmental stages.
Pork shear force values increased linearly until 6 months of age before the rate of increase slowed.
Secondary perimysium thickness correlated strongly and significantly with the rise in shear force value (r = .98).
Endomysial sheaths thickened alongside muscle fiber hypertrophy, while heat-soluble collagen decreased almost linearly, demonstrating increased nonreducible cross-linking with age.

Implication

Observational analysis demonstrates thickening perimysium drives pork toughness in growing pigs, indicating structural collagen maturation alters meat texture.
