| Research Abstract |
High hydrostatic pressure tenderized bovine intramuscular connective as well as meat. Morphological study by scanning electron microscopy revealed that high pressure induced structural weakening of intramuscular connective tissue, especially collagen fiber networks in perimysium and perimysial-endomysial junction. Degradation of collagen molecules by high pressure could not be shown, while dissociation of collagen fibers or fibrils into fibrils or molecules could be found. High hydrostatic pressure can therefore not degrade the intramuscular collagen molecules but can weaken the association of collagen molecules and fibrils, which might be involved in tenderizing followed by structural weakening of intramuscular connective tissue.
