Changes in intramuscular collagen of cod (Gadus morhua) during post‐mortem storage in ice
Intramuscular collagen was isolated from the muscle of large and small cod (Gadus morhua L) stored in ice for periods up to 24 days. The solubilities in salt solution (salt soluble collagen), in dilute acetic acid (acid soluble collagen) and on heating (heat soluble collagen) were used as indices of...
