Salmon skin collagen

Figure 23.6. Proliferation of fibroblast on salmon skin collagen laminated squid fi-chitin sheet (Takai, 1996).

Salmon skin or cartilage collagen has been used as food additives, in tablets or powders. Carefully prepared salmon skin collagen is also used as gel for cell growth, since it yelds higher performance than porcine collagen.

Nowadays, ACE inhibitory peptides have been isolated from meat, remaining muscle proteins, skin collagen and gelatin, bone, and internal organs of fishes such as Alaska pollack, bonito, tuna, salmon, shark, and sardine. Table 16.1 provides a partial summary of ACE inhibitory peptides derived from marine fish sources, their amino acid sequence, the enzyme used for hydrolysis, and IC50 values. The IC50 value is the concentration of peptide that inhibits 50% of ACE activity.
