In the present study, different hydrolysates were elaborated from
themuscle of thornback ray using different proteolytic enzymepreparations.
To study the nature of generated peptides, hydrophobicity, total
amino acids and molecular weight were characterized. TRMHs were
found to exhibit to a variable extent antioxidant and ACE inhibitory activities.
The differences in the antioxidant and ACE inhibitory activities
were strongly related to the enzymes used; which generate peptides
exhibiting different biological activities. TRMH-Neutrase with the
lowest DH exhibited the higher activities. Thornback ray muscle can
be used as a potential source of natural antioxidants and anti-ACE peptides.
Further, due to their high content of EAA, TRMHs could serve as a
potential protein source for animal diet formulations.
