Summary
Bioactive peptides that originate from different sources, such as plant, animal, fungi, bacteria, and venom, are specific protein fragments that have positive effects on the body functions and health of living organisms. Most of the discovered bioactive peptides from different protein sources showed various biological features, such as antihypertension, antioxidant, antithrombotic, antimicrobial, and anticancer immunomodulation. The aim of this study is the evaluation of biological activities of stingray (Dasyatis pastinaca) muscle tissue protein hydrolysate. Therefore, the homogenized muscle tissue of stingray was hydrolyzed by esperase and trypsin enzymes. Enzyme/substrate ratio, hydrolysis time, and degree were optimized. Moreover, the antioxidant (CUPRAC method) and metal chelating (copper chelating) activities of the hydrolysates were evaluated.
