Antioxidant and angiotensin I-converting enzyme inhibitory properties of oligopeptides derived from black-bone silky fowl (Gallus gallus domesticus Brisson) muscle

► We describe a practical way to utilize black-bone silky fowl muscle. ► One potent antioxidant peptide is identified from the hydrolysate. ► Two novel potent ACE inhibitory peptides are identified from the hydrolysate.
