Functional properties and in vitro antioxidant activity of roe protein hydrolysates of Channa striatus and Labeo rohita

► Roe protein hydrolysates were produced from roes of channa and labeo using alcalase. ► Yields of hydrolysates were 24.15% in channa and 12.45% in labeo with 58% protein. ► The protein solubility was higher in channa (90.48%) than labeo (50.60%). ► SDS-PAGE profile showed smaller peptides of 12 kDa in both CRPH and LRPH. ► DPPH activity and ferric reducing power were higher in CRPH than in LRPH.
