Abstract
Fish protein hydrolysates from whole kilka, using alcalase enzyme (ratio 1: 100) under optimal temperature (55°C) and pH (8.5) was evaluated for its hydrolysis degree and antioxidant activity. Results of the hydrolysis degree recorded at time intervals of 1, 2, 3 and 4 hours indicated the hydrolysis degree increased with increase in the hydrolysis time. The evaluation of FPH antioxidant activity, using DPPH, ABTS and reducing power assay tests at 3 concentrations (1, 2 and 5 mg/ml indicated the highest inhibitory effect at 5 mg/ml was 74.4%, 72.3% and 1.8 absorbance in 700 nm for DPPH, ABTS and reducing power assay, respectively. Generally, the findings of this research confirmed the potential of kilka as a source of natural antioxidants for food applications.
