Abstract

This study aims to optimize enzymatic hydrolysis process for producing angiotensin I-converting enzyme (ACE) inhibitory peptides from protein hydrolysate of shortfin scad (Decapterus Macrosoma) waste (SWH). The enzymatic hydrolysis conditions namely the temperature (40 50 60C) time (B: 60 120 180 min) pH (C: 7 8 9) and enzyme substrate concentrations (D: 1 2 3) on yield degree of hydrolysis (DH) and ACE-inhibitory activity were analysed. Responses were optimized using the response surface methodology (RSM) by employing four factors 3-levels and the Central Composite Design (CCD). The optimized conditions were further validated to indicate the validity of the prediction model. The optimal conditions obtained for the hydrolysis conditions were at temperature of 50C time of 60 min pH of 9 and enzyme to substrate concentration of 2.92. The experimental result for yield was lower than the predicted value as generated by RSM. However the degree of hydrolysis of SWH was higher than the predicted value. The ACE inhibitory activity of SWH was 79.34 and showed lower than the predicted value. Therefore the optimized conditions of SWH served as good conditions for the production of bioactive peptide with high ACE inhibitory activity.
