To determine the amino acid profile, peptide molecular size distribution, antioxidant efficacy, and enzyme inhibitory activities of fava bean protein hydrolyzates prepared using six commercial proteases.
Generated fava bean protein hydrolyzates using six proteases: alcalase (ALCH), chymotrypsin (CHYH), flavourzyme (FAVH), pepsin (PEPH), thermoase (THEH), and trypsin (TRYH).
Characterized amino acid profiles and peptide molecular weight distributions across all enzymatic preparations.
Assayed antioxidant activities (superoxide/hydroxyl radical scavenging and linoleic acid peroxidation inhibition) and measured inhibition against alpha-glucosidase, pancreatic lipase, arginase, alpha-amylase, angiotensin-converting enzyme, and renin.
FAVH and PEPH exhibited significantly higher contents of histidine and proline, respectively (p < .05), with ALCH, FAVH, TRYH, and CHYH demonstrating narrower peptide size distributions (0.19–4.9 kDa) compared to PEPH (0.19–6.9 kDa) and THEH (0.19–11.3 kDa).
FAVH showed significantly stronger superoxide and hydroxyl radical scavenging capacity and superior inhibition of linoleic acid peroxidation compared to all other hydrolyzates (p < .05).
FAVH exhibited the strongest inhibition of alpha-glucosidase, pancreatic lipase, and arginase (p < .05), whereas PEPH had the strongest inhibition of alpha-amylase and angiotensin-converting enzyme (p < .05), and THEH showed maximal renin inhibition.
