Comparison on DPPH scavenging effects of porcine hemoglobin hydrolysate prepared using six proteases. Six proteases: (
)Flavorzyme, (
)Trypsin, (
)Papain, (
)A.S.1398, (
)Alcalase, (
)Pepsin. Native porcine hemoglobin (■) was adopted as control. The hydrolysate with the highest DPPH radical scavenging activity was indicated by an arrow. The values are means ± SD of triplicate measurements
