Abstract

Sea cucumber (Holothuria leucospilota) is a native species of Echinodermata that has long been used as traditional Asian medicine. This study was conducted for the evaluation of the antioxidant property of hydrolyzed protein with molecular weight of < 30-KDa extracted from H. leucospilota using Alcalase and Flavourzyme enzymes. Antioxidant activity was evaluated by DPPH radical scavenging assay and ferric reducing antioxidant power. The results of antioxidant experiments showed that with increasing concentration of hydrolyzed protein (both enzymes), the percentage of DPPH scavenging and ferric reducing increased and there was a significant difference between the different concentrations studied (P < 0.05). The inhibitory effects of the peptides extracted by the Alcalase were higher than that of Flavourzyme. It can be concluded that a hydrolyzed protein with a molecular weight < 30-KDa can be used as a natural source of antioxidant compounds in the pharmaceutical and food industries.
