Abstract |
Octopus ocellatus, a marine cephalopod distributed in the coast of South Korea, China, Japan and tropical sea, contains high amounts of taurine. In this study, an enzymatic hydrolysate obtained from O. ocellatus meat was evaluated for its antioxidant effects using a human liver cell line and zebrafish embryo model. Enzymatic hydrolysates of the O. ocellatus meat (OOM) were prepared using six different enzymes. Among the enzymatic hydrolysates, Alcalase hydrolysate of OOM (OOMAH) showed the highest scavenging effects against 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azino-bis(3-ethylbenzthiazoline)-6-sulfonic acid (ABTS) radicals and hydrogen peroxide (H2O2). Moreover, it showed a high oxygen radical absorbance capacity (ORAC). OOMAH treatment effectively reduced the hydroxyl radical-induced DNA damage. OOMAH reduced the production of reactive oxygen species (ROS) in H2O2-treated hepatocytes without cytotoxicity. Furthermore, OOMAH improved the survival rate and reduced the intracellular ROS levels in H2O2-treated zebrafish embryos. Compositional analysis of amino acids indicated a high content of taurine in OOMAH. Current results suggest that OOMAH possesses antioxidant bioactivities and could provide protective effects against H2O2-induced oxidative stress. Therefore, OOMAH might be used as a potential resource of functional foods. |
