This study investigated the effects of steaming on the antioxidative activities of ray hydrolysates in vitro. Based onthe results of 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, steamed ray hydrolysate possessed significantly higher antioxidativeactivities than raw ray hydrolysates (p<0.05). The 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicalscavenging activity of steamed ray hydrolysate by pancreatin was slightly lower than raw ray hydrolysate at all concentrations.Raw ray hydrolysate displayed moderate hydroxyl radical scavenging activity, while steamed ray hydrolysate showed agreater increase in hydroxyl radical scavenging activity than raw ray hydrolysate at concentrations above 21.33mg/mL, and itreached 58.21% at 42.67mg/mL. The results of this study show that ray hydrolysates have potent free radical scavengingactivities and reducing power, and the steaming has a partial impact on the antioxidative activity of ray hydrolysates.
