In this study, Sargassum coreanum was enzymatically hydrolyzed to prepare water-soluble extracts by using five carbohydrates (Viscozyme, Celluclast, AMG, Termamyl and Ultraflo) and five proteases (Protamex, Kojizyme, Neutrase, Flavozyme and Alcalase) and their potential antioxidant activity were evaluated. The Celluclast and Neutrase extracts of Sargassum coreanum exhibited better DPPH radical scavenging activities (92.42% and 92.78%, respectively) and hydrogen peroxide ($H_2O_2$) scavenging activities (58.28% and 57.97%, respectively) compared to those of other enzymatic extracts. These results suggest that Sargassum coreanum would be a good raw materials for antioxidant and enzymatic hydrolysis would be a good strategy to prepare antioxidant extracts from seaweeds.
