Abstract The muscle of the prawn Penaeus japonicus was hydrolyzed by various proteases, and antioxidant activity of the hydrolysates was examined. Among the digests, pepsin digest showed the most potent antioxidant activity. Three antioxidant peptides have been isolated from the active peptidic fraction by ion-exchange chromatography, gel filtration, and ODS high-performance liquid chromatography. Their structures were identified as Ile-Lys-Lys, Phe-Lys-Lys, and Phe-Ile-Lys-Lys.
