Purification and Identification of Novel Xanthine Oxidase Inhibitory Peptides Derived from Round Scad (<i>Decapterus maruadsi</i>) Protein Hydrolysates

Abstract

The objective of the present study was to investigate the xanthine oxidase (XO) inhibitory effects of peptides purified and identified from round scad (Decapterus maruadsi) hydrolysates (RSHs). In this study, RSHs were obtained by using three proteases (neutrase, protamex and alcalase). Among them, the RSHs of 6-h hydrolysis by neutrase displayed the strongest XO inhibitory activity and had an abundance of small peptides (914 (contained in the XO) in the XO inhibitory activity of the peptides.
