SAP1<MW<3kDa was chosen to investigate the improvement of antioxidant activity of peptides treated with pulsed electric field (PEF) technology. The effects of electric field intensity and pulse frequency on SAP1<MW<3kDa were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical inhibition, as well as the zeta potential and functional groups.
