1.Effect of environmental conditions on antioxidant activity of peptides
1. Effect of NaCl on antioxidant activity of peptides The peptides with the concentration of 3 mg/mL extracted from Jinhua ham were made up with either 2, 4, 6 and 8% (w/w) NaCl, maintained at 100 °C for 15 min, then cooled to room temperature in ice, and the DPPH radical scavenging activities and Fe2+-chelating abilities were measured. All determinations were performed with five replications.
