Pepsin Digested Oat Bran Proteins: Separation, Antioxidant Activity, and Identification of New Peptides

Figure 3

Superoxide (a) and hydroxyl (b) radical scavenging activities of oat protein hydrolysate (OPH) hydrolyzed for 2 h with pepsin 1 : 30 E/S ratio and its RP-HPLC fractions (F2–F8). GSH: glutathione (control). Bars with different letters on the same graph are significantly different in the Fisher LSD test (, ). Data are means ± standard deviations.
