Fig. 2. Comparison of the 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity between (A) the loin peptide extracts from JBP and LYD, (B) the ham peptide extracts from JBP and LYD, (C) the loin and ham peptide extracts from JBP, and (D) the loin and ham peptide extracts from LYD.

Data are presented as mean ± standard deviation. ^a,bLowercase letters indicate a significant difference in the ABTS radical scavenging activity based on breeds and within cuts after digestion (p < 0.05). A single asterisk indicates a significant difference in the ABTS radical scavenging activity before and after in vitro digestion (p < 0.05). JBP, Jeju black pigs; LYD, three-way crossbred pigs (Landrace × Yorkshire × Duroc).
