Fig. 3. Comparison of the 2,2-diphenyl-1-picrylhudrazyl (DPPH) 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,BUppercase letters indicate a significant difference in the DPPH radical scavenging activity based on breeds and within cuts before digestion (p < 0.05). A single asterisk indicates a significant difference in the DPPH radical scavenging activity before and after in vitro digestion (p < 0.05). JBP, Jeju black pigs; LYD, three-way crossbred pigs (Landrace × Yorkshire × Duroc).
