Purification and characterization of foxtail millet-derived peptides with antioxidant and antimicrobial activities

In this study, we describe the purification by RP-HPLC and amino acid sequencing by LC-MS of peptides derived from foxtail millet (Setaria italica) meal fermented by Lactobacillus paracasei Fn032. The purified foxtail millet peptide fractions (FFMp) of Tyrosine/Leucine-rich (FFMp4=756.84, FFMp6=678....
