Preparation of sesame peptide and evaluation of antibacterial activity on typical pathogens

► Preparation of sesame protein hydrolysate in enzyme membrane reactor. ► Fractionation of protein hydrolysate by ultrafiltration to obtain potential peptide fraction. ► Characterization of potent peptide fraction by mass spectra and amino acid composition. ► Assessment of antibacterial activity of sesame peptide fractions on two common pathogens.
