This study investigated the emulsifying and antioxidant activity of 10 peptides derived from seaweed, methanotrophic
bacteria, and potatoes, which were identified as emulsifiers using quantitative proteomics and predictive
bioinformatics. The factors (e.g., interfacial properties, secondary structure, net charge) behind the dualfunctionality
of peptides were characterized and related to peptides’ ability to provide physical and oxidative
stability in 5 % fish oil-in-water emulsions during 10 days of storage. The secondary structure of some of the
peptides changed from highly disordered to more α-helical (GIIPATILEFLEGQLQEVDNNKDAR and GIIPGTILEFLEGQLQK)
or β-strand (VGFACSGSAQTYLSFEGDNTGRGEEEVAI, ELQVSARVTLEIEL, KVKINETVEIKGKFHV,
