Emulsifying peptides from potato protein predicted by bioinformatics: Stabilization of fish oil-in-water emulsions

This work investigated the use of bioinformatics to predict emulsifying peptides embedded in patatin proteins from potato (Solanum tuberosum). Six peptides (23–29 amino acids) with potentially different predominant structure at the oil/water interface (e.g. α-helix, β-strand or unordered) were identified within patatin sequences. The interfacial tension between peptides solutions and fish oil as well as the physical and oxidative stability of 5...
