      Enzymatic protein hydrolysis can be used industrially for refining peptides from poultry by-products. The aim is to introduce these peptides for human consumption, but today the majority is used for feed or pet food. One ...

    • Fourier-transform infrared spectroscopy for monitoring proteolytic reactions using dry-films treated with trifluoroacetic acid 

      Kristoffersen, Kenneth Aase; van Amerongen, Aart; Böcker, Ulrike; Lindberg, Diana; Wubshet, Sileshi Gizachew; de Vogel-van den Bosch, Heleen; Horn, Svein Jarle; Afseth, Nils Kristian (Peer reviewed; Journal article, 2020)
      In this study we explore the potential of using Fourier-transform infrared (FTIR) spectra of trifluoroacetate-protein and peptide complexes for monitoring proteolytic reactions. The idea of treating dry-films of protein ...

    • Immobilized protease on magnetic particles for enzymatic protein hydrolysis of poultry by-products 

      Glomm, Wilhelm; Wubshet, Sileshi Gizachew; Lindberg, Diana; Dankel, Katinka R.; Afseth, Nils Kristian; Stenstad, Per Martin; Johnsen, Heidi (Peer reviewed; Journal article, 2021)
      Immobilization of enzymes onto magnetic particles can potentially allow for enzyme reuse, which can significantly reduce the cost associated with e.g. enzymatic protein hydrolysis (EPH) of fish and meat by-products. Here, ...

    • Improved estimation of in vitro protein digestibility of different foods using size exclusion chromatography 

      Rieder, Anne; Afseth, Nils Kristian; Böcker, Ulrike; Knutsen, Svein Halvor; Kirkhus, Bente; Mæhre, Hanne K; Ballance, Simon; Wubshet, Sileshi Gizachew (Peer reviewed; Journal article, 2021)
      While the harmonized INFOGEST model provides a physiologically relevant platform for simulated digestion, it needs to be combined with adequate analytical methods to enable quantification and comparison of protein digestibility ...
