Average molecular weight, degree of hydrolysis and dry-film FTIR fingerprint of milk protein hydrolysates: Intercorrelation and application in process monitoring.
Kristoffersen, Kenneth Aase; Afseth, Nils Kristian; Böcker, Ulrike; Lindberg, Diana; Wubshet, Sileshi Gizachhew; de Vogel-vanden Bosch, Heleen; Ruud, Mari Linnea (Peer reviewed; Journal article, 2020)Fourier-transform infrared (FTIR) spectroscopy was applied to predict the degree of hydrolysis (DH%) and weight-average molecular weight (Mw) in milk protein hydrolysates. Both DH% and Mw are important quality parameters ... -
Effects of poultry raw material variation and choice of protease on protein hydrolysate quality
Lindberg, Diana; Kristoffersen, Kenneth Aase; de Vogel-van den Bosch, Heleen; Wubshet, Sileshi Gizachew; Böcker, Ulrike; Rieder, Anne; Fricke, Enno; Afseth, Nils Kristian (Peer reviewed; Journal article, 2021)The aim of this study was to investigate the role of compositional variations in side-streams from the chicken and turkey industry on product characteristics after enzymatic protein hydrolysis (EPH). Variation was obtained ... -
Environmental factors associated with glutenin polymer assembly during grain maturation
Koga, Shiori; Aamot, Heidi Udnes; Uhlen, Anne Kjersti; Seehusen, Till; Veiseth-Kent, Eva; Hofgaard, Ingerd Skow; Moldestad, Anette; Böcker, Ulrike (Journal article; Peer reviewed, 2020)This study aims to understand the environmental factors, focusing on rain and fungal infection, affecting the assembly of glutenin polymers during grain maturation. Spring wheat was grown in the field and grains were sampled ... -
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 ... -
FTIR-based hierarchical modeling for prediction of average molecular weights of protein hydrolysates
Kristoffersen, Kenneth Aase; Liland, Kristian Hovde; Böcker, Ulrike; Wubshet, Sileshi Gizachhew; Lindberg, Diana; Horn, Svein Jarle; Afseth, Nils Kristian (Journal article; Peer reviewed, 2019)In the presented study, Fourier-transform infrared (FTIR) spectroscopy is used to predict the average molecular weight of protein hydrolysates produced from protein-rich by-products from food industry using commercial ... -

Microdochium majus and other fungal pathogens associated with reduced gluten quality in wheat grain
Aamot, Heidi Udnes; Lysøe, Erik; Koga, Shiori; Nielsen, Katherine Ann Gredvig; Böcker, Ulrike; Brodal, Guro; Dill-Macky, Ruth; Uhlen, Anne Kjersti; Hofgaard, Ingerd Skow (Peer reviewed; Journal article, 2020)The bread-making quality of wheat depends on the viscoelastic properties of the dough in which gluten proteins play an important role. The quality of gluten proteins is influenced by the genetics of the different wheat ... -
Monitoring Secondary Structural Changes in Salted and Smoked Salmon Muscle Myofiber Proteins by FT-IR Microspectroscopy
Carton, Izaskun; Böcker, Ulrike; Ofstad, Ragni; Sørheim, Oddvin; Kohler, Achim (Journal article; Peer reviewed, 2009)Fourier transform infrared (FT-IR) microspectroscopy and light microscopy were used to study changes in the myofibrillar proteins and microstructure in salmon muscle due to dry salting and smoking. Light microscopy showed ... -
Polymerisation of gluten proteins in developing wheat grain as affected by desiccation
Koga, Shiori; Böcker, Ulrike; Wieser, H; Koehler, P; Uhlen, Anne Kjersti; Moldestad, Anette Aamodt (Journal article; Peer reviewed, 2017)The breadmaking quality of wheat is affected by the composition of gluten proteins and the polymerisation of subunits that are synthesised and accumulated in developing wheat grain. The biological mechanisms and time course ... -
