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 ... -
Expanding the analytical toolbox for characterization of proteolytic reactions : advances in FTIR spectroscopy and classical methods
Kristoffersen, Kenneth Aase (PhD Thesis;2019:85, Doctoral thesis, 2019)Enzymatic protein hydrolysis is a well-established industrial process recognized for its potential to improve sustainability in food production by valorization of protein-rich byproducts from the food industry. Monitoring ... -
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 ... -
Pretreatment of different food rest materials for bioconversion into fungal lipid-rich biomass
Tzimorotas, Dimitrios; Afseth, Nils Kristian; Lindberg, Diana; Kjørlaug, Oda Marie; Axelsson, Lars Torsten; Shapaval, Volha (Journal article; Peer reviewed, 2018) -
The perceived taste of lactic acid fermentation in protein hydrolysates : a screening of the sensory properties of lactic acid bacteria (LAB) implemented in hydrolysate products produced with co-products from the food industry (poultry-, fish- and dairy)
Rein, Magnus (Master thesis, 2018)The use of enzymatic protein hydrolysis is today common practise within the food industry to extract additional high quality nutritional components, however the method is rather limitedly used towards products for later ...
