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 ... -
Facilitated identification of bioactive peptide fractions and optimization of enzymatic protein hydrolysis using size-exclusion chromatography fingerprints: Combining interval PLS and response surface modeling
Matić, Josipa; Børilden, Ben; Sorokina, Liudmila; Rønning, Sissel Beate; Kristoffersen, Kenneth Aase; Afseth, Nils Kristian; Wubshet, Sileshi Gizachew (Journal article; Peer reviewed, 2025)Protein hydrolysates made from food industry byproducts have the potential to be used as nutraceuticals that can alleviate high blood pressure, by inhibiting angiotensin converting enzyme I (ACE-I). Discovery and optimization ... -
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 ... -
