Model-based pre-processing in Raman spectroscopy of biological samples
Liland, Kristian Hovde; Kohler, Achim; Afseth, Nils Kristian (Journal article; Peer reviewed, 2016)Model-based pre-processing has become wide spread in spectroscopy and is the standard procedure in Fourier-transform infrared spectroscopy. It has also been shown to give valuable contributions in Raman spectroscopy. ... -

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) -
Prosessmålingsteknologi for proteinhydrolysater : FTIR-spektroskopi, SEC og OPA-metode
Ruud, Mari Linnéa (Master thesis, 2018)Enzymatisk proteinhydrolyse av restråstoff fra kjøtt-, fisk- og meierindustrien, med formål om å produsere spiselige peptidprodukter, er en voksende industri. For å kunne utnytte potensialet til disse proteinene er det ... -
Raman spectroscopy and NIR hyperspectral imaging for in-line estimation of fatty acid features in salmon fillets
Lintvedt, Tiril Aurora; Andersen, Petter Vejle; Afseth, Nils Kristian; Heia, Karsten; Lindberg, Stein-Kato; Wold, Jens Petter (Journal article; Peer reviewed, 2022)Raman spectroscopy was compared with near infrared (NIR) hyperspectral imaging for determination of fat composition (%EPA + DHA) in salmon fillets at short exposure times. Fillets were measured in movement for both methods. ... -
Raman spectroscopy for in-line food quality characterization
Lintvedt, Tiril Aurora (PhD Thesis;2023:5, Doctoral thesis, 2023)A major challenge in the food industry is to effectively handle massive streams of food raw materials and products of different origin and quality. In-line sensor systems for food analysis can potentially measure and ... -
The relationship between fatty acid profiles in milk identified by Fourier transform infrared spectroscopy and onset of luteal activity in Norwegian dairy cattle
Martin, Adam Dunstan; Afseth, Nils Kristian; Kohler, Achim; Randby, Åshild Taksdal; Eknæs, Margrete; Waldmann, Andres; Dørum, Guro; Måge, Ingrid; Reksen, Olav (Journal article; Peer reviewed, 2015)To investigate the feasibility of milk fatty acids as predictors of onset of luteal activity (OLA), 87 lactations taken from 73 healthy Norwegian Red cattle were surveyed over 2 winter housing seasons. The feasibility of ... -
The role of biospectroscopy and chemometrics as enabling technologies for upcycling of raw materials from the food industry
Måge, Ingrid; Wubshet, Sileshi Gizachew; Wold, Jens Petter; Solberg, Lars Erik; Böcker, Ulrike; Dankel, Elin Katinka; Lintvedt, Tiril Aurora; Kafle, Bijay; Cattaldo, Marco; Matić, Josipa; Sorokina, Liudmila; Afseth, Nils Kristian (Peer reviewed; Journal article, 2023)It is important to utilize the entire animal in meat and fish production to ensure sustainability. Rest raw materials, such as bones, heads, trimmings, and skin, contain essential nutrients that can be transformed into ... -
The use of Fourier‐transform infrared spectroscopy to characterize connective tissue components in skeletal muscle of Atlantic cod (Gadus morhua L.).
