Calanus finmarchicus as a novel source of health-promoting bioactive peptides: Enzymatic protein hydrolysis, characterization, and in vitro bioactivity
Matic, Josipa; Bøgwald, Isak; Tengstrand, Erik; Rønning, Sissel Beate; Afseth, Nils Kristian; Wubshet, Sileshi Gizachew (Peer reviewed; Journal article, 2023)Calanus finmarchicus is a crustacean currently used as a source of marine lipid. The lipids are extracted by enzymatic protein hydrolysis, while the remaining peptide fraction is regarded as a byproduct. In the present ... -
Calibration transfer between different spectrometers by wavelength correspondence
Tengstrand, Erik; Solberg, Lars Erik; Dankel, Elin Katinka; Lintvedt, Tiril Aurora; Afseth, Nils Kristian; Wold, Jens Petter (Peer reviewed; Journal article, 2024)In this paper we present a method for transferring calibrations between different spectrometers based on assigning wavelength correspondence. It has been tested for near-infrared (NIR) and Raman spectroscopic instruments, ... -
