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, ... -
Feasibility of In-Line Raman Spectroscopy for Quality Assessment in Food Industry: How Fast Can We Go?
Lintvedt, Tiril Aurora; Andersen, Petter Vejle; Afseth, Nils Kristian; Marquardt, Brian; Gidskehaug, Lars; Wold, Jens Petter (Peer reviewed; Journal article, 2022)Raman spectroscopy is a viable tool within process analytical technologies due to recent technological advances. In this article, we evaluate the feasibility of Raman spectroscopy for in-line applications in the food ... -

Preprocessing Strategies for Sparse Infrared Spectroscopy: A Case Study on Cartilage Diagnostics
Tafintseva, Valeria; Lintvedt, Tiril Aurora; Solheim, Johanne Heitmann; Zimmermann, Boris; Rehman, Hafeez Ur; Virtanen, Vesa; Shaikh, Rubina; Nippolainen, Ervin; Afara, Isaac; Saarakkala, Simo; Rieppo, Lassi; Krebs, Patrick; Fomina, Polina; Mizaikoff, Boris; Kohler, Achim (Journal article; Peer reviewed, 2022)The aim of the study was to optimize preprocessing of sparse infrared spectral data. The sparse data were obtained by reducing broadband Fourier transform infrared attenuated total reflectance spectra of bovine and human ... -
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 (Peer reviewed; Journal article, 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. ... -
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 ...
