• Preprocessing strategies for infrared spectral data with limited numbers of spectral channels 

      Lintvedt, Tiril Aurora (Master thesis, 2019)
      Joint health is vital for mobility and well being of all people. In an EU project called Miracle, a mid-infrared arthroscopic probe for diagnosis of joint diseases during surgery is being developed. The focus is mid infrared ...
    • 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 (Peer reviewed; Journal article, 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 (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 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 ...
