Biography Jens Petter Wold
COMPETENCE My main competence is within applied biospectroscopy and rapid quality assessment of foods. My interests cover front face fluorescence, NIR and Raman spectroscopy. I do also have some experience with spectral imaging, which is a very fascinating and powerful technique. To work efficiently with analysis of spectra from very complex biomaterials, multivariate modelling (chemometrics) is a necessity! I have strong interests in these statistical methods, but at a practical level – they are useful tools. Central applications in my work: · Measurement of auto-oxidation and photo-oxidation in meat, fish and dairy products by fluorescence spectroscopy. · On-line measurement of fat, water, protein, colour and colour defects by NIR andVIS spectroscopy and imaging · Determination of connective tissue in meat and fish by fluorescence spectroscopy · Raman spectroscopy on biomaterials – how to cope with background fluorescence At our institute I am a principal researcher and project manager for one of ten basic research projects: Effective assessment of food quality by rapid spectroscopic and sensor techniques (Strategic institute project). I also mange several R&D projects for the Norwegian Research Council and different Norwegian companies, primarily connected to feed and foods. Water distribution in whole dried salted cod based on on-line imaging NIR system. Multivariate curve resolution (based on PARAFAC) to resolve pure spectra of porphyrins and chlorophylls

1. November 2020 – 31. October 2028
Digital Food Quality (short named DigiFoods) is a centre for research-based innovation (SFI) with the purpose of developing digital solutions for food quality assessment with cutting edge technology. New sensor systems will radically transform food production industry into a more efficient and sustainable industry.

Over almost 40 years, Nofima has built up a strong scientific community in the field of spectroscopy - rapid and non-destructive measurements for process optimization. We possess solid expertise within an international format and a modern instrument platform, which is unique in Norway and comparable to the best in Europe. We wish to develop this further by means of establishing the strategic research initiative Spectec.
