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

Digital Food Quality (short named DigiFoods) is a centre for research-based innovation (SFI) with the purpose of developing smart sensor solutions for food quality assessment directly in the processing lines, throughout the food value chains. The obtained food quality information will be used for optimization of both processes and value chains and make the food industry more efficient and sustainable.

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.
