Biography Nils Kristian Afseth
My work as a PhD student covers the fields of spectroscopy, chemometrics and chemistry. The PhD research project wears the working title ”Spectroscopy for the rapid analysis of foods”, lies within the Matforsk project ”Effective assessment of food quality by rapid spectroscopic and sensor techniques”, and is performed under the strict supervision of Vegard Segtnan, Jens Petter Wold and Tomas Isaksson. The PhD research project serves several aims. I mainly work with spectroscopic techniques like Near-Infrared, Infrared and Raman spectroscopy and compare these techniques used as rapid and non-destructive methods for analysing interesting components of various kinds of food systems. In addition I try to combine various chemometric techniqueswith basic knowledge about the spectroscopic methods and the chemistry of the specific food systems to assure robust and quantitative descriptions of the components of interest. So far I have used quite a bit of time working with Raman spectroscopy. The theory of Raman scattering has been known for about 80 years, but not until recent years the Raman instruments have grown to be robust, less expensive and thus more available for both research and industry. The technique is rapid, the need for sample preparation is minimal, and molecular vibrations due to water do not dominate in Raman spectra like they often do in Near-Infrared and Infrared spectra. However, issues related to sensitivity and interfering physical features often provide cha

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.
1. July 2018 – 30. June 2021
The main goal in Smartbio is to develop novel process analytical technology, which will lead to new product innovations in the Enzymatic protein hydrolysis (EPH).
1. June 2018 – 31. May 2018
In Notably we will develop a new technological solution where processing of cod and chicken residual raw materials takes place in several different stages, so that the extracted components will be more valuable than they are today.
1. January 2016 – 31. December 2022
With the use of modern, research-based process technology and expertise, unused or under utilized biomass of marine or terrestrial origin can be used for new, marketable products. We coordinate, develop and increase Nofima’s total expertise related to the future of sustainable protein production. Peptek is a strategic research initiative focused on sustainability, total utilization, food safety and future food security.
