Ingrid Undeland is professor in Food science. Her research deals primarily with ways of optimizing the use of marine raw materials (fish, shellfish, algae) through development of efficient quality preserving techniques, and through isolation of high value functional and/or bioactive compounds. Within the quality preservation area, a primary focus is lipid oxidation and how this destructive reaction is affected by pro- and antioxidants in the raw material/food product itself, as well as in the gastrointestinal tract. Within the isolation area, research is conducted for example on the so called pH-shift process and how it can be used to separate functional proteins from complex raw materials like by-products and seaweed. Recovered proteins are then evaluated from molecular, technofunctional and nutritional aspects.
