Biography Åge Oterhals

I am employed as a senior scientist in Nofima. My main interests are within marine and industrial biotechnology, feed technology, process optimization and effect of process conditions on product quality. Present research activities include physicochemical characterization of protein ingredients related to extruded fish feed production, protein hydrolysis, process development and application of separation technology. I have a civil engineer degree (M.Sc.) in chemistry and industrial biotechnology and a PhD degree in physics and technology. Former research activities include industry and process related projects within raw material quality, separation and dewatering technology, feed technology, fermentation technology, fish oil refining and f
ood applications, and removal of persistent organic pollutants in fishmeal and fish oil. I have former industrial experience in development and formulation of specialty diets, food supplements, functional foods, feed ingredients and feeds.
