My research concern food technologies and effects on food components and their properties, including protein modification and stability in relation to functionality and product development. Focus is on how processing methods and non-thermal technologies, especially high hydrostatic pressure, affects molecules in relation to structural changes and chemical reactions from molecular size to macroscopic levels based on molecular and mechanistic understanding to support practical functional food design. In addition, to assess the nutritional benefits of processing of food materials, thus the assessment of the in vitro protein digestibility (IVPD) of raw materials and plant-based products after processing, e.g. extrusion, high pressure and fermentation, like meat analogues, and relationship with protein functionality. Thereby, clarify concepts and opportunity on how to increase the digestion potential of raw (protein) plant materials and the processed materials and products. I am interested in supporting a true sustainable food production, which is based on an evaluation of raw material, production, consumption and protein utilization.

  • Food chemistry and physics in relation to food processing and storage
  • Thermodynamics in food
  • High pressure methods for food processing and effects on food components and their properties
  • High pressure induced protein changes in meat, milk and plant products with focus on texture and protein digestibility
  • Development of new foods by different processing methods including non-thermal processing technologies
