Academic & Professional Background

Jussi Loponen made his master degree and doctoral degree studies in the Cereal Technology Group of University of Helsinki. During the post-doctoral period he visited Michael Gänzle’s laboratory for one year in the University of Alberta, Canada. Currently, he is a University Lecturer in Food Technology and a Principal Investigator in Cereal Technology at the Department of Food and Environmental Sciences, University of Helsinki. Short academic education and professional career CV:

  • M.Sc. (Food Sciences, Cereal Technology), University of Helsinki 2002
  • Doctoral dissertation defence “Prolamin Degradation in Sourdoughs”, University of Helsinki 2006
  • D.Sc. (Food Sciences), University of Helsinki 2007
  • Academic visitor / Post-doctoral fellow, University of Alberta (Edmonton, Canada) 2007-2008
  • Post-doctoral researcher, University of Helsinki 2008-2009
  • Principal Investigator in Cereal Technology, University of Helsinki 2009→
  • University Lecturer in Food Technology, University of Helsinki 2010→

 

Research Summary

Jussi Loponen’s research focuses on the bioactivity and functionality of food proteins and especially on the modification of these by chemical and biochemical treatments, and food (bio)processing. The research, thus, aims to improve the bioactive and functional properties of food proteins such as immunoreactivity and interfacial behaviour. Sourdough fermentation among other acidification processes have this far been the major food bioprocesses applied. More specifically the research includes:

  • Elimination of immunogenic properties of gluten by food bioprocessing
  • Influence of gluten deamidation on its immunochemical properties
  • Targeted proteolysis of food proteins
  • Deamidation of cereal proteins for increased functionality
  • Foam and emulsion active proteins from oats
  • Macromolecular aspects on cereal food fermentations: polysaccharides and proteins
  • Advanced utilization of seed germination-induced enzymes in pH-dynamic food processing
  • Sourdough and other cereal food fermentations

 

Ongoing research projects:

  • MODPROT 2010-2012, Modification of the functionality and bioactivity of cereal proteins (Jussi is the Project Leader)
  • MANGLIN 2007-2011, Management of gluten intolerance:  novel insights in occurence, immunogenetics, food processing and safety. Jussi serves as the Principal Investigator in food processing part. Finnish Academy & Tekes jointly funded consortium project.
  • FOLAFIBRE 2007-2010, Aqueous processing of oats and barley:  In situ enhancement of folate and associated bioactive compounds while maintaining soluble dietary fibre physiologically active (Jussi is a part of Cereal Technology Group)
  • Contract research projects
