In order to slow the spread of the coronavirus Sars-CoV-2 and the COVID-19 disease, our employees are currently working partly from home, partly in the laboratory. In case of urgent matters, please contact us via e-mail. Stay safe!



We focus on answering the following main research questions:

How do different factors (e.g., raw materials, industrial processing and microbial fermentation) influence structure, functionality and bioactivity within proteins as well as between proteins and other food components?


How do environmental factors influence the protein composition of crops and how can this knowledge be used to improve food security, food quality and food safety?


How do food proteins interact with the human gastrointestinal and immune systems and gut microbiota?


Why does the prevalence of food hypersensitivities, e.g., celiac disease or allergies, increase within the population?




Open positions

Our young and enthusiastic team is recruiting and we have open positions for PhD students, one to be filled as soon as possible, for the BMEL-funded project BigBaking (Link External Link) and one to be filled from October 01, 2020. If you are interested in breadmaking, proteins, peptides & proteomics, wheat and other cereals, this is the chance for you.

Become part of our team and apply now via e-mail to Prof. Dr. Katharina Scherf.

New paper in Frontiers in Plant Science

As a result of our successful collaboration over many years, our joint paper together with Eszter Schall, Zsuzsanna Bugyi, Kitti Török, Peter Koehler, Regine Schoenlechner and Sándor Tömösközi was just accepted today in Frontiers in Plant Science. We report our work entitled "Further steps towards the development of gluten reference materials – wheat flours or protein isolates?". The full text will be available soon here: doi: 10.3389/fpls.2020.00906 External Link



New book chapter in the Reference Module in Food Science

Our invited contribution entitled "Proteomics in Food Quality" in the Reference Module in Food Science is now available online. Dr. Sabrina Geisslitz and I provide an overview of proteomics techniques and definitions of food quality and discuss interesting applications of proteomics to study milk and dairy products, eggs, meat and cereals.

Heidi Strumpf starts as a secretary and will take care of all sorts of administrative tasks and support all of us as our competent contact person. Welcome to our group!

Nora Jahn and Alena Maric start their MSc theses on α-amylase/trypsin inhibitors and gluten detection. Welcome to our group!



New paper in Frontiers in Nutrition

Our collaborative paper from the Prolamin Working Group (PWG), namely Carlo Catassi, Fernando G. Chirdo, Paul J. Ciclitira, Conleth Feighery, Carmen Gianfrani, Frits Koning, Knut E. Lundin, Detlef Schuppan, Marinus J. Smulders, Olivier Tranquet, Riccardo Troncone and Peter Koehler, entitled "Recent progress and recommendations on celiac disease from the Working Group on Prolamin Analysis and Toxicity" was just accepted today in Frontiers in Nutrition. Based on the current state of knowledge, this perspective from the PWG members provides recommendations regarding clinical, analytical and legal aspects of celiac disease.

Dr. Sabrina Geißlitz starts as a research fellow in our group. Her research focuses on technofunctional, analytical and health-related aspects of ancient cereals such as spelt, emmer and einkorn. Welcome to our group!



Charlotte Stemler starts her PhD thesis on “Substrate specificities of baking lipases in fine bakery goods”. Welcome to our group!


New paper in Frontiers in Plant Science

Our review together with Thais O. Alves, Carolina T. S. D'Almeida and Mariana S. L. Ferreira entitled "Modern approaches in the identification and quantification of immunogenic peptides in cereals by LC-MS/MS" was just accepted today in Frontiers in Plant Science. We discuss the main proteomic techniques used in the identification and quantitation of gluten peptides related to celiac disease activity and wheat-related allergies. Read the full text here: doi: 10.3389/fpls.2019.01470 External Link

Katharina Scherf receives the Stockmeyer Wissenschaftspreis

On September 26, 2019, Katharina Scherf was awarded with the Science Award of the Heinrich-Stockmeyer-Foundation (Wissenschaftspreis der Heinrich-Stockmeyer-Stiftung) during the 59th Food Hygiene Workshop in Garmisch-Partenkirchen, DE. The award recognizes outstanding research projects in food sciences and is endowed with 5000 Euros. In accordance with the purposes of the Foundation, the award-winning projects offer practical solutions and application-oriented research to improve food safety and consumer protection as well as to strengthen consumer trust in food quality and safety. Scherf receives the prize for her habilitation thesis and, more specifically, for the development of a new test to detect gluten in cereal products that is already commercially available and more accurate than previously used methods.
