New paper in Scientific Reports
The ancient wheat species einkorn, emmer and spelt are cultivated in very low amounts compared to the modern wheat species e.g. common (bread) wheat. Some consumer report that they feel more comfortable with ancient wheat species and that they have less symptoms typical for wheat sensitivity and other intestinal disorders. One hypothesis was that the contents of amylase/trypsin-inhibitors (ATIs) increased during the development of modern wheat species. We showed by quantitation of 13 ATIs by LC-MS/MS that the ancient spelt had higher ATIs contents that common wheat independently of three growing locations.

New papers in Journal of Agricultural and Food Chemistry and Cereal Chemistry
Epidemiologic studies suggest an increasing prevalence of celiac disease and nonceliac gluten/wheat sensitivity. One hypothesis is that wheat breeding over the course of the last century might have caused changes in the composition of wheat proteins. To verify or falsify this hypothesis, we investigated agronomic and proteomic characteristics of a well-defined sample set comprising the 60 most widely grown winter wheat cultivars in Germany from 1891 to 2010 grown in three consecutive harvest years together with Hans Weber and Andreas Börner from the Leibniz-Institute for Plant Genetics and Crop Plant Research (IPK) in Gatersleben, Germany. At protein level, we found no evidence to support an increased immunostimulatory potential of modern wheats compared to old wheat. A new data evaluation approach allowed us to map the protein fingerprints of the different cultivars in greater detail and to identify exceptional samples.

Our book "Wheat - An Exceptional Crop: Botanical Features, Chemistry, Utilization, Nutritional and Health Aspects" is available now. We discuss the benefits of wheat from a wheat science, nutrition and technology perspective and provide an overview of adverse reactions to wheat. Find out more here: ISBN 9780128217153
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
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.

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.
