Main odorants in barley tea identified
Mugicha (barley tea) is a popular drink in East Asia, which is traditionally prepared by brewing roasted barley grains with hot water. For the roasted barley tea, both hulled and hull-less (naked barley) varieties are used. Until now, little was known about the main odorants of barley tea, in particular it was not clear which compounds contribute to the difference in aroma between naked barley tea and tea made from hulled barley.
Under the leadership of the Leibniz-LSB@TUM, a German Japanese expert team has identified the main odorants in barley tea. Additionally, they demonstrated which compounds are responsible for the more intense smoky note of barley tea from hulled grains.
First comprehensive map of the proteome of the model plant Arabidopsis thaliana–A molecular map for the plant sciences
Plants are essential for life on earth. They provide food for essentially all organisms, oxygen for breathing, and they regulate the climate of the planet. Proteins play a key role in controlling all aspects of life including plants. Under the leadership of the Technical University of Munich (TUM), a team of scientists has now mapped around 18,000 of all the proteins found in the model plant Arabidopsis thaliana. Food chemist Andreas Dunkel of the Leibniz-LSB@TUM is one of the co-authors.

First evidence of rare amino acid in plants–Discovering what makes durian stink
Freising, February 28, 2020
Researchers at the Leibniz-Institute for Food Systems Biology at the Technical University of Munich (Leibniz-LSB@TUM) have confirmed the presence of the rare amino acid ethionine in a plant – or more precisely, in the fruit of the durian tree. Despite its pungent odor, durian is very popular in Southeast Asia. As the team of scientists has shown, the amino acid plays a key role in the formation of the characteristic durian odor.

Hop derivatives form a structurally independent group
Hop-derived compounds are renowned bioactive molecules and are considered as potential hit molecules for drug discovery to treat metabolic diseases. A chemoinformatics analysis revealed that hop-derived compounds cluster in a different region of the chemical space compared to known bitter food-derived compounds, pinpointing hop derived compounds as a very peculiar class of bitter compounds. You will find the study here.

News about the salt taste receptor
The molecular mechanisms that are decisive for attractive salt taste will probably remain a mystery for a while. Up to now, it has been thought that the canonical "epithelial sodium channel" formed by the three subunits alpha, beta and gamma could be the responsible salt taste receptor not only in rodents but also in humans. However, a new study on mice, in which Leibniz-LSB@TUM is significantly involved, casts doubt on this and suggests a different channel composition. You will find the study here
Food-Matrix potentially influences the effect of dietary fibres
High fibre consumption can have a positive effect on intestinal health, e.g. by increasing stool mass. As a new pilot study by the Technical University of Munich shows, as little as 10 g of insoluble wheat fibre can increase the amount of stool (wet weight) if it is integrated into the normal diet via solid foods every day. However, this effect did not occur when it is consumed by fibre-enriched drinks, at least in the current study. The research group, to which Andreas Dunkel from Leibniz-LSB@TUM belongs, therefore assumes that the food matrix could be decisive for the effect.

Tracing the function of olfactory receptors - or why copper can enhance onion odour
October 31, 2019
Humans possess hundreds of olfactory receptor types. But how do these receptors work at the molecular level? So far, only little is known about these receptors. Under the leadership of the Leibniz-LSB@TUM, a German-American team of scientists has shown for the first time that the OR2M3 olfactory receptor reacts up to four times more strongly to a sulphurous odour substance from onions in the presence of copper ions. Two newly discovered copper binding sites inside the receptor could be decisive for this.

On the trail of celiac disease triggers
Celiac disease is a chronic inflammatory bowel disease that has characteristics of an autoimmune disease. It is triggered by the consumption of gluten in genetically predisposed people. In addition to gluten, the body's own enzyme, tissue transglutaminase, plays a decisive role in the development of the disease. On the one hand, the enzyme changes the structure of the gluten fragments, which were formed during its digestion in the gut. On the other hand, it binds the gluten fragments firmly to itself. Scientists assume that these enzyme-gluten fragment complexes lead to the formation of autoantibodies. A recent Leibniz-LSB@TUM study provides new insights into the structure of these complexes. The findings could contribute to a better understanding of the role of the body's own enzyme in triggering celiac disease.
Funding: This research project (No. 250645717) was funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG, Bonn). The publication of this article was funded by the Open Access Fund of the Leibniz Association.
On the trail of bitter-tasting proteins
Fermented foods such as cheese or yoghurt contain numerous non-volatile substances that shape the taste profile of the respective food. These also include bitter-tasting fragments of long protein molecules that are formed during cheese ripening, for example. Researchers at the TU Munich and the Leibniz-LSB@TUM have now developed two new mass spectrometry-based analytical procedures which can be used to detect taste-active protein fragments in fermented foods in a very time-saving and comprehensive manner.
Funding: This research project (AiF 18124 N) by the Research Association of the German Food Industry (FEI) received funding from the “Otto von Guericke” Federation of Industrial Research Associations as part of the Industrial Collective Research program by the Federal Ministry for Economic Affairs and Energy pursuant to a parliamentary resolution by the German Bundestag.
Original wheat species are rich in protein
Original wheat species such as emmer, spelt and einkorn have a higher protein and gluten content than bread and durum wheat. In addition, the old species require less nitrogen fertilizer to produce the same protein yields as conventional wheat species. These are the findings of a new study in which scientists of the Leibniz-LSB@TUM were significantly involved. The new findings could contribute to breeding new cereal varieties with improved qualities for more sustainable agriculture.

The difference in scent between rice and wheat bread
People affected by coeliac disease must avoid bread containing gluten. They therefore often resort to gluten-free products such as rice bread. A new study has investigated which key odorants are responsible for odor differences between rice and wheat bread. It also shows which measures could be taken to optimise the aroma and thus also the quality of rice bread. Researchers of the Leibniz-LSB@TUM played a leading role in the study.

For the future we wish her all the best and continued success for her career!
Better food quality control‒Food profilers develop new methodological approach for food analysis
Freising, July 30, 2019
Scientists at the Technical University of Munich (TUM) and the Leibniz-Institute for Food Systems Biology have developed a new methodology for the simultaneous analysis of odorants and tastants. It could simplify and accelerate the quality control of food in the future.
New gluten test is reliable
Under the leadership of PD Dr. Katharina Scherf from Leibniz-LSB@TUM, 19 laboratories from all over the world have tested whether a new gluten test lives up to its promise. The new gluten ELISA test kit is the first to use four different antibodies simultaneously. As the researchers show, the test is able to detect gluten contaminations in oats and oat products derived from wheat, rye and barley. This is a decisive advantage over the antibody-based tests previously used, which only detect a specific gluten fraction (prolamins).
The new test kit (RIDASCREEN® Total Gluten, R7041) is a result of the BMBF-funded joint project "Fluorescence optical rapid test system for the sensitive detection of gluten (GLUTEVIS)".

Nitrogen fertilization influences the baking quality of wheat flour–Less is sometimes more
An international team of scientists has investigated the extent to which late nitrogen leaf fertilisation of wheat can contribute to an improved baking quality of wheat flour. As the new study shows, late fertilisation only optimises the baking quality if the plants had a low nitrogen uptake due to unfavourable environmental conditions. In particular, fertilization with 100 kg nitrogen per hectare led to an optimal protein composition in the wheat grain and thus achieved a high baking quality of the flour. The Leibniz-LSB@TUM was also involved in the study.

Optimizing fresh cheese production
A team of scientists led by the University of Hohenheim has now refined a new method for the production of fresh cheese. Microfiltration makes it possible to produce fresh cheese in such a way that it tastes less bitter and that sweet whey is produced as a by-product that can be easily processed. The decisive factor is that the calcium-protein ratio of the milk retentate is decreased to ≤ 15.9 mg/g prior to fermentation. Researchers from Leibniz-LSB@TUM and TU Munich were also involved in the project.

News about gluten and wheat allergy
WDEIA (wheat-dependent exercise-induced anaphylaxis) is a rare form of wheat allergy. Physical activity, alcohol or certain medications are suspected of increasing the absorption of gluten components (gliadins) from the intestine into the blood and thus triggering the allergy. As a new study shows, the blood levels of gliadins are independent of the named factors ̶ at least in healthy persons. Neither did the researchers observe a correlation between gliadin levels and zonulin, a marker for the permeability of the intestinal barrier. The Leibniz-LSB@TUM was significantly involved in the study.

Beyond the flavour – Chemoreceptors offer approaches for the development of new drug therapies
Odour and taste receptors are not only found in nose or mouth. Recent studies indicate that they also take on other functions in the body, for example in the immune system or the regulation of metabolism. Therefore, they could serve as starting points for the computational development of new therapeutics. A new review article of the Leibniz-LSB@TUM summarises the current data on this topic.
Funding: This work was supported by the TUM in the framework of the Open Access Publishing Program.
Determining the benzene content of foods safely
Benzene is carcinogenic. For this purpose, it is important to accurately determine the benzene content in flavoured foods, such as cherry-flavoured drinks.

Bioelectronic tongue developed for bitter compounds
An international research team, including the Leibniz-LSB@TUM, has developed a cell-based “bioelectronics tongue”. It is used to specifically identify bitter substances containing a thiourea or isothiocyanate group. Previous studies suggest that some of these compounds are anti-cancerogenic. The new test system could therefore be used both in future food and pharmaceutical studies.

Wheat proteins and immune system
Wheat is an important nutrient source, which also contributes to our protein supply. However, gluten and non-gluten proteins have been identified as allergens or triggers of celiac disease. A new article by the Leibniz-LSB@TUM now provides an overview about wheat proteins and the immune system.
Funding: This work was supported by the Leibniz Association within the Leibniz Competition 2016 (project WHEATSCAN, K195/2015).
What are taste receptors doing in the brain?
Taste receptors are not just for tasting. They are also found on cells of organs that are involved in the hormonal regulation of the body. These include the brain, the pancreas or the thyroid gland. A new review article of the Leibniz-LSB@TUM summarizes what scientists have discovered so far about possible functions of taste receptors in the (neuro)endocrine system.
Rapeseed doesn't just contain oil but high-quality protein, too. However, protein extracts from rapeseed have an intense, bitter off-taste. A team led by food chemist Thomas Hofmann has now identified the substance that is pivotal for the bitter taste. This is a first step towards developing rapeseed for the human protein supply.
Food chemist has been awarded the scientific prize of the Verband Deutscher Großbäckereien
On January 17, 2019, Kathrin Schalk has been awarded the scientific prize of the Verband Deutscher Großbäckereien at the 48th Wissenschaftlichen Informationstagung der Berlin-Brandenburgischen Gesellschaft für Getreideforschung e.V. in Berlin. The award honors her outstanding dissertation entitled "Development of targeted mass spectrometric methods for the quantification of gluten-specific peptides in foods".
A new study by the Leibniz-Institute for Food Systems Biology at the Technical University of Munich (Leibniz-LSB@TUM) shows that craft beer should be kept cool and consumed as fresh as possible. After three months, cold stored beer already loses more than one third of an important hop odorant which characterizes the typical aroma of many craft beers. Storage at room temperature causes the concentration of this substance to decrease even more significantly.
Martin Steinhaus and Klaas Reglitz from the Leibniz LSB@TUM recently published their findings in the journal BrewingScience, doi.org/10.23763/BRSC18-13STEINHAUS.
Life sciences for the senses
November 15, 2018
PD Dr. Dietmar Krautwurst presented some of his latest research findings at the 16th journalist workshop of the Promega GmbH. He heads section II of the Leibniz-LSB@TUM. Amongst others, he and his team investigate the function of olfactory receptors, which are not only found in the nose, but also on cells of the immune system (leukocytes).
Why einkorn could be better for people with wheat intolerance
Modern, but also original types of wheat naturally contain a group of proteins, which might cause symptoms of wheat intolerance. A new study by the Leibniz-Institute for Food Systems Biology at the Technical University of Munich shows for the first time that in comparison to common wheat, spelled and emmer, einkorn contains no or significantly lower amounts of these proteins. Researchers have now published their findings in the Journal of Agricultural and Food Chemistry.

Thomas Hofmann elected as TUM’s new President
Freising October 17, 2018
The Board of Trustees of the Technical University of Munich (TUM) has elected Prof. Thomas Hofmann (50) as the new President of TUM. The experienced university manager has held the position of Senior Vice President Research and Innovation at TUM since 2009. He made a significant contribution to TUM’s success in the Excellence Initiative, especially in developing the internationally acclaimed “TUM Faculty Tenure Track” recruitment and career system. Under his guidance, TUM also became Germany’s top university for the establishment of start-ups. The holder of the Chair of Food Chemistry and Molecular Sensory Science has received multiple awards for his research and teaching. On October 1, 2019, Hofmann will take over from Prof. Wolfgang A. Herrmann, whose far-reaching reforms in his 23-year tenure saw TUM rise to international top level.
New gluten test on the test bench
For the first time a gluten ELISA test uses four different antibodies simultaneously. Thus, it is able to detect gluten fractions from wheat, rye and barley that contaminate oats and oat products. This is a decisive advantage over previously used antibody-based assays. Over the past three weeks, 19 laboratories from around the world led by Dr. Katharina Scherf from the Leibniz-LSB@TUM have analysed whether the test kit indeed determines reliably gluten contaminations in oats and oat products. The results will be available shortly.
The new test kit (RIDASCREEN® Total Gluten, R7041) is a result of the BMBF-funded joint project "Fluoreszenzoptisches Schnelltestsystem für den sensitiven Nachweis von Gluten (GLUTEVIS)".
Bitterless cough syrup
An international team of scientists has developed a set of bitterless prodrugs for a bitter tasting expectorant. In the future these prodrugs could contribute to reduce the bitterness of well-tried cough syrups, as they do not activate the bitter taste receptor TAS2R14 on the tongue. The substances are stable at neutral pH. Only gastric acid converts them into the active, bitter-tasting expectorant guaifenesin. Toddlers in particular often reject bitter medicine and would benefit from bitterless cough syrup.
Researchers from the Leibniz-LSB@TUM were also involved in the cooperation project.

enable 2.0: Risk markers for childhood obesity
Obesity in children is a serious public health problem. Affected children usually carry over extra pounds into adulthood. Obesity in general increases the risk of cardiovascular diseases, diabetes and certain types of cancer. In order to prevent this fatal development, it will be necessary to identify children at-risk as early as possible.
enable is one of four clusters about nutrition research funded by the Federal Ministry of Education and Research (BMBF). Both the Leibniz-LSB@TUM as well as the Chair of Food Chemistry and Molecular Sensory Science at TUM are involved in the joint project–each of them with an own subproject. In order to develop new nutritional strategies against childhood obesity, both institutions work together with the Dr. von Haunerschen Children's Hospital of the LMU. Their goal is to identify biomarkers that can help to detect highly vulnerable children already at babyhood.
Participating researchers at the Leibniz-LSB@TUM: Prof. Thomas Hofmann, PD Dr. Dietmar Krautwurst, Dr. Patrick Marcinek and Andreas Dunkel.

Strategies for the discovery of novel aroma-active key compounds in foods
New AiF project launched: "Heat makes the difference: fruit juices in comparison"
There are different methods to preserve juices. In addition to classic heat pasteurization, there are also gentle manufacturing processes in which the relatively high thermal load of the products is eliminated. This helps to preserve the natural aroma, the fresh taste and a high content of secondary plant compounds in the juice.
The quality of the juice has changed dramatically after classical pasteurisation. Nevertheless, the market often offers products labelled as carefully manufactured that are based on heat-pasteurized juices. Frequently, such juices are sold at the same price as completely carefully produced, high-quality direct juices. This is a disadvantageous for both consumers and manufacturers of high quality products. However, so far no simple but precise detection methods exist to prove such misrepresentation.
The aim of the new research project is to develop suitable detection methods to identify false marketing of direct juices. Apart from PD Dr. Martin Steinhaus and Eva Bauersachs from Leibniz-LSB@TUM, Prof. Andreas Schieber's team from the University of Bonn is involved in the cooperation project.
The project is funded by the Forschungsvereinigung Forschungskreis der Ernährungsindustrie e.V. (FEI) and the Arbeitsgemeinschaft industrieller Forschungsvereinigungen „Otto von Guericke“ e.V. (AiF) via the Federal Ministry for Economic Affairs and Energy. Read more...
Food ingredient with potential side effects
Tyramine is a natural, bioactive substance that we ingest via various foods. In particular certain cheeses such as Roquefort or soy sauce may contain larger quantities. Excessive intake or simultaneous use of certain medications may cause toxic effects, extreme hypertension, pseudoallergic reactions, and migraine.
Scientists of the Leibniz LSB@TUM have now compiled quantitative data on the tyramine content of more than 100 foods in a review article. In addition, they describe the factors that influence the concentration of the biogenic amine, as well as the molecular targets through which tyramine exerts its effects in the human body.
Flour quick test improved
New results of a comparative study between ancient and modern wheat species make it now possible to predict the baking quality of spelled, emmer and einkorn wholemeal flour quickly and reliably.

Bitter taste receptor in the gut acts anti-diabetic
The synthetic analogue of isohumulone, the hop-derived bitter principle in beer, mediates its anti-diabetic action via a bitter taste receptor in the gastrointestinal tract – as shown in mice. Thus, targeting extraoral bitter taste receptors may be useful in metabolic disease treatment.
This is a result of an international cooperation project of the Scripps Research Institute in La Jolla, USA, in which Dr. Maik Behrens from the Leibniz-LSB@TUM is also involved. Read more...

"Milestone" wheat gene map could help food security and allergies
Scientists have mapped out more than 94% of the genome of Chinese Spring bread wheat — adding that by manipulating its genetic code, people could eventually improve global food security and possibly alleviate some immune disorders like celiac disease or wheat allergies.
"[This] is a true milestone in wheat research. This is the foundation for future breeding strategies that will help develop improved wheat cultivars that are resistant to climate change, pests and pathogens while providing good agricultural performance in terms of yield and nutrient density“, comments Katharina Scherf of the Leibniz-LSB@TUM.

Comparison of Gluten Test Kits
Gluten contained in cereals such as wheat can cause celiac disease in hereditary predisposed people. Therefore, reliable analytical methods are needed to ascertain that gluten-free products contain less than 20 mg/kg gluten. A team around Dr. Katharina Scherf from the Leibniz-LSB@TUM has now compared the reliability of different immunological test kits for gluten. As study results show, there are some major differences between the kits, especially in the detection of gluten from spelt, durum wheat, emmer and einkorn. The study results indicate that there is still a demand for optimizing gluten test kits.

Research for healthy and delicious nutrition
It all began humbly in 1918 with the immediate goal of practically investigating how to improve nutrition in times of war-related food shortages. Today it is a major player in research on food and nutrition. The State of Bavaria has paved the way for this journey to the future: The Leibniz-Institute for Food Systems Biology at the Technical University of Munich is celebrating its 100th anniversary with a festive scientific symposium including high-ranking representatives from science, politics and the community.
June 14, 2018: New AiF project "Activity of amylase trypsin inhibitors" is launched
Amylase trypsin inhibitors are enzymes that are naturally present in gluten-containing cereals such as wheat and thus also in pastry products. Recent research results of the team around Prof. Dr. Dr. Detlef Schuppan of the Institute of Translational Immunology of the Mainz University Medical Center point out that it is not primarily gluten but enzymes that are responsible for the non-celiac wheat sensitivity. The symptoms of this disease occur mainly extraintestinal. These include drowsiness, fatigue, joint and muscle pain, skin changes and depressive moods. Likewise, existing chronic diseases can worsen. Schuppan estimates that in some people, the enzymes activate the innate immune system in the small intestine. In its activated state, it releases inflammation-promoting substances that might be responsible for the complaints of affected persons. Since the immune response is purely dose-dependent, it is sufficient, according to the scientists, to reduce enzyme uptake by about 80-95 percent in order to prevent the onset of symptoms. However, it is still unclear how the enzyme concentrations and activities in cereal products such as bread correlate with each other, or how much they are influenced by different manufacturing processes or the types of cereals that are used.
Sabrina Geißlitz and project leader Dr. Katharina Scherf from the Leibniz-LSB@TUM work closely together with Schuppan’s team to clarify these points. Their aim is to develop sensitive and reliable detection methods for service laboratories, which allow optimization of the manufacturing processes of bread and pastry leading to minimal enzyme content in the products. The result would be well-controlled bakery products that are more digestible for patients suffering from wheat sensitivity or irritable bowel syndrome.
The Project is funded by: Forschungsvereinigung Forschungskreis der Ernährungsindustrie e.V. (FEI) and by Arbeitsgemeinschaft industrieller Forschungsvereinigungen „Otto von Guericke“ e.V. (AiF) via the Federal Ministry for Economic Affairs and Energy.
June 9, 2018: Long Night of Sciences in Berlin
From 5 to 12 pm, at the Long Night of Sciences in Berlin, scientists of the Leibniz-LSB@TUM presented their research together with partners from the Leibniz Research Alliance "Sustainable Food Production and Healthy Nutrition" at the Headquarter of the Leibniz Association. At the booth of the Leibniz-LSB@TUM it was all about the questions: Is gluten generally harmful to health? Is spelt easier to digest than wheat? Are old wheat varieties better than new ones? Questions that the Leibniz-LSB@TUM scientists, together with colleagues from the Leibniz Institute of Plant Genetics and Crop Plant Research in Gatersleben are pursuing together in the "Wheatscan" project.
Cover Story: Leibniz-LSB@TUM Publication in the Journal of Agricultural and Food Chemistry
Dr. Katharina Scherf leads the team 'Functional Biopolymer Chemistry' at the Leibniz-LSB@TUM. Together with her peers, she discovered a new method to detect gluten. The scientists introduced this method in the April edition of the Journal of Agricultural and Food Chemistry. In susceptible people, even small amounts of gluten in their food may cause an inflammatory bowel disease known as celiac disease. Therefore, knowing whether grain products contain gluten and how much of it is present is crucial for everybody who is gluten-sensitive.
In the new method, the scientists couple liquid chromatography and mass spectrometry in a tandem procedure. This allows the quantitative analysis of even very small amounts of gluten in barley, rye and oat products. While previously available methods only provided data on the content of a specific gluten fraction (the prolamin fraction), the new method has the advantage of allowing the determination of the total gluten content.
