High-tech methods for detecting microplastics in food and suitable prevention measures are the focus of the joint German-Austrian Cornet project "MicroplasticATfood", which kicked off on 1 July 2021. With its expertise in microplastic research, the University of Bayreuth is involved in interdisciplinary case studies dealing with packaging, filling lines, beverages, surfaces of solid food, and soluble foods. On the German side, the project will be funded by the Federal Ministry for Economic Affairs and Energy until 2023 to the tune of € 542,000, of which about € 275,000 have been allocated to the University of Bayreuth.
A team of scientists from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has now discovered that the odorant receptor OR5K1 is specialized to recognize pyrazines in both humans and domesticated animals. These are volatile substances that contribute to the typical odor of many vegetables or are formed when food is heated. In addition, pyrazines also play a role as signaling substances in intra- or interspecific communication. The new research results contribute to a better understanding of the molecular mechanisms underlying the odor perception of food as well as olfactory communication.
Researchers at the Technical University of Munich (TUM) and the Finnish research institute Turku PET Centre and have discovered a new mechanism controlling satiation. According to the recently published study, the hormone secretin induces satiation by activating brown adipose tissue.
How has the corona pandemic affected the dietary and exercise behavior and thus the weight of adults? Researchers at the Technical University of Munich (TUM) have investigated this question and found that about 40 percent of those surveyed have gained weight since the start of the pandemic and that slightly more than half of those surveyed have exercised less than they did before the corona crisis.
The pandemic-related closure of sports fields, gyms, and fitness studios in Germany has led to a significant increase in cycling in the public green spaces of large cities. This is the conclusion reached by researchers at the University of Bayreuth in a new study published in PLOS ONE. The study is based on anonymised data from the Strava fitness app, which is used by more than 73 million people worldwide.
Scientists of the Technical University of Munich at the German Heart Centre Munich and the Faculty of Sport and Health Sciences have been successfully cooperating for many years. On the occasion of the "Day of the Child with Heart Disease" on May 5th, Prof. Renate Oberhoffer-Fritz, Dean of the Faculty of Sport and Health Sciences and holder of the Chair for Preventive Pediatrics, and Prof. Peter Ewert, Deputy Medical Director of the German Heart Center Munich and Director the Clinic for Congenital Heart Defects and Pediatric Cardiology present this fruitful interdisciplinary collaboration in this interview.
Researching the effects of plastic particles on the human body and developing a health policy strategy for assessing the resulting risks is the goal of the new European research network PlasticsFatE. The University of Bayreuth, together with 26 other universities, institutes, and organisations from ten EU member states, is participating in the project. The European Union is funding the four-year project to the tune of € 6 million, with the University of Bayreuth receiving more than € 465,000. The project was launched on 28 April 2021 at a virtual kick-off event for its partners.
Musty, moldy, smoky or horse dung-like smelling cocoa is not suitable for chocolate production. As part of a larger research project, a team of scientists led by Martin Steinhaus from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has identified the odorants responsible for such off-flavors. The food industry can now use these results to objectively assess the sensory quality of fermented cocoa based on odorant concentrations. The research team published the data in the Journal of Agricultural and Food Chemistry.
The plasticisers contained in many everyday objects can impair important brain functions in humans. Biologists from the University of Bayreuth warn of this danger in an article in "Communications Biology". Their study shows that even small amounts of the plasticisers bisphenol A and bisphenol S disrupt the transmission of signals between nerve cells in the brains of fish. The researchers consider it very likely that similar interference can also occur in the brains of adult humans. They therefore call for the rapid development of alternative plasticisers that do not pose a risk to the central nervous system.
Around two thirds of men and half of women in Germany* are overweight, according to statistics collected by the German Obesity Society. Concurrently millions of people want to lose weight. One way to do this is exercising. But what influence does sport have on (direct) eating habits? Scientists at the Technical University of Munich (TUM) and the University of Nebraska (USA) have now investigated this question for the first time.
