Ferment and cook beans for wind-free nutrition

26.04.2006
Research News from the Journal of the Science of Food and Agriculture

Fermenting beans and then cooking them not only reduces the majority of the soluble fibre that leads to flatulence, but also enhances their nutritional quality. Now we know which bacteria are important for the fermentation, reveal findings published online today in the SCI’s Journal of the Science of Food and Agriculture.

Beans are already an important source of nutrients, and many people would eat more of them if it wasn’t for the flatulence. In many situations treating food to remove one problem often reduces its nutritional value, but a team of researchers at Simón Bolívar University in Caracas, Venezuela, have shown how flatulence can be reduced, while the nutritional value is enhanced.

Flatulence is caused by bacteria that live in the large intestine breaking down parts of the food that have not been digested higher in the gut, and releasing gas. Led by Marisela Granito, the researchers had previous shown that fermenting the beans could destroy many of these compounds. Now this team of researchers at has identified the bacteria that perform this fermentation.

Publishing their work in the Journal of the Science of Food and Agriculture, they show firstly that Lactobacillus casei and Lactobacillus plantarum are the key bacteria. These can be encouraged to grow either by deliberately adding it to a batch, or by inoculating with liquor from a previous batch.

Secondly, they discovered that once these fermented beans are cooked, the amounts of nutrients in the bean that could be digested and absorbed had increased significantly.

“Our results show that L. casei could be used as a functional starter culture in the food industry,” says Granito.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
