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.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
