Jan Oszmianski, leading a team at the Agricultural University of Wroclaw, Poland, compared clear and cloudy varieties of apple juice, and found that cloudy juice contains four times the concentration of polyphenols. Polyophenols are also found in dark chocolate, red wine and are widely reported to have anti-cancer activity. The research published this month in the SCI’s Journal of the Science of Food and Agriculture (DOI: 10.1002/jsfa.2707).
Lucy Ede, Head of Products at the juice company Innocent, said they already use cloudy apple juice in their products. “Cloudy juices taste better and have amazing body, which is important for us,” she said. “But the fact that cloudy juices have more health benefits is extra exciting and definitely encourages us to use them.”
Clear juice far outsells cloudy juice because of the perception by consumers that is purer. But it is the process of clarification that removes the beneficial compounds locked away in the apple pulp. Retailers also tend to favour clear juice because it has a longer shelf life than cloudy juice.

Extra Special Espresso
The exact conditions required to make the perfect espresso are revealed this week in Chemistry & Industry. Researchers, from the University of Navarro used both electronic ‘noses’ and human tasters to determine the exact ratio of coffee to water required to avoid the unpleasant tastes of burnt rubber, motor-oil, sulphur and ash associated with over-brewed coffee. The amount required depends on the coffee used – blends containing the cheaper Robusta variety required more coffee than pure Arabica beans.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
