Is your favourite red wine really that good for you?

19.04.2007
Red wine is being widely touted for its health benefits, but not all red wines may act the same according to researchers at the University of Hertfordshire.

Dr Richard Hoffman and his Erasmus student, Conny Johansson are using the University’s new chemistry laboratories to test a random selection of red wines to determine their levels of resveratrol.

Resveratrol is a natural antioxidant found in red wine and red grape skins, known to protect against a range of illnesses and diseases including neurodegenerative diseases such as Parkinson's or other dementias, cancer and heart disease and more recently documented for its role in extending lifespan.

It is also found in peanuts and Dr Hoffman and his team are also currently examing their anti-cancer properties.

According to Dr Hoffman, although the health benefits of resveratrol found in red wine have been well documented, no one has systematically measured its levels in particular wines before.

“As a result, they assume that all red wines are the same, but this is certainly not the case as the levels of resveratrol vary.”

Dr Hoffman and Mr Johansson are using new state-of-the-art High Performance Liquid Chromatography (HPLC) and Liquid Chromatography Mass Spectrometery (LCMS) to separate and collect the compounds found in the wines.

They plan to be able recommend the healthiest bottle of wine among those they have tested. They also aim to work with wine suppliers and retailers so that they can persuade them to put health indicators on their products.

“The long-term aim is for people to be able to go along to the supermarket and to be able to know at a glance the levels of resveratrol contained in the wines they are choosing,” said Dr Hoffman.

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...
