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.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
