Determined a new method to establish the antioxidant capacity of extra virgin olive oil

02.05.2008
A group of scientists from the Nutrition and Food Science Department from the Faculty of Pharmacy of the University of Granada have reported the beneficial effects of extra virgin olive oil on human health, determining in vitro and in vivo the antioxidant power that the examined extra virgin olive oil samples present.

With this work, researchers have found out a more effective method nowadays in order to establish the antioxidant capacity of extra virgin olive oil.

Research has been directed by doctors M. Carmen López Martínez, Herminia López García de La Serrana and José Javier Quesada Granados, and its main author is Cristina Samaniego Sánchez. The scientists have prepared four methods that let us know know the antioxidant capacity and he beneficial effect of the extra virgin olive oil obtained from olives of the Picual variety.

Work "in vitro"
In order to carry out this work, they determined the best method to calculate the in vitro antioxidant capacity in oil samples. They concluded that, among all the applied methods, the ABTS was the most suitable in order to study this kind of samples as it shows the correlation with the total polyphenol index in a better way. Moreover, scientists observed that the reproducibility of the results of these methods is good and that the variation coefficients obtained by the different methods are acceptable, which makes it possible to conclude, generally, that the four studied methods could be applied to measure the antioxidant oil capacity.

Scientists from Granada are not discarding the idea of registering some patents related to this research soon, since they already have experience in getting patents related to other studies on food, such as alcoholic drinks. Their research is applicable to every kind of olive oil, and these methods could be used in the areas where olive groves are cultivated, regardless of the variety of olive used in the oil obtaining process.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
