New analysis services for the wine-producing sector

20.07.2005


The AZTI-Tecnalia laboratories have launched new methodologies for analysing parameters that, up to now, have not usually been analysed for wines - ocratoxine A and histamine. The design of these new analysis methodologies arose from the need for adaptation to new market demands in the wine-producing world.

To make an analytical determination of Ocratoxine A, AZTI has launched a HPLC technique based on fluorescence detection for wines. Ocratoxine A (a mycotoxin produced by various fungi such as Aspergillus and Penicillin). Although in wines their presence is very low, the exigencies in exports to the western markets is having effect.

As regards determining histamine, the technique used is also HPLC. The presence of histamine in wines (due to the decarboxylation of the histidine amino acid by heterofermentative Lactobacillus), while not being a major health problem, has an effect on the quality of the wine, and so its control is necessary in a number of trading transactions.



Apart from these new analytical applications and due to the needs of the quality systems established in the various companies, AZTI has been analysing - over the past 8 years – chlorophenols and chloroanisols in various points of the wine production process, including the corking process and barrels. These components, the degradation of which give rise to compounds which are attributed with the taste or the smell of being "corked" or “musty”, is one of the most common defects in wine and most quickly detected by the consumer and, in many cases, the main cause of returns that are suffered by the wine companies.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
