New EAP-Determination, including Beverage Antioxidative IndeX (BAX)

22.04.2013
</a><strong>Background</strong><br>

For the prognosis of the flavor stability of beer the electron spin resonance (ESR) spectroscopy has been used for the determination of the lag time. The spin-trap reagent (PBN) used to assess the lag time has a significant impact on the results due to an increasing pH-value during the analysis, resulting in a falsification of the rations in a beer sample. <br><br> <strong>Technology</strong><br> We offer a novel method for the assessment of the endogenous antioxidative potential (EAP) of beer and other beverages using a different spin-trap reagent (POBN) in lower concentrations, which results in a beer matrix dependent, linear correlation between the SO2-content and the EAP-value. This correlation offers a new beneficial index number for the evaluation of the beer specific flavor stability (BAX: Beverage Antioxidative IndeX). The BAX provides additional information about the anti- and pro-oxidative properties of the beer matrix independent on the SO2-content. The BAX is affected by the content of metallic ions, hop-acids, sugar, proteins, intermediate Maillard reaction products, etc. and gives information about the consumption rate of the existing antioxidative potential during storage.<br><br>

Besides the higher significance of the EAP-values, the breweries that in fu-ture are going to employ EAP-determination and Beverage Antioxidative IndeX (BAX) as a matter of routine, will be able to detect deviations in the brewing process in time and to intervene selectively, but they will also be able to considerably lower the costs in the area of quality assurance.<br><br> <b>Benefits:</b><ul> <li>Significantly improved procedure for the evaluation of the oxidative stability of beverages (beer, juice, wine, etc.)</li> <li>Reliable EAP-determination</li></ul> <p><strong>IP Rights</strong><br> Patent granted in US and applied for EP (priority date 09/2005) <br><br> <strong>Patent Owner</strong><br> Technische Universität Berlin

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
