Zusammenfassung

Die Erzeugung von freien Radikalen als Resultat des oxidativen Abbaues von Lipidmolekülen während des Erhitzens von Traubenkernöl wurde durch die Kombination von „spin trapping“ und elektronenparamagnetischer-Resonanz-(EPR)-Spektroskopie gezeigt. Die Auswirkungen der Temperatur auf die Geschwindigkeit des Entstehens und des Abbaus des Addukts mit der “spin trap”N-t-butyl-α-phenylnitron (PBN) wurde im Bereich von 105–180°C untersucht. Die Ergebnisse zeigen, daß für das Studium von Prozessen mit freien Radikalen in Ölen in situ im Hohlraum des Spektrometers bei Temperaturen bis zu 180°C PBN geeignet ist.

Abstract

The generation of free radical intermediates as a result of the oxidative degradation of lipid molecules during the heating of grape seed oil has been established by a combination of “spin trapping” and electron paramagnetic resonance spectroscopy. The effects of temperature on the rates of formation and decomposition of the adduct with the spin trapN-t-butyl-α-phenylnitrone (PBN) have been investigated over the temperature range 105–180°C. The results show that PBN can be used for studies of free radical processes in oils in situ in the spectrometer cavity at temperatures up to 180°C.
