Accelerated solvent extraction (ASE) is an alternative sample extraction procedure for fumonisins in corn and corn products. ASE gave results comparable to that of a draft CEN method, but required less extraction time. Furthermore, ASE gave significantly higher quantitative values than another method reported for extraction of fumonisins (Trucksess et al., 1995).

Tests with various clean-up materials after optimisation of different parameters showed that the use of Oasis® material resulted in matrixless chromatograms in HPLC-FLD. The selectivity and detection limit of the method was improved by using LC-MS/MS as the detection system. Mean recovery was 100%, and no negative food matrix effects could be observed.

Accelerated solvent extraction (ASE) is an alternative sample extraction procedure for ochratoxin A in roasted coffee. ASE results are comparable to that of the modified Koch method, but required less sample preparation time. Furthermore, ASE gave higher quantitative values than other methods reported for extraction of ochratoxin A. In the end less harmful water could be used for extraction.ZUSAMMENFASSUNG: Die beschleunigte Lösungsmittelextraktion (ASE) ist ein alternatives Verfahren für die Bestimmung von Ochratoxin A in Röstkaffee zu bisherigen Methoden. Die ASE ergab im Vergleich zu der modifizierten Koch-Methode vergleichbare Ergebnisse, bei verkürzter Probenaufbereitungszeit. Im Vergleich zu der Koch-Methode wurden mittels ASE höhere Ausbeuten des Ochratoxin A erzielt. Letztlich konnte als Extraktionsmittel das toxologisch unbedenklichere Wasser eingesetzt werden.
