Zusammenfassung
Zur Wiederfindung von Holzrauch-Phenolen aus Fett-Fisch wurde eine ExtrahierMethode mit Lösungsmitteln angewandt. Es konnte bewiesen werden, daß die Wiederfindungsrate bei einigen dieser Phenole niedrig ist, wenn das Fett durch Ether-Extraktion unter stark alkalischen Bedingungen entfernt wird. Es wurde eine verbesserte Methode entwickelt, die these Schwierigkeit überwindet, so daß sie zur Bestimmung von Phenolen in kaltgeräucher-tem Weiß- und Fett-Fisch angewandt werden konnte.
Summary
A solvent extraction technique has been used to determine the recovery of a range of wood smoke phenols from fatty fish. It has been shown that the recovery of a number of these phenols is poor when fat is removed by ethyl ether extraction under strongly alkaline conditions. A revised technique has been developed that overcomes this problem and the method has been used in the determination of phenols in cold smoked white and fatty fish.
