Abstract
Die Paraffinfraktion aus rohen Extrakten von Lebensmitteln und Verpackungsmaterialen wurde mittels LC isoliert und durch simultane Abdampfung direkt in den GC transferiert. Typische Paraffinmuster verschiedener Verpackungsmaterialien (Sisalsäcke, Karton, Plastikfolien, Wachspapier und Paraffin) werden charakterisiert. Starke Verunreinigungen der Lebensmittel wurden bei Sisalsäcken, Kartonschachteln, Wachspapieren und Wachskarton gefunden. Die Verunreinigung von Käse durch eine Schicht Paraffin war vergleichbar gering. Paraffins from raw extracts of foods and packing materials were isolated by LC and directly transferred to GC, applying concurrent eluent evaporation and a loop-type interface. Paraffins from various packing materials have been characterized: sisal bags, cardboard boxes, plastic films, wax-coated paper and cardboard as well as paraffin coatings. Important food contamination was found for sisal bags, cardboard boxes, and waxcoated paper/cardboard. Contamination by paraffin coatings on cheese was surprisingly small.Keywords
