Zusammenfassung

Der Gehalt an Cadmium, Nickel, Mangan, Blei, Zink, Eisen, Zinn, Kupfer und Arsen wurde in frischer Schafsmilch und in Salzlakenkäse, jeweils gelagert in Gläsern oder Zinnbehältern, mit den entsprechenden Laken durch Atomabsorptionsspektroskopie bestimmt. Die Ergebnisse wurden mit den früheren verglichen. Obleich die Werte mit denen anderer Autoren vergleichbar waren, zeigten unsere Werte, daß von den Zinnbehältern und aus der natürlichen Salzlake Metalle übergehen; insgesamt ergab sich, daß in Glasbehältern niedrigere Metallwerte waren. Wir empfehlen daher für die Käse gereinigte Salzlake als auch Gläser für die Konservierung zu verwenden, um die Kontamination mit den obigen Metallen durch die Zinnbehälter und durch die Salzlake zu verringern.

Summary

The levels of cadmium, nickel, manganese, lead, zinc, iron, tin, copper and arsenic in fresh sheep's milk, white brined cheese preserved in glass jars and in tin containers and their corresponding brines, salt and tin plates were determined by atomic absorption spectrophotometry. The results have been compared with those reported in recent years. Although metal levels were comparable with other investigators' data, our data shows that white brined cheese picked-up metals from tin containers and from the naturally contaminated salt, on the contrary brined cheese in preserved glass jars showed lower levels of metals. We recommend a purified salt for brine preparation and glass jars for white cheese preservation in order to minimize cheese contamination with metals from tin cans and salt.
