[Determination of trace elements in dietary fats and emulsifiers by flameless atomic absorption spectrophotometry. 1. Determination of the ionogenically bound heavy metals copper, iron, nickel, zinc, lead and cadmium in dietary fats].
The knowledge of the trace metal contents in dietary fats is of considerable interest from the viewpoints of food hygiene and and storage stability. In the framework of the present paper, it is dealt with the determination of the ionogenically bound heavy metals copper, iron, nickel, zinc, lead and cadmium by means of flameless atomic absorption spectrometry (AAS). Problems related to trace analysis in dietary fats are discussed. Problem-oriented surveys in the form of tables inform about:--analytical conditions of the AAS technique,--metal contents as compared to data with the approved standard method,--contents of the ionogenically bound toxic trace elements cadmium, zinc and lead in samples of various dietary fats currently used in the German Democratic Republic.
