Zusammenfassung

Es wurde der Gehalt von Cadmium und Nickel in Sonnenblumenkernen untersucht. In 55 Proben aus Nord-Amerika und Europa war der Cadmiumgehalt durchschnittlich 0,32-0,54 mg/kg. Der Gehalt in Sonnenblumenkernen aus China und Ägypten - als Vogelfutter vorgesehen - war viel niedriger. Der Gehalt von Cadmium in diesem Lebensmittel kann ein Gesundheitsrisiko sein. Die Behörde in Dänemark empfiehlt daher den Verzehr größerer Mengen von Sonnenblumenkernen über längere Zeit zu vermeiden. Der Gehalt von Nickel in 25 Proben von Sonnenblumenkernen - als Lebensmittel vorgesehen- war 2,5-5,3 mg/kg. Dieser Inhalt ist vergleichbar dem hohen Nickelgehalt verschiedener Nüsse.

Summary

High cadmium and nickel contents in sunflower kernels intended for human consumption are reported.

The cadmium contents of 55 samples from North America and Europe were 0.25-0.69 mg/kg with averages from different countries of 0.32-0.54 mg/kg. The contents in kernels from bird seeds (i.e. animal feed) from China and Egypt were much lower.

The cadmium content of sunflower kernels for human consumption might pose a risk to human health. Danish authorities recommend the Danish consumers do not eat large amounts of sunflower kernels for a long period of time.

The nickel contents of 25 of the samples of kernels for human consumption were 2.3--5.3 mg/kg. This is comparable with that found in different kinds of nuts with high nickel contents.
