"The use of the denotation 'pure Styrian pumpkin seed oil' requires that this is 100 per cent pure and results from a first pressing procedure in local mills," say the researchers, from Austria's Montanuniversitaet Leoben.

They used a fingerprinting technique called inductively coupled plasma mass spectrometry (ICP-MS) to analyse the rare earth element (REE) composition of pumpkin seeds and oils from Styria as well as other geographic regions such as China and Russia.

Using the technique, the scientists were able to show that pumpkin seeds and oils from different regions showed variations in REE fingerprints that were independent of ripeness and seasonal changes in weather conditions and were suitable for routine analytical testing.
