Abstract In 2009 RIKILT conducted a study on about 2,000 eggs to evaluate three different analytical verification methods: carotenoid profiling, fatty acid profiling and isotope ratio mass spectrometry. The eggs were collected from about 50 Dutch farms. The selection was based on the farms’ location and size, and production methods: organic, free range and barn raised. Carotenoid profiling showed a 100% correct prediction of the identity (organic vs. conventional) for the organic eggs in this ‘training set’.
