Consumption of chia, flax and seame seeds has increased because of their nutritional and functional properties. An untargeted metabolomics approach was used in this study with H/D NMR, compared to previous mass spectrometry based targeted approaches. Three groups of metabolites - polyphenol based caffeoyl derivatives and lignans, and cyanogenic glycosides were identified in the 3 seeds, and seven authenticity markers (polyphenol based and cyanogenic glycosides) were able to distinguish between the 3 types of raw seeds. The authenticity markers in sesame seeds were validated by combining different concentrations in cookies and baking them. Two of the markers were unchanged by the baking process and regarded as good indicators of sesame seed authenticity in baked products.
