Food fraud is perpetrated with increasing frequency along the food chain, triggering the need for new and modern tools to detect food authenticity. Chia, flax and sesame seeds are well known for the good nutritional characteristics of their oils, but there is a lack of knowledge regarding the authenticity of these seeds and food products containing them as well. In the present work, we propose a method based on targeted metabolomics to identify the polyphenols present in seeds, which can be used as markers of authenticity. We tentatively identified 44 polyphenols in the different seeds by HPLC-DAD-ESI-qTOF (MS/MS). Chemometrics allowed the selection of 12 compounds, which are nominated as novel markers for seed authentication. Some of these compounds were also found in a lab-scale preparation of cookies supplemented with the studied seeds. The proposed chemical markers resisted the baking process, representing good candidates to be used in the authentication of raw material and bakery products containing these seeds.
食品欺诈在食物链上愈演愈烈，因此需要新的现代化工具来检测食品的真实性。奇亚籽、亚麻籽和芝麻以其油类的良好营养特性而闻名，但人们对这些种子及其所含食品的真实性知之甚少。在本研究中，我们提出了一种基于靶向代谢组学的方法来鉴定种子中的多酚，这些多酚可作为真实性的标志物。我们通过 HPLC-DAD-ESI-qTOF（MS/MS）初步鉴定了不同种子中的 44 种多酚。化学计量学允许选择 12 种化合物，它们被提名作为种子鉴定的新型标志物。这些化合物中的一些也存在于用研究种子补充的实验室规模制备的饼干中。所提出的化学标志物能抵抗烘焙过程，是用于鉴定含有这些种子的原料和烘焙产品的良好候选物。
