Abstract: The presence of genetically modified organisms (GMOs) in food and feed products is subject to regulation in the EU and elsewhere. As part of the EU authorisation procedure for GMOs intended for food and feed use, reference materials must be produced for the quality control of measurements to quantify the GMOs. Certified reference materials (CRMs) are available for a range of herbicide- and insect-resistant genetically modified crops such as corn, soybean and cotton. Here the development of the first CRM for a GMO that differs from its non-GMO counterpart in a major compositional constituent, i.e. starch, is described. It is shown that the modification of the starch composition of potato (Solanum tuberosum L.) tubers, together with other characteristics of the delivered materials, have important consequences for the certification strategy. Moreover, the processing and characterisation of the EH92-527-1 potato material required both new and modified procedures, different from those used now routinely for genetically modified seed CRMs.
