文摘

The presence of genetically modified organisms (GMOs) in food and feed products is subject toregulation in the European Union (EU) and elsewhere. As part of the EU authorization procedure forGMOs intended for food and feed use, reference materials must be produced for the quality controlof measurements to quantify the GMOs. Certified reference materials (CRMs) are available for arange 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 amajor compositional constituent, that is, starch, is described. It is shown that the modification of thestarch composition of potato (Solanum tuberosum L.) tubers, together with other characteristics ofthe delivered materials, have important consequences for the certification strategy. Moreover, theprocessing and characterization of the EH92-527-1 potato material required both new and modifiedprocedures, different from those used routinely for CRMs produced from genetically modified seeds.
