  • The Certification of Reference Materials of Dry-Mixed Maize Powder with different Mass Fractions of 1507 Maize, Certified Reference Materials ERM-BF418, Certification Report

Abstract

This report describes the preparation and certification of dry-mixed maize powder Certified Reference Materials (CRMs) with different mass fractions of genetically modified (GM) 1507 maize powder (CRMs ERM-BF418a, ERM-BF418b, ERMBF418c and ERM-BF418d). The CRMs were processed in 2004 and certified in 2005 by the European Commission, Directorate General Joint Research Centre, the Institute for Reference Materials and Measurements (IRMM) in Geel, Belgium.
Seeds of non-modified maize and 1507 maize, both supplied by Pioneer Hi-Bred International (Johnston, IA, USA), were rinsed with demineralised water, drained and dried at 30 °C in order to minimise dust contamination from other crops. After a two step grinding process, transforming the seeds into a non-modified maize powder and a 1507 GM maize powder, the CRMs were gravimetrically prepared and homogenised by turbula- and dry-mixing.
The CRMs are intended for the quality control and calibration of methods for the detection and quantification of genetically modified food and feed. The 1507 mass fractions of ERM-BF418 were verified with the help of a DNA-based detection method. The CRMs are available in glass bottles containing 1 g of maize powder closed under argon atmosphere.
