The development of analytical methods, suitable for the detection and quantification of GMO contents in agricultural commodities and processed products is essential to support the control of compliance with regulatory provisions concerning the use of GMO and GMO-derived material for the production of food and feed. DNA-based assays for the detection of GMO within the food and feed chain must cope with a number of challenges that are linked either to the background of the genetic modification and the genetic composition of the GMO, or to adverse effects of technological parameters and manufacturing practices on the availability of target sequences. Among the latter, limitations are mainly given by the complexity of food composition and by the degradation/elimination of analytes during manufacturing processes. In the presented studies the effects of food processing on the quantification of GMO contents were investigated. In addition to the assessment of established PCR-based technologies for the quantification of DNA sequences, an alternative ligation-dependent modular system for the qualitative and quantitative detection of GMO in composed and processed food products was developed.
