DNA-based methods are preferred for testing of raw or partially processed food products.  More heavily processed food can be more of an analytical challenge; DNA methods are still applicable provided the quality of DNA enables amplification despite being hampered by the processing procedures or presence of inhibitors or due to complexity in composition in terms of ingredients.

This review (purchase required) focused on possible approaches for adhering to the regulatory requirements while verifying UGM in processed food products. Technical challenges and approaches for extracting purified DNA and necessary quality checks are described. The article covers amplification as well as sequencing-based methods which can be applied to check for presence of UGM ingredients amongst a complex mix of other ingredients. The authors discuss the comparative assessment of these methods in the context of regulatory testing requirements and availability of information of transgenic DNA.

12358146260?profile=RESIZE_584xIn March 2023, Dr Malcolm Burns, Head of the GMO Analytical Unit at the National Measurement Laboratory at LGC presented presented at the International Conference on GMO and New Genomic Techniques on 'Analytical strategies for detection of GMO's and NGT products- status and challenges'. The presentation explored some of the opportunities and challenges for the development of methods for the detection of NGT products.
