Suite à l’obligation d’étiquetage, au seuil de 1 %, des aliments contenant des OGM autorisés, il est nécessaire de disposer de méthodes fiables de quantification. Pour répondre à cette obligation, la technique de PCR quantitative en temps réel semble actuellement la mieux adaptée. Son principe, ses avantages et sa mise en oeuvre pour la détermination de la teneur en OGM de farines de soja sont présentés. Les PCR simplex et duplex sont comparées.
Abstract
Because of the GMO food labelling requirement at the threshold of 1%, the availability of reliable quantitative analytical methods is necessary. The real-time quantitative PCR seems to be the most accurate method for GMO quantification. Its principle, advantages and application to the determination of GMO content of soybean flour samples are presented. Simplex and duplex PCRs are compared.
