Abstract :

GM content in food and feed is strictly regulated in most countries around the world. The implementation of regulation requires the establishment of GMO detection methods that are specific, reliable, sensitive and suitable for quantitative GMO detection. Meat adulteration and mislabeling is also a world widely concern in recent years. However, the determination of adulteration ratio has become a critic issue due to the lack of effective quantitative technique. This presentation will report droplet digital PCR method for quantitative determination of GMO rice events and meat species in food. The experimental amplification results of relative quantification all perfectly matched the theoretical results and the limit of quantitative (LOQ) of GMO was determined to be 0.1%, lower than the labeling threshold level of the EU and many countries, while the meat species method was confirmed to be 1% (w/w). Moreover, its use for several types of food, feed and seed matrices commonly found in routine samples has been verified.
