Until that point, the methods available to detect the presence of mandarin in orange juice were based on chemical markers. These markers were unreliable and highly dependent on environmental conditions.
AZTI designed an innovative DNA analysis methodology using a panel of two fluorescent TaqMan probes in a Real-Time PCR system, enabling the detection of orange juice adulteration with mandarin. This represented a global milestone and has been patented.
Genetic identification of mandarin enables rigorous controls to combat fraud and improve traceability in the juice and nectar sector.
The methodology has been validated by the external certification body SGF.
