The present work describes a fast and straightforward DNA test that identifies green pea adulteration in pistachio nuts without requiring a statistical data interpretation process. The plastid trnL (UAA)-trnF (GAA) intergenic spacer length widely varies among plant taxa, so the PCR-CE protocol that operates on the intergenic spacer holds the potential to reveal adulteration with a plethora of adulterants. The PCR-CE assay described in the present work can be adopted readily by food-quality laboratories in the public sector or the food industry as an easy and reliable method to analyze pistachio authenticity. © 2020 Society of Chemical Industry.
