An accurate and rapid method, was devised for the Dryer Humidity sensor identification and quantitation of dimethyl yellow dye in curry, based on liquid chromatography-tandem mass spectrometry interfaced with electrospray.Mass spectral acquisition was done in positive ion mode applying two fragmentation transitions to provide a high degree of selectivity.The extraction system provided a very high recovery (100.

0% to 105.8%) and good results were obtained for the limit of detection (5 μg/kg) and limit of quantitation (16 μg/kg).The applicability of the method to identifing and Epilobium quantifing the unauthorised dimethyl yellow dye in curry was demonstrated.
