| Abstract: | Monitoring of Ochratoxin A (OTA), a toxic and carcinogenic metabolite of fungi, requires accurate and precise analytical methods. Quantitative determination of OTA at trace level in raisin samples was evaluated by nanofluid extraction coupled with HPLC–FLD. The experimental parameters affecting the extraction efficiency of OTA were investigated and optimized. The validated method has low detection and quantification limit (0.2 and 0.5 ng g−1). Moreover, under optimum conditions, the repeatability of the method expressed as the relative standard deviation for intra-day and inter-day precision (RSD %) was below 15 % (n = 3). This method has also been successfully applied to the analysis of trace amounts of OTA in real samples with satisfactory relative recoveries in the range of 70.3–84.7 %. |
