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 %.

食品中赭曲霉毒素A的纳米流体提取

摘要 赭曲霉毒素 A (OTA) 是一种真菌的有毒和致癌代谢物,其监测需要准确和精确的分析方法。通过纳米流体萃取结合 HPLC-FLD 对葡萄干样品中痕量 OTA 的定量测定进行了评估。对影响OTA提取效率的实验参数进行了研究和优化。经验证的方法具有较低的检测和定量限(0.2 和 0.5 ng g-1)。此外,在最佳条件下,以日内和日间精密度 (RSD %) 的相对标准偏差表示的方法重复性低于 15% (n = 3)。该方法也已成功应用于实际样品中痕量 OTA 的分析,其相对回收率在 70.3-84.7% 范围内令人满意。
