title: Ochratoxin A and aflatoxins in dried vine fruits from the Iranian market.
abstract: Forty samples of dried vine fruit (raisin, n = 22; currant, n = 18) were collected in 2009-2011 from the Iranian market. Aflatoxins (AFs) and ochratoxin A (OTA) were determined in these samples after immunoaffinity column clean-up by high performance liquid chromatography (HPLC) with fluorescence detection. The limit of quantification (LOQ) for AFs B1. B2, G1, G2, and OTA were 0.62, 0.50, 0.70, 0.40, and 0.42 ng/g, respectively. AFB1 was found in one sample of raisin (0.64 ng/g) and in two samples of currant (0.20 and 0.63 ng/g). AFB2 (0.33 ng/g) and AFG2 (0.49 ng/g) were found in 2 samples of currant. OTA was detected in 3 of the 22 samples of raisin (mean 2.21 ng/g) and in one sample of currant (2.99 ng/g). The results show that in AFs and OTA levels are well below the regulatory limits both of the European Union and of Iran.
