Ochratoxin A in several grains in Iran

Abstract

Ochratoxin A content in 100 grain and derived products were determined by high-performance liquid chromatography with immunoaffinity column clean-up and fluorometric detection. Ochratoxin A was detected in 32% of green gram, 13.3% of chickpea, 10% of lentil and 17.5% of wheat flour. Ochratoxin contamination was below the regulatory limits of the European Union and of Iran. Recovery was 97% and the limit of detection was 0.12 ng g⁻¹.
