| Abstract: | Summary A previously published 1] liquid chromatographic method for the determination of ochratoxin A in corn, barley and kidney has been modified for application to parboiled rice with quantification by high performance thin layer chromatography (HPTLC). The method has been validated by spiking uncontaminated extracts of rice with ochratoxin A over the range 0 to 198  g kg–1. The proposed method has some significant advantages over the current AOAC method 2], especially for determining low levels of ochratoxin A in parboiled rice. |
