Radioimmunoassay of ochratoxin A in barley [PDF]
A simple and rapid radioimmunoassay was developed for the quantitative determination of ochratoxin A in barley. [14C]ochratoxin A, with a specific activity of 130 Ci/mol, was used as the tracer. Toxin levels below 100 ng/ml required a cleanup step. Three methods (the Association of Official Analytical Chemists cleanup method, the solvent partition ...

Fate of ochratoxin A in brewing [PDF]
The fate of ochratoxin A in brewing was investigated by adding (3H)ochratoxin A to the raw materials at 1- and 10-mug/g levels during mashing in a conventional microbrewing process. The results indicated that large portions (28 to 39%) of the added toxin were recovered in spent grains, with less recovery in the yeast (8 to 20%) and beer (14 to 18 ...
