Mycotoxins in cereal grain. Part II. The fate of ochratoxin A after processing of wheat and barley grain.
Ochratoxin A was to be evenly distributed in kernels of different lots of wheat and barley grain. Dry cleaning and wet cleaning did not eliminate ochratoxin from grain. After milling the level of ochratoxin in flour was similar to its concentration in bran. In pearl barley concentration of ochratoxin A stated only 10-30% of initial concentration in barley grain. Detoxification is necessary for the whole kernel, because processing did not remove ochratoxin A effectively.
