General description

Certan Vial
Ochratoxin is a mycotoxin, produced by genus Aspergillus and Penicillium. Ochratoxin producers are widely distributed in foods such as cereals. Ochratoxins are isocoumarin derivatives. Ochratoxin B is dechlorinated analog of ochratoxin B.

Application

Ochratoxin B was used as standard to investigate the degradation of ochratoxin A and B by white rot fungus during solid state fermentation of barley contaminated with ochratoxins. It may be used in displacement immunoassay for detection of ochratoxin A.
