Decomposition of ochratoxin A by heat and gamma-irradiation.
Up to 50% of initial amounts of 2 and 100 ng/ml ochratoxin A were decomposed after gamma-irradiation of solutions in water, in 2% aqueous NaCl or an aqueous solution of 2% NaCl and NaNO2. Ochratoxin A in these solutions was not decomposed, however, after heating at 20, 121 or 135 degrees C for 15 min.
