Abstract
Ochratoxin A is a typical cereal contaminant with strong nephrotoxic activity. Gamma irradiation was used as a technique of food preservation to disinfect the cereal – based baby food of Aspergillus ochraceus, as well as inactivation of ochratoxin A. Unirradiated samples of cereal-based baby food were spiked with A.ochraceus and incubated for 30 days, the fungus could grown reaching to mean counts of 2.3 Í 107 (CFU/g) and produced ochratoxin A in mean amounts of 86 (ppb) through the incubation period. At a radiation dose of 5 (K Gy), the growth of A.ochraceus and the subsequent ochratoxin A production in cereal – babsed baby food were completely inhibited. The results of detoxification trial revealed that destruction of ochratoxin A by gamma irradiation doses had already begun at 5 (KGy). A radiation dose of 10 (KGy), controlled the occurrence of ochratoxin A in cereal – based baby food only by 23%.
