Sažetak
The aim of this study was to test gamma irradiation in reduction of aflatoxin B1 (AFB1) and ochratoxin A (OTA) toxicity. For this purpose, maize seeds samples contaminated with AFB1 (n=30) and dry-cured meat products contaminated with OTA (n=24) were investigated. Additionally, non-irradiated and gamma irradiated AFB1 and OTA standard solutions were tested for cytotoxicity and analyzed on LC-MS/MS. Gamma irradiation (5 and 10 kGy dose) reduced AFB1 level in maize seed samples for 35.1 to 98.6 %. In dry-cured meat samples gamma irradiation (up to 10 kGy dose) reduced OTA level for 17.70 to 33.66 %. Gamma irradiated AFB1 and OTA were less toxic to cells than non-irradiated mycotoxins, and resulted with reduced AFB1 and OTA level. In conclusion, gamma irradiation reduced AFB1 and OTA level in different commodities and their radiolytic products were less toxic, implying that gamma irradiation can be safely used for decontamination of mycotoxins in various feed and food.
