dc.description.abstractThe stability of deoxynivalenol (DON), deoxynivalenol-3-glucoside (DON-3-glucoside) and ochratoxin A (OTA) during spaghetti production and cooking was investigated. Initial mycotoxin concentration, boiling time and use of egg as ingredient were assayed as factors. DON was stable during kneading and drying, but a consistent reduction of DON (> 40 %) was observed in boiled spaghettis. According to our results, DON was transferred to broth, where it was not degraded, and boiling time determined the extend of the transfer. A DON leaching model was fitted to data with a high goodness fit (r2 = 0.99). This model can be used for prediction of final DON concentration in cooked pasta, and a useful tool in risk assessment models. DON-3-glucoside is totally stable through the pasta making process; moreover DON-3-glucoside is slightly released from pasta components and it is leached to broth. Similarly, OTA is also stable during pasta making, however, it is scarcely transferred to broth during boiling. The presence of egg as ingredient did not affect the final mycotoxin concentration in pasta in any case.
