摘要

The effect of pasta cooking on the enniatins (ENs) contents was evaluated in white and whole-grain pasta. The cooking of pasta was performed for 10 min in boiling water. ENs were extracted from raw and cooked pasta by Solid-Liquid extraction with acetonitrile, and from cooking water by Dispersive Liquid-Liquid Micro-Extraction (DLLME) with a mixture of acetonitrile and carbone tetrachloride. Mycotoxin analysis was performed by Liquid Chromatography coupled to Tandem Mass Spectrometry. The effect of pasta cooking has a marked influence on the reduction of ENs levels. Reductions of 98-100% for ENA, 94-95% for ENA(1), 14-49% for ENB1 and 53-65% for ENBi were achieved after the process. ENs were detected at low concentration levels in water samples. Moreover, it was developed a mitigation strategy to reduce the ENs contents by the combining effect of the thermal treatment and the pH during cooking pasta. The modification of the pH in the cooking water to pH 4 resulted in percentages of reduction close to 100%, while the modification to pH 9 provided percentages from 44 to 100%. Two degradation products were tentatively elucidated after the thermal treatment by Liquid Chromatography-Quadrupole-Linear Ion Trap-Mass Spectrometry.
