Identification of NIAS in PP films used as food packaging

Migration of non volatile compounds from twenty six PP films used as food contact materials has been studied in four simulants (ethanol 95% and 10%, acetic acid 3% and Tenax ®) and analyzed by UPLC-MS/QTOF. Seventy six compounds have been identified, where 76% of them were non-intentionally added substances (NIAS) coming from degradation of additives used, impurities or compounds of unknown origin.
Six films didn’t comply with the European Regulation Nº 10/2011/EU. Other films surpassed the maximum concentration recommended by Cramer for the compounds of class II or III when ethanol 95% was used as simulant. An article about this research was published in Talanta.
