Untargeted screening and in silico toxicity assessment of semi- and non-volatile compounds migrating from polysaccharide-based food contact materials

•Migrating compounds of polysaccharide-films were identified by UHPLC-TIMS-TOF-MS.•Monoacetylated maltose migrated from acetylated starch at 70 °C/2 h with lipophilic simulant.•Dibutyl phthalate (DBP) migrated from all biopolymers at high temperature/short time.•No in silico toxicity alert was identified for the migrating compounds.•Organocatalytic acetylated FCM biopolymers did not show any safety concern.
