Polylactide films produced with bixin and ATBC: effect of thermal treatment on bixin stability and migration kinetic

Résumé

The incorporation of antioxidants into a polymeric structure to produce antioxidant active materials is an alternative way to extend the shelf-life of fatty food products. Even tough polylactide (PLA) present satisfactory mechanical properties, it requires improvements to be used as an antioxidant material for food packaging. Bixin, a carotenoid with hydrophobic character, presents coloring and antioxidant properties and hence is a potential antioxidant additive for PLA. Considering bixin thermal low stability, films produced with bixin and the plasticizer acetyl tributyl citrate (ATBC) were produced by different thermal processes. The effect of thermal treatments over films color changes and bixin stability was evaluated, also as its effect on bixin’s kinetic of migration.
