title: Synthesis of biodegradable films with antioxidant properties based on cassava starch containing bixin nanocapsules.
abstract: Biodegradable and active packaging based on cassava starch incorporated bixin nanocapsules with different concentrations were developed. The physical, mechanical, barrier properties and antioxidant activity of the active packaging were studieds. The films incorporated with bixin nanocapsules were found to be homogeneous and thermally stable. Films with higher concentrations of bixin nanocapsules exhibited a significant decrease in tensile strength, water solubility and increase in elongation at break and water vapour permeability, well as, significant improvement in protection against UV and visible light. The films were used to pack sunflower oil under accelerated oxidation conditions (65 % RH/35 °C). Sunflower oil packaged in films with bixin exhibited lower oxidation rates, thus maintaining its freshness according toCodex Alimentariusguidelines (<10 mEq kg-1). Films containing bixin nanocapsules are very promising materials for use as packaging with antioxidant properties for maintaining food safety and extending the shelf life.
