Description
Summary:The aim of this study was to develop and characterize antioxidant-active films for potential food packaging applications. The films were produced by casting aqueous solutions containing semolina flour (6% <i>w</i>/<i>w</i>), pectin extracted from passion fruit (1% <i>w</i>/<i>w</i>), inverted sugar (1% <i>w</i>/<i>w</i>), and sucrose (1% <i>w</i>/<i>w</i>), incorporating hydroalcoholic extracts from jatoba stem bark (X<sub>1</sub>) and pods (X<sub>2</sub>) at concentrations ranging from 0 to 1% (<i>w</i>/<i>w</i>). The films were characterized in terms of their functional, physical, chemical, structural, and degradation properties. The formulation that showed the best performance, referred to as the optimized formulation (FO), contained 0.5% X<sub>1</sub> and 0.5% X<sub>2</sub>, presenting a high phenolic compound content (8.80 mg GAE/g), strong antioxidant activity as determined by the DPPH method (75.28%) and FRAP assay (6.02 mmol FeSO<sub>4</sub>/g), good thermal stability (350 °C), and a high soil degradation rate (83.47% in 15 days). These results indicate that the FO film has potential application as a primary packaging material with antioxidant function for oxidation-sensitive foods, meeting the demand for biodegradable and environmentally sustainable solutions in the food industry.
