title: Development of antioxidant active films containing sodium ascorbate (SA) and ethylene vinyl alcohol (EVOH) to extend the shelf life of peanut.
abstract: In this study, low-density polyethylene (LDPE) containing oxygen scavenger based on sodium ascorbate (SA) and ethylene vinyl alcohol (EVOH) at 5, 10 and 15 % concentrations were produced through extrusion method. In addition, the effect of size of SA, thickness LDPE (7.5, 15, 30 and 45 μm), and number of layers (monolayer, two-layers, three-layers and four-layers) were investigated. Oxygen and water vapor permeability, tensile stress, SA migration and antioxidant activity, thermal stability, scan electron microscopy (SEM), and FT-IR of the films were measured. Moreover, the performance of produced films to prevent of oxidation of packaged peanuts during storage at 40 °C was studied. The results revealed that the active films containing SA (especially at 10 % SA) present suitable performance and features to increase the shelf-life of peanuts.
