DOIAbstract
The purpose of this study was to prepare a defatted peanut flour-based film (DPFF); to characterize their physicochemical, optical, barrier, and mechanical properties; and to evaluate the defatted peanut flour package efficacy to preserve the chemical quality of sunflower oil during storage. The film presented high lightness values (L = 86.83). The water vapor permeability was 5.44 x 10-11 g m-1 s-1 Pa-1. Tensile strength and percentage of elongation were 1.01 MPa and 84.01%, respectively. Sunflower oil samples packaged in defatted peanut flour packages (DPFP) was stored during 67 days at room temperature. Peroxide value and conjugated dienes increased less for sunflower oil conditioned in DPFP and high barrier plastic pouches (EVOH) during...
