The purpose of this study was to investigate the effect of pomegranate peel powder on the physicochemical, barrier, and pH sensitivity of the films based on cassava starch. The pomegranate peel powder (PPP) was used at levels of 2, 4, 6, and 8% w/v in starch film formulation, and the thickness, water solubility, water vapor (WVP) and oxygen permeability, and opacity were determined, and the color variations of the films were also measured after immersion in different pH buffers (pH 4.0-9.0). The results demonstrated the addition of PPP to film formulation and increasing its levels, the water solubility, opacity, WVP, and oxygen permeability were increased (p |
