A review on pomegranate peel extract incorporated chitosan based polymer for biodegradable food packaging / Nur Sabrina Nazeri

The current research presents an in-depth analysis of the effects of adding pomegranate peel extract as a functional component to a variety of edible packaging materials. This review provides an overview of the recent developments and achievements in active edible packaging materials enhanced with pomegranate peel and their useful applications. Recently, improvements have been made to prolong the shelf life of food stuffs and controlled release and transport of nutraceuticals and bioactive compounds by utilizing pomegranate fruit and its underutilized elements. Adding pomegranate peel extract to an edible matrix can increase structural, mechanical, and biochemical properties like antioxidant and phenolic content and antibacterial activity, as well as the peel's compatibility with the matrix. Incorporating pomegranate peel extract into an edible matrix and applying it to food products could also aid in the retardation of natural colors, lipid oxidation, microbiological contamination, and influence the shelf life of food products by preserving their organoleptic properties. On the other hand, additional research is required to investigate the practical consequences that are associated to the influence of pomegranate peel extract on the optical, physical, and barrier properties of edible films and coatings.
