Abstract
The present study aimed to valorize pea peels (Pisum sativum) using new unusual aspects. In other words, to identify and quantify the phenolic profile of pea peels 80 % ethanol extract (PEE), to estimate the antioxidant and anti-α-amylase activities of successive extraction solvent fractions of the previously mentioned extract, to evaluate chitosan(Cs) / polyvinyl alcohol (PVA) / PEE edible film as antioxidant agent. The results exposed that ethyl acetate fraction had the highest amounts  of  polyphenols and flavonoids where their values were 165.43 mg GAE/g and 26.63 mg QE/g ,respectively. Hesperidin was documented as the most abundant polyphenol in pea peels ethanolic extract with remarkably high amount (2017.2µg/g).  Butanol fraction recorded considerable anti-α-amylase activity (IC50 = 1.61 mg/ml).  The present study extremely evidenced the antioxidant activity of pea peel extracts. Besides , ethyl acetate fraction had the lowest  IC50 values for DPPH, NO and H2O2 assays with the values of 167.23, 302.36 and 317.66 μg/ml, respectively. Interestingly, a significant and negative correlation was remarked between total flavonoids content and IC50 for the scavenging DPPH radical. Finally , it could be suggested that Cs/PVA film containing PEE can be used for development of active food packaging materials.
