Abstract

Silver nanoparticles (AgNPs) have been the focus of research in terms of catalyst, antimicrobial, and biomaterial production due to the potential of proteins, amino acid residues, free radical anions (antioxidants), and eukaryotic cell receptors. The synthesis of AgNPs using plant extracts such as leaf and papaya fruit is one of the safest nanoparticles and has a wide metabolite for reduction, so it is timely to apply to food packaging materials that have antioxidant activity. Initially, phytochemical compounds (phenolic and flavonoids) of papaya leaves and fruit were each extracted with air and ethanol solvents (1:0, 1:1, 0:1). The papaya leaf was selected as a better source of phytochemical compounds than papaya, while ethanol solvent was determined as the best solvent, based on analysis on plant extract (solids content, total phenolic, total flavonoids, antioxidant activity), and on AgNPs synthesis analysis (yield, level of inhibition, and characteristics of AgNPs) with successive results of 1.52%, 659.65 mg GAE/g, 614.04 mg QE/g, 130.3 ppm, 15.76%, 82.44%, and morphology according to nanoparticle criteria (round; 97.92 nm [SEM]; 79.92 nm [PSA]). AgNPs were selected then homogenized with AgNPs nanoparticles (0.0, 0.4, 0.6, 0.8, 1.0%). The addition of 1% nanoparticles gave the best characteristics of free radical resistant packaging films (4.5% starch and 1.5% glycerol), 1.52 MPa tensile strength, 22.37% elongation, and 18.94% free radical inhibition (42 times greater than control).
