Abstract: This study investigated the phytochemical composition of soursop (Annona muricata) seeds and assessed their potential as a bioplastic material. Phytochemical screening confirmed the presence of alkaloids, flavonoids, tannins, phenolics, and saponins, which contribute to polymer formation and antimicrobial properties. Fourier Transform Infrared Spectroscopy (FTIR) analysis identified functional groups essential for biopolymer synthesis. A bioplastic film was developed using soursop seed extracts and tested for mechanical strength, biodegradability, and antimicrobial activity. The material exhibited moderate tensile strength and flexibility, demonstrating suitability for packaging applications. Biodegradability testing showed significant weight reduction over time, indicating environmental sustainability. Antimicrobial analysis revealed inhibition of Escherichia coli and Staphylococcus aureus, suggesting potential use in food preservation. Comparative analysis with conventional bioplastics confirmed the viability of soursop seed-based bioplastic as an eco-friendly alternative. The findings highlight the potential of agricultural by-products in biopolymer production, contributing to waste valorization and sustainable packaging solutions.
