Mangifera indica seed particulates as a sustainable natural antibacterial filler for biofilms: a comprehensive characterization

Biocomposites serve as a promising alternative to traditional plastic materials. To develop such a biocomposite, Mangifera indica (mango) seed particulate (MSP) was subjected to reinforcement compatibility analysis. The MSPs were crushed down to 221.3 nm particulates through the ball milling process. The finely powdered MSP had a cellulose content of 79.48%, a hemicellulose content of 37.69%, a lignin content of 10.41%, and a pectin content of 8.08%. The morphological surface analysis showed the porosity in MSP, and it can help it bind with matrix materials. The thermal resistance of MSP is up to 354 ºC, as revealed by thermogravimetric analysis. To evaluate its competency with polymer, MSP was integrated with polyvinyl alcohol (PVA) through the solution casting method. The results of MSP in the PVA biopolymer show its potential to act as a sustainable filler material for fabricating biomedical composite materials along with PVA and other similar biopolymers.
