Abstract:
To minimise the food waste, this paper applied the antimicrobial plates produced from poly(butylene succinate) (PBS)/geraniol blend which was processed into two different microstructures. Experimental work was separated into three major parts. The first one was the determination of a suitable geraniol concentration by minimum inhibitory concentration and inhibitory clear zone techniques. After that a selected PBS/geraniol composition was then processed into the solid and porous antimicrobial plates of 15 mm in diameter and 2 mm in thickness. Finally, the solid and porous antimicrobial plates were inserted in bread package and evaluated the shelf-life extension performances. Experimental results indicated that a suitable geraniol composition was 8 wt%. Migration test confirmed that geraniol released from both solid and porous plates by more than 30 days. Shelf-life evaluation by counting the microorganisms indicated that applying antimicrobial plates in bread package was found to extend by around 5 and 10 days with solid and porous antimicrobial plates, respectively. In summary, both antimicrobial plates are possibly applied for bread shelf-life extension which easily inserts inside any food container. This is a practical use for retail and household stages. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
