Abstract
Cinnamon essential oil (CEO) is a natural antimicrobial being investigated for food packaging as a substitute for synthetic chemicals due to consumer concerns over food safety. In this study, lactic acid poly (PLA) and chitosan were successfully modified with essential oil (CEO) at concentrations (1.5%, 2%, 2.5%, and 3% v / v) that formed composite fibres with using a simple electrospinning method. The morphology of the composite fibres can be seen from PLA / CS-CEO-2.5 showing good stability of the CEO so that the antimicrobial activity is increased compared to other blends. PLA / CS-CEO fibre shows a high level of long-term inactivation against Escherichia coli and Staphylococcus aureus due to the CEOs ongoing release, indicating that advanced PLA / CS-CEO fibres have great potential for active food packaging applications
