Mechanical and Antibacterial Properties of Chitosan-PLA Film Containing Cinnamon and Ginger Essential Oil for Milkfish Satay Packaging

In this study the effect of Chitosan-PLA (CH-PLA) film enriching with cinnamon essential oil (CEO) and ginger essential oil (GEO) were analyzed to investigate the mechanical and antibacterial properties. Resulting were improved the tensile strength (TS) effect of CEO and GEO addition to CH-PLA film by decrease about 47.39% for CEO and 66.85% for GEO compared to the film without essential oil. Blending CEO and GEO into CH-PLA film can also increase with increasing essential oil. CEO and GEO oil can increase 2.95 and 2.9 of elongation percentage compared to the film without essential oil on 2%of essential oil. CH-PLA film containing additional of CEO and GEO had no important effect on the CH-PLA film thickness. The film thickness for each essential oil composition varied from 0.10 to 0.13 m, while CH-PLA film containing CEO and GEO decrease total weight loss and bacterial population of milkfish satay compared with uncoated and coated without EO milkfish satay.
