The effect of kaffir lime (Citrus hystrix DC) essential oil on bioplastic derived from cassava peel waste

Kaffir lime essential oil is reported contain a biologically active secondary metabolite from the class of terpenoid. It was reported active as antibacterial, antioxidant, and anticancer. Combination of this bioactive essential oil to afford bioplastic or biodegradable plastic will open their future applications in industry and medicine. This paper report the characteristic of the combining of kaffir lime essential with starch from cassava peel waste to produce bioplastic. The FTIR spectroscopy, SEM, XRD and elasticity test was reported to the bioplastic produced. In short, bioplastic prepared from both starting materials are able to be made. The appearance is clear and transparent. The FTIR spectra also provide a combination of both functional groups, and some fractures found to the bioplastic without addition of kaffir lime essential oil. Interestingly, elasticity improves for bioplastic composed of essential oil.
