In this study, it was prepared PCL microcapsules consisted of lemongrass oil as core material by solvent evaporation method. The effects of concentration of core material, shell material, emulsifier and stirring rates on the preparing of the microcapsules were investigated. It was confirmed that lemongras oil has been encapsulated into PCL microcapsules by FT-IR. The size and form of the microcapsules was observed by SEM. The average particle size of microcapsules was confirmed by PSA. Entrapment efficiency and release behavior of the microcapsules was observed by UV-Vis absorbance. |
