제목 Encapsulation of Oil into Water-Soluble Polymer fibers by Electrohydrodynamic Jetting
초록 Encapsulation is an important technique being used to protect sensitive active materials. The essential oil and organic extracts of Zizyphus jujube, which is sensitive to the environmental stimuli, have antimicrobial efficacy against food-borne pathogens. In this study, essential oil-loaded PVA fibers were prepared using an electrospinning technique. A co-axial electrospray process was developed to encapsulate immisible liquids located in each inner and outer nozzle. Microfibers of approximately 2 μm were observed by a scanning electron microscope. Confocal laser scanning microscope images showed that oil was distributed evenly in the microfibers. Entrapment of oil in the core-shell structure is expected to slow down the release of volatiles and guarantee more protection for oil against atmospheric conditions. This method may have a potential application in different types of food or pharmaceutical products where maximum protection for flavours or sustained release is required.
