This study shows the potential inorganic materials as carrier of perilla frutescens essential oil (PFE) into composites. To prepare the perilla frutescens composites (PFC), inorganic materials such as coral-calcium, montmorillonite K10, montmorillonite k30, goethite was mixed respectively with PFE in a ratio of 1:1.5 and place on an orbital-shaker set at 300rpm at room temperature. The properties of the different inorganic materials containing PFE by supercritical carbon dioxide extraction system were characterized thermogravimetric analysis (TGA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effect of carrier composite to the thermal stability of the prepared composites were studied by TGA and the PFE loaded montmorillonite K10 increased the thermal stability of the essential oil. The characterization of carrier composites by XRD and SEM showed that PFE is contained in the composite. |
