The ginger essential oil/beta-cyclodextrin (GEO/beta-CD) composite, ginger essential oil/beta-cyclodextrin/chitosan (GEO/beta-CD/CTS) particles and ginger essential oil/beta-cyclodextrin/chitosan (GEO/beta-CD/CTS) microsphere were prepared with the methods of inclusion, ionic gelation and spray drying. Their properties were studied by using scanning electron microscopy (SEM), differential scanning calorimetry (DSC), thermo-gravimetry analysis (TGA), Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). The results showed that the particle size of GEO/beta-CD composite was smaller than that of beta-CD and GEO/beta-CD/CTS particles were loose and porous, while the microsphere obtained by spray drying had certain cohesiveness and small particle size. Besides, results also indicated that beta-CD/CTS could modify properties and improve the thermal stability of GEO, which would improve its application value in food and medical industries.
