Objective:To evaluate properties of solidifying volatile oil from Cinnamomum cassia with porous starch. Method: Volatile oil from C. cassia was solidified by porous starch

Effect of different dosages of porous starch on yield of cinnamaldehyde

in vitro dissolution and thermal stability;Physical characterization of solidified powder was characterized by scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). Result: Yield of cinnamaldehyde was up to 92.6%

when solidification ratio of porous starch to volatile oil was 2∶1; Dissolution rate of cinnamaldehyde increasesd and its thermal stability improved after volatile oil from C. cassia was solidified. Conclusion: Production technology of solidifying volatile oil from C. cassia by porous starch was simple and convenient operation with high application value.
