Abstract: Cinnamon oil is a kind of volatile oil component separated from cinnamon or cassia twigs. Its application in solution environment is limited by its poor water solubility and volatility. Thus, Cinnamon oil is prepared into emulsion in this study to improve its stability and water dispersivity. Firstly, centrifugal stability is taken as the evaluation index, and the suitable range of oil phase proportion, emulsifier and stabilizer dosage in emulsion prescription is determined through single factor screening. Then, the optimum formulation of Cinnamon oil emulsion is determined by orthogonal design with the retention rate of centrifugal emulsion as the evaluation index. In the optimal formulation, the mass ratio of Cinnamon oil, emulsifier Tween-80 and stabilizer xanthan gum is 10%, 2.0% and 1.5%, respectively. Under the optimal formulation, Cinnamon oil emulsion could be prepared with favorable stability and homogeneity. This study provides the basis for further application of Cinnamon oil emulsion.
