[Method] Using [5-cyclodextrin, Arabic gum and soy protein as the wall materials and by the preparation technology of peony oil through spray drying, we conducted single factor experiments and orthogonal experiment analysis of the tech- nical parameters of peony oil microencapsulation. [Result] The optimal parameters of peony oil microcapsule preparation were acquired. The ratio of three wall materials （~5-cyclodextrin, Arabic gum, and soy protein） is 3：1：2, the solid content is 35%, the ratio of core-wall material is 3：1, emulsifier dosage is 0.2%, and the embedding rate of peony oil reaches 92%. [Conclusion] This technology produced the highest em- bedding rate and it laid the foundation for further development of peony oil.展开更多
