Preparation and Storage Stability of Peony Seed Oil Microcapsules
摘要
Abstract
[Objective]To prepare peony seed oil microcapsules by spray freeze drying method and study its immune enhancement activity.[Method]Taking yembedding rate as index,basis on the single factor test,the technological conditions of preparing peony seed oil microcapsuleswere by spray freeze-drying method were optimized by orthogonal test method.In addition,the storage stability of peony seed oil microcapsules at 25℃were studied.[Result]The optimized process conditions for peony seed oil microcapsules were homogenization pressure 40 MPa,vacuum pressure 40 Pa,and cold air volume 5.5 m3/min.Under these conditions,three repeated experiments were conducted,and the embedding rate reached 96.34%.After microencapsulation,the peroxide value and acid value increase rate of peony seed oil decrease.[Conclusion]The spray freeze drying method is a suitable method for preparing the peony seed oil microcapsules and the peony seed oil microcapsules has a high storage stability.关键词
