Quality evaluation and storage stability of Akebia trifoliata var. australis seed oil microcapsules

The quality evaluation of Akebia trifoliata var.australis seed oil microcapsules was investigated.The initial storage stability of microencapsulated Akebia trifoliata var.australis seed oil was estimated by determining physicochemical properties.Results indicated that the moisture content and mean particle diameter of the microcapsules were 2.59% and 328.1 nm,respectively.The powder was exquisite and uniform with favorable solubility and dispersion.The microcapsules had a regular spherical shape with smooth surface and compact capsule wall through SEM analysis.DSC analysis demonstrated that the microcapsules had high glass-transition temperature and thermal melting temperature,which indicated good storage stability.Moreover,the encapsulation efficiency of the microcapsules changed a little after being stored for six months.Therefore,the Akebia trifoliata var.australis seed oil microcapsules had favorable product quality and good storage stability.
