Abstract: Based on the single-factor experiments,orthogonal experiment was used to optimize the technical parameters for preparing Chaenomeles speciosa(Sweet) Nakai seed oil microcapsules and the optimum technical paramenters were as follows:homogeneous pressure 30 MPa,inlet temperature 190℃,feeding rate 16 mL/min.The microcapsules produced under these processing parameters were determined as canary yellow powders,with microencapsulation efficiency 83.59%,water content 2.51%,density 0.625 g/cm3,hygroscopicity 9.191%,and particle size 39.440 μm.The microcapsule powders observed by SEM were found to have regular spherical shape with smooth surface and compact structure.The results of storage stability study showed that the microcapsules were more stable against oxidation in air than the oil which was not entrapped.The properties of microcapsule products were excellent,and the shelf life of C.Speciosa seed oil was greatly extended.
