Preparation and Quality Analysis of Orange Peel Oil Microcapsules
The process conditions for the preparation of orange peel oil microcapsules by spray drying are optimized by single factor and response surface tests,and the quality of the products prepared by freeze drying is compared with those prepared by freeze-drying method.The results show that the optimal conditions for the preparation of orange peel oil microcapsules by spray drying are as follows:air inlet temperature of 195℃,feed rate of 91.2 mL/min,and solid content of 34.7%.Comparing the products prepared by this method with the freeze-drying method,it is found that the capsules prepared by the spray drying method has a regular spherical structure,delicate hand feel,dense cyst wall and high embedding efficiency,good heat resistance and higher applicability.
