摘要
实验以乳化液粘度和包埋率为考察指标,通过单因素及正交实验,借助显微拍照、粒径分布分析,优化了油莎豆油微胶囊制备工艺。结果表明:选用辛烯基琥珀酸酯化淀粉HI-CAP100和麦芽糊精复配作为微胶囊化油莎豆油的壁材,油莎豆油微胶囊制备最优工艺为:壁材比(辛烯基琥珀酸酯化淀粉∶麦芽糊精)为1∶1,载油量为20%,干物质含量为40%,在此条件下,油莎豆油的微胶囊包埋率可达到77.62%,平均粒径为46.78μm。贮藏实验结果表明,微胶囊化油莎豆油的贮藏稳定性较好。
The Cyperus esculentus oil microcapsule preparation technology was optimized through single factor and orthogonal tests by means of microphotograph and particle size distribution analysis with emulsion viscosity and embedding rate as indexes.The results showed that combinations of starch octenylsuccinate HI-CAP100 and malt dextrin were used as wall material.The optimum process condition of micro-encapsulation preparation of Cyperus esculentus oil was wall material ratio（starch octenylsuccinate：malt dextrin）1：1,fuel load 20%,and dry matter content 40%.Under this condition,embedding rate could reach 77.62%.The average particle size of microencapsulation was 46.78μm.The result of the storage experiment showed that the microencapsulated Cyperus esculentus oil had characteristics of good stability.
