摘要
以阿拉伯胶、麦芽糊精为囊材,以进风温度、阿拉伯胶占总囊材质量百分比、壁芯比、固形物含量等为主要考察因素,以微囊维生素C(V C)包封率与收率为评价指标,优化沙棘果浆微囊喷雾干燥制备工艺;并检测微囊的水分含量、水分活度、微观结构、粒径分布、吸湿性、稳定性等理化性质。优化的工艺条件为:进风温度为160℃,阿拉伯胶占总囊材质量百分比为80%,壁芯比为2∶1,固形物含量为20%。优化工艺下制备的沙棘果浆微囊具有较好的溶解性、稳定性,微囊V C包封率为95.48%,收率为57.14%。该研究可为沙棘果浆微囊及相关产品的开发提供参考。
With acacia gum and maltodextrin as capsule materials,the preparation process of sea buckthorn pulp microcapsules by spray drying was optimized and the encapsulation rate of vitamin c(V C)and microcapsule yield were taken evaluation index.The main factors including air intake temperature,acacia gum as a percentage of total capsule material,wall-to-core ratio and solid content were examined.The physicochemical properties of microcapsules such as water content,water activity,microstructure,particle size distribution,hygroscopicity and stability were also examined.The optimized process was as follows:inlet air temperature 160℃,acacia gum accounts for 80%,wall-to-core ratio 2∶1 and solid content 20%.The microcapsules prepared under optimized conditions had good solubility and stability,and the Vc encapsulation rate and yield was 95.48%and 57.14%,respectively.The research could provide a reference for the development of sea buckthorn pulp microcapsules and related products.
