摘要: 本文研究以大豆分离蛋白、麦芽糊精与葵花籽油、乳化剂等作为双层壁材,采用双乳化-喷雾干燥法制备双层原花青素微胶囊。采用三因子单形重心法优化壁材的最佳配比,确定了制备双层原花青素微胶囊的最佳工艺条件:均质压力40MPa,进风温度195~200℃,进料速度45ml/min。用此工艺制备的双层微胶囊包埋率高,结构理想,稳定性好。

Abstract: This paper studied the procyanidins double-coated microencapsulating technology by double emulsion-spray drying, using soybean protein isolated, malt dextrin, sunflower seed oil, emulsifier et al. as wall material. The optimum proportion of wall material was determined by using three-factor single shape barycenter method. The results showed that the optimum spray-drying parameters are as follows: the homogenizing pressure 40MPa, the inlet air temperature 195~200℃ and the feeding speed 45ml/min. The bilayered microencapsulation shows good structure and stability.
