锐孔-凝固浴法制备硫苷粗提物微胶囊的研究

摘要

In this paper, orifice-coagulation bath method was applied for preparation of glucosinolate crude extract microcapsules. The effects of preparation conditions on glucosinolate crude extract for encapsulation ef-ficiency were estimated, and the optimal conditions for the preparation of microcapsules were identified. Rape-seed oil was the middle oil phase, sodium alginate concentration was 2%, calcium chloride concentration was 2%, the curing time was 15min, Span 80 was 10%, Tween80 was 6%, the ratio of initial emulsion and outer aqueous solution was 1∶4, and the ratio of the volume of inner aqueous and oil phase was 4. These microcap-sules of glucosinolate crude extract had high encapsulation efficiency and uniform particle size.%采用锐孔－凝固浴法制备硫苷粗提物微胶囊，研究制备条件对硫苷粗提物包埋率的影响，确定微胶囊制备的最优条件：菜籽油作为中间油相，海藻酸钠浓度2%，氯化钙浓度2%，固化时间15 min，Span 8010%，Tween 806%，初乳中内水相与中间菜籽油的比为1∶4（体积比），外水相与上述混合初乳比值为4，制备的微胶囊对硫苷粗提物的包埋率较高，粒径均一。
