| 摘 要： | 目的制备鱼油微乳液并研究其特性。方法采用食用大豆油和丙三醇作为鱼油的油相溶剂,失水山梨醇油酸酯聚氧乙烯醚(Tween 80)和乳糖(9:1,w/w)为表面活性剂相,制备了O/W型鱼油微乳液。拟三元相图法考察了盐度和pH对微乳液区的影响,测定了鱼油微乳的电导率变化和粒径大小,研究了微乳液的流变特性。结果该鱼油微乳液具有较好的耐酸性和耐盐性,平均粒径在10～100 nm之间,稳定性良好。流变特性研究表明表面活性剂相和油相质量比为9∶1,含水量80%(w/w)的鱼油微乳液具有剪切变稀的流变行为,属于拟塑性流体。结论鱼油微乳液制备简便,稳定性良好,是包封鱼油的新方法。

| Abstract: | Objective To prepare fish oil microemulsion and investigate its properties.Methods The O/W fish oil microemulsion was prepared by using edible soybean oil and propanetriol as the oil-phase solvent,polyoxyethylene sorbitan monooleate(Tween 80) and lactose(9:1.w/w) as the surfactant phase.The effects of salinity and pH on the microemulsion region were determined with pseudo-ternary phase diagrams.The further investigations into conductivity,particle size and rheological characteristics of the microemulsion we... |
