【摘要】 目的:制备一种南极磷虾油微乳包埋方法并研究其稳定性。方法:以肉豆蔻酸异丙酯(IPM)为油相,Tween 80和Span 80复配表面活性剂相,乙醇为助表面活性剂,制备南极磷虾油油包水(W/O)型微乳液,并利用拟三元相图法考察各组分对微乳的影响。通过动态光散射法测定微乳液在离心试验、高温试验、盐度试验、贮藏试验中微乳液粒径大小变化,考察微乳液的稳定性。结果:在复配表面活性剂中,Tween 80和Span 80的质量比为6∶4,乙醇作为助表面活性剂且与表面活性剂质量比K_m=1.0时,得到稳定性良好的微乳液体系。结论 :该南极磷虾油微乳液制备简便,稳定性良好,是一种新型南极磷虾油的包埋方法。更多还原

【Abstract】 Objective: To prepare krill oil microemulsion and investigate its stability.Method: The W/O krill oil microemulsion was prepared by using IPM as the oil-phase solvent,Tween 80 and Span 80 as the surfactant phase,ethanol as the cosurfactant phase.The concentration and stability profile of krill oil in microemulsion were determined by pseudo-ternary phase diagrams.And the changes of diameter with the microemulsion in the centrifugal,elevated temperature,salinity,and preservation test were measured by Dynamic Light Scattering.Results: When the mass ratio of Tween 80 and Span 80 was 6∶4 and alcohol as cosurfactant,Km=1.0,can be obtained a microemulsion system with good stability.Conclusion: Microemulison is a new and convenient method to encapsulate krill oil with good stability.更多还原
