| 中文摘要: |
| 研究了深海鱼油纳米乳的制备方法，并对制备的纳米乳的理化性质进行了分析。以深海鱼油为油相，采用表面活性剂复配法从Span-20、Span-80、Tween-20、Tween-80中筛选合适的乳化剂。结果表明：以Span-80和Tween-80体积比为19∶?81的混合液作为乳化剂，以无水乙醇为助表面活性剂；当V(混合表面活性剂)∶?V（深海鱼油）∶?V（蒸馏水）=8∶?2∶?20时，所制备纳米乳为O/W型，其表观澄清透明，粒径范围在7~25 nm之间，多分散系数(PDI)范围在0.15~0.25之间。用三相图表示纳米乳的成乳范围。稳定性试验表明所制备的纳米乳离心后能保持稳定，但对高温不耐受，需25?℃以下保存。 |

| The preparation method of deep sea fish oil nanoemulsion was investigated, and the physicochemical properties of the prepared nanoemulsion were measured. The deep sea fish oil was used as oil phase, and the proper emulsifier was screened from Span-20, Span-80, Tween-20 and Tween-80 by surfactant combination method. The results showed that with mixture of Span-80 and Tween-80 with volume ratio 19∶?81 as emulsifier and anhydrous ethanol as cosurfactant, when the volume ratio of mixed surfactant to deep sea fish oil and distilled water was 8∶?2∶?20, the prepared nanoemulsion was O/W type, apparent clear and transparent, the particle size ranged from 7 nm to 25 nm, and the polydispersity index (PDI) ranged from 0.15 to 0.25.The milk emulsion range of nanoemulsion was indicated by three phase diagram. The stability test results showed that the prepared nanoemulsion could keep stable after being centrifuged and unstable at high temperature, so it needed to be stored below 25?℃。 |
