摘要
研究了无水乙醇、丙三醇和1、2-丙二醇3种助表面活性剂的种类及含量对核桃油微乳制备的影响,并测定了核桃油微乳体系的水、油渗滤阈值。在此基础上,通过单因素设计对核桃油微乳体系的水、油渗滤阈值进行预测。结果表明:3种助表面活性剂形成微乳区域按由大到小依次为无水乙醇>1、2-丙二醇>丙三醇;随着无水乙醇含量的增加,所形成微乳区域逐渐增大,以核桃油∶无水乙醇=1∶3时形成微乳区域最大,此时核桃油微乳水、油渗滤阈值分别为40%和70%,对应的剪切黏度和电导率值分别为7.52 Pa·s和270μS/cm;单因素设计预测的核桃油微乳水、油渗滤阈值分别为40.72%和69.53%,对应的剪切黏度和电导率值分别为7.51Pa·s和271.40μS/cm,因而得出结论:单因素设计能精确地预测核桃油微乳体系的水、油渗滤阈值。
In this paper, the effects of the kinds and contents of three kinds of cosurfactants - anhydrous ethano, glycerol and 1,2 propylene glycol on the preparation of walnut oil microemulsion were studied and the water/oil percolation threshold values of the walnut oil microemulsion were determined. On that basis, we also predicted the water/oil percolation threshold values of walnut oil microemulsion with single - factor design. The results showed that the microemulsion area of walnut oil microemulsion prepared with these three cosurfactants from big to small was anhydrous ethanol 〉 1,2 propylene glycol 〉 glycerol. With the increasement of anhydrous ethanol, the microemulsion area of the walnut oil microemulsion increased gradually. When walnut oil: anhydrous ethanol = 1 : 3, the microemulsion area of the walnut oil microemulsion was the largest, the corresponding water/ell percolation threshold values of walnut oil microemulsion were 40% and 70% respectively and the corresponding shear viscosity and conductivity values were 7.52 Pa · S and 270 μS/cm respectively. The prediction values of single - factor design for the water/oil percolation threshold values of walnut oil microemulsion were 40.72% and 69.53% respectively, the corresponding shear viscosity and conductivity values were 7.51 Pa · S and 271.40 μS/cm respectively. The single -factor design can accurately predict the water/oil percolation threshold values of walnut oil micloemulsion system.
