【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。更多还原

【Abstract】 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 / oil 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 microemulsion system.更多还原
