摘 要：
以二辛基琥珀酸磺酸钠(AOT)为表面活性剂,短链醇乙醇、正丙醇、正丁醇为助表面活性剂,对共轭亚油酸乙酯进行了微乳化实验。结果表明,使用不同结构的醇做助表面活性剂会影响微乳液形成的类型,而不同的Km值(表面活性剂/助表面活性剂)只影响所形成微乳液的面积。比较了共轭亚油酸乙酯和共轭亚油酸乙酯微乳液的氧化稳定性,结果证明微乳液的抗氧化能力更好,向其中增溶进0.1%的VC和0.1%的VE将大大提升产品的氧化稳定性。

摘 要：
The formation conditions and phase behaviors of conjugated linoleic acid ethyl ester (CLAEE) microemulsion were studied. Aerosol-OT (AOT) was used as surfactant, and several short chain alcohols (i.e. ethanol, n-propanol, and n-butanol) were investigated as cosurfactants. The results showed that different structures of alcohols used as surfactants can form different types of microemulsion, but different values of Km (surfacant/cosurfactant) can only affect the thus-formed microemulsion area. Comparing the oxidative stability of CLAEE, with that of CLAEE microemulsion sees an outstanding rise, in a better resistance to oxidation of the latter. Hence the practice of adding 0.1% vitamin C (VC) and 0.1% vitamin E (VE) into the CLAEE microemulsion can further increase the oxidative stability of the products.
