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。
The conjugated linoleic acid ethyl ester was microemulsified with sodium dioctylsuccinate sulfonate (AOT) as surfactant and short chain alcohol, n-propanol and n-butanol as cosurfactants. The results show that the use of different structures of alcohols as cosurfactant affects the type of microemulsion formation, and different Km values (surfactant / co-surfactant) affect only the area of the microemulsion formed. The oxidation stability of conjugated linoleic acid ethyl ester and conjugated linoleic acid ethyl ester microemulsion was compared. The results showed that microemulsion had better anti-oxidation ability, solubilized into 0.1% VC and 0.1% VE Greatly improve the oxidation stability of the product.
