摘　　要：为制备油茶籽油微乳,采用伪三元相图法研究了不同乳化剂和助乳化剂、水与助乳化剂(W/A)质量比对油茶籽油微乳区面积的影响,并采用单因素实验建立油茶籽油微乳黏度与电导率随W/A添加量变化的模型,对油茶籽油微乳的水、油渗滤阈值进行预测。结果表明:油茶籽油微乳的最佳配方为乳化剂Tween80、助乳化剂丙三醇、W/A质量比1∶1;模型预测油茶籽油微乳的水、油渗滤阈值(W/A添加量)分别为40.75%、74%,对应的黏度、电导率分别为6 325.3 m Pa·s、86.166μS/cm。For the preparation of oil - tea camellia seed oil microemulsion, pseudo - ternary phasediagrams was used to study the effects of different types of emulsifiers and co - emulsifiers, and mass ratioof water to co - emulsifier （W/A） on the area of microemulsion region. Based on this, the models ofviscosity and conductivity of oil - tea camellia seed oil microemulsion changing with dosage of W/A wereestablished by single factor experiment, and the percolation thresholds of water and oil were predicted.The results showed that the best formula for oil -tea camellia seed oil microemulsion were obtained asfollows ： using Tween80 as emulsifier, using glycerol as co - emulsifier and W/A mass ratio 1 ： 1. Thepercolation thresholds of water and oil （ dosage of W/A） predicted by the models were 40.75% and 74%respectively, and the corresponding viscosity and conductivity were 6 325.3 mPa · s and 86. 166 IxS/cmrespectively.
