油茶籽油微乳的制备及其性质研究

摘要

For the preparation of oil-tea camellia seed oil microemulsion,pseudo-ternary phase diagrams was used to study the effects of different types of emulsifiers and co-emulsifiers,and mass ratio of water to co-emulsifier (W/A) on the area of microemulsion region.Based on this,the models of viscosity and conductivity of oil-tea camellia seed oil microemulsion changing with dosage of W/A were established 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 as follows:using Tween80 as emulsifier,using glycerol as co-emulsifier and W/A mass ratio 1 ∶ 1.The percolation 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 μS/cm respectively.%为制备油荼籽油微乳,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荼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 mPa·s、86.166μS/cm.
