摘　　要：通过离心法、分光光度计法、电导率法证明了辛烯基琥珀酸淀粉酯具有良好的乳化性和乳化稳定性。以低黏度辛烯基琥珀酸淀粉酯为乳化剂,以大豆油为乳化对象,利用激光粒度仪和光学显微镜探讨了均质转速、均质温度、均质时间、均质pH对辛烯基琥珀酸淀粉酯制备的乳化体系粒径的影响。结果表明:均质pH对乳化体系粒径具有显著的影响;均质时间越长和均质转速越大,乳化体系的粒径越小;均质温度对乳化体系粒径影响较小。Octenyl succinic anhydride modified starch （OSA starch） was proved to have good emulsibility and emulsion stability by centrifugation method, spectrophotometer method and conductivity method. Then the effects of homogeneous conditions （ speed, temperature, time, pH） on the particle size of emul- sion system prepared by OSA starch were investigated by Malvin 2000 particle analyzer and optical micro- scope, taking low viscosity OSA starch as emulsifier, and soybean oil as emulsion object. The results showed that homogeneous pH had a significant effect on the particle size of the emulsion system. With the homogeneous time prolonging and homogeneous speed increasing, the particle size of the emulsion system was small. In addition, homogeneous temperature had little effect on the particle size of the emulsion.
