Abstract:This paper is a research into the method，using Tween-80，ten polyglycerol monostearate as an emulsifier separate or compound after adding 95%ethanol to make fructus Schisandra chinensis pressure oil emulsion respectively.Evaluate the effects of emulsification according to the particle size and distribution of emulsion.The results showed that after mixing Twain-80，polyglycerol monostearate，oil as 2∶2∶10 ratio，and adding 95%ethanol，the smallest grain and the best effect of emulsifying can be obtained.The median diameter was 0.499μm and mean radius per unit volume was 0.502 μm.This paper also studied that emulsion was under the following conditions，such as placed in 8 d，heat，NaCl，and fructus Schisandra chinensis polysaccharides which impact on the stability of emulsion，the results showed that emulsion placed 8 d had no effect on the stability；fructus Schisandra chinensis polysaccharides could enlarges particle size，and stability became poor.Concentration of NaCl less than 1%，the emulsion particle size and range of the carbon was decreased. When concentration of NaCl was greater than 1%，particle size of emulsifier grew with increase of concentration of NaCl.
