| 摘 要： | 通过高效液相色谱精确计算乳状液载油率,并以载油率定量评价乳状液的稳定性;考察环境因素对乳状液稳定性的影响,发现乳状液最适pH为7,温度、离子浓度和游离OS浓度的增加均不利于乳状液稳定;利用响应面法拟合四个环境因素对VE复水后乳状液稳定性的作用,结果表明四个因素对载油率的贡献率依次为:温度>NaCl浓度>游离OS浓度>pH。

| Abstract: | A high-performance liquid (HPLC) chromatography method was established to analyze the oil load efficiency of VEemulsion, and the obtained data could be used to evaluate the stability of emulsion. The effect of pH, temperature, ion concentration and free-OS concentration on oil load efficiency of VEemulsion were examined. The results showed that the optimal pH was 7, and the stability of emulsions decreased along with the increasing temperature, ion concentration and free-OS concentration. Response surface methodology was further applied to study the formation of VEemulsion. And the relative degree of influence of all environmental factors on its oil load efficiency was that temperature>NaCl concentration>free-OS concentration>pH. |
