| 摘 要： | 本文研究比色法测定油脂酸价,为了避免使用昂贵的表面活性剂双-(2-乙基己基)磺基丁二酸钠,采用振荡离心操作方法。通过和国标法比较测定红花籽油,葵花籽油和玉米油三种油脂酸值,结果表明,比色法和国标法的精密度相似,两者之间相对误差分别为30.0%,15.3%和9.1%。

| Abstract: | The determination of acid value of oils by colorimetric method was studied. To avoid the use of expensive surfactant bis(2-ethylhexyl) sulfosuccinate,vortex and centrifugation were used. By comparison between the nation standard method and the colorimetric methods for the determination of acid value of safflower oil,sunflower oil and corn oil,it is clear that the two methods had similar precision and the relative error between them was 30.0%,15.3% and 9.1% respectively. |
