摘要：Instead of applying the glycerol coating method, the sample surface of a plastic food case was dipped with castor oil-ethanol solution (3%) and evaporated the solvent. Glass beads (50-75 mesh) stuck uniformly to the surface. As the glass beads weight was proportional to the surface area, the surface area could be determined by weighing the stuck glass beads. Spherical glass beads could be commercially obtained with ease and showed the good sticking ability. The accuracy and reproducibility of this method under several conditions were satisfactory. This method was suitable to determine the surface area of various plastic food cases.
