Using terahertz wave time-domain spectroscopy systemwe measured the terahertz wave time-domain spectroscopy of the corn oil between 0.2 and 1.4 THz. Taking care of the effect of the utensilwe employed a novel iterative algorithm to analyze the optical properties of the corn oil. In contrast to most of the published experimentsthe iterative algorithm further improves the accuracy of the parameter extraction, and we are able to reliably investigate the samples. The results show that the novel calculating method provides a guidance for detecting the quality of seed oils.
