Original Abstract
In this paper, relatively new spectroscopic methods were used for investigation of edible oils and their thermal degradation. There were included the samples of refined rapeseed and sunflower oil and the same oils heated for specified time interval at the temperature 200 deg. Celsius. The optical characteristics of oils have been investigated with Terahertz Time Domain Spectroscopy (THz-TDS). The refractive indices were calculated in the specified terahertz frequency range, processed and statistically evaluated. The Wilcoxon matched pairs test was carried out for comparison of unheated and heated oil samples. The results measured by THz-TDS were supplemented by Raman spectra analysis. Both methods seem to be capable analyzing tool for oil investigation.
