Abstract: The goal of this work is isolation of tomato seed oil from the tomato waste (skin and seed) from tomato processing industry by utilization of non-conventional, green solvent technology. In the frames of experimental research, the infl uence of working parameters (temperature, pressure and extraction time) on the total yield of isolated tomato seed oil. Dynamic method for determination of solubility parameter in a supercritical CO2 has been used to determine the solubility of tomato seed oil in the supercritical CO2.

Obtained results regarding the infl uence of operating parameters on total yield of extracted tomato seed oil are presented graphically. The infl uence of the supercritical fl uid' density on the tomato seed oil' solubility was determined based on those results. The chemical composition of isolated tomato seed oil was determined by application of Gas Chromatography.

Keywords: tomato seed oil, solubility, supercritical CO2
