Isolation of Tomato Seed Oil From Tomato Waste by Application of Supercritical Fluid CO2 Extraction

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 influence 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 influence of operating parameters on total yield of extracted tomato seed oil are presented graphically. The influence of the supercritical fluid’ 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.
