Abstract

The aim of this study was to optimize the extraction of chan seed oil by supercritical fluid as a function of pressure, temperature and extraction time using response surface methodology, and to evaluate its physicochemical properties and its quality. The optimal extraction conditions were 450 bar, 80 °C, and 193 min with an extraction yield of 9.21% and 62.36% recovery. The viscosity of the oil was 104.13 mPa s, and the activation energy was 2.104 kJ/mol; primary and secondary oxidation was 1.681 and 0.662. The quality of the oils was evaluated with saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), and unsaturated fatty acids (UFAs). They were also determined the atherogenicity (AI), (6.70–8.27) and thrombogenicity indices (TI), (0.075–0.094); and the hypocholesterolemic/hypercholesterolemic (HH) ratio, (19.12–33.84). The oils presented high content of fatty acids ω 3, 6, and 9, and the oxidizability was from 6.70 to 8.27, indicating good stability. The characteristics of the oil extracted were compared with the oil obtained conventionally.
