dc.description.abstractRowanberry pomace lipids were extracted with supercritical CO2 (42.4 MPa, 53 °C) using 3-7% of a co-solvent ethanol and fractionated by reducing 1st separator’s (S1) pressure to 7 MPa and cooling to 0, -10 and -20 °C for precipitating ‘heavier’ fraction (HF). The second separator (S2) was depressurized at ambient temperature for collecting ‘lighter’ fraction (LF). The yield of LF increased by decreasing S1 temperature and increasing the amount of a co-solvent. The concentration of β-carotene increased in LF by decreasing S1 temperature and increasing co-solvent concentration; at -20 °C it was by 66.7% higher than in the non-fractionated extract. The concentrations of tocopherols and phytosterols were also remarkably higher in LF. In total, 62 compounds were identified in the headspace volatile fraction of LF, benzaldehyde and benzyl alcohol being the most abundant constituents. In conclusion, fractionation enabled obtaining the fractions with the higher concentration of selected lipophilic rowanberry constituents.eng
