  • How is rapeseed oil extracted?
  • The extraction of the seed oil was done in triplicate. The oil content of the seeds was 40.9 ± 0.1%. The rapeseed oil was obtained using an oil screw press (Model SPU 20, Elektromotor-Šimon, Senta, Serbia) using various nozzle diameters (8–12 mm), temperatures of the press head (40–80 °C), and screw frequencies (40–60 Hz).
  • Can mechanical pressing be used for rapeseed oil extraction?
  • The investigation of mechanical pressing for rapeseed oil extraction has been limited. In one study, a screw-pressing method achieved an extraction degree of 72% [ 16 ]. Another study using a 'duo' screw press demonstrated a higher extraction degree of 82.6% [ 17 ].
  • What is the mass flow rate of pressed rapeseed oil?
  • The temperature of the pressed oil at the exit from the press was 40 °C. The mass flow rate of the press cake and pressed rapeseed oil under these pressing conditions were 174 ± 22 g/min and 52.7 ± 0.1 g/min, respectively. Optimization of screw-pressing process factors can involve the oil recovery yield or quality properties.
  • How is pressed rapeseed oil yield analyzed?
  • Experimentally obtained values of the pressed rapeseed oil yield were analyzed by the RSM, which includes the nonlinear regression method to define the extended quadratic equation and the ANOVA to evaluate the significance of the developed model, the individual factors, interactions, and the goodness of fit at a 95% confidence level.
