3.1.3. Comparison of different extraction
The oil characteristics and yields of the aforementioned five methods are compared in this paper. The conditions of extractions,such as temperature, time, pressure and solvent, are all different (Table 1). Hexane is used in SE and MAE, and water is used in AEE and MAEE. In SFE, supercritical state CO2 is used as the solvent. Table 1 shows that the yield of the kernel oil is 6.13 wt/wt% by SE and 5.54 wt/wt% by SFE. MAE and AEE give yields of 6.63 wt/wt% and 6.94 wt/wt%, respectively. MAEE is therefore the best method giving the highest oil yield (7.78 wt/wt%). MAE is the fastest of the various methods studies.
