Abstract
Abstract
Annually, amounts of orange waste are directed into the environment. The orange waste oil is a potential source of compounds of interest and alternatives have been explored to highlight their potential. Appropriately, this study investigated the effects of oil extraction processes involving pressurized liquids (PLE) and supercritical CO2 (SC-CO2) on orange residues. The results were compared with the standard Soxhlet procedure. The optimization of the operational parameters was established based on the adjustment of different process conditions for pressure (150 and 350 bar), extraction time (20 and 60 min), and temperature (40 and 60 °C). The results indicated that the maximum oil yields for orange peel and pomace were 37.76 % and 43.39 %, respectively, for the PLE approach. The SC-CO2 expressed maximum yields of up to 0.50 % and 0.38 % for peel and pomace, respectively. The GC-MS analysis reported the concentration of bioactive compounds after the distinct extraction methods.
