Extraction of Value-Added Products from Empty Fruit Bunch by Using Supercritical CO2 and Water as Co – Solvent

Recently, about 34.44 million tonne of oil palm biomass was produced in Malaysia
with empty fruit bunch (EFB) as major compounds. This is due to the high market
demand for palm oil in the world. The value-added products which are phenolic
compounds and fatty acids from EFB were extracted using supercritical carbon
dioxide (Sc-CO2) and water as co-solvent. This is because Sc-CO2 extraction is a
feasible and environmental friendly technology. In this study, Sc-CO2 extraction of
EFB was carried out under several experimental parameters such as temperature,
pressure and particles size that varies in the range of 40 - 90°C, 20 - 40 MPa and 0.15
mm - 2.20 mm, respectively.
