Supercritical-fluid extraction of oil-palm components
Residue from the mechanical processing of palm oil was treated with supercritical-fluid extraction (SFE) to extract carotenes. This was done at different extraction conditions. Also, leaves of palm oil trees were extracted using supercritical fluid to gain high concentrations of tocopherols in the extract. The aim of these SFE experiments was to evaluate whether either the carotene or tocopherol contents of the extracts were sufficiently high enough to allow downstream processing of these waste products. In addition, solubility data for α-tocopherol in supercritical carbon dioxide in a density range of 220-930 kg m-3 were measured. © 1995.
