Ck. Ooi et al., CONTINUOUS SUPERCRITICAL CARBON-DIOXIDE PROCESSING OF PALM OIL, Journal of the American Oil Chemists' Society, 73(2), 1996, pp. 233-237
Crude palm oil was processed by continuous supercritical carbon dioxid
e. The process reduces the contents of free fatty acids, monoglyceride
s and diglycerides, certain triglycerides, and some carotenes. The ref
ined palm oil from the process has less than 0.1% free fatty acids, hi
gher carotene content, and low diglycerides. Solubility of palm oil in
supercritical carbon dioxide increased with pressure. A co-solvent im
proves the refining process of palm oil.
