Abstract
Recovery of oil and carotenes from palm oil mill effluent (POME) was investigated in this paper. Solvent extraction was used to recover the residual oil from POME on a batch basis and silica-based resin was used in the column chromatography to separate the carotenes from the recovered oil. Residual oil extracted from POME in this study was 1710 mg/L by using petroleum ether and 3280 mg/L by using n-hexane in a single stage of solvent extraction. The carotene content in it was about 400 ppm. Carotenes from the recovered oil was then separated to α-carotene and β-carotene at a concentration of about 1450 ppm by column chromatography. The major components of recovered oil from POME were similar to the crude palm oil, which contained mainly α-carotene and β-carotene.
