PALM CAROTENE CONCENTRATES FROM CRUDE PALM OIL USING VACUUM LIQUID CHROMATOGRAPHY ON SILICA GEL

BONNIE TAY Yen Ping*

ABSTRACT

Palm carotene was concentrated from crude palm oil by vacuum liquid column chromatography using a commercially available adsorbent silica gel. Two products were produced, palm carotene in oil-based and carotene-depleted oil. The highest carotene concentrates (> 10%) was achieved using a ratio of 1:10 (w/w) crude palm oil:silica gel. For this ratio, activated silica gel improved the carotene recovery to 72%- 92% compared to 21% –32% by non-activated silica gel. High recovery (99%-99.5%) of the bulk oil recovered from the silica gel was achieved by elution with a polar solvent, e.g. ethanol or 2-isopropanol, followed by a non-polar solvent, e.g. hexane
