Abstract: | Palm carotene was successfully concentrated from crude palm oil (CPO) by an adsorption process using a synthetic adsorbent
followed by solvent extraction. Evaluation of feed CPO and CPO which underwent the carotene extraction process was conducted.
The quality of CPO after the extraction process was slightly deteriorated in terms of free fatty acid, moisture content, impurities,
peroxide value, anisidine value, discriminant function, and deterioration of bleachability index. However, the CPO still can
be refined to produce refined, bleached, deodorized palm oil that meets the Palm Oil Refiners Association of Malaysia specifications.
No extra cost was incurred by refining this CPO as the dosage of bleaching earth used was very similar to the refining of
standard CPO. The triglyceride carbon number and fatty acid composition of CPO after going through the carotene extraction
process were almost the same as CPO data. The major components of the carotene fraction were similar to CPO, which contains
mainly α- and β-carotene. The carotene could be stored for at least 3 mon. |
