Abstract :
In this paper, the extraction of palm kernel oil from palm kernel cake and candlenut samples after being used was studied. Supercritical fluid (SC-CO2) at pressure of 7.28 MPa and temperature 31°C was examined and tested. The obtained results indicated that the increase in particle size, pressure and temperature enhanced the oil solubility. The supercritical carbon dioxide extraction at optimized parameters resulted in oil yield extraction of 46.4% at solubility of 9.6 g oil/kg CO2. The obtained candlenut oil from supercritical carbon dioxide extraction has better oil quality than oil which was extracted by Soxhlet extraction using n-hexane solvent. The oil contains high unsaturated oil (linoleic acid and linolenic acid), which have many beneficial effects on human health.
