Comparison on Oil Yield of Phoenix dactylifera Seed Oil Extraction by Supercritical Carbon Dioxide and Solvent Extraction Method at 50°C

摘要

Oil yield extraction from Phoenix dactylifera seed was compared at 50°C based on highest oil yield results using supercritical carbon dioxide extraction method. The comparison was based on the efficiency of the method to extract high quality pure oil without addition of organic solvent. Time taken to extract the oil was also evaluated as part of the method's performance. Analysis of component in the oil was done using gas chromatography equipped with mass spectrometry (GC-MS). Oleic acid revealed to be the main fatty acid in Phoenix dactylifera seed oil, followed by palmitic acid, lauric acid, ascorbyl palmitate and others.
