IMPACT OF DIFFERENT EXTRACTION METHODS ON PHYSICAL CHEMISTRY PROPERTIES OF PALM KERNEL OIL (ELAEISGUINEENSIS)
Abstrak: This study was
conducted to assess the impact of oil extraction from kernel palm by two
methods of extraction they are, mechanical press and solvent (hexane)
extraction. The aim of this study was to determine the impact of extraction
methods on physical chemistry properties of palm Elaeisguineensis kernel oil.
Methods were used for extracting oil from palm kernel according to the method
of Mandal and Lee, moreover physical chemistry analysis for oils was conducted
by AOAC and AOCS methods. These results showed significant differences
(P<0.05) of the extraction method between five physical chemistry
parameters. In these results number of saponification, peroxide, and iodine of
oil that was extracted by hexane, while density was extracted mechanically and
the results showed significant difference with the standards of FAO and WHO.
The results showed that the number of each parameter from solvent (hexane) and
mechanical press are Saponification 194.29±0.20 mgKOH/g and 215.74±1.29
mgKOH/g, Peroxide 3.72±0.25 mgKOH/g and 3.39±0.31 mgKOH/g, Iodine 18.28±0.13
mgKOH/g and 22.8±0.23 mgKOH/g, Density 0.87±0.01 g/cm3 and 0.91±0.00 g/cm3,
Viscosity 27.66±1.15 mm2/s and 40.66±2.08 mm2/s, FFA 1.33±0.17% and 1.83±0.04%,
respectively. The color of the oil were clear yellow by hexane extract and
brown by mechanical extract. These results showed that the extraction methods
of palm kernel oil by hexane is better than mechanical extraction.
