| Summary: | A laboratory scale for extraction and analysis of date palm kernel oil (DPKO) was
conducted by date palm kernel (DPK) from two types of date which were Deglect Noor
(DN) and Moshkan (MO). The moisture content for DN and MO were determined to be
4.176 % and 5.335% respectively. The extracted oil was then analyzed for acid value
(AV), unsaponifiable oil and total phenolic content. The AV for DN and MO were found
to be 1.71 ml/g and 2.19 ml/g respectively. The total phenolic content of the extracted oil
for DN and MO were 0.988 mg/ml and 0.958 mg/ml respectively while for the
unsaponified oil, the total phenolic content were 0.67 mg/ml and 0.84 mg/ml
respectively. Central Composite Design (CCD) was used for optimization and the
maximum oil extraction was 9.67%, achieved at 10 g and 5 hours for DN and 7.30% for
MO which achieved at 6g and 4 hours. Generally, DN had high percentage of oil and
total phenolic content in extracted oil than MO. However, MO had high percentage of
moisture content, acid value and total phenolic content. Instead of chemical difference,
their physical variation also obviously could be observed. The color of DPK for DN was
less brown than MO and the color of oil for DN was more yellow than that of MO. |
