In this study, extraction of rice bran oil has been studied and the fatty acids<br />

composition in rice bran oil has been determined. Experiment was conducted using<br />

Soxhlet apparatus and rice bran oil was extracted using hexane, ethyl acetate and<br />

ethanol as the solvent. It found that hexane was provided the highest oil yield. The<br />

results of Gas Chromatography Flame Ionization Detector (GC-FID) shown that oleic<br />

(C18:1), linoleic (C18:2) and linolenic (C18:3) acids are the major fatty acid<br />

constituents in extracted rice bran oil. All samples were further analyzed using FTIR<br />

spectrometer. The spectra revealed the peaks within the range of 3000cm -1 and<br />

1710cm -1 were attributed to cis =C-H stretch and C=O stretch and can be used as<br />

indicative for the presence of unsaturated fatty acids in rice bran oil. Its applications<br />

in the chemical industry have high potential because chemical modification on the<br />

double bond in the unsaturated fatty acid can be explored to produce oleochemical<br />

products, polyols.<br />
