Abstract:

Oil in black sesame and white sesame seeds was obtained by Soxhlet extraction and esterfied with methanol solution of potassium hydroxide for analyzing fatty acid composition by gas chromatography-mass spectrometry (GC-MS). There were 21 and20 fatty acids identified in black sesame and white sesame seed oil, of which, unsaturated fatty acids accounted for 71.30% and 73.58%, respectively.

Key words: black sesame, white sesame, fatty acid, GC-MS
