Abstract

Oil extraction was carried out using two different extraction method (water and solvent) and the yield for different method were obtained. The free fatty acid for different oil was also determined immediately after extraction and also on storage for two weeks. The solvent method was carried out in soxhlet apparatus while hot water was used to extract oil from decorticated sesame seed. The yield from both method varied and the

Crude fiber from one variety of Nigerian black sesame was reported to have 19.6% of crude fiber, whereas one variety of Taiwanese black seed contained only 2.81% of crude fiber. The carbohydrate content ranged from 3% to 14%. Sesame seed has about 17% seed weight as hull, which is high in oxalic acid (2_3%), calcium, and crude fiber. Oxalic acid could form complex with calcium and reduces its bioavailability; indigestible fiber would reduce the digestibility of protein. Sesame oil belongs to the oleic-linoleic acid group. It has less than 20% saturated fatty acid, mainly palmitic (7.9_12%) and stearic (4.8_6.1%) acids. Oleic acid and linoleic acid constitute more than 80% of the total fatty acids in sesame oil. Unlike other vegetable oils in this group, the percentages of oleic acid (35.9–42.3%) and linoleic acid (41.5–47.9%) in the total fatty acids of sesame oil are close.

1.1 Objective of The Study

The purpose of this study is to;

• Extract oil from sesame seed using Water and Solvent extraction. • Compare the effects of methods of extraction on the extracted oils • Determine the free fatty acid contents of the oils extracted. • Determine the effectiveness of storage condition on the extracted oil.
