solvent. It is also called leaching. The chemical extraction using n-hexane method results in the highest
oil yield which makes it the most common method. Three samples of grated kernels were used to perform
the oil extraction process. For chemical oil extraction, dried seed kernel samples were ground using a
blender and coffee grinder to obtain a fine consistency to maximise particle surface area. The ground
kernels were put into conical flasks in which n-hexane were added at a ratio of 2:1 (ml hexane: grams
kernel).
