This project work studied the refining of crude soya bean oil extracted
from soya bean seed using alkali /caustic refining method. The work
was carried out using phosphoric acid for the degumming
/pretreatment process and sodium hydroxide for the neutralization
/refining of the oil. Certain tests were carried out on both the crude
and refined oil such as saponification value, acidic value, iodine value,
specific gravity and viscosity, the results obtained after the tests
include 42.075, 164.28, 589.05, 0.8944 and 0.038 respectively for
refined oil and 44.88, 109.52, 448.8, 0.8148 and 0.035 respectively
for the crude oil
