ABSRACT - [ Total Page(s): 1 ]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 res

CHAPTER ONE - [ Total Page(s): 3 ]The soap stock can be dried if refining is done adjacent to an extraction plant or acidified again to remove fatty acids and sold to the olechemical industry. The oil is then water washed and centrifuge one or two times to remove residual soaps.According to GS Breck and S.C Bhatia, a total degumming process for removing essentially all the phosphatide from soyabean oil using first an acid and then an alkali and two centrifuges has shown higher yields than conventional refining. This process however, does not remove prooxidant metals efficiently and for this reason has not found ... Continue Reading
