1.3 STATEMENT OF THE PROBLEM
In
the market today, most vegetable oils solidify at a low temperature of
less than 250c. This work is to process and refine edible and quality
soyabean oil that will not undergo solidification at a low temperature.
1.4 OBJECTIVES OF THE STUDY
The objective of refining and processing fats and oils include:
ï‚·
Removal of free fatty acids, phospholipids (gums) colour and
off-flavour/odour compounds and toxic substances to produce light-
coloured and bland products with long shelf lives.
ï‚· Obtaining a mixture of the triacyl-glycerols with the desired solid content profiles over the range of product use.
ï‚· Preparation and storage of semi-solid products with desired textures.
1.5 SCOPE OF THE STUDY
The
crude oil extracted from soyabean needs further treatment to convert it
to a bland, stable, nutrition products that is used to manufacture
margarine, shortening, salad and cooking oil, mayoniaise, food products,
Olechemicals.
This study entails the process of producing good
quality oil through caustic/alkali refining process which is going to be
compared with other good quality products in the market like grand
product etc.

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, ...
