Refining of crude soya bean oil extracted from soya bean seed using alkali /caustic refining method
ABSTRACT
This research is on Refining of crude soya bean oil extracted from soya bean seed using alkali /caustic refining method. 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.

THE OXIDATIVE STRESS STATUS OF RATS FED ON OIL BEAN SEED MEAL
ABSTRACT
This study was on oxidative stress status of rat fed with Pentraclethra macrophylla, otherwise known as African oil bean seed oil in English or Ugba in Igbo. Sixteen male rats were distributed into four groups. 1 control, then group 2, 3, and 4 as test groups. They were fed with their formulated meal 5, 10, 20 inclussions for 28 days. Group 1 was the control and were fed with the normal feed, while group 2, 3 and 4 which were the test groups were fed with test feed formula.. The parameters determined were MDA concentrations and catalase activity. Serum MDA significantly increased plt;0.05 while the catalase activity significantly decreased plt;0.05. This finding may be clinically significant to individuals with predisposition to increased generation of reactive oxygen species ROS and other degenerative diseases.
