Abstract:
Soya bean oil was extracted from the seed of soya bean (glycine max) using solvent extraction
method, which required the optimum maximum yield of each of the solvent used per parameter.
The parameters considered include, moisture content, ash content, crude fat (liquid), crude fibre,
crude protein and carbohydrate content. The results obtained from the proximate analysis of each
of the parameter used, are; moisture content, 8.3-0 + 0.04 (petroleum ether) and 5.0 -+ 0.04
(isopropanol/Alcohol); Ash content, 9.01 -+ 0.1 (petroleum ether) and 6.30+0.03 (isopropanol),
crude fat (liquid) is 21.47 -+ 0.08 for isopropanol, crude fat is 19.02 -+ 0.04, crude fibre is 2.45
-+ 0.03, for isopropanol, crude fibre is 1.35 -+ 0.23, crude protein 37.51 -+ 2.46, isopropanol
crude protein is 34.60 -+ 0.12 and the carbohydrate content for petroleum ether is 21.26% while
for isopropanol/alcohol is 33.72%. The above results, which are expressed as mean -+ S.E.M
indicates that protein has a high percentage yield than other parameters, and carbohydrate
content in isopropanol/alcohol has higher percentage yield than petroleum ether therefore, the
totality of the result indicates that petroleum ether has higer oil yield than isopropanol/alcohol of
above 95%. |
