The Physiochemical Analysis Of Thermoxidized Soyabean-Oil And Its Effect On Growth In Rats


OA Alabi

Abstract

Physiochemical characteristics of Fresh and thermoxidized soyabean –oil were studied. Thermoxidized soyabean-oil was found to possess higher percentage of free fatty acids and peroxide value when compared with the fresh soyabean-oil. The rats fed with diet containing 5% and 15% level of thermoxidized soyabean-oil did not show any sign of retarded growth, but the weight gain was lower than those fed with Fresh soyabean-oil. The reason could possibly be as a result of mild accumulation of peroxide as well as gross accumulation of decomposition products of lipid peroxidation which are known to be toxic.
