ABSTRACT
Rapeseed oil is one of the important and cheapest vegetable oil in Bangladesh and many other countries. It is commonly used as cooking oil in Bangladesh particularly in rural areas and also used as other food items. This study evaluated the physiological effects of four type’s rapeseeds namely Mustard (Wild), Mustard (hybrid), Rai (Wild), Rai (hybrid) oil on six strains of bacteria in addition to studying the effects of two varieties of rapeseeds oil Mustard (Wild) and Rai (hybrid) oil on Wistar rat’s organs including liver, kidney, heart and skeletal muscles. Firstly, we examined the effects of these Rapeseeds oil on bacteria and found that these Rapeseeds oils possess antibacterial activities. Six bacterial strains such as B. subtilis, S. lutea, X. campestris, E. coli, K. Pneumonia, P. denitrificans was used to test the effect of these rapeseeds oil and observed that rapeseed oil showed inhibition against tested microorganisms in a concentration-dependent manner. Finally, the effects of oil obtained from these two varieties were investigated after feeding rats for 8 weeks. Male Wistar rats were divided into three groups, each group contains 4 rats. Group A was considered as a control diet group, while Group B was a mustard (Wild) oil group and Group C was the Rai (hybrid) oil group. Group A was containing 0.6gram oil plus 14.4gm diet. We found that rats of both experimental groups exhibit weight loss, reduction of food efficiency ratio, and increase cardiac and hepatic enzymes including CK-MB, ALP, SGPT, and SGOT compared to the rats fed a controlled diet. Furthermore, we also found that the body weight loss, food efficiency ratio markedly decreased, and tested enzymes increased in rats fed Mustard (Wild) oil compared to rat fed Rai (hybrid) oil.
Keywords: Rapeseed, erucic acid, food efficiency ratio, vegetable oil, Brassica spp, and Wister Rat organs.
