| Abstract: | Karanja seed(Pongamia glabra) oil contains toxic flavonoids including 1.25% karanjin and 0.85% pongamol. After refining the oil resembles peanut oil in
composition and is free from toxic flavonoids, bitterness and unpleasant odors. Akashmoni seed(Acacia auriculaeformis) oil is rich in stearic acid (31%), and nearly two-thirds of its glyceride is GS2 U (disaturated monounsaturated), mostly SOS (saturated-stearic acid and unsaturated-oleic acid). Nutritional evaluations
of these two refined seed oils were carried out in rats by feeding the respective oils and peanut oil as control at 10% level
in a 20% protein diet for 12 weeks. The animals fed karanja oil showed poor growth performance, altered lipid metabolism and
fatty infiltration in liver. Akashmoni oil in the diet of rats did not reveal growth retardation or any abnormalities in evaluations
of lipid parameters of serum and liver or histopathological findings. The results of this study indicate that refined karanja
oil is toxic to rats and may not be desirable for edible purposes, while akashmoni oil may be desirable. |
