ABSTRACT
African walnut was analysed for its proximate composition, minerals, and chemical analysis of the oil for both raw and boiled sample. Its moisture content is 4.3 and 5.0, Ash Content 7.0 and 6.2, crude protein 17.73 and 25.27, crude fibre 6.5 and 6.0, crude oil 56.55 and 53.95, carbohydrate 7.92 and 3.58 respectively. The African Walnut contains considerable amount of calcium, magnesium, manganese, Iron, Zinc and lead was not detected. The Chemical analysis of oil extract include the specific gravity, saponification, Acid value, free fatty acid, ester, peroxide value and viscosity and the values are 0.8911 and 0.8825, 82.05 and 84.15, 3.60 and 2.80, 2.5 and 1.97, 78.45 and 81.35, 9.40 and 9.35, 3.76 x 102and 3.74 x 102, 1.5.12 and 1.520 respectively.
