    (3.14±0.26 mg/KOH/g). These values suggest that the extracted oil from the fruits and kernel will be good for industrial purposes. Results show that palm kernel cake contained high amounts of crude proteincrude proteinSubject Category: Miscellaneous

    (9.08±0.03 g/100 g). The most predominant mineral in the cake was potassium (330.74 mg/100 g) while minerals like cobalt and copper were not detected. They also contained moderately high amounts of other minerals (sodium, calcium, magnesium, zinc and phosphorus), which qualifies as potential future food supplements. The concentrations of four anti-nutritional factors determined were tannic acid (0.35-0.44%), phytin phosphorus (6.50-6.73 mg/g), phytic acid (23.07-23.90 mg/g) and oxalate (5.04-5.22 mg/g).
