    Proximate, Mineral Contents and Physicochemical Properties of Chrysophyllum Albidum (African Star Apple) Kernel Flour and Oil
    (Department of Chemistry, Nasarawa State University, Keffi, 2019-06-04) Audu, Saratu Stephen; Beetseh C.; Edward-Ekpu, DU; Ewuga, A.A.
    The flour and oil ofthe kernel of African Star Apple (Chrysophyllum Albidum Linn.) sourced from Maraba Gurku township of Nasarawa state was analysed to determine their potentials for industrial and human consumption. Standards methods were used to determine the proximate and mineral contents ofthe flour and physico- chemical properties ofthe oil. The results obtained from the Proximate Analysis shows the kernel has a moisture content of 10.06±0.08 %, Ash content of2.72±007 %, Crude lipid of 13.31±008 %, Crude Protein of7.92±0.00 %, Crude Fibre of 1.59*0.00 % and Carbohydrate of65.41±0.05 %. This suggeststhat the flour can be a used as an alternative to cereals in compounding animal feed. The results from the Mineral Analysis showed the kernel has 0.01 mg/g ofcopper, 0.01 mg/g ofIron, 37.50 mg/g ofphosphorus, 57.37 mg/g ofcalcium and 0.44 mg/g magnesium. The Calcium-Potassium Ratio indicates the flour is a good source of calcium for bone formation. The Physicochemical analysis showed the oil has an Acid Value of33.12±0.25 mgKOH/g, a Saponification Value of 184.90±0.29 mgKOH/g, an Iodine Value of60.05±0.02 mgKOH/g, a Free Fatty Acid Value of 16.05±0.14 mgKOH/g, Peroxide Value of 2.10±0.10 m Eq/kg, Moisture of 3.36±0.08 %, Unsaponifiable Matter of5.26±0.05 g/kg and an Ester Value of 15I.78dk0.15 mgKOH/g. The quality ofthe kernel oil falls below the standard for edible oil but the oil may be useful in the paint and cosmetic industry.
