Proximate and Mineral Composition of the Pulp of Chrysophyllum albidum Fruit
The proximate composition of Chrysophyllum albidum fruit pulp was determined. Mineral elements were determined using a tri-acid digestion method. The result of the proximate composition of the fruit pulp showed moisture content (64.00 ± 0.02%), ash (3.00 ± 0.02%), lipids (8.50 ± 0.02%), crude fibre (4.00 ± 0.02%), crude protein (0.24 ± 0.03%) and soluble carbohydrate (20.26±0.03%). The energy value of the fruit was found to be (663.12±0.60%kJ/100g) in the fruit pulp. Similarly, mineral analysis revealed potassium with (256.57± 5.77mg/100g), sodium (40.00 ± 0.00mg/100g), phosphorus (2.21 ± 0.03mg/100g), calcium (61.67±5.77mg/100g), magnesium (33.33 ± 20.21mg/100g), copper (0.94 ± 0.20mg/100g), zinc (0.26 + 0.10mg/100g), and iron (3.46+ 0.06). Others include heavy metal such as lead (0.09 ±0.08mg/100g), chromium (6.83± 6.26/100g) and cadmium was not detected. The pulp also contained appreciable amount of vitamin C (3.70 ± 0.17mg/100g). The results showed that the fruit pulp of Chrysophyllum albidum contained essential nutrients and mineral elements.
