African grapes (Lannea microcarpa) fruits: the nutritional compositions
Studies on nutritional composition of African grapes (Lannea microcarpa) fruits pulp was carried out using standard analytical methods. The result of proximate composition in mg/100g revealed the following: moisture (70.55 ± 2.56), ash (3.48 ± 0.81mg), crude fiber (5.21 ± 1.67), crude protein (8.71 ± 1.98), crude lipid (1.87 ± 0.34) and carbohydrate (80.73 ± 6.81) as well as calorific value (374.59 ± 4.32KJ/100g). The fruits pulp also contain reasonable amount of both macro and micro minerals element needed in diet with potassium concentration of (450 ± 3.87mg/100g), phosphorus (6.14 ± 0.89mg/100g), sodium (15.10 ± 1.70mg/100g), calcium (35.00 ± 1.90mg/100g), magnesium (58.00 ± 3.23mg/100g), iron (38.21 ± 2.67 mg/100g),manganese (3.10 ± 0.45mg/100g) as well as zinc (14.14 ± 2.98mg/100g). The anti-nutrients factors (in mg/100g) indicate the presence of tannins (4.17 ± 0.61), oxalates (12.14 ± 2.32), phytates (40.50 ± 1.54), and saponins (2.16 ± 0.87). However, the calculated anti-nutrients to nutrients molar ratios are generally below the critical level known to inhibit the availability of some important minerals elements which suggest the potential safety of using the fruits pulp as nutrients supplement.
