Abstract

The nutritive value of Baobab fruit (Adansonia digitata).

Abstract

The seed, powdery pulp and hard husk of Adansonia digitata fruit was analysed. The proximate moisture contents of the seed, pulp and hard husk were 6.12±0.14, 6.21±0.02 and 3.11±0.17%, respectively. The husk had a proximate ash content of 4.21±0.31% and a crude fibre content of 35.3±0.47%, which were higher than those of the seed and pulp. The proximate crude protein content of the seed was 21.42±0.34% while that of the pulp and husk were 10.90±0.30 and 2.41±0.17%, respectively. Proline and valine were the limiting amino acids. The proximate oil content of the seed was 17.51±0.13%. The oil had the following physico-chemical properties: peroxide value 5.14±0.12, iodine value 86.41±0.64, acid value 7.79±0.33 mg/KOH g-1, saponification value 132.68±2.14 and free fatty acid 6.40±0.18. The oil contained 8 fatty acids which were composed of 82% unsaturated acids. The 5 sugars identified in the pulp were glucose, fructose, sucrose, maltose and raffinose. These sugars accounted for 43.62±0.17% of the carbohydrate content. Potassium and sodium were the most abundant elements in the seed, pulp and husk.
