Abstract

Physical properties, chemical composition and nutritional quality potentials of the seeds of Lonchocarpus sericeus (cube root) were investigated. The water absorption properties of the seeds were measured both gravimetrically as hydration capacity (0.02±0.005 g/seed), and hydration index (0.06±0.01) and volumetrically as swelling capacity (0.01±0.00 mL/seed) and the swelling index (1.2x10-4±0.00). A 100 g of seeds contained 17.53±2.08, 38.83±4.16, 3.18±0.19, 24.93±3.21, 29.96±3.82 and 3.10±0.89 g moisture, crude fibre, ash, crude fat, crude protein, and nitrogen free extract (NFE), respcetively; 149.20±0.24 kJ gross energy, 848±16.1, 722±10.0, 720±9.1, 230±8.2, and 224±8.1 mg Fe, Mn, Zn, Cu and Na, respectively per 100 g seed sample. The seed also contained 3.14±0.12, 2.18±0.32 and 4.30±0.06 mg/g tannin, oxalate and saponin`, respectively. The essential-to-total amino acid ratio (E/T, %) is 44.10%; average predicted protein efficiency ratio (PER) is 2.70, while the predicted biological value (BV) is 34.85. Elaidic acid is the most significant fatty acid (46.32%) found in the seeds with a total saturated and unsaturated fatty acids of 46.14% and 50.50%, respectively. The oil of L. sericeus is equally rich in bioactive compounds including tocopherols, sterols, phospholipids, tocotrienols and terpenoids with a concentration of 50.09, 479.13, 333.14, 1.34 and 3.33 x 10-4 mg/100g, respectively. L. sericeus seed would be a potential source of dietary energy, industrial oil, bioactive compounds and vegetable protein.
