Abstract

Acacia nilotica seed (ANS) and Parkia biglobosa seed (PBS) are underutilised legume found to have health benefits and functional properties. Th is study determined nutrient composition of A . nilotica and P. biglobosa seed s . ANS and PBS were collected and processed properly for c hemical analysis. The proximate, minerals, vitamins, essential amin o - acids, and antinutri ent composition were analyzed to ascertain nutritional attributes and its potential in promoting dietary diversity . The raw and fermented A . nilotica se eds contained in g/100 g , protein (12.88 to 15.3 8), fat (3.29 to 4.91), ash (5.24 to 6.84), dietary fibre (1.98 to 2.66) and available carbohydrate (69.63 to 71.73), whil e the FPB contained in g/100 g, protein (18.30), fat (9.20), ash (8.69), dietary fibre (2.61), and available carbohydrate (56.27). The fermented A . nilotica (FAN) seed contained all the nine (9) essential amino acids. The raw and fermented ANS contained in mg/100 g , iron (9.67 to 12.23), zinc (0.69 to 1.13), calcium (0.17 to 0.22), sodium (0.14 - 0.21 ) while the F PB seed contained 14.86, 1.59, 0.25, and 0.24 , respecti vely. FAN and FPB contained in μg/100 g, vitamin A (148.79 and 197.81), vitamin E (15.90 and 24.69) and vitamin K (1.41 and 1.63) , respectively. The levels of antinutrient factors in all the samples were not significant. Fermented A . nilotica seed contained adequate level of some micronutrients and essential amino acids. Consumption of the seed should therefore be promoted.
