  • Abstract:

The nutritional compositions and amino acid profile of three underutilized legumes (Yard bean, Black bean, and Urad bean) seeds were evaluated using standard methods. The proximate compositions (%) of the seed showed moisture content (11.49, 8.87 and 9.41), crude protein (46.25, 35.98 and 31.91), carbohydrate (37.13, 48.27 and 45.89), crude fat (1.28, 1.20 and 1.26), ash (4.83, 5.64 and 5.13), crude fiber (0.39, 0.33 and 0.33) and energy (345.74 kcal/100g, 360.31 kcal/100g and 347.17 kcal/100g). Mineral compositions (mg/L) of the seeds indicated sodium (31.23, 30.46, and 29.19), calcium (593.27, 587.11 and 595.09), potassium (41.68, 46.07 and 52.11), magnesium (18.06, 32. 51 and 20.62), iron (7.55, 13.13 and 11.06), zinc (2.61, 7.71, and 3.79), copper (0.15, 0.93, and 0.75), nickel (1.02, 2 .87 and 1.01) and cadmium was below detection limit in Black bean with (0.14 and 0.01) in Yard bean and Urad bean. Lead was also below detection limit in all the bean samples. The amino acid profile of the seeds showed concentration (g/100g protein) of total amino acids (114.65, 90.74 and 112.39), total essential amino acids (51.23, 35.00 and 48.82), total non - essential amino acids (63.40, 55.73 and 63.96) and total sulphur amino acids (11.78, 2.36 and 9.96).This implies that the three underutilized legumes are highly nutritious and contained appreciable amount of minerals and amino acid that the body require for normal physiological function.
