  Proximate, physico-chemical and elemental analysis of groundnut were determined. The results showed that the groundnut oil contained 47.00% fat, 38.61% protein, 5.80% moisture, 1.81% carbohydrate, 3.70% crude fibre and 3.08% ash. Minerals (mg/100g) included: Na (42.00±0.71), K (705.11±0.86), Mg (3.98±0.04), Ca (2.28±1.94), Fe (6.97±1.62), Zn (3.20±0.11), P (10.55±0.68). The physico-chemical characteristics showed; saponification value, 193.20mgKOH/g, iodine value 38.71 (g/100g), acid value 5.99 (mgKOH/g), free fatty acid (mgKOH/g) 3.01 peroxide value 1.50 (meq/kg) and refractive index 1.449. The predominant fatty acid was found to be oleic acid (41.11%). The groundnut can thus be considered as a good source of protein with high nutritional value.

  Results of the proximate composition, functional properties and physico chemical properties of mucuna ghana, mucuna preta and mucuna Veracruz mottle is reported. The ranges are; ash (3.17-4.33), moisture (8.50-8.85), crude protein (30.92-33.25) and crude fat (46.20-49.34). Mineral contents showed phosphorus to be most abundant while manganese and copper were least. Lead was not detected. Functional properties of the protein showed a good Water Absorption Capacity (WAC) ranges (145-160) and Oil Absorption Capacity (OAC) ranges (130.10-138.23). The foaming capacity (17.00-25.00), mucuna preta was least and mcuna ghana highest. The Oil Absorption Capacity (OAC) (130.10-138.23) with mucuna ghana highest and mucuna veracruz mottle least. The Least Gelation Concentration (LGC) and emulsion capacity (ES) are relatively good. The Foaming Capacity (FC) after 2 h showed appreciable and acceptable values (17.00-25.00) in which mucuna preta was least and mucuna ghana was highest. The Foaming Stability (FS) values were also within acceptable ranges (9.0-12.50). Emulsion stability (59.00-66.00) has mucuna ghana least and mucuna veracruz mottle highest. Plots of the protein solubility against pH showed protein to be soluble at both acidic and alkaline regions. Anti-nutrients in the samples showed tannic acid range (8.54-10.30), Oxalate mg/g (6.78-8.31) and phytate mg/g (55.11-85.47). The ranges were however within acceptable values.

  Proximate, physico-chemical and elemental analysis of palm Kernel nut were determined to contain fat/oil 42%, crude protein 7.01%, moisture 6.5%, crude fibre 11.09% and carbohydrate (by difference) 33.40%. The elemental composition (mg/100 g), included :Na (37.00±0.40), K (39.51±0.22), Mg (3.60±0.1), Ca (19.0±0.42), Fe (20.04±0.28), Zn (2.82±0.30), P (3.4±0.00). The result of the physico-chemical properties of the palm kernel oil are:-saponification value (232.815 mgKOH/g), refractive index (1.453), iodine value (41.24g/100g), acid value (11.60 mgKOH/g) and peroxide value (1.70meq/kg).
