Proximate Composition, Nutritionally Valuable Minerals, Protein Functional Properties and Anti-Nutrient Contents of Mucuna Preta, Mucuna Ghana and Mucuna Veracruz Mottle

I.A. Amoo, V.N. Atasie and O.O. Kolawole    

Abstract: 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.
