Title : Physicochemical and structural property of balanites aegptyiaca membrane extracted products
Abstract:
Demands for protein ingredients continues to rise globally. This study reports the physicochemical and structural properties of plant Balanites aegptyiaca Del proteins using 5 KDa membrane molecular cut off. The meal after defatting Aduwa Protein Concentrate (APC) and membrane salt and alkaline soluble concentrates by membrane ultrafiltration were obtained; mNaOH and mNaCl concentrates. Results revealed that APC had a high protein content (74.05%) compared to mNaCl (48.18%) and mNaOH (40.74%) samples. The mNaCl revealed excellent essential amino acid, macro and micro elements. Near-UV circular dichroism spectra, thermal properties and heat of coagulation revealed that mNaCl had better properties and a native tertiary conformation, while APC and mNaOH revealed unfolded structures. The APC and mNaCl and samples could improve surface related properties and better ingredients for beverage, pharmaceuticals and food processing sectors.
