Physicochemical and Functional Properties of Moringa Seed Protein Treated with Ultrasound
© 2024 The Authors. Published by American Chemical Society..
Functional and structural properties of Moringa protein concentrate (MPC), obtained from defatted Moringa oleifera seed, were investigated after treating it with an ultrasonic technique. For this purpose, dried M. oleifera seed powder was defatted and subjected to a simple protein precipitation method to generate a MPC with 73.2% protein contents. Then, a Box-Behnken design was applied to optimize the sonication treatment of MPC where ultrasound amplitude (20-80%), treatment time (5-25 min), and solute-to-solvent ratio (0.1-0.3 g/mL) were studied as factors that influence the protein solubility (PS), emulsion capacity (EC), and foaming capacity (FC) of MPC. The optimal conditions were amplitude of 58%, time of 18 min, and solute to solvent ratio of 0.18 g/mL. At these conditions, PS, EC, and FC were increased to 42, 33, and 73%, respectively, in comparison to untreated one. The structural modification by ultrasound was further confirmed by using Fourier transform infrared spectroscopy which illustrated the MPC modification through the changes in the peak width of amide-I band. Similarly, the intrinsic fluorescence spectral signature also showed a significant increase in the amino residues of MPC. In conclusion, the exposure of hydrophilic groups and the alteration of secondary and tertiary structures induced by ultrasonic treatment improved the functional characteristics of MPC.
