Isolate by ultrasound (UDLPI) increased the protein yield over control (DLPI). Surface hydrophobicity of UDLPI increased by 39.5% as compared to DLPI. Particle size of UDLPI reduced by 12.3% with a narrower size distribution. UDLPI showed partial protein hydrolysis and unfolding by spectroscopy analysis. UCLPI demonstrated better solubility and foaming expansion than DLPI.
