Influence of moderate electric field on sodium caseinate structure and its techno-functionality

This study aimed to evaluate the effect of moderate electric field (MEF) treatment, as a non-thermal technology, on structure and techno-functionality sodium caseinate. Colloidal dispersions caseinate were subjected different MEF processing conditions (2.56 V cm−1 for 1 2 h, 38.46 5 20 s) their structural, physical, emulsifying film-forming characteristics assessed. The Fourier transform infrared (FTIR) analysis showed higher β-structures reduction in random coil conformation after MEF. MEF-treated exhibited smaller particle size developed emulsions with physical stability. process increased tensile strength (by 6.52–27.37%) stretchability 12.17–54.30%) film. A glass transition temperature MEF-processed films was confirmed by modulated differential scanning calorimetry (MDSC) profiles. electron microscope (SEM) images more uniform microstructure treated films. results suggest that may be efficiently applied mild modification resulting its property improvement.
