To improve functional properties of food proteins, homologous or heterologous β-casein and 11S globulin (glycinin) from animal and vegetable proteins, respectively, were bio-hybridized using transglutaminase (MTGase). Susceptibility was confirmed by SDS-PAGE, particle size analyzed, and emulsion stability tested using Reddy and Fogler method. To determine how bio-hybridized protein influences emulsion stability, protein bound on oil droplet was investigated using Scanning Electron Microscopy (SEM).
